I change the JPGs that I used for start images. Basically, FFMPEG (that does the video) can take a bit to decode, so the jpg was able to show something rather than a blank black screen. I change to AVIF to get an accurate count of images without too much issues. ;)

However, I also fixed a bug where the last scene for Dee played at certain points during that chapter. This was caused by an if that should have been an elif. That has been changed, and now that should play as normal.
