Now I want to get 3 video from this multiple Tracks. First video is combine with 1,4,7 track and Second video is combine with 2,5,8 track and Third video is combine with 3,6,9 track and and Audio track is common for this three video.</p> <p>I want to do this using following code.</p> <pre><code> AVPlayerItem* playerItem = [AVPlayerItem playerItemWithURL:[NSURL fileURLWithPath:urlSubItem.path]]; NSLog(@"%@",playerItem); NSArray* arrTracks = [playerItem.asset tracksWithMediaType:AVMediaTypeVideo]; NSLog(@"%@",arrTracks); NSArray* arrTracksText = [playerItem.asset tracksWithMediaType:AVMediaTypeText]; NSArray* arrTracksAudio = [playerItem.asset tracksWithMediaType:AVMediaTypeAudio]; NSLog(@"%@:%@",arrTracks,arrTracksAudio); for (int i=0; i&lt;3; i++) { AVMutableComposition* mixComposition = [AVMutableComposition composition]; AVMutableCompositionTrack *compositionCommentaryTrack = [mixComposition addMutableTrackWithMediaType:AVMediaTypeAudio preferredTrackID:kCMPersistentTrackID_Invalid]; [compositionCommentaryTrack insertTimeRange:CMTimeRangeMake(kCMTimeZero, playerItem.asset.duration) ofTrack:[[playerItem.asset tracksWithMediaType:AVMediaTypeAudio] objectAtIndex:0] atTime:kCMTimeZero error:nil]; CMTime currentTime = kCMTimeZero; for (int k=0;k&lt;[arrTracks count];k++) { NSLog(@"%d",k%3); if(k%3==i){ AVAssetTrack* trackCombineVideo = [arrTracks objectAtIndex:k]; AVMutableCompositionTrack *compositionVideoTrack = [mixComposition addMutableTrackWithMediaType:AVMediaTypeVideo preferredTrackID:kCMPersistentTrackID_Invalid]; NSError* errors; [compositionVideoTrack insertTimeRange:CMTimeRangeMake(currentTime, trackCombineVideo.timeRange.duration) ofTrack:[arrTracks objectAtIndex:k] atTime:currentTime error:&amp;errors]; if (errors) { NSLog(@"wait error:%@",errors); } currentTime = trackCombineVideo.timeRange.duration; } } AVAssetExportSession* _assetExport = [[AVAssetExportSession alloc] initWithAsset:mixComposition presetName:AVAssetExportPresetPassthrough]; _assetExport.outputFileType = @"com.apple.quicktime-movie"; NSLog(@"file type %@",_assetExport.outputFileType); _assetExport.outputURL = exportUrl // Document Directory Path; _assetExport.shouldOptimizeForNetworkUse = YES; </code></pre> <p>Using this code 3 separate video is create but each video have a 3 different track. Now, my question is how to create video with only one track ?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
