user16374: When I type the following ffmpeg command:
```
ffmpeg -i input.mov -c:v prores -profile:v 3 -c:a pcm_s16le -bsf:v prores_metadata=bt709 output.mov
I have the following error:

Unknown bitstream filter prores_metadata

However this bitstream filter is documented here: https://ffmpeg.org/ffmpeg-bitstream-filters.html#prores_005fmetadata
My ffmpeg version is 4.1 downloaded from Homebrew on macOS 10.13.
Any idea what is going wrong?

user1871: The bitstream filter was added after 4.1.
