Bad for prerecorded video – Duet Camera - Dual Recording Review

Got this to try to make a TikTok duet with a video I didn’t get on TikTok. It won’t let you play the videos side by side and adjust them, so you have to export it to see what they look like side by side. After exporting maybe 5 times, the app no longer works. I click “create duet”, it appears to make progress for a second, then nothing. The app freezes. Waste of $0.99.
