Videos aren't saving properly ?? – Video Speed Editor - Slow down and accelerate your video Review

I downloaded this app & purchased it to keep one of my videos at full length. At first, I was having trouble saving it & when it finally did save, the only thing that actually worked was the music I had added. The video feed was black. ?? Ease of use is great, but I'm extremely disappointed that this app doesn't even work. Makes me think those reviews are fake. I'd be satisfied if I could get my clips saved properly, but for now..2 stars is all I'm willing to give & that is because I'm being generous. Now I'm tasked with finding out how to get in contact with someone to see if I can figure it out or get my money back. Yay. ?
