MXF video

MXF is a video encapsulation program, and as in many programs, the video is stored sequentially on the camera memory chip.  I have a problem with an exFAT memory chip froma Sony PXW-X70 camera XAVC which had been partially formatted.  All fragmentation information was lost.

The solution was to add a new wizard function to CnW.  This scans the memory chip and isolates key types of cluster, headers, indexes, and video data and trailer.  Once found, these XAVC video files are reconstructed in the correct logical order and video will play.

This is another growing example of video that cannot be recovered by standard data carving methods.  Unfortunately many companies may claim to process such files because they are probably tested by writing files sequentially to a memory chip, and saying that recovery is possible.  True, but this is not the way the camera writes it's data
