把mov的视频转成movie maker能认的格式，用啥软件啊？

Posted 2023-04-16

我用相机拍的视频，是mov格式，想转换后，用movie maker编辑一下，（我这不能用别的编辑视频）要求转换后清楚的，请介绍个好用的转换软件。我用格式工厂转换时，只能转开头一帧画面，显示转换了100%，其实没转成。有会用的，也可指点一下，谢谢！

iOS 录制视频MOV格式转MP4

使用UIImagePickerController系统控制器录制视频时，默认生成的格式是MOV,如果要转成MP4格式的，我们需要使用AVAssetExportSession;

支持转换的视频质量：低，中，高，640*480，720p,1080p等

如下代码片段转换

- (void)mov2mp4:(NSURL *)movUrl
{
    AVURLAsset *avAsset = [AVURLAsset URLAssetWithURL:movUrl options:nil];
    NSArray *compatiblePresets = [AVAssetExportSession exportPresetsCompatibleWithAsset:avAsset];
    /**
     AVAssetExportPresetMediumQuality 表示视频的转换质量，
     */
    if ([compatiblePresets containsObject:AVAssetExportPresetMediumQuality]) {
        AVAssetExportSession *exportSession = [[AVAssetExportSession alloc] initWithAsset:avAsset presetName:AVAssetExportPresetMediumQuality];
        
        //转换完成保存的文件路径
        NSString * resultPath = [NSHomeDirectory() stringByAppendingFormat:@"/Documents/output-%@.mp4",@"cvt"];
        
        exportSession.outputURL = [NSURL fileURLWithPath:resultPath];
        
        //要转换的格式，这里使用 MP4
        exportSession.outputFileType = AVFileTypeMPEG4;
        
        //转换的数据是否对网络使用优化
        exportSession.shouldOptimizeForNetworkUse = YES;
        
        //异步处理开始转换
        [exportSession exportAsynchronouslyWithCompletionHandler:^(void)
         
         {
             //转换状态监控
             switch (exportSession.status) {
                 case AVAssetExportSessionStatusUnknown:
                     NSLog(@"AVAssetExportSessionStatusUnknown");
                     break;
                     
                 case AVAssetExportSessionStatusWaiting:
                     NSLog(@"AVAssetExportSessionStatusWaiting");
                     break;
                     
                 case AVAssetExportSessionStatusExporting:
                     NSLog(@"AVAssetExportSessionStatusExporting");
                     break;
                 case AVAssetExportSessionStatusFailed:
                     NSLog(@"AVAssetExportSessionStatusFailed");  
                     break;
                 case AVAssetExportSessionStatusCancelled:
                     NSLog(@"AVAssetExportSessionStatusCancelled");
                     break;
                  
                 case AVAssetExportSessionStatusCompleted:
                 {
                     //转换完成
                     NSLog(@"AVAssetExportSessionStatusCompleted");
                     
                     //测试使用，保存在手机相册里面
                     ALAssetsLibrary *assetLibrary = [[ALAssetsLibrary alloc] init];
                     [assetLibrary writeVideoAtPathToSavedPhotosAlbum:exportSession.outputURL completionBlock:^(NSURL *assetURL, NSError *error){
                         if (error) {
                             NSLog(@"%@",error);
                         }
                     }];
                     break;
                 }
             }
             
         }];  
        
    }  

}
