 Summary of the bug:
 When I try to crop e.g. the top right corner of a video into a png, the
 output is corrupted. I have to stay 10 ish pixels away from the right edge
 to make it work.

 How to reproduce:
 I am trying on a 1280x720 .mov prores video, I don't know if it matters.

 {{{
 crop=w=20:h=20:x=1260:y=0:exact=1:keep_aspect=0
 }}}

 Results in corrupted PNGs, whereas the following works just fine:

 {{{
 crop=w=20:h=20:x=1250:y=0:exact=1:keep_aspect=0
 }}}

 in stderr I see nothing that indicates there was an error
