佳能相机MP4视频文件变小或打不开播放不了怎么修复

佳能MP4视频文件损坏打不开播放不了

遇到这样一个问题,视频是用佳能5D4录制的MP4格式视频素材 ,视频拍摄一切正常,拒回忆在相机上回放也没有任何问题,但是回来用读卡器导素材时却发现有一半素材是坏的,查看文件属性,大小有点不对劲,比正常视频文件小太多了。问题是这样的变小损坏的MP4视频文件是否还能够修复好?

通过MP4视频文件代码修复解决损坏问题

首先检查这些损坏的文件代码,文件头明显是错误的,文件尾不用看了,因为大小变小的,肯定是数据不全,这个问题只能从SD上来进行修复。如果SD卡还没有被二次使用进的,通过视频代码修复技术来进行修复处理,可以解决此类问题。

有必要在这里提醒:如发现文件损坏,千万要保留SD卡,不能轻易认为有文件在就可以直接修复好。

以为下佳能MP4视频文件的编码信息,供修复参考:
