well i have officially had my first card error, and have exausted many options thus far trying to get my video back. the file structure is there, but after attempting to hex-edit the proper header/footer to try to get (at least) VLC to play the file, i have had no luck so far. the card, a MxR with transcend 16g, seperated the long recording into 4 18 min segments. i can get the first 18, and last 18, but not the middle ones. i have looked for and used a few of the demo programs to try to recover and most of them at least recognize that there is a file that needs help and the demo claims to be able to fix it (for a charge)

While i try to weed out the crap freeware and adware based garbage, what programs have you guys used to fix the mp4 files with some success, either PC or MAC i have both, i just dont want to download any more crap programs and delete them. theres gotta be a decent free one out there somewhere. please help :)
 
tried that one and also filesalvage for mac. no luck... im looking for a mp4 repairer specifically, accessing the file isint as much of a problem.
 
So far, treasured for mac is the only thing that has been able to view the entire missing clips straight from the mp4 files.

clip browser software for the PC will let me view the files but not export, so at this point, i might be going ghetto and using a screen recorder/audio recorder to attempt to salvage the footage unless i can find a better way by the end of the day
 
Hi,

ffmpeg might also be worth a try. Somtimes it does really good job on recovering damaged files.

At first I would try something like

ffmpeg -i damaged.mp4 -vcodec copy -acodec copy salvaged.m2t (I am choosing m2t as transport streams seem to be more fault tolerant than mp4. Data will only be wrapped in another container, so there will be no quality loss.)

If this is failing I would try:

ffmpeg -i damaged.mp4 -vcodec dnxhd -acodec pcm_s16le -b 185Mb salvaged.mov (This will convert video to a dnxhd compressed mov file.)
 
Hey friend, it might occur due to problem in header file or when there is problem with video codec. In order to rescue MP4 files and to make it playable again you may try to restore it from backup option. It might works for you.
However, if you this method rfails to you don't have proper backup then you may try MP4 video recovery software. Its eminent video recovery features and latest scanning algorithm rescue all your corrupted or lost mp4 videos.

A very long time ago I paid a fee to use Aero Quartet / Treasured to recover deleted xdcam-ex files. Got almost all of the data back, at a cost.

I notice the original poster here was using SDHC media instead of SxS cards - I will say I've never had an SxS card failure, save the human error of formatting the card and needing the data back. SxS cards cost significantly more than SDHC cards, but they also feature far better error correction and other magic to prevent problems like this.

I take it that the XDCAM Browser doesn't recognize the clip as being present?
