Slow Fast Slow - Control the Speed of Your Videos

Unable to export video

I will gladly pay some money for this free app!

this app does exactly what I needed for my videos, unlike all of the other apps that I tried. Very glad that i found this one.

It’s so good it edits my video so smoothly ❤️

The app is not working. They are also charging me for an app called Unlock timeline, which I have no idea what is that. I'm reporting to Apple right now.

This app is horrible

Great for videos that you want to have two or more parts slo-mo. However, two features that would be nice would be landscape mode and the ability to zoom in on a section to fine-tune which frames you want slow and which fast.

Whenever I Finish editing and save it to my camera roll it doesn’t make a difference fix this and I’ll rate it higher

Simple, easy to use, and lets you export for free!!! (Btw your product looks great)

I was looking for something like this a phone video quick editing app using key frames to change the speed on some parts of the video. And yes this app can do it. Make sure you record videos on your iphone with 60fps to have better slowmo quality. The only downside is audio gets affected as well. I hope the developer adds an audio layer on the timeline in the future to incorporate your own bg audio. Well it's not a pro video editing software though lol :) Other than that great app highly recommened!
