Perfect
This app is the best for what it does, better than any paid app. It has so many more features than other apps like itself, like fast and slow motion in certain spots and its also able to reverse it. Definitely the best!MattC450
So good
this is so amazing good job :)attmatt
Not bad...
The app seems to do what it sets out to do nicely, a simple way to manipulate footage speed for short clips, but I have a couple of issues that affect my usage,
1) limited bezier handles, (4, with two anchored to the start and end) I would like to be able to manipulate my footage speed more than the app allows. Or at least not have the start and end anchored to two of these handles.
2) I would like some information about what speed the handles are at, is the footage at 1/4 speed 1/2 speed etc etc.
I've given 4 stars as it does what it sets out to do well, but it could do a bit more :)Show lesstbr_blackpool
Ingenious
This app is no longer restricted to working with square video. Although I can't see how to record in anything but square mode it's now easy to import video from the camera roll which makes Slow Fast Slow a great place to edit the speed of video you recorded earlier.
The interface is simple and ingenious and it's easy to change the speed of a clip multiple times over its duration—something the built-in app can't do and iMovie can achieve only with quite a lot of cutting. You can't trim or remove portions of video but for quick effects it's great.Show lessSternhammer
Room For Improvement
I really like the app but unfortunately discovered a bug straight away, selecting an empty video square causes the app to crash.
It's a shame you can't import your own videos shot separately and it would also be nice to have the option to add more than the two speed markers, not bad though.Winger15mk
