This is pretty easy to accomplish, and you can do it with a command like:

ffmpeg -i infile.mp4 -pix_fmt yuv420p -codec copy -map 0 outfile.mp4

instead of `-codec copy` in the above, you may want to change it to
explicitly convert to h264
(which I know works) as some newer videos are h265 (which i don't think
does on the pi)
so something like:

ffmpeg -i infile.mp4 -vcodec h264 -pix_fmt yuv420p -codec copy -map 0
outfile.mp4

which will copy all the rest of the streams without conversion, and only
reconvert the video

Take care!!
