Parameters
Name Description
data array

Optional. Data for populating the Message object.
↳ width_pixels int

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.
↳ height_pixels int

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.
↳ frame_rate float

Required. 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.
↳ bitrate_bps int

Required. The video bitrate in bits per second. The minimum value is 1,000. The maximum value is 800,000,000.
