it's a suuuper simple script:
ffmpeg.exe -f u8 -ac 2 -ar 13824 -i file.raw -f rawvideo -pixel_format rgb555 -video_size 32x18 -framerate 24 -i file.raw -vf scale=w=1280:h=720:flags=neighbor file.mp4
fun thing is that if you changed the final width and height you can even make the video 4k if you wanted to
also, if you want to change the source video size then you'd have to also change the audio options to sync otherwise the vid and aud won't be in sync anymore
