Hi all. I recorded a video with Lineage 2's ingame recorder. The avi file is 1.7GB (21.33 minutes). When I first opened it in WMP only the first 1.5 minutes played. Weird! I opened it in VLC and it temporarily fixes the index problem and I'm able to play the whole file but I have yet to find a way to permanently fix this. When I tried BandiFix and Remo Repair they both said the file didn't need repairing. I tried to record it in VLC after the index file was repaired but the quality is terrible. DivFix hung up on trying to check for errors. I tried convert/save in VLC and ffmpeg but they both start 1.5 minutes into the video, the file size is reduced by about 696MB, and the sound is out of sync (meaning the sound starts at the very beginning of the vid). This really has me stumped. This video has sentimental value and I'd really like to permanently fix it. TIA.

Perhaps there is something else wrong with the file.
I created a test MJPG avi file, chopped off the end of index in a hex editor.
Opened the file in Virtualdub2 and video/scan stream for errors
verify that you can scrub to the end of the file. If it's good set video to direct stream copy
Found a good youtube vid where he uses HDX to open up the bad avi file and a good one as a reference. Then he finds a corresponding line in each file and copies the lines in the reference to the bad index file, takes it into virtualdub and does the direct stream copy thing. Doing it now. I have nothing to lose. Got backups of the original. I'll let you know how it goes.
UPDATE: Didn't work. I copied everything above this line (LIST´*ű?movi01wb) in the ref file and copied it to the bad. Arggg!

In VD2, go to 'Video>Scan video stream or errors...' After the scan, look to the bottom of the VD2 screen and the errors are shown.
Usually, 'O feames masked (0 frames bad, 0 frames good but undecodable', if there are no problems.
Scrub by moving the time slider through the video to the end.
If OK, save the video in Direct stream copy with the preferred format. 'Flile>Export>Stream copy'.
The HEX editor will just give you some numbers and letters. Not easy to interpret. And the file can be very long.
Someone else can probably explain about the index file there.
redwudz is right, I only used/mentioned the Hex editor because I purposely created a file
with a damaged index to simulate your situation. Did not mean to infer you use it yourself!
Update: did another scan (I had forgotten to turn on report errors.) It says "0 frames masked (0 frames bad, 0 frames good but undecodable. But it still starts 1.5 minutes into the file.
The only way I'm able to view the whole file is via VLC and going thru that temp index repair.

Shouldn't be, as long as you set the encoding properties properly.

Don't know where to go from here and am about ready to give up. No word from this yet:
"Shouldn't be, as long as you set the encoding properties properly.
Where do I do that? What should they be set to and should they be set prior to rebuilding the index and before recording?
P.S. It's the audio that is messed up, not the video. There's this awful buzzing sound and it lags at times."
why don't you post the whole file to a file hosting site and perhaps one of our members will
take a look at it. A long shot perhaps, but better than the progress made otherwise
It was hard to understand just what you meant before (very elliptical and confusing).
Were you able to view the whole program ever? With VLC after re-indexing?
Was "bad quality" refering to video or to audio? or both?
Don't obfuscate bad playback quality (issue with the source, player) with back re-encoding quality (issue with the process/settings, codec, user, etc).
A screen recording can be set to give you exactly what's playing back. If it can play back good quality in VLC, record that. Then you have a non-corrupt version.
For detailed screen recording options, I use OBS these days. Match the video framerate, audio samplerate, color system. Give it equal or better bitdepth compared to the source. IIWY, I'd use a lossless codec option for video & audio, and then if you later want to create a highly-compressed (AVC or HEVC) MP4, you can do a CRF encode and give it exactly the quality you find acceptable.
If you could never play back some form of the clip without issue, you're probably screwed.
I have always used Avidemux when I have come across an avi with 'broken index' issues.
Open the file in Avidemux. Leave 'Video Output' and 'Audio Output' settings to 'Copy'. Click 'File' then 'Save'. Give the file a name then click 'Save'.
The resulting file should have it's index repaired and play without issue.

When I record the playback after re-indexing that recorded version is when the buzzing in the audio occurs and the video lags at times. What is OBS? I don't know where to find this to match the video framerate, audio samplerate, color system and give it equal or better bitdepth compared to the source. Nor do I know how to create a highly-compressed (AVC or HEVC) MP4 OR a CRF encode to give it the quality I like.
Sorry I'm such a noob.
OBS = Open Broadcaster Software. It is often used for streaming (to Twitch, etc) but is equally adept at screen recording.
You should already know about your media's info from MediaInfo, so take that knowledge to use for those settings.
Your playback & recording pass will create, if you follow my suggestion, a totally new temp file that is HUGE because it is losslessly compressed. Then take that and use one of many apps mentioned here for the final conversion, of which there are many helpful tutes, demos, examples. Things like Handbrake, MeGui, Hybrid, or even CLI tools like ffmpeg. If you want, after, you could delete the temp recording file.
And if you are new, this a good place to learn about such things. No need to be sorry.
7 x 21.5 = ~150GB. How small is your drive?!
Space is still fairly cheap these days (BBuy has 1TB drives for $50). Don't skimp.
And BTW, in the grand scheme of things those actually aren't that big - it's not like we're talking 4k or higher, or stereo3d, or 32bitHDR, or other raw format.
Plus, I don't quite know where you got that number.
1920 x 1080 x 16bits (422yuv) x 30fps ÷ 2x average compression is around 500Mbps or ~3.7GB/minute, or around half your figure.
