I've got 5 BIG MP4 files from a gopro camera. Each one is 3.9 GB (because the camera is polite and automatically splits the video into sub-4GB chunks)
I'm trying to load them into AE CS6. When I open them, I don't get any errors - but most of the video clips load OK, while the first one doesn't.
The one that doesn't load shows up in the Project tab as a 0x0 video, with a gray preview. The others correctly show up as a 4096x2160 11.98FPS H264 video, and I can scroll through them without issue.
What is really strange is that other apps can play ALL of the videos without issue - VLC, Quicktime, etc. So it isn't just a bad file.
So, is there some corruption that would keep that one video from loading? A bad EXIF tag modification? Some sort of AE cache that thinks that one file has no video track (or a 0x0 video) track?
I'd love to recover it without data loss.
It probably has some invalid stream flag which could be fixed with a quick pass-through transcode in an ffmpeg-based tool like Handbrake or MPEGStreamclip...
I did basically the same - dumped it through MPEGStreamclip and reduced the frame rate at the same time. So, was able to get around it.
