Solution

  • You can set the maximum duration using the property maxRecordedDuration of your AVCaptureMovieFileOutput settings.

    Here's an example.

    self.movieFileOutput = [[AVCaptureMovieFileOutput alloc]init];

Float64 maximumVideoLength = 60; //Whatever value you wish to set as the maximum, in seconds
int32_t prefferedTimeScale = 30 //Frames per second

CMTime maxDuration = CMTimeMakeWithSeconds(maximumVideoLength, preferredTimescale_;

self.movieFileOutput.maxRecordedDuration = maxDuration;

self.movieFileOutput.minFreeDiskSpaceLimit = 1024*1024;

  if(self.captureSession canAddOutput:self.movieFileOutput){
     [self.captureSession addOutput:self.movieFileOutput];

  }

    I hope this answers your question
