Recover corrupted video after phone reboot during recording
Hello,
was wondering if someone could help in recovering a corrupted video recorded on my Nokia n900. The phone did a random reboot during recording and now I'm stuck with a video file that is not playable(tried mpc, vlc ...). I tried recovering using some tools i found on the internet but none of them worked. From what I could gather, the video is lacking the moov segment at the end of the file, but I have no idea how to restore it or if it is even possible. The file is a mp4 video with the following header information: ftyp: mp42 isom:3gp6 I'd be grateful for any help (links to relevant info? maybe someone had to do this in the past?). Thanks. |

Have you tried to play with mplayer?
You could try to fix with mencoder: Code:
mencoder -forceidx -oac copy -ovc copy /tmp/src.mp4 -o /tmp/dst.avi |
Re: Recover corrupted video after phone reboot during recording
maybe use a commandline video splitter that will split the file without needing to display it first. That way maybe you end up with a playable and a non playable part.

Re: Recover corrupted video after phone reboot during recording
I had to do (almost) exactly same thing, some time ago. I was able to recover video, although, results were not very satisfying - audio/video sync was PITA to repair (more precisely, frames per second on video), and somehow, keyframes were messed up - i don't know how it's possible in already recorder stream, but it looked like all keyframes stacked up together, so, periodically, You've had perfect picture for a few seconds, going gradually worse and worse... to the point of awful quality, then, PONG! awesome quality again, going gradually worse and worse... Everything over the same period of time (7-8 seconds), rinse and repeat.
Finding a tool was also a PITA - to my knowledge, there is only one freeware tool capable of doing so, and, to make things worse, company producing it made it payware starting from some version number, and carefully deleted prior version from almost everywhere. Newer version doesn't have any better functionality, and it's perfectly legal to use older, freeware version, but - no idea how they achieved that - links for downloading it doesn't seem to exist *anywhere*. fortunately, I was able to get in contact with someone who used it during times of freeware, and wrote on his blog about it - he still had program on his hard drive, and was kind enough to send it to me. --- So, here You have it: Videorepair 1.5 I don't remember usage instructions, but, it was quite straightforward. After all, you can always check their website - new payware version uses same procedure, IIRC. /Estel |

Re: Recover corrupted video after phone reboot during recording
No, it doesn't (just downloaded it myself). try downloading it another time - I think you might have started downloading it, while I was still uploading (and as a result, got only part of file).
As for searching anywhere else, of course, You may, but I really doubt You'll be able to. /Estel |

My iPhone 4 shut off exactly when saving the movie after recording it - low battery and very cold outside. I tried many ways to recover it, none worked until I tried your suggestion! Great job sharing this!! |
Re: Recover corrupted video after phone reboot during recording
I'm glad it helped you - I remember going through real PITA when trying to find solution. BTW, hosting I've used is quite OK, but, nevertheless, may disappear one day - as program developers made quite huge effort to make sure, that freeware version disappear from every download page (despite it being perfectly legal), I suggest mirroring it somewhere.
Quite a life saver, for videos recorder by N900 (or other devices, using same format). /Estel |
Re: Recover corrupted video after phone reboot during recording
Hello:),
Its quite difficult but can be repaired easily:confused:. First, stop experimenting with that video file of your Nokia, it may worsen the situation. I would suggest you to use Video Repair utility, that could fix your corrupt video file on your Nokia. even if the video is severely corrupt it easily fixes the file. one important point is this tool does not edit or harm the source file. it just extracts the contents from it and saves it in a new file:). I feel, this tool would be the best solution for your worries about how to fix corrupted mpeg video files? first, you can go for trial version, then use purchase the software.Just give a try, Hope it works fine. Best of luck.:cool: |
Re: Recover corrupted video after phone reboot during recording
Why purchase, if there is a freeware version with *same* capabilities, available legally? I've posted it, few pages back.

@Estel: I would think this is pure advertisement, nothing more, nothing less!
Really thought about reporting, but you already mentioned it years ago :), so i did not. |

Re: Recover corrupted video after phone reboot during recording
closed source windows freeware, so what do you expect? At least, they have really written it themselves, not just ripped some FOSS project (sadly, there is no FOSS project able to recover our videos in such case).
Anyway, wine *is* native. It wouldn't be native, if you would had to emulate something (like, cpu - but of course, I got what you meant, anyway, so mentioning it just for the record). /Estel |
Re: Recover corrupted video after phone reboot during recording
There are closed source apps for Linux - e.g. smartsvn ;)

Re: Recover corrupted video after phone reboot during recording
I tried to download the software from the link in this thread but its no longer available on the server. Does anybody have it that wouldn't mind re-posting? I have this problem and would really love to save this video that got corrupted when my phone locked up while it was saving. I know this thread is old but I have to try!!
