I've been having a lot of problems converting 23.98 FPS to 24 FPS. Specs: H.264 1280 x 720, it's in a .m4v wrapper. There's no audio. I tried using Compressor to convert it to Pro Res 422, but it fails each time. I also have tried converting it to HDV 1080i60, and it works except halfway through it just stops and freezes on one frame (and it's the same frame each time). Help! What am I doing wrong? Am I forgetting about something basic here? I feel like an idiot. Thanks everyone in advance.
