Sony's film and television cameras generally use the MXF file structure. In some extreme cases (such as power failure), RSV files will be generated. How should we deal with this situation? Let's take a look at today's case.
Fault file: 12.51G RSV file
Symptoms:
After the power failure, only a file with the extension rsv is generated. It can be played with the player but there is no sound, and the duration is only 8 seconds. Combined with the length of the file, this duration must be wrong!
Failure analysis:
After dealing with Sony cameras for a long time, the processing flow of the Sony camera management program is probably reversed:
1 audio and video capture (memory)--->2 temporary file RSV generation (memory card)--->3 metafile generation (memory card or memory)--->4 regenerate MXF/MP4 file (memory card)- -->5 Delete the RSV file
It can be seen that RSV is the original audio and video file. This type only collects the most original picture and sound according to the corresponding file structure such as (mxf or mp4). At this time, the file cannot be played because there is no meta file. At this time, the player cannot perform decoding operations.
The reason why this file can be played for 8 seconds is because the player uses the forced decoding function, so the duration is abnormal and the audio code cannot be obtained. Now it can be judged that there is a problem in the second step, and the RSV has capacity. At this time, what we need to do is to generate the metafile in the third step, that is, to repair the RSV file. One more thing, there is another situation where the RSV file is 0 bytes. The solution in this case is to use the video scanning module of the CHS Zero One video recovery program to scan it first. For the specific method, refer to the case we published before.
Troubleshooting:
STEP1: Run the advanced version of CHS Zero One Video Recovery Program, click "Video Repair" to switch to the repair interface. Currently, the repair function supports repairing damaged video files such as mp4, mov, 3gp, and mxf.
Click "Sample File" to add the sample file, which is required to be the normal file generated by the camera;
Click "Damaged File" to open the damaged 12.51G file. We changed the name of this file for convenience and added bad instead of the original name. The extension mxf was modified by the customer. If there are multiple files to be repaired, click "Batch Damaged Files" to add multiple damaged files.
STEP2: Click "Repair" to repair and wait for completion. It can be seen that the program has successfully parsed out the camera brand, duration, speed and other parameters.
STEP3:修复完成，查看修复结果。可以看到修复后修复级别为四星，代表修复效果很完美；时长是45分37秒这个也和客户提供的拍摄时间大致相同；右侧预览可以试用播放。
由于这个是外景多机位拍摄，这个机位更多的是音频的采集，所以对音频要求高，经过查看修复后的视频文件，音、视频都完全正常，至次修复工作完成。
