SloPro app allows for true 60fps HD shooting on iPhone 4S

Can toggle slow-motion live or in editing

A new, free app from the App Store has promised users a long-desired feature for retaining high quality HD even when using slow motion for things like acrobatic stunts. SloPro says it can use the camera in a variety of recent iPhone, iPad and iPod Touch models, but the 60 frames per second recording that is its main selling point remains exclusive to the iPhone 4S for now. A $2 "pro upgrade" allows users to save the raw footage to iTunes for third-party editing.

The program, when used on an iPhone 4S, records at 60fps natively and thus users have the option of either switching to slow motion "on the fly" (live while recording) or later on in the simple editing mode (see video, below). The editor makes it easy to pinpoint the start and stop points of the slow-motion segment, as well as trim clips and save them to a variety of social networks.

SloPro avoids the problem encountered by apps that record in HD video at 30fps, which is the slowing down the frame rate below 30fps results in "jerky" slow motion. SloPro offers three settings of slow motion built into the app, the slowest still being above the 29.97fps required for smooth motion in NTSC video. While the program will work as a camera, editor and uploader on non-4S iOS devices, the smooth slow motion function will not be available, as the shooting rate is limited to 30fps.
