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 

Sanyo E1 Video camera

Most months I come across a new video variation.  One of the latest is a Sanyo E1.  The video is 'standard' MP4 but the physical recording is non standard.  The customer had spent a few years trying to get the video recovered with no success.  The problem is that the moov atom is both fragmented, and out of sequence, and interleaved with the start of the mdat atom.  No program that just does data carving could ever recover this type of file.  Once the correct sequence was determined recovery was possible.  The initial attempts found video, but no sound, but eventually this was resolved. 

CnW Recovery V4.99 now supports recovery for many such videos, though a few tweaks are still required for longer files.

Website URL

My new GoPro Recovery program is working well, but sales are currently limited.  Most sales appear to be UK based, and USA, where the big market is, is still limited.  One reason I feel for this is because the website goprorecover.co.uk  is a .uk website.  I have now tried a new website, www.recovergopro.com  in the hope that having set my Google preference for world wide coverage, I will get more USA hits.  Time will tell.

An area I am also working on is to try and ensure the two websites are different enough in content so as not be classed as duplicate, even though they have started from the same base.
