- `vbr` (numeric): Average video bitrate in KBit/s
- `fps` (numeric): Frame rate
- `dynamic_range` (string): The dynamic range of the video
- `audio_channels` (numeric): The number of audio channels
- `stretched_ratio` (float): `width:height` of the video's pixels, if not square
- `vcodec` (string): Name of the video codec in use

- `res`: Video resolution, calculated as the smallest dimension.
- `fps`: Framerate of video
- `hdr`: The dynamic range of the video (`DV` > `HDR12` > `HDR10+` > `HDR10` > `HLG` > `SDR`)
- `channels`: The number of audio channels
- `tbr`: Total average bitrate in KBit/s
- `vbr`: Average video bitrate in KBit/s
