Optimized proxy/media out of sync with audio on iOS

[asikuna]

I made a project on my desktop using Adobe Rush and it created the optimized proxy and uploaded it to the cloud like usual. Then I go on my iPad to try to edit the project and the video is out of sync with my audio and it seems that the audio is slightly slowed down because my voice is deeper. Along with the fact that after the visual ends, the audio keeps going, even though it's not stretched out any longer in the timeline. I'd like to think this is a frame rate issue but I'm not sure.

The video format is:

1920x1080

60 fps

.mp4 format

It happens to all my clips and they range between 18-32 GB in size and they're all about an hour long. I've contacted Adobe support about this issue MULTIPLE TIMES and none of them have been able to help me.

To clarify: this only happens on my iPad Pro after optimized media from my desktop has been uploaded to Creative Cloud and downloaded to my iPad. When I import directly to my iPad, it works flawlessly. The reason I can't just import from my iPad and go is because for one, it's a 32 GB file that I'd have to download to my iPad, then reupload. And second, I've already tried it and the video doesn't even show up in the camera roll for me to be able to import.

If someone can get to the bottom of this and help me out it would be greatly appreciated.

Hey Z!

This is really interesting, I'll be sure to take notes of your experience and communicate it to the appropriate team. This might be a little bit of a pain, but I may have a workaround. If you run your footage through Handbrake before importing it into Rush on your desktop, does the audio stay in sync when you switch to your iPad?

Is this screen-recorded footage? Your workflow sounds similar to some other gamers I know.

Let's get to the bottom of this! More than happy to hear your issue and find a permanent fix.

I was able to fix my issue by rerendering the footage to match the original settings through Adobe Media Encoder.
