SloPro Cranks iPhone 4S Camera To 60FPS For True Slow-Motion Video



SloPro is an app that magically makes the iPhone’s video camera shoot at 60 frames per second. And while the developers are being coy and refusing to reveal the mechanics behind it, the product does indeed let you double the camera’s frame rate, and therefore let you shoot some excellent slow-motion footage.

Even if you ask with a “pretty please,” you’ll get nothing from the SloPro people other than this mysterious statement:

There is a bit of a trick to it that nobody else has figured out even though they’ve tried.

But the app is free (with an in-app purchase to upgrade to “Pro”), so you can try it for yourself.

And it works. Shoot something, and when you play it back it will run in half-speed slo-mo. You can edit the clips to flip between different playback speeds, giving you that neat kind of bullet-time effect which looks so good in sports and other action movies.

You can share your movies via Twitter and Facebook, but if you want to save them to the camera roll, export the raw 60fps footage, remove the watermark or e-mail videos, then you’ll have to spring for the $2 upgrade. As this app is a first-rate video-camera even without the 60fps effect, that’s a bargain right there.

One note: On first launch on my iPad 3, the app told me that true 60fps recording is iPhone 4S-only, but can still use the app and see the video slowed down the old-fashioned way. The results are still rather nice.

SloPro is available now in the App Store.

    That’s a cool video.  My kids and I spent about 2 hours recording
    ourselves on the tramp with the free version.  The free version does
    allow a slick YouTube upload option as well that the author didn’t

    Damn.. I just bought this app thinking because the iPhone 4s records 1080p video, that this app shoots in slo mo at that resolution. It doesn’t! Its only 720p…  my Canon 7D does that…i don’t need video in 720p 60 fps. I was hoping this would be a little higher resolution at least. No where on the App Store or in this article does it tell you that its NOT 1080p… please update this as some people might not want to pay for an app that’s only limited to 720p

    @Stephen_t_james. Good call out, I was thinking about getting it, but now its a no-go

    Oh Gee .. no 1080p?!   Guys, I’ve been around small video cams for a while that shoot a variety of sports .. and I cannot think of any of the GoPro type cams that shoot both 1080 x 60 fps. Not one. (and none seem to have a built-in phone..)  It seems that all these Red Bull types can make some highly produced, and certainly well viewed videos – in 720 x 60 fps.

    It’s like – $2 .. and people still whine that it will not turn a cell phone into a 4K Red One..  Jeez!
