Capture 60fps on iOS to reduce motion blur

Question

I need to reduce motion blur in my video, so I tried every sessionPreset on AVCaptureSession to get 60fps video capture but none of them seem to work. I found a few old threads that mention the 1280 preset would work on iOS 5, but I had no success with any preset on iOS 10 (iPhone 6).

It just fails when I try to configure activeVideoMin/MaxFrameDuration to 60fps.

The queried format also says it only supports a range between 2 to 30fps.

Is there really no way to capture 60fps (or reduce video motion blur) on iOS 10?

Answer 1

Iphone 6 and 6 plus has tow device format. one for 1080p30 and another for 1080p60. When you set AVCaptureSessionPresetHigh it uses 1080p30.

To record vide with 60fps, iterate through AVCaptureDevice Formats, find the format you want and then set AVCaptureDevice **setActiveFormat** property instead of AVCaptureSession setSessionPreset .
