this is a bit of a mess. masks are completely off.

i add some code to remove background - and save out videos. the amount of effort to clean up videos is quite steep - will be a blessing when EmoPortraits drops new video dataset.

i make some call to just crop every video frame to head - then resize back to 512. I add a flag. - i think this makes most sense - as they say they do crop / warp - and they're training resolution is 256x256 and 512 x512

000009 i rip out background too.
