Hi,

 

I have a 16Gb MOV file from OnLocation CS5.5 for Mac that has been corrupted. The program froze and then crashed mid record and the file is now unusable. Is there any way that the file can be repaired or the video footage recovered?

 

Thanks,

 

Larry

    What's the codec?

    If it's DV it should be salvageable by Media Salvage. It might actually be H.264.

     

    The issue with these formats is that the sample table is written last. This tells the media player where each frame and audio sample is located, so without this it can't find any of the data. You can't copy across the sample table for another movie so it must be rebuilt somehow.

    No, if it hasn't found any frames in the first 6.5 GB then it's not going to find any. What this means is that the codec you selected from the dropdown is not the codec stored in the file.

     

    When it locates a frame it marks it as recovered and then skips ahead, meaning it's normally a lot quicker. When it can't find the frames it scans every byte of the file which is why it's been going for so long.
