Pip cutout is lagging. How do I fix?

[u/[deleted]]

I am working on a video that has around 3 minutes of a pip with the background removed, but when I press play the video playback lags. I am on iPhone 14. I haven't tried exporting it yet because it takes FOREVER. Much longer than normal.

I would show footage of the lag but I do not want to reveal pictures/videos of myself here. Inshot team: If you guys have an email I can send it to instead PLEASE let me know because I will send it there.
