I've been working to improve the quality of the FMV movies in the game. I actually had them upscaled to 4k but the game only accepts 768x432 videos. I was able to make them look a little cleaner, and interpolate them to run at 60fps. This batch of videos will replace the old ones (make a backup of your movies folder, and then drag this one over and replace all the old files). This includes my Avengers themed main menu background video.
In other words this is a "remaster" of sorts for the videos, but it's still stuck at a low resolution unfortunately. Nonetheless I think it's better than the originals, so enjoy.https://drive.google.com/open?id=1FpqlXk12H65snSJZBAg7Zl2KvcZ9n45k
