Performance problems on 1TB iPad Pro M4

Hi, I have been using Rush on my first gen iPad Pro, and found performance was not great, with really choppy playback at times on fairly simple projects. Upgrading to the newest 1TB M4 iPad Pro, I expected these issues to be completely eliminated but was disappointed to find that basically on every transition across clips, Rush will go through about 20 seconds or so of playback where the framerate is just atrocious, super choppy, almost unusable. Is anyone else seeing this? This can't really be a hardware problem can it?

    Hi @alanshi,
    Thanks for the note. Bad performance problems, eh? That's not fun. What kind of media are you editing? Are iOS and Rush updated? Please provide more information so we can help you.

     

    Thanks,
    Kevin

    Hi @Kevin-Monahan, thank you so much for the prompt reply. I am a super casual Rush user. I am basically editting GoPro footage (usually 2.7k 60fps) from vacations, and do little more than string together a few clips, pictures, and music with light transitions and maybe tweaking the speed to highlight some portions. Clip lengths are generally anywhere from 10-25 seconds each, with the entire project less than 5 minutes.

     

    Yup, using the latest iOS and Rush (these were just updated when I received the brand new M4).

     

    I only have a few projects (half a dozen or so), and every single one has several segments where the playback seems to drop to maybe 1 frame per second or less (audio is still running fine, and the video eventually catches up and returns to normal).

    Oh, I can help you with that. Which specs is the camera capable of shooting? Can you shoot in 2K 8-bit 4:2:0? That should work, for example.


    Hi @Kevin-Monahan , I believe my GoPro will produce 2.7K 10-bit 4:2:0 H.264 files (sometimes I also record at 4K 10-bit 4:2:0). What are the maximum specs that you think will be supported for video files before transcoding on a desktop is required ahead of using Rush on an iPad?
