 Summary of the bug:
 I'm overlaying transparant PNGs over another video which I'm upscaling.
 Somehow I seem to be losing frames.

 How to reproduce:
 {{{
 % ffmpeg  -i big_buck_bunny_1080p_h264.mov -i frame%05d.png
 -filter_complex "[0:v] scale=3840:2160[bbb];[bbb][1:v] overlay[out]" -map
 "[out]" test.mp4
