佳能相机，相机型号如：600D, 6D, 5D2, 5D3, 5DS, 5D4, 760D, 5D4, 6D2等EOS单反相机系列，正常录制的视频可能是MOV或者MP4, 如果相机在拍摄中遇到异常情况，电池没电，异常断电等，录制的视频不会是MOV或者MP4，而是DAT文件，文件无法打开，无法渲染，播放失败。
这种情况如进行简单修复，往往效果不理想，有产生掉帧，声音不同步，卡顿等问题。
针对于佳能全系列型号的机器所拍摄的.DAT. MOV. MP4的视频损坏，可以采取视频编码修复方法：对视频的编码进分析，确定编码版本，视音频编码类型，然后对损坏的视频进行完美修复，这样修复出来的能够正常播放，无卡顿，声音同步，可以用软件直接编辑的。如果相机断电、死机等没有产生文件的，或者文件是0字节的，要先用专业办法恢复出来数据再进行修复。
以下提供正常播放的佳能相机MOV视频信息供参考，可参考修复损坏文件：
