I'm stumped. I've got a project full of 1080 29.97fps mp4 clips that previews and exports fine. A friend sent me a clip that I'd like to incorporate into my project. This clip has become problematic for me and nothing I do seems to help it live alongside the other clips. It's from a GoPro and it's a high-def, 2160, 60fps, hevc clip. VideoPad imports it fine and previews it with no problem. But, every attempt to export/build it to a 1080, 29.97fps output file just stops the build at that spot.
I've tried converting this clip to different resolutions--no help. To different fps--no help. Using h264 and av1--no help. Different formats like .mov, avi, wmv, etc. Everything seems to work fine except the VP export process. Without sending in the file, is it common to see a build conflict between the two clip types above? Lower-res 1080, 30fps, 464 and hi-res, 2160, 60fps, hevc? Thoughts?
