How to fix AVI

posted in General

I have a huge AVI file, about 100GB. It was recorded by my computer’s webcam. I am not sure why this camera software produces such huge files, the length is only an hour but I could play it without any problems. Suddenly I cannot play it anymore. Only the first few seconds are played, then it just shows me the green screen.

I tried opening it in VirtualDub. It went into “reconstructing missing index blocks” mode, took almost 20 hours to complete 100GB file, did not fix anything - it thinks that the file has only 12 frames.

GSpot is saying “99GB unneeded bytes at the end of file”

DivFix doesn’t even open the file, says “Input error 301”

What can I do to fix the file? reply

You can try the following steps to fix the video.
Step1, I recommend you use Data Recovery to recover it.
Guide of Data Recovery

step2, If you get the video after step1, you need convert it to a small size for safe storage. Use the tool to do.
Video Converter

Please let me know if you still have problems. reply


Didn’t work. Data Recovery is apparently just looking for the lost files and nothing is lost in this case. The file is there, it just does not play. reply


Try VLC to fix the avi file and Open VLC, click on the Tools menu > Preferences

2.Select the “Input&Codecs” tab and scroll to the “File” section.
3.For the “Damaged or incomplete AVI files” option select “Always fix”.
4.Click on the Save button to validate. reply


VLC briefly displays “Fixing AVI Index” box (1 sec), then shows the playback window but it shows the length as 0:00 and only the first frame is shown. reply


I found an article that introduced how to fix corrupted AVI files.
Hope it can help you.



I have tried all methods in this articles. None have worked. The repair programs that do not think that it is a corrupt AVI in need of a fix. They think that it is a good 3-seconds AVI and just ignore the 99GB at the end.
It is like there is a pointer somewhere, saying “this is the end”.
Any ideas how to remove this pointer, recreate the index completely? reply
