# HLS input requirements
HLS input requirementsAWS Elemental MediaConvert now supports HLS inputs

Learn about the package requirements, compatible features, and feature restrictions when you use an HLS package as input to MediaConvert.

 When you specify an HLS package as an input for your MediaConvert job, you need to specify the correct input file URL and ensure that the HLS input package conforms to the requirements listed on this page. 

You can specify either a multivariant or variant playlist. If the manifest is a parent that lists multiple child manifests, MediaConvert uses the variant playlist with the highest bandwidth as the input source.

## HLS input requirements
HLS input requirements

Your HLS input must conform to the following requirements:


|  |  | 
| --- |--- |
| Input requirement | Details | 
| Video container | MediaConvert supports MPEG-2 Transport Stream (MPEG-TS) files for input HLS media segments. | 
|  HLS manifest `EXT-X-VERSION`  | MediaConvert supports EXT-X-VERSION values of 4 or lower within input HLS manifests. | 
|  HLS manifest `EXT-X-ENDLIST`  |  Include `EXT-X-ENDLIST` or `EXT-X-PLAYLIST-TYPE: VOD` in your input manifest. Manifest files must not change after you submit your job.  | 
|  HLS manifest `EXT-X-PLAYLIST-TYPE: VOD`  |  Include `EXT-X-ENDLIST` or `EXT-X-PLAYLIST-TYPE: VOD` in your input manifest. Manifest files must not change after you submit your job.  | 
| HLS manifest EXT-X-BYTERANGE | If present, the start of the first subrange must be 0 and the following subrange segments must continue the former one. | 
| HLS manifest EXT-X-KEY |  If present, `EXT-X-KEY: METHOD` must be set to `NONE`. MediaConvert does not support HLS encrypted inputs.  | 
| HLS manifest ignored tags |  MediaConvert ignores the following tags: [\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/mediaconvert/latest/ug/using-hls-inputs.html)  | 
| Discontinuities |  If present, any discontinuities must start at the beginning of a segment. MediaConvertdoes not support input discontinuites in the subrange of a segment.  | 
| Accelerated transcoding requirements | EXTINF duration must be specified using a decimal floating-point, with enough accuracy to avoid perceptible errors when segment durations are accumulated. | 

## MediaConvert features compatible with HLS inputs
Compatible features

With HLS inputs, you can use the following input features:
+ Input clipping
+ Input stitching
+ Image insertion
+ Embedded input captions selectors

## HLS input feature restrictions
HLS input feature restrictions

When your input is an HLS package, your job is restricted in these ways:
+ Your input package must conform to the requirements listed in [HLS input requirements](#hls-input-package-requirements).
+ Your input segments can't be encrypted with DRM. For example, your inputs can't be encrypted with Apple FairPlay DRM.
+ You can use only embedded input captions.

# Alternate HLS audio rendition requirements
Alternate HLS audio rendition requirements

With HLS rendition groups, you can use the audio selector settings to indicate which alternate audio rendition you want MediaConvert to use. To be eligible for selection, your alternate audio renditions must conform to the following requirements:
+ The renditions must be included in `EXT-X-MEDIA` tags in the input multivariant playlist.
+ The `EXT-X-MEDIA` tags must contain a unique combination of GROUP-ID, NAME, and LANGUAGE values..
+ Audio must be in one of the following supported audio codecs: AAC, Dolby Digital (AC3), Dolby Digital Plus (EAC3), or MP3.
+ The variant playlist for your alternate audio rendition must be included in the multivariant playlist that you used for your Input file URL (FileInput)

 When you specify audio selector settings to identify an alternate audio rendition, the audio selector looks for a matching `EXT-X-MEDIA` tag in the multivariant playlist.

You can use one or more selector settings at a time. For example, given the following `EXT-X-MEDIA` tags, you can identify the audio rendition by the name (RenditionName) or language (RenditionLangageCode) because these are both unique values across the tags.

`#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio",CHANNELS="2",NAME="English",LANGUAGE="eng",DEFAULT=YES,AUTOSELECT=YES,URI="english_audio.m3u8"` 

`#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio",CHANNELS="2",NAME="Japanese",LANGUAGE="jpn",DEFAULT=NO,AUTOSELECT=NO,URI="japanese_audio.m3u8"`

However, because the group ID (RenditionGroupID) is the same for both tags, you can't use that alone to identify an audio rendition. You must use the group ID in combination with another value from the `EXT-X-MEDIA` tag to identify the audio rendition that you want MediaConvert to use.

If you don't specify audio selector settings, the audio selector looks for audio that's muxed into the video segments. If the video segments don't contain audio, the audio selector uses the first alternate audio rendition from the input parent manifest.

# HTTP input requirements
HTTP input requirementsHTTP inputs to AWS Elemental MediaConvert

You can now specify an HTTP(S) URL for your primary inputs to MediaConvert transcoding jobs. Learn about HTTP(S) input requirements.HTTP inputs to AWS Elemental MediaConvert can now use redirects

See the updated requirements for providing your inputs to MediaConvert through HTTP.

When your input file source is HTTP(S), you specify the URL rather than an Amazon S3 path. Requirements for using HTTP(S) for input are as follows:
+ All input files must be publicly readable.
+ The HTTP(S) server must not require authentication.
+ The HTTP(S) server must accept both HEAD and range GET requests.
+ The URL that you specify can't include parameters.

If your HTTP(S) input uses redirection, it must follow these restrictions:
+ You can redirect only once from the URL that you provide as your input. You can't redirect to a URL that, in turn, contains a redirect.
+ The HTTP(S) status response code from the initial server must be either 301 or 302.
+ The HTTP(S) response from the initial server must use its `Location` headers to provide the URL that it's redirecting MediaConvert to.

# Supported input formats for audio-only workflows


When you create audio-only outputs, MediaConvert supports audio-only inputs with the following containers and codecs.

Some containers and codecs have additional restrictions. For more information about the audio container or audio codec choose its link in the following reference table. Or see [Supported containers and codecs reference tables](supported-containers-codecs-details.md).

# 8K output requirements


When your MediaConvert job has outputs with 8k (8192x4320) resolutions, your job is restricted in these ways:
+ You can't create Dolby Vision outputs.
+ You must send your job to an on-demand queue. Reserved queues can't run 8k jobs.

# Creating MXF outputs
Creating MXF outputsSupport for additional MXF profiles and automatic profile selection

Learn about creating MXF outputs with MediaConvert.Refined automatic MXF profile selection for MPEG-2 outputs

MediaConvert default automatic MXF profile selection now chooses the SMPTE-386 D10 profile when the output's encoding settings allow for it. Otherwise, MediaConvert chooses XDCAM RDD9. Learn the details about the required encoding settings for D10.

MXF is an output container format that carries video content for editing, archiving, and exchange. The MXF format is governed by a set of specifications, some of which define *MXF profiles*, also called shims. These MXF profiles lay out constraints on encoding settings including video codec, resolution, and bitrate.

To make sure that your outputs comply with these specifications, you can use the MediaConvert automatic profile selection. When you do that, MediaConvert automatically encodes the correct profile, based on the values you choose for your codec, resolution, and bitrate. For more information, see [Working with default MXF profiles](default-automatic-selection-of-mxf-profiles.md).

You can also explicitly choose your MXF profile. When you do so in the MediaConvert console, MediaConvert automatically populates the dropdown list for **Video codec** with only valid codecs. When you aren't using automatic profile selection, refer to the relevant specifications for constraints on your resolution and bitrate.

**Note**  
When you manually specify your MXF profile, you must set up your output in a way that is compatible with that specification. You can submit jobs with incompatible MXF profiles and encoding settings, but those jobs will fail.

Creating an MXF output

To set up a job with an MXF output, you create the output in the **File group** output group. Then specify MXF as the output's container.

**To set up your transcoding job with an MXF output (console)**

1.  Set up your job inputs and outputs as described in [Tutorial: Configuring job settings](setting-up-a-job.md). Put your MXF output in the **File group** output group.

1. On the **Create job** page, in the **Job** pane on the left, choose your output.

1. In the **Output settings** section, for **Container**, choose **MXF container**.

1. Optionally, specify values for the settings under **MXF container settings**:
   + **MXF profile**: To manually specify your MXF profile, choose it from the list. If you keep the default value, **Auto**, MediaConvert chooses your MXF profile based on your video codec and resolution. For more information, see [Working with default MXF profiles](default-automatic-selection-of-mxf-profiles.md).
   + **Copy AFD to MXF**: Ignore this setting unless you have AFD signaling set up in your output video stream. If you do, and you want that information in both your video stream and the MXF wrapper, choose **Copy from video stream**. If you want your AFD signaling only in your video stream, keep the default value **Don't copy**.

1. In the **Encoding settings** section, choose a video codec. 

   Your available choices in this list depend on what you choose for **MXF profile** in the previous step of this procedure:
   + When you keep the default value, **Auto**, for **MXF profile** then you can choose any video codec that is compatible with your output container.
   + When you choose a specific profile for **MXF profile**, then your choices for **Video codec** include only the codecs that are valid with that profile.

   

1. Optionally, specify your output video resolution for **Resolution (w x h)**. This is the other setting that MediaConvert uses when automatically determining your MXF profile.

   When you don't specify values for **Resolution (w x h)**, your output resolution is the same as your input resolution.

1. Specify your other encoding settings as usual. For information about each setting, choose the **Info** link next to the setting label. 

**To set up your transcoding job with an MXF output (API, CLI, or SDK)**

If you use the API, CLI, or an SDK, specify the relevant settings in your JSON job specification and then submit it programmatically with your job. For more information about submitting your job programmatically, see one of the introductory topics of the *AWS Elemental MediaConvert API Reference*:
+ [Getting started with AWS Elemental MediaConvert using the AWS SDKs or the AWS CLI](https://docs.aws.amazon.com/mediaconvert/latest/apireference/custom-endpoints.html)
+ [Getting started with AWS Elemental MediaConvert using the API](https://docs.aws.amazon.com/mediaconvert/latest/apireference/getting-started.html)
+ Use the MediaConvert console to generate your JSON job specification. We recommend this approach, because the console functions as an interactive validator against the MediaConvert job schema. Follow these steps to generate your JSON job specification using the console:

  1. Follow the previous procedure for the console.

  1. In the **Job** pane on the left, under **Job settings**, choose **Show job JSON**.

Find additional information, including where each setting belongs in the job settings structure, in the *AWS Elemental MediaConvert API Reference*. Links in this list go to information about the setting in that document:

**Output settings**
+ **Container** (`[container](https://docs.aws.amazon.com/mediaconvert/latest/apireference/jobs.html#jobs-prop-containersettings-container)`)
+ **MXF profile** (`mxfSettings, [profile](https://docs.aws.amazon.com/mediaconvert/latest/apireference/jobs.html#jobs-prop-mxfsettings-profile)`)

  For automatic profile selection, omit this setting from your JSON job specification.
+ **Copy AFD to MXF** (`mxfSettings, [afdSignaling](https://docs.aws.amazon.com/mediaconvert/latest/apireference/jobs.html#jobs-prop-mxfsettings-afdsignaling)`)

**Encoding settings**
+ **Video codec** (`[codec](https://docs.aws.amazon.com/mediaconvert/latest/apireference/jobs.html#jobs-prop-videocodecsettings-codec)`)

  This setting is a child of `outputs, videoDescription, codecSettings`.
+ **Resolution, w** (`[width](https://docs.aws.amazon.com/mediaconvert/latest/apireference/jobs.html#jobs-prop-videodescription-width)`)

  This setting is a child of `outputs, videoDescription`.
+ **Resolution, h** (`[height](https://docs.aws.amazon.com/mediaconvert/latest/apireference/jobs.html#jobs-prop-videodescription-height)`)

  This setting is a child of `outputs, videoDescription`.

In the MediaConvert console, **Auto** is the default value for **MXF profile**. When you set up your job by directly editing your JSON job specification, for automatic profile selection, don't include `profile` under `MxfSettings`.

# Working with default MXF profiles
Working with default MXF profiles

When you choose MXF as your output video container and keep **MXF profile** out of your job settings, MediaConvert automatically chooses your MXF profile for you and creates your output accordingly. How MediaConvert makes the MXF profile selection depends on your output video codec.

**Note**  
MediaConvert supports more MXF profiles through automatic profile selection than it does with manual selection.

**AVC (H.264), AVC Intra, and VC-3**  
For AVC (H.264), AVC Intra, and VC-3, MediaConvert selects the Generic OP1a profile, without regard for your output encoding settings.

**XAVC**  
For XAVC, MediaConvert selects the XAVC profile, without regard for your output encode settings.

**MPEG-2**  
For MPEG-2, MediaConvert chooses SMPTE-386 D10 when your output encoding characteristics conform to the D10 specification. Otherwise, MediaConvert selects the XDCAM RDD9 profile. The following table details the relevant encoding settings and the values that you must set to have MediaConvert automatically select the D10 profile.

**Note**  
For your output resolution and frame rate, you can specify an allowed value explicitly with the settings **Resolution** and **Frame rate**, or you can choose the value **Follow source** and use an input that has an allowed value.


| Setting | Allowed values for D10 profile | 
| --- | --- | 
|  Combination of: **Resolution** (wxh), **Frame rate**, **Interlace mode**  |  Allowed combinations: [\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/mediaconvert/latest/ug/default-automatic-selection-of-mxf-profiles.html)  | 
|  **GOP size**  |  1 frame  | 
|  **Profile**, for your video codec  |  4:2:2  | 
|  **Syntax** This setting is visible on the MediaConvert console when you choose MXF for your container, MPEG-2 for your video codec, and 4:2:2 for your codec profile.  |  D10  | 
|  Number of audio tracks Each output track is represented on the MediaConvert console as one **Audio** tab and in your JSON job specification as a direct child of `AudioDescriptions`.  |  [\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/mediaconvert/latest/ug/default-automatic-selection-of-mxf-profiles.html)  | 
|  Captions type You specify this on the MediaConvert console with the setting **Destination type**.  |  [\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/mediaconvert/latest/ug/default-automatic-selection-of-mxf-profiles.html)  |

# MXF output requirements
MXF output requirements

MediaConvert restricts MXF jobs in these ways:
+ You can put MXF outputs in a **File group** output group only.
+ You must choose a video codec that is supported with your MXF profile. The following table details which codecs are supported with each profile. For more information, see [List of codecs supported within each MXF profile](codecs-supported-with-each-mxf-profile.md).
+ You must set up your output audio tracks according to the requirements of the MXF profile. This applies whether you specify the profile or have MediaConvert automatically select it for you. For more information, see [Audio settings requirements for different MXF profiles](output-audio-requirements-for-each-mxf-profile.md).

# XDCAM RDD9 output requirements


MediaConvert supports the following combinations of encoding settings when your output **MXF profile** is **XDCAM RDD9**. 

In this table, read down the rows to find the **Resolution** that you want. Then read across to find a valid combination of **Bitrate**, **Frame rate**, **Interlace mode**, **GOP size**, and **Codec profile**.

# Audio settings requirements for different MXF profiles
Audio output requirements

This table shows the requirements for how you set up your output audio tracks in your AWS Elemental MediaConvert job. The requirements are different for each MXF profile that you choose.

**Note**  
If you don't include any audio tracks in your output, then you must make sure that there is no audio at all in your job settings.   
In your JSON job specification, this means removing the `AudioDescriptions` object entirely.
In the MediaConvert console, this means that you must delete the **Audio 1** tab that MediaConvert inserts for you by default. Delete it by choosing it, and then choosing **Remove audio** in the upper right of the **Encoding settings** section.


| MXF profile | Output audio requirements | 
| --- | --- | 
|  Generic OP1a  |  Audio codec: Uncompressed WAV Number of channels per track: 1, 2, 4, 6, or 8  | 
|  Sony XAVC (RDD32)  |   Audio codec: Uncompressed WAV  Number of channels per track: 1  Number of tracks per output: Any even number from 2 through 16  Bit depth: 24 bits  Sample rate: 48 kHz  | 
| Sony XDCAM |  Audio codec: Uncompressed WAV Number of channels per track: 1 Number of tracks per output: Any even number from 2 through 16, or no audio at all Bit depth: 16 bits or 24 bits; you must choose the same value for all audio tracks in the output Sample rate: 48 kHz  | 
| XDCAM RDD9 |  Audio codec: Uncompressed WAV Number of channels per track: 1 Number of tracks per output: 2, 4, or 8 Bit depth: 16 bits or 24 bits; you must choose the same value for all audio tracks in the output Sample rate: 48 kHz  | 
| D10 (SMPTE-386) |  Audio codec: Uncompressed WAV Number of channels per track: 4 or 8 Number of tracks per output: 1, or no audio at all Bit depth: 16 bits or 24 bits; you must choose the same value for all audio tracks in the output Sample rate: 48 kHz  | 

# Video passthrough
Video passthroughVideo passthrough

MediaConvert added support for video passthrough for HEVC (H.265) input videos.Video passthrough

MediaConvert added support for video passthrough for AVC input videos.Video passthrough

MediaConvert now supports video passthrough for I-frame only input videos.

MediaConvert supports video passthrough for **AVC (H.264)**, **HEVC (H.265)**, and **I-frame only** inputs. For AVC and HEVC inputs, you can create an output with any supported container type. For I-frame only inputs, you can create MXF or QuickTime outputs. Use video passthrough to repackage one or more inputs without any video encoding.

When you use video passthrough, you can repackage your input video but you cannot re-encode or otherwise modify the video essence.

## Using video passthrough


The following sections describe how to configure your job settings with Video passthrough. 

### MediaConvert console


To specify Video passthrough using the MediaConvert console:

1. Open the [Create job](https://console.aws.amazon.com/mediaconvert/home#/jobs/create) page in the MediaConvert console.

1. On the **Create job** page, provide transcode instructions and job settings. For more information, see [Tutorial: Configuring job settings](setting-up-a-job.md). 

1. Specify one or more supported inputs. If you specify multiple inputs, each of your input's encoding attributes must exactly match, including video codec, frame size, profile, frame rate, and color space.

1. Next to **Output groups**, select **Add** .

1. Keep **File group** selected and choose **Select**. 

1. In the **Output settings**, choose a **Container**. Note: If your input has an I-frame only video codec, you must choose **QuickTime** or **MXF**.

1. In **Encoding** settings, under **Video codec**, choose **Passthrough**.

### API, SDK, or AWS Command Line Interface (AWS CLI)


The following is an excerpt of a job settings JSON that specifies Video passthrough for an Apple ProRes workflow with two inputs:

```
{
  "Settings": {
    "Inputs": [
      {
        "FileInput": "s3://amzn-s3-demo-bucket/prores.mov"

If you specify multiple inputs, each of your input's encoding attributes must exactly match, including video codec, frame size, profile, frame rate, and color space.

**Input clips**  
(Optional) MediaConvert supports input clipping for I-frame only video codecs when you use video passthrough. These include Apple ProRes, AVC-Intra, DV/DVCPRO, JPEG 2000 (J2K), and VC-3.

**Output container**  
When you create MXF outputs from I-frame only inputs, MediaConvert supports the following input frame rates: 23.976, 24, 25, 29.97, 50, 59.94, 60

**Frame rate**  
You must keep the default setting, **Follow source**. You cannot specify a different output frame rate than your input. 

**Audio codec**  
(Optional) MediaConvert supports audio encoding when you use video passthrough. 

**Dolby Digital passthrough**  
(Optional) MediaConvert supports **Dolby Digital passthrough** when you use video passthrough.   
If you specify multiple inputs, each of your input's Dolby Digital streams must have identical encoding attributes. 

**Captions**  
(Optional) MediaConvert supports sidecar formats when you use video passthrough.

# AAC output reference tables
AAC output reference tablesAAC audio codec

We added a section that lists the supported combinations of coding mode, profile, sampling rate, and bitrate for the AAC codec.

This topic covers AAC audio codec support and lists the supported combinations of coding mode, profile, sampling rate, and bitrate.

This section explains how to set the following four properties of the AAC audio codec:
+ **Profile**
+ **Coding mode**
+ **Sample rate**
+ **Bitrate**

The settings that you choose for **Profile**, **Coding mode**, **Sample rate**, and **Bitrate** are limited by the AAC codec. The following procedure shows how to configure a supported combination of settings.

**Choosing AAC audio codec settings**

1. Choose a **Profile**.

1. Choose a **Coding mode** that is valid with that profile. The **Coding mode** determines the number of audio channels and the audio channel layout metadata. 

1. Choose a **Sample rate** that is valid for that combination of profile and coding mode.

1. Choose a **Bitrate** that falls within the range that is supported for that sample rate.

## CBR Bitrate control mode


AWS Elemental MediaConvert supports the following combinations of AAC settings when your output **Bitrate control mode** is **CBR**. 

To use this table, choose a profile from the **Profile** column. Then read across to find a valid combination of **Coding mode**, **Sample rate**, and **Bitrate**:

# Creating audio-only outputs
Creating audio-only outputsCreate audio-only outputs in a DASH container

MediaConvert added support for audio-only DASH outputsCreate audio-only outputs

Learn how to create MediaConvert outputs that contain only audio, without video.

You can use AWS Elemental MediaConvert to create outputs that contain only audio, without video. With audio-only outputs, MediaConvert supports a more limited number of codec and container combinations for input and output files.

The restrictions and procedures in this chapter apply to outputs that don't have video in the container. This includes the following:
+ Outputs in **File** output groups that don't have video included
+ Streaming **HLS** output groups that contain only audio outputs
+ Streaming **DASH** output groups that contain only audio outputs

When you set up streaming output packages that contain audio, video, and captions, you create separate outputs for each element inside the output package. These are not audio-only outputs as described in this chapter. For more information about setting up streaming outputs, see [Creating outputs in ABR streaming output groups](setting-up-a-job.md#create-outputs-in-abr-streaming-output-groups).

You set up an audio-only output in the same way that you set up an output that contains video, except that you don't include video or captions. 

MediaConvert generates the following files for audio-only outputs:
+ **File** output groups: One separate audio-only file for each output.
+ **HLS** output groups: A single rendition in the ABR stack for each output.
+ **DASH ISO** output groups: A single rendition in the ABR stack for each output.

**Note**  
For AAC streaming outputs, the initial segment is longer in duration than the others. This is because, with AAC, the initial segment must contain silent AAC pre-roll samples before the audible part of the segment. MediaConvert accounts for these extra samples in the timestamps, so the audio plays back correctly. 

**To create an audio-only output (console)**

1. To confirm that MediaConvert supports your input files, consult the input table in [Supported output formats for audio-only workflows](audio-only-output.md).

1. Set up your job as described in [Tutorial: Configuring job settings](setting-up-a-job.md), but with the following differences:
   + Remove the **Video** tab in the **Encoding settings** section of your output.
   + Choose a supported output container and audio codec from the output table in [Supported output formats for audio-only workflows](audio-only-output.md).
   + Include only one group of audio settings per output. That is, don't choose **Add audio** to create an **Audio 2** tab under **Encoding settings**.

1. If your outputs are in an **HLS** output group, choose a container for the audio-only output.

   Under **Output settings**, in the **Audio** section, for **Container for audio-only output**, choose **MPEG-2 Transport Stream** to create a file in an MPEG2-TS container. Keep the default value **Automatic** to create a raw audio-only file with no container.

**To create an audio-only output (API, SDK, and AWS CLI)**

1. To confirm that MediaConvert supports your input files, consult the input table in [Supported output formats for audio-only workflows](audio-only-output.md).

1. Set up your JSON job specification. Either manually edit your JSON file, or use the console to generate it as follows:

   1. Follow the previous procedure for the console.

   1. In the **Job** pane on the left, under **Job settings**, choose **Show job JSON**.

   The JSON job specification for audio-only jobs differs from standard jobs as follows:
   + Exclude each instance of `VideoDescription` and its children from the `Outputs` portion of your job JSON.
   + For each output, include only one child group of audio settings under `AudioDescriptions`.
   + For audio-only outputs in an **HLS** output group, specify a container for the audio-only output. Under `Outputs`, `OutputSettings`, `HlsSettings` include the property `HlsAudioOnlyContainer`. Set it to `M2TS` to create a file in an MPEG2-TS container. Set it to `AUTOMATIC` to create a raw audio-only file with no container. `AUTOMATIC` is the default behavior.

# Captions reference tables
Captions reference tables

MediaConvert supports a wide range of captions conversion workflows. But you can't convert every supported input captions format to every supported output captions format. Each video container supports a subset of all possible captions types. Furthermore, MediaConvert supports a subset of all transformations theoretically allowed within the input and output video container type.

For information about how to set up captions in your input, see [Setting up input captions](including-captions.md).

For information about how to set up captions in your output, see [Setting up captions in outputs](set-up-captions-in-outputs.md).

To look up whether MediaConvert supports your captions workflow, choose the topic from the following list that corresponds to your input captions. Find the table that corresponds to your video output container. Then find the row for your input captions. Check the supported output captions format column to see the available output captions formats.
+ If your primary MediaConvert input contains your captions, see [Supported input captions, within video containers](captions-support-tables-by-container-type.md).
+ If your captions are in a separate file, which you specify in your input captions selector, see [Supported input captions, within sidecar files](sidecar-captions-support-tables-by-container-type.md).

# Supported input captions, within video containers
New supported captions formats

Updated reference tables to reflect new support for the following captions formats. On input: SMI, SCTE-20. On output: SCTE-20 \$1 embedded, Embedded \$1 SCTE-20, SMI.New supported captions format

Updated reference tables to reflect new captions support. IMSC sidecar output captions now available in **CMAF**, **DASH ISO**, and **File group** output groups. You can generate these from the following input captions formats: Ancillary, Embedded, IMSC, Teletext, TTML, SCC, SCTE-20, SMI, SRT, and STL.New supported input captions format: SMPTE-TT

Updated reference tables reflect new captions support. MediaConvert now supports SMPTE-TT captions as input.

To look up whether MediaConvert supports your captions workflow, choose the topic from the following list that corresponds to your video output container. Then find the row that corresponds to your input captions container and format. Check the supported output captions format column to see the available output captions formats.

## Supported captions in QuickTime output container
QuickTime output container

The following table lists supported output captions formats for this output container. Use when your input captions are in the same container or stream as your video. This table is sorted by the input captions container and input captions format. 

If your input captions are in a sidecar format, see [Sidecar captions supported in QuickTime output container](sidecar-captions-support-tables-by-container-type.md#sidecar-quicktime-output-container). *Sidecar captions* are captions that you provide as a separate input file from your video.

## Sidecar captions supported with File output groups
Sidecar captions in File output groups

The following table lists standalone sidecar output captions formats that MediaConvert supports with outputs in the **File** output group. *Sidecar* captions are captions that are in a separate file from your video. 

If your input captions are in a sidecar format, see [Sidecar captions supported with File output groups](sidecar-captions-support-tables-by-container-type.md#sidecar-captions-supported-as-standalone-file-in-output). *Sidecar captions* are captions that you provide as a separate input file from your video. 

When you set up these output captions in your job, choose **No container** (`RAW`) for **Container**, under **Output settings**. In your JSON job specification, specify it this way:

```
 {
            "ContainerSettings": {
              "Container": "RAW"
            },
```

**Note**  
You can create sidecar captions outputs only as part of a job that also generates a video output.
