Takes a video asset and reverses it, puts it in a AVMutableComposition and exports it as a .mov file.

The exported file becomes available in iTunes under File Sharing ( [iOS Device]/Apps/ReverseClip).

##How to implement? Just copy the folder “RCToolbox” to your project.

Import the class “RCToolbox.h” in your class.

    RCFileHandler *filehandler = [[RCToolbox sharedToolbox] fileHandler];
    AVURLAsset *myAsset = [filehandler getAssetURLFromBundleWithFileName:@“[asset]”];
    [self preExportForImageSequence:myAsset];

 -(void) preExportForImageSequence:(AVURLAsset *)_asset
  {
 	    RCComposer *compositionTool = [[RCToolbox sharedToolbox] compositionTool];
    [compositionTool addToCompositionWithAsset:(AVURLAsset*)_asset timeRangeSpeed:kTimeRangeSlowMotion inSeconds:0.0 outSeconds:2.0 isForImageSequence:YES speed:kTimeRangeSlowMotion];
}

In this case you will probably use CMTimeZero for inSeconds and asset.duration for outSeconds.

##Tweak it To change the width and height of the clip, change the constants in RCImageSequencer.m

You might want to comment out NSLog(@"Percentage done: %f",percentageDone); in the same class.

##How does it work?
