most of the assets are mp4s, made in other applications and many by other contributors.
there is a root menu with 3 sections, each with a number of videos in them. section 1 has 5 videos, section 2 has 8 and section 3 has 26. the total filesize is about 2gb. the total duration is about 170 minutes, which i think might be one of the problems.
they are all mp4 videos (but different frame sizes-another problem?)
the codecs are all either h264 AAC or MPEG-4 AAC.
