Help with MP4 file! please

posted in File Types

Ok, I made a vid with a friend and i used my phone to record it and accidently deleted it from my Samsung G600 phone, =.=

and ive used about 10 programs to try recover it and some of them did recover the dleted video,but all the recovered files cant be played by quicktime and vlc doesnt recognize them
when i use quicktime to open it says:
Error -2048: Couldn’t open the file Video-0035.mp4 because it is not a file that QuickTime understands.

i tried using converters such as 3gp and imtoo mov but they both dont recognize the file and classify it as (Unknown)

anyone know what i can do to make it be able to make it into a playable video again?

thx

The file header’s probably gone. See my post here:
http://www.moviecodec.com/topics/46097p1.html
I know less about MP4 files than I do about AVI’s though. I do believe the header is at the start of the file because I can preview incomplete MP4 file downloads with QuickTime. (The reason why I used to think it wasn’t was because I usually need the footer for MOV files, which MP4 files are derived from - but then again maybe the header can be anywhere in the file? MOOV atom or whatever it’s called).
The steps I outlined may or may not work. I’d suggest calling a data recovery company if the videos are really important. And no matter what you do, don’t overwrite the media.
gspot 2.70 would be able to analyze the file if it was recognized as an MP4. If not, you may have to artificially create an MP4 header like in my other posts (I really don’t know if it will work with MP4 files - because there may be restrictions that keep files of incorrect length from playing - plus I can’t think of a repair/parsing/analysis tool for MP4 files of the caliber of VirtualDub (which is for AVI’s). Just remember to use another cell phone or memory card or whatever to create sample videos lest you overwrite your deleted videos!
I strongly suggest asking the people at the doom9.org forums, because they have a LOT of experience with MPEG-4. Perhaps one of the coding wizards could write up a program to salvage raw chunks of video straight from the media without any header data. reply

Hi folks

Had a similar problem with my mpeg4 and jpeg files on my SD card giving error 2048 etc

It turned out that one file (I’d already copied!) gave a different error 2002 I think, something about Bad Public Movie Atom... Everything I recorded after that file was corrupt and still won’t open, BUT

I deleted that file and everything I record now seems ok...

Fingers crossed! reply

Hi there, came to notice your post on the corrupted mp4 video file. Would you please shed some light for my corrupted mp4 video file too? Just one file (13.3MB) which I took during my trip to Thailand from a mobile phone. I have tried all my best in searching up google for many solutions thus it didn’t help. I guess my best bet is to add the mp4 header which I have completely no idea where to copy and paste it into.
I hope you can help me or point me in the right direction on fixing this.

Million of thanks..... Appreciate your kind help.

Regards,
Vincent reply

I had the same problem with a movie that I downloaded. Quicktime gave me the 2002 error, and other programs froze and were not able to play it.

I changed the extension of the file to .MKV and voilá ! (I’ve lost the first minutes of the movie, though).

Best,

Juan reply

I have the same problem becuase when i accidentally deleted my video from my vacation and when i recovered them they would not open it said file could not open. reply

Maybe you should take a try of this data recovery software tool, use the free tiral version first. It says it is able to recover video files including formats such as MP4, MOV, AVI etc deleted or lost.

Note: before they are recovered, never attempt to put more files to the device as overwritten data is unrecoverable. reply

Hi, sandeepdeepu.

Your recovered MP4 video files maybe corrupted. Recuva can help recover files you deleted but the quality is not guaranteed. Find some more good recovery software from this site: digital camera recovery. And then take a try. Good luck. reply
