Trying to repair an avi that wont play

[news]

I have a little camera i use on the front of my bike. First day I have used it and I've had an accident! Typical, that file doesnt play.
The original file and is 326MB in size.

Steps ive tried
1.Tried opening in VLC, nothing, doesnt even give a 'Broken or missing index' error.

2.Tried DivFix++ it shows this:
Index frames detected.
Error detected at byte: 2227224
Skipped 8 bytes.

New Stream Size : 55860
Total Error Count : 72
Total Frame Count : 97
Video Data Frames : 70
Audio Data Frames : 27
And gives me a 60kb file that has no video when played in VLC

3. Tried RemoRepair, it gives a 4.24 minute file which is audio only. It also give a BMP file which is a still of the video.

4. Repair Video Master says 'Repairing Video Index (aggressive mode)' and give a 10kb file with no video

5. Bandifix gives a 'File is not corrupted error'

6. Tried playing in Potplayer it gives
'Unable to grt video/audio':
ync Reader::Output

==========================
Unable to get video/audio data.

7. Digital Video Repair gives 3 second 302mb file which doesnt play in VLC, although kind of does in KMplayer

8. Tried playing original file in KMplayer, it opens and starts playing the audio, but you cant scan through it. You can hear the accident right at the end
Playing the video generated in step 7 give a 5 second file, it shows a still picture (a different one to step3) and some audio.

9. Avidemux says it cannot open file.

10. Tried ffmpeg. Ran command prompt, went to where ffmpeg was and ran ffmpeg -i "f.avi" -c:v copy -c:a copy "good.avi", but got ffmpeg is not a recognised program. I checked but there is no ffmpeg.exe.

11. Tried Any Video Converter. Attempted to transcode avi into avi, but it didnt work.

So yo can see I've tried a few options! Theres definitely some audio there, possibly some video, as I have seen still images. Does anyone have any further things I can try?

VirtualDub or VirtualDubMod. If neither of them can open an AVI I tend to just give up, aside from trying MKVToolNix. If VirtualDub(mod) does, under the video menu select "direct stream copy" for the video compression method before saving it as a new AVI.

You could also try opening it with MKVToolNixGUI and remuxing it as an MKV.

Many thanks for the reply!
I tried virtualdubmod, it gives the same Agressive Mode, but it does take a little bit longer to process. The result is the same though. I dont get any video or Audio

I tried MKVToolNix, i added the source, it shows there is a audio and video track, i click 'start muxing' and it gives a 5KB file.

Does your camera save the video on a SD card? The reason I mention this is that often when the power to a camera with a SD card is interrupted,
the video file is trashed.
And some cameras use 'odd' formats. GoPro is one of them. Odd formats can cause recovery problems. Nothing against GoPro.

You say the file is a 'AVI'. That isn't really any description.
AVI is a container name and has many, many formats. Most times we use MediaInfo here to show what the real format of a video is.

You mentioned VDMod and VD. If you may be able to use the HEX editor on either program, and that may give you some good info.
Most videos are just a jumble of numbers shown in a HEX editor. If it's mostly zeros, probably nothing left of the video.
