Properties
The video bitrate in bits per second. The minimum value is 1,000. The maximum value is 480,000,000.
The target video frame rate in frames per second (FPS). Must be less than or equal to 120. Will default to the input frame rate if larger than the input frame rate. The API will generate an output FPS that is divisible by the input FPS, and smaller or equal to the target FPS. See Calculating frame rate for more information.
Select the GOP size based on the specified duration. The default is 3s. Note that gopDuration must be less than or equal to #SegmentSettings, and #SegmentSettings must be divisible by gopDuration.
Select the GOP size based on the specified frame count. Must be greater than zero.
The height of the video in pixels. Must be an even integer. When not specified, the height is adjusted to match the specified width and input aspect ratio. If both are omitted, the input height is used. For portrait videos that contain horizontal ASR and rotation metadata, provide the height, in pixels, per the horizontal ASR. The API calculates the width per the horizontal ASR. The API detects any rotation metadata and swaps the requested height and width for the output.
Pixel format to use. The default is yuv420p. Supported pixel formats: - yuv420p pixel format - yuv422p pixel format - yuv444p pixel format - yuv420p10 10-bit HDR pixel format - yuv422p10 10-bit HDR pixel format - yuv444p10 10-bit HDR pixel format - yuv420p12 12-bit HDR pixel format - yuv422p12 12-bit HDR pixel format - yuv444p12 12-bit HDR pixel format
Enforces the specified codec profile. The following profiles are supported: * profile0 (default) * profile1 * profile2 * profile3 The available options are WebM-compatible. Note that certain values for this field may cause the transcoder to override other fields you set in the Vp9CodecSettings message.
Specify the rate_control_mode. The default is vbr. Supported rate control modes: - vbr - variable bitrate
The width of the video in pixels. Must be an even integer. When not specified, the width is adjusted to match the specified height and input aspect ratio. If both are omitted, the input width is used. For portrait videos that contain horizontal ASR and rotation metadata, provide the width, in pixels, per the horizontal ASR. The API calculates the height per the horizontal ASR. The API detects any rotation metadata and swaps the requested height and width for the output.
