Hi, Finlayson. Thank you very much for your software. You saved me and my last video and you permitted me to edit and post it on youtube. Great!

I would like to add a little contribution about the recovery process, based on my recent experience.

To edit these kind of videos, I always use AviDemux, with which I only make cuts of segments without any other effects. Every cut is strictly made across the key frames, so that I can save the resultant video as a copy, without any recoding. While editing the repaired video I noticed that, once uploaded to youtube, the image transitions were "disturbed". For example, when a video segment called "A" is attached to a video segment called "B", the transition is like:

...AAABABBB...

instead of:

...AAAABBBB....

This is probably due to a imprecise indexing of the key frames within the repaired file (I suppose). In any case I fixed this issue by recoding the video before the edit process, forcing a keyframe every second (keyint=25). In this way I was able to cut my video with a quite good precision, respecting the (new) keyframes. This is the complete h264 setting that I used for recoding, configured to minimize the quality loss:

• cabac=1 / ref=16 / deblock=1:-2:-2 / analyse=0x3:0x133 / me=umh / subme=10 / psy=1 / psy_rd=1.00:0.25 / mixed_ref=1 / me_range=24 / chroma_me=1 / trellis=2 / 8x8dct=1 / cqm=0 / deadzone=6,6 / fast_pskip=1 / chroma_qp_offset=-4 / threads=6 / lookahead_threads=1 / sliced_threads=0 / nr=0 / decimate=0 / interlaced=0 / bluray_compat=0 / constrained_intra=0 / bframes=8 / b_pyramid=2 / b_adapt=2 / b_bias=0 / direct=3 / weightb=1 / open_gop=0 / weightp=2 / keyint=25 / keyint_min=13 / scenecut=40 / intra_refresh=0 / rc_lookahead=25 / rc=crf / mbtree=1 / crf=18.0 / qcomp=0.80 / qpmin=0 / qpmax=69 / qpstep=4 / ip_ratio=1.10 / aq=1:0.50
  

After that I was able to cut, edit and upload the resultant video, and youtube has not detected flaws anymore.

Hope this can help.
Thanks again.

Thanks so much or this! (some years after you posted it!).

I just pecr a week trying every piece of repair software there is. Then I came across this post and it worked right away.

Brilliant!

I just used your code to repair my damaged file. Thank you very much!!!!

Just to clarify - For the software that I wrote (referenced above), I also have pre-built application binaries for both Windows and Mac OS X, so if you're on one of those systems, you don't need to compile anything; just download and run a program (in a command window).  My program - "djifix" - is actually a lot easier to use than "recover_mp4_to_h264" (although they probably do similar things).

Once again, for those who may be interested: http://live555.com/drones/DJI-Phantom-2-Vision+-video-fix/

Too funny, I just sent you an email in regards to how awesome your program is in comparison to the other options available.
I validate this software long before any other "expensive" tool found in the first 10 pages of google search results.

Thank you so much for writing this piece of software and sharing it! I had a piece of video that was greatly anticipated by some graduating seniors and I thought it was lost forever. Your software, and instructions, worked like a charm. Can't thank you enough for making this available!

Thanks, Ross. djifix still works fine for the phantom 3 corrupt videos, even if the thread is old. But you still need something to convert the h264 to mp4 afterwards, so thanks tony. mp4muxer was the answer for that.

This is AMAZING! I can't believe how many times I've just thrown away files because I thought they were unsalvageable. Can't wait to use this. THANKS

Hi Ross,
I hope you are still around. I have a file that I really would like to repair but this doesn't seem to work under Windows 10 64 bit, or I might be doing something wrong. Can you help me? Thank you!

Edit: I have figured out how to do it. Thank you again for the good advice!

Had a video from my P3S I couldn't play, google brought me here and your program worked like a charm! Thanks Ross!!!

For MAC users how are you opening the djifix.dms file to get to djifix?

I use Erelive Data Recovery to Recover Deleted Videos in SD, you can get notice from https://www.erelive.com/recover-deleted-videos-from-canon/ . Good luck.

It might do, but it will not recover a DJI video file that was not finalised. The issue is not 'deleted' file recovery, it is one of correctly terminating the file.

@Wachtberger
At 2017-10-20 you said you did figured out how to run the 32bit program on 64bit win10. Would be a help if you tell us how.

Just rename the file to remove the .dms This is something safari adds for some reason

Drowned my P4A in Saltwater! Hit lightpost while tracking boat and BANG KERPLUNK! Battery poped out before diving in. Video did not finalize. Im 63 and not a computer wizard. Whats the simplest way to fix file in order to view. It was a beautuful shoot, as whale watching boat entered harbour! Thanks in advance! Rudy in NB

Thanks for valuable infomation,and there is easier way to recover lost video.Using data recovery program is a efficient and reliable way,since the program has powerful method to scan your device and can list them on program windows,you can preview and choose the target files to recover.

No, it will not work becuase it is not a deleted file, it is an MPEG file that has not been finalised. The best solution is given in Post #3.

I hate to be that cynical guy, but has anyone verified this? I’ve been burnt too many times before

Yes, it works just fine.
