Many errors and no way of re-editing once spending a credit
I bought the package of credits and bought more than I needed, which I ended up needing them all. Overall, it was okay, but several photos it made some really weird changes, such as completely changing the faces halfway through the video and some odd errors with hands and action. I had to re-do several videos many times, eating up the credits, without any way of resubmitting the same photo or editing it. Overall, I would have chosen a different tool as most of my photos and credit usage was completely unusable.
