Is it possible to customise Krita’s FFMPEG render? As Windows 10's native media players still don't support the YUV444p pixel format, which seems to be FFMPEG's default format, is it possible for a Krita user to easily (or relatively easily) reconfigure Krita’s FFMPEG command line to specify, say, YUV420p?

While downloading the VLC Media Player is, of course, an option, as is ‘simply’ collecting Krita’s PNG file render output and running FFMPEG against them manually, life would be a lot easier if Krita’s render workflow was seamless at this point.

While I don’t mind tinkering around at the command prompt, it’s not ideal for people who’ve grown up in a GUI environment. So. Any helpful suggestions or workarounds, anybody?
As per the code, you need to set the profile in Video Export Options to high and Krita will force the pixel format to yuv420p. There also appears to be a Custom Options field where you could fill -pix_fmt yuv420p but if the profile is incompatible (like high422), ffmpeg will bail out.
