Honestly don’t know. I was multi-tasking at the time. I opened the app, selected the video from my photos and hit the process button. Took about a minute to process. I tried to share it to Primal from the app but it wouldn’t work so I saved it back to photos, returned to Primal and uploaded from there. Pretty smooth, but the quality is not great. I’m sure it was user error.

Unfortunately iOS is where I'm the least helpful 😅
But I'm sure it's possible to do better.
I have seen other iOS users recommend this app.

720p is a good middle ground for file size and quality.
This guy has me muted so I'm only replying for others, but don't use 720p for most videos. That's way too high to load reliably for anything that isn't very still.
360p or less for maximum reliability, around 480 or 540p for a good balance.
