FYI - I have two videos one will open and one will not.
200MB, Length 4min, 1280x960, Total bitrate 6100 kps, 60fps
3.7GB, Length 21:25, 1920x1080, Bitrate 25321k, 60fps
The larger video give an error after a minute: "Error was: cannot open video file."
Both have same codec H265 -MPEG-4 AVC part 10 avc1, both GoPros.
Window 7 64 Bit, 32gb ram, ssd scratch disks and media disks
Is anyone else finding such limits?
