I love this app. I've been using it for years with no problems. I took a small break from editing videos for a ahort while, however. And when I came back and used this again, it seems like there is now a flashing added to the video after it's been slowed down. It seems very subtle at first, but once I add some video filters for what I'm working on, it becomes significantly more notocable. I did spend money on this app, so I'd be very disappointed if I have to find a new way of slowing down video. But the flashing is not something I can deal with in the final product of my video. So I will find something new if that can't be fixed.

It’s really good!! ...but

Okay, i’d like to start off by saying this is a GREAT app. I like to make fan edits and it’s hard to find an app that ACTUALLY slows down the videos smoothly and this app does just that. My issue is that with the new update, the watermark is in the middle of the screen. I would pay for pro cause it’s quite cheap but I can’t due to phone issues. And with covid, the U.S. Cellular store is closed. I really don’t want the watermark there, no offense. With how it was before, I could just crop it out cause it was near the bottom. But now it’s splat down in the middle of my videos. Another thing is that you can’t save the videos without it just being black. Like when I try to save the video when finished, it doesn’t save. It just ends up being a black screen. It was never much of an inconvenience for me cause I could just screen record my video but it is kind of a hassle. It would be easier if the videos just saved. But if someone is reading this and looking to get the app, i’d recommend you pay for pro. I think in my situation, 4 stars is a generous rating.

Few requests

Hi i really hope the developers see this, so this is a really good app but I really wish it would go back to how it was before where you could add multiple speeds and please add more slower I make fan edits and when I try out 1000fps it’s not smooth but rather more choppy I’d like it to be more smoother eg how slomo is like on ae please bring the old SloPro back and change how it turns the quality down otherwise it’s a great app but please add more smoother slower options bring the normal option back make 1000FPS slower and without the choppy ness on how it moves the clips just slow it down like 0.25 no clip changes just slow yknow what I mean please make it look like how it did before and if possible please add settings to male twixtor edits and possibly make it more like ae AND PLEASE KEEP IT FREE THE ONLY REASON THIS APP IS GOOD IS CUZ ITS FREE
