ffmpeg will only insert the conversion if required, it the original
source has the correct pixel format, no unnecessary conversion is
inserted.

Furthermore, yes, all movs will be fine with yuv420p, but in higher
profiles than main, you may want to use other pixel formats, assuming
your players support them.
