Repair avi file?

[David Banner]

I have damaged .AVI file from my dashcam which i want to join in solveigMM video splitter but it won't open in solveigMM . if it did i could cut the piece i want and that would be a new file so may be ok. The damaged file plays in VLC so i did a screen record with camtasia which says it saves as an AVI if you don't need sound i think it is. i don't need sound. But the AVI from Camtasia is not compatible. Neither is one from aimersoft video converter

can I repair an avi. It is only 2 mins and i only want tens secs. This is the media info from the corrupted file

Anyone had any experiece with this https://www.risingresearch.com/en/dvr/ i see people use it here, i got a low risk warning from AV

Try to remux it to mkv:
ffmpeg.exe - i "yourfile.avi" - c copy output.mkv

If it plays in vlc it is not damaged.


Try avidemux to see if it will open in that and create your split there.

ffmpeg.exe - i "yourfile.avi" - c copy output.mkv

but then i will have an mkv and the joiner needs all the files the same

What is it you're trying to do? In the first post you said you're trying to join (to another file?)
then later you said you're trying to extract 10 seconds

[DB83]

And even if you extract that 10 secs to 'join' with another, as you said BOTH files have to be the same. That does not mean that both are simply .avi they have to have the same codec.


We might also need to see the mediainfo report of the other part of the 'join'

i want to take ten second out and then join that to others. But they all have to be the same type of file

You may have to re-encode both files to make them match. Should be simple enough
whether you use an Avisynth script or not

Not by me you're not. I simply added some verbiage to complement your post

I don't know how to re encode avi files. anyway there are several to join together. The corrupt one is just one.

First of all, try opening the problem file in Avidemux and see if it will let you save the seconds you want,
leaving video and audio at copy (on the left).

If it does you can append the new file and the second file in the same program

That bad file shouldn't be hard to deal with. MJPG is an all intraframe codec. You should be able to open it with VirtualDub, select Video -> Direct Stream Copy, then save it as a new AVI. That will rebuild the keyframe index. Or use fmpeg to remux it.

ffmpeg -fflags +genpts -i input.avi -c copy output.avi

But you won't be able to simply join it to other AVI files unless they also use MJPG video and PCM audio with the same properties (frame size, frame rate, sampling rate, bit depth, etc.)

The file is only 19 MB. Why don't you just upload it here and someone will take a look at it.

i just saw that, thanks. I will try it tomorrow
I tried that and while vlc did repair it and it played it would not load into the solveigMM video splitter. It does not stay saved apparently

will try that. All the files came from my dash cam so should be same properties. Thanks

Edit:I used fmpeg to remux the file. it worked. Thanks jagabo you are always very helpful
