I have an mp4 file that was taken with a XDCAM (SD card) 1.65GB
The camcorder was switched off inadvertently while the camera was busy recording. As a result, the file is corrupt.
1. The XDCAM will not playback the file.
2. Quicktime also refuses. Most other players crash or act strange too. (VLC; Media player; GOM etc)
3. The file can be loaded into Premiere Pro and scrubbed (I can see and hear the footage), but exporting the file causes unholy errors and system failure.
(Note: If the file is copied from the original SD card to another device and then loaded into Premiere Pro, it says the file is corrupt and won't load.)
4. I tried to convert the file to another format with AVS media converter, but the program says the file is corrupt. (Says something like, "Unknown file format".)
I opened the file in a Hex Editor, and a large proportion of the start just has zeros (compared to a healthy mp4 file recorded on the same cam).
I also tried to get some more info on the file with Media Info, but nothing is displayed (besides the file size and location).
Someone suggested transplanting the header from a healthy file into the mp4... anyone have any suggestions on how to go about this?
This matter is particularly frustrating since I can scrub the file and I literally just need 25 seconds of footage, but I can't export it!
This is what a healthy mp4's info from the XDCAM looks like:
