command line – Ffmpeg: how to get information about rawvideo encoder

For example When i type ffmpeg -h encoder=ffv1 i have information about supported pixel formats (Supported pixel formats: yuv420p yuva420p yuva422p yuv444p etc) and settings (ffv1 encoder AVOptions: -slicecrc E..V……. Protect slices with CRCs (default auto) -coder E..V……. Coder type (from -2 to 2) etc) of this encoder.

But when i type rawvideo instead of ffv1 i have this:

Encoder rawvideo [raw video]: General capabilities: dr1 threads Threading capabilities: frame

and that is all. no pixel formats, no setting. does anyone know how to fix it?
