 - Remux MKV video to MP4 without re-encoding audio or video streams:

 `ffmpeg -i {{input_video}}.mkv -codec copy {{output_video}}.mp4`
+
+- Convert MP4 video to VP9 codec. For the best quality, use a CRF value (recommended range 15-35) and -b:video MUST be 0:
+
+`ffmpeg -i {{input_video}}.mp4 -codec:video libvpx-vp9 -crf {{30}} -b:video 0 -codec:audio libopus -vbr on -threads {{number_of_threads}} {{output_video}}.webm`
