问题
I have made a video for my app and upload this App Preview onto iTunes Connect. However, it cannot be saved. I already used the latest Safari on OS X 10.10 and tried many times.
Anyone succeed with upload an App Preview?
回答1:
Try restarting Safari. Worked for me after 5 failed attempts with different files.
回答2:
Had the same problem that iTunes Connect would not save the video.
Turns out the screen recordings I made with QuickTime off of an iPad/iPhone via Lightning cable had a frame rate that was too high (~58fps). The Apple docs say that max 30fps are allowed.
I changed the framerate with ffmpeg (installed via Homebrew):
ffmpeg -i input.mov -r 30 output.mov
Bonus: If you want to strip the audio from the recording, add -an as a parameter.
ffmpeg -i input.mov -an -r 30 output.mov
