Huge Avi file corrupted

[Nawaffles]

Hello
Recently, I accidentally deleted a video that I needed from the recycle bin. I used recuva to retrieve the video. However the video is now missing its index block and I can't edit it in any editing software. Also, I can't go forward or go to a part of the video in windows media player. I need help repairing this avi file.
Video specs:
1920x1080
Recorded at 60 fps.
The file is around 31 Gigabytes.
It was recorded with fraps.

Thanks!

Try ffmpeg:

"c:\path\to\ffmpeg.exe" -i "input file" -codec copy "output file"

If that fails, try to re-encode the file with VirtualDub. If that fails (and you are desperate), more suggestions are found here.

In the future, enable the Fraps "split movie every 4 GB" option. This will limit your losses in case of file corruption.

I downloaded ffmpeg. However, I don't know what to do. What do I do with that code?

Type (or paste) it into a command line interpreter -- ie, dos box. Be sure to change the ffmpeg path to where it is on your computer.

My avi is on my desktop. It is called 000078. I don't understand. How do I know where the ffmpeg path is?

if it's missing the mov atoms it's also probably nothing but garbage inside the file. once deleted, sectors of the file are re-used by windows and no longer contain the video. the recovery program may have gotten all the original sectors re-assembled but they don't contain your video anymore.

To easily change your path is go the folder where the file is and click on left click shift,hold it down and right click your mouse and choose 'open command window here'.

How do I know where the ffmpeg path is?

It's the folder that contains ffmpeg.exe - probably "C:\Program Files (x86)\ffmpeg\bin." If it's not there, you'll have to search your "C:" drive for the location.

My avi is on my desktop. It is called 000078.

Just "000078", not "000078.avi" ? Might be a bad sign. Go ahead and rename it to "000078.avi"

Now, open a command window: in Windows Explorer, shift+right-click the desktop (or wherever the video file is), select Open command window here,

Type or paste this in the command window:

"C:\Program Files (x86)\ffmpeg\bin\ffmpeg.exe"  -i "000078.avi" -codec copy "000078-fixed.avi"

(replacing "C:\Program Files (x86)\ffmpeg\bin\ffmpeg.exe" with the actual location) and hit ENTER.

Good luck! In the event of an error, copy the command output and paste it in your reply.

If your video is in another folder go to that folder and highlight the video and left click shift and select 'copy as path' and paste that into the command line where ffmpeg is.

Not a bad idea. It's easier for someone who doesn't know ffmpeg.

Yes, even if the disk wasn't used after deleting the file it's not likely a 31 GB file was contiguous enough for undelete utilities to recover them. Unless the files were defragged lately.

[Nawaffles]

I got the command going, but I get this error, "000078.avi: No such file or directory"

[Nawaffles]

Oh Sorry about that. I just forgot to put the parenthesis as part of the name. The file was (000078).

[Nawaffles]

It has been going perfectly, but I now get this error in the middle of the operation, "Operation not permitted".

[Nawaffles]

I've only got 5 minutes of the 11 minute clip...

Was this file on the OS drive, or was it on a separate drive. And has this drive been written on since the accidental deletion. As there is better recovery software out there like PhotoRec, but it has to be run through a command promt.

[Nawaffles]

The file was on the OS drive.

[Nawaffles]

I didn't defragment or do anything to the drive.

[Nawaffles]

The ffmpeg is working, but it stopped almost halfway through with the error. "Operation not permitted". If this could be fixed that would be perfect.

Just a quick reference here... When you use a command line editor (DOS/CMD) when you come to where you want to enter the complete path of a file, just drag and drop the file to the DOS window and it will fill in the path complete with quotes if necessary.

Example:
<drag and drop ffmpeg.exe here> -i <drag and drop your video here> -vcodec <whatever you wish> -acodec <whatever one you want> "outputfilename and path and extension"

and you will get:
"c:\path to ffmpeg" -i "c:\path to video" -vcodec libx264? -acodec libavaac? "c:\path and name to output"

Just a note to make it easier.

Was that a Windows error or an ffmpeg error? Screenshot please.

[Nawaffles]

Here is a screenshot.

That's a fatal FFmpeg error. Looks like it tripped up on unexpected conditions in the file. If I were you, I would try DivFix++ which is in the software library here..

[raffriff42]

I agree, for the second time, with the DivFix suggestion. Nawaffles, please try DivFix++.

For the curious, regarding "Operation not permitted", it's error code EPERM, which is rarely used within ffmpeg, in fact it appears in only three files: concatdec.c, rtsp.c and os_support.h. The last is the likely source: a function called win32_rename. It looks to me like it's a directory write permission problem - but who knows, unexpected conditions in the file (ie the file is damaged/unrecoverable) can cause a lot of strange things to happen.

[Nawaffles]

I tried DivDix and I get the error, Frame size is too big and another error about paramaters.

[johns0]

Delete the file and give up,too much work to get it back,just save the file you already salvaged.
