# VideoBackgroundRemovalGreenScreenInput

## Fields

- `output_codec` · enum · optional — Output encoding. vp9 (the default) yields a single webm video with an alpha channel; h264 yields two files (the RGB video and an alpha matte) and is recommended for better RGB quality. Accepts `vp9`, `h264`. Defaults to `"vp9"`.
- `spill_suppression_strength` · number · optional — How strongly green cast is removed from the kept subject. Raise it when green spots remain, lower it when colours shift on the subject. Between 0 and 1. Defaults to `0.8`.
- `video_url` · url · required — URL of the source video, shot against a green screen.
