Optional arguments:¶
iv_adaptivequantization TYPE /AWS1/MDLH265ADAPTIVEQUANTIZ00 /AWS1/MDLH265ADAPTIVEQUANTIZ00¶

There are three types of adaptive quantization: spatial, temporal, and flicker. Flicker is the only type that you can customize. We recommend that you set the field to Auto. For more information about all the options, see the topic about video adaptive quantization in the MediaLive user guide.

The Temporal Filter reduces bandwidth by removing imperceptible details in the content. It combines perceptual filtering and motion compensated temporal filtering (MCTF). It operates independently of the compression level.
The Bandwidth Reduction filter is a perceptual filter located within the encoding loop. It adapts to the current compression level to filter imperceptible signals. This filter works only when the resolution is 1080p or lower.

TreeblockSize¶
Select the tree block size used for encoding. If you enter "auto", the encoder will pick the best size. If you are setting up the picture as a tile, you must set this to 32x32. In all other configurations, you typically enter "auto".
Accessible with the following methods¶
| Method | Description |
|---|---|
GET_TREEBLOCKSIZE() |
Getter for TREEBLOCKSIZE, with configurable default |
ASK_TREEBLOCKSIZE() |
Getter for TREEBLOCKSIZE w/ exceptions if field has no value |
HAS_TREEBLOCKSIZE() |
Determine if TREEBLOCKSIZE has a value |
MinQp¶
Sets the minimum QP. If you aren't familiar with quantization adjustment, leave the field empty. MediaLive will apply an appropriate value.
Accessible with the following methods¶
| Method | Description |
|---|---|
GET_MINQP() |
Getter for MINQP, with configurable default |
ASK_MINQP() |
Getter for MINQP w/ exceptions if field has no value |
HAS_MINQP() |
Determine if MINQP has a value |
Deblocking¶
Enable or disable the deblocking filter for this codec. The filter reduces blocking artifacts at block boundaries, which improves overall video quality. If the filter is disabled, visible block edges might appear in the output, especially at lower bitrates.
Accessible with the following methods¶
| Method | Description |
|---|---|
GET_DEBLOCKING() |
Getter for DEBLOCKING, with configurable default |
ASK_DEBLOCKING() |
Getter for DEBLOCKING w/ exceptions if field has no value |
HAS_DEBLOCKING() |
Determine if DEBLOCKING has a value |
GopBReference¶
Allows the encoder to use a B-Frame as a reference frame as well. ENABLED: B-frames will also serve as reference frames. DISABLED: B-frames won't be reference frames. Must be DISABLED if resolution is greater than 1080p or when using tiled hevc encoding.
Accessible with the following methods¶
| Method | Description |
|---|---|
GET_GOPBREFERENCE() |
Getter for GOPBREFERENCE, with configurable default |
ASK_GOPBREFERENCE() |
Getter for GOPBREFERENCE w/ exceptions if field has no value |
HAS_GOPBREFERENCE() |
Determine if GOPBREFERENCE has a value |
GopNumBFrames¶
Sets the number of B-frames between reference frames. Set to 2 if resolution is greater than 1080p or when using tiled hevc encoding.
Accessible with the following methods¶
| Method | Description |
|---|---|
GET_GOPNUMBFRAMES() |
Getter for GOPNUMBFRAMES, with configurable default |
ASK_GOPNUMBFRAMES() |
Getter for GOPNUMBFRAMES w/ exceptions if field has no value |
HAS_GOPNUMBFRAMES() |
Determine if GOPNUMBFRAMES has a value |
MinBitrate¶
Used for QVBR rate control mode only. Optional. Enter a minimum bitrate if you want to keep the output bitrate about a threshold, in order to prevent the downstream system from de-allocating network bandwidth for this output.
Accessible with the following methods¶
| Method | Description |
|---|---|
GET_MINBITRATE() |
Getter for MINBITRATE, with configurable default |
ASK_MINBITRATE() |
Getter for MINBITRATE w/ exceptions if field has no value |
HAS_MINBITRATE() |
Determine if MINBITRATE has a value |
SubgopLength¶
Sets the number of B-frames in each sub-GOP. FIXED: Use the value in Num B-frames. DYNAMIC: Optimizes the number of B-frames in each sub-GOP to improve visual quality. Must be FIXED if resolution is greater than 1080p or when using tiled hevc encoding.
Accessible with the following methods¶
| Method | Description |
|---|---|
GET_SUBGOPLENGTH() |
Getter for SUBGOPLENGTH, with configurable default |
ASK_SUBGOPLENGTH() |
Getter for SUBGOPLENGTH w/ exceptions if field has no value |
HAS_SUBGOPLENGTH() |
Determine if SUBGOPLENGTH has a value |
