Hi John,
Song-length videos are best loaded as a clip in Session View. The files Simpler can handle depends on the resolution and the length of the video files.
That said, I’d expect the end frame not to default back to 2880 and Videosync to not crash. Maybe you can send me the video file you’re having issues with via email?
I also have a not yet released alternative for you that should make Simpler handle song-length files. I can get you up-and-running with that via email as well.
Best,
Hidde
