`bitRate`	integer Format: int64	False	The bit rate of the audio track, in bits per second.
`channels`	integer	False	The number of audio channels in the audio track.
`frameRate`	FrameRate	False	The frame rate of the video or audio track, expressed as a fraction with numerator and denominator values.
`languageCode`	string	False	The language code of the audio track, in three character ISO 639-3 format.
`sampleRate`	integer	False	The sample rate of the audio track.

CodecMetadata

Codec-specific parameters parsed from the video essence headers.This information provides detailed technical specifications about how the video was encoded, including profile settings, resolution details, and color space information that can help you understand the source video characteristics and make informed encoding decisions.

Property	Type	Required	Description
`bitDepth`	integer	False	The number of bits used per color component in the video essence such as 8, 10, or 12 bits. Standard range (SDR) video typically uses 8-bit, while 10-bit is common for high dynamic range (HDR).
`chromaSubsampling`	string	False	The chroma subsampling format used in the video encoding, such as "4:2:0" or "4:4:4". This describes how color information is sampled relative to brightness information. Different subsampling ratios affect video quality and file size, with "4:4:4" providing the highest color fidelity and "4:2:0" being most common for standard video.
`codedFrameRate`	FrameRate	False	The frame rate of the video or audio track, expressed as a fraction with numerator and denominator values.
`colorPrimaries`	ColorPrimaries	False	The color space primaries of the video track, defining the red, green, and blue color coordinates used for the video. This information helps ensure accurate color reproduction during playback and transcoding.
`height`	integer	False	The height in pixels as coded by the codec. This represents the actual encoded video height as specified in the video stream headers.
`level`	string	False	The codec level or tier that specifies the maximum processing requirements and capabilities. Levels define constraints such as maximum bit rate, frame rate, and resolution.
`matrixCoefficients`	MatrixCoefficients	False	The color space matrix coefficients of the video track, defining how RGB color values are converted to and from YUV color space. This affects color accuracy during encoding and decoding processes.
`profile`	string	False	The codec profile used to encode the video. Profiles define specific feature sets and capabilities within a codec standard. For example, H.264 profiles include Baseline, Main, and High, each supporting different encoding features and complexity levels.
`scanType`	string	False	The scanning method specified in the video essence, indicating whether the video uses progressive or interlaced scanning.
`transferCharacteristics`	TransferCharacteristics	False	The color space transfer characteristics of the video track, defining the relationship between linear light values and the encoded signal values. This affects brightness and contrast reproduction.
`width`	integer	False	The width in pixels as coded by the codec. This represents the actual encoded video width as specified in the video stream headers.

ColorPrimaries

The color space primaries of the video track, defining the red, green, and blue color coordinates used for the video. This information helps ensure accurate color reproduction during playback and transcoding.
