Description

Slow Fast Slow is an app for manipulating the speed of videos you shoot on your iPhone. It works especially well with slo-mo videos. Use the intuitive interactive timeline to slow down or speed up your videos. Additionally, you can add pitch control, as well as clip reversal.

• Import videos from your Photo Library.
• 240 fps videos (iPhone 6 and 6 Plus) can be slowed down to 1/16 speed, which is twice as slow as the built in camera app.
• Pitch Control: Retain the correct audio pitch even when the video is sped up or slowed down.
• Backwards playback.
• Add and remove points to adjust the timeline.
• Export videos in the original ratio or square.
• Requires iOS 10.

Does its job but...

The infrastructure is maddening. I was surprised to learn that it was developed by a design firm because some functions are completely impractical. Before I even start on a new set of videos I have to erase a bunch of videos that I already have no use for. Also, it asks you to select videos, but first you have to remember to deselect previous videos, and then asks you to select the videos again before you can work on them. It adds much more work than needed. Not a problem if you’re just using the app once in a while, but frustrating if you’re using it everyday for multiple videos.

Great Free App That Truly Works Well

I’ve tried other apps to speed up my videos and they stop at 4x speed increase, lose my HD video quality, and just don’t work that well. This one is a really good app — it’s easy to import and export videos and allows for multiple points you can put in a video to speed up/slow down certain points. This one allows up to 8x speed increase of the imported video, so for faster ones you’ll have to save and import the video again but that’s easy enough. I haven’t seen any ads yet either beyond a quick message when you open the app for first time after downloading then any time after that just a quick small message that you can click on to go to their website or continue with what you’re doing instead of annoying ads that become a nuisance. Definitely recommend this app though! It works great so my videos still have the HD quality and a nice smooth high speed playback after saving the edited video that I then import into iMovie and this works great! I use this as iMovie will only increase a video up to 2x original speed.

Hidden gem

This app does not have the exposure it deserves. It doesnt try to scam you into unlocking or paying for extra features. It does great for slow and fast. Yeah, theres limits but by exporting and re editing, you can surpass the limit. Its easy to use and you can speed up and slow down in one clip. Most other apps i have come across or either or and not both. Honestly, i dont know why this app has more exposure, this is great! Its crashed on me maybe once out for 25-30 uses. Yeah the rendering might take a bit but thats acceptable for the amount it lets you edit per video.

The only thing i would say is a con is that its a bit hard to fine tune on a small phone screen but other than that, i recommend 100%
