I have a video that is in avi format. When playing the video only about 15 seconds of the total 1:15 file actually plays. I have use files such as divfix to fix this file, but all they do is cut out the part after 15 seconds. Is there anyway to fix this file to view the whole file and not just the first small part? I thank you all.

Sometimes not. First drop it into Gspot 2.70 and see what information it gives you. Specifically length, and does it show as correct? You can also try to render it there with the buttons on the bottom left.
I usually try to load the videos into VirtualDub or VD Mod. Use 'File>Open video file'. Then you will see a new menu. Check 'Ask for extended options after this dialog', then select your file. In the next menu, select 'Re-derive keyframe flags'. This will sometimes fix a bad index.
Then when finished, select 'Video>Error mode' and check 'Decode even if the result may be garbled'. Then 'Scan video stream for errors'.
But too often if the file is badly corrupted, you will get the same as you got before, just the first part of the video. Though the video may be showing a proper length, there may be no data after that first 15 seconds, at least nothing recoverable as video.
And you might try playing it VLC Media Player. It can handle missing and corrupted frames most times. If it can play it through, you may be able to use the transcode feature to save it.
If neither methods work at all, there may not be a lot of hope.
But other members may have some ideas. I never had much luck with 'repair' programs as they seem to just try to fix the header or the indexing.
And welcome to our Forums. -
thanks for the welcome to the forum. I am not one to ask for help but I need it for this issue. I have been trying to correct this issue using VirtualDubMod but when I first open the file this is what I get.
Avi: Index not found or damaged – reconstructing via file scan.
Avi: invalid chunk detected at 29386210. Enabling aggressive recovery mode
then when it plays the file it ends right at the point it cuts off at, which is 15 seconds of the video. I know the video is much longer and has played correct before. What I am not wondering is if there is a way that I could use some sort of a splitter to just play the file after the 15 second mark which would bypass the corrupt frame. Any thoughts? -
ok its getting to the point now where I will send you money if you can help me fix this
-
In VirtualDubMod, after scanning the file, hold down a shift key and move the frame slider around. Can you move to the end of the video?
-
No the file is half the size it use to be. Once it hits the corrupt frame the program switches to aggressive mode and says that it is reconstructing Missing Index Block...Aggressive Mode. Not that I know what I am talking about but I tried using different AVI Splitters, but none of them identify the file at all. The only one that did was the HJSPLIT file, but once those files are split up they turn into files ending in .000, .001 and so on and they cannot be played. 20 bucks via paypal to anybody that can solve this for me.

to be more specific the file, after scanning in VDM, is 28 mb and the original file is 50 mb, so we all know the data is there. The question is how do I get to it, erase the corrupt frame and have it play as normal or at least split it in half and play it in two files.
-
After scanning the original file in VirtualDubMod but before saving, hold down a shift key and move the frame slider around. Can you move to the end of the video? If so the fix will be easy.

I can't get it to the end of the file. It only scans to 15 seconds (end of the bar on the program) but the file is over a minute long. I just opened the file in Gspot 2.21 and under file it says the size is 50 mb. Under stat is says "This is an invalid AVI file due to corrupstion of the data in the header. This is a serious problem, and this file is not likely to playable (even though I got half of it to play) Details: While processing chunk /RIFF:AVI , found bad length value 142307472 at file offset 0x00000804

Did you hold down the shift key while moving the slider?
Oh wait, you said the bar only shows 15 seconds. That means it was not able to recover anything past 15 seconds.
You can try using DivFix. It might have better luck than VirtualDubMod. -
Yes I did, I just scanned it again to make sure. Right after those errors the partial video showed up on the screen. I did not hit play, rather I held in shift and tried to move the bar all the way to the right. It did go all the way to the end of the screen, but that was at the 15 second mark.

That's a really old version of g-spot. Update and try again. You may get better information from it. The file may be 50 MB, but depending on how you downloaded it, you may well not have filled it with video data. Many downloaders and torrent clients re-allocate space on the HDD so that the download doesn't fill up the disc and stop part-way. To do this they create an empty file, then fill it with the data as it downloads. If the download does stop, or you copy the file before it completes, you get a file that is the full size, but does not contain all the video data.
I also suggest you avoid double posting or you will simply annoy the moderators.Read my blog here.

When I go to the very end of the video on the bottom of the program it says MJPEG decoder: Access violation caught. Source may be corrupted
-
Given the size of your file, and the error message, it sounds like MJPEG. After opening it in VirtualDubMod use File -> File Information. That will list the audio and video codecs.
If you want to upload the file I'll take a look at it. -
here is the file info screen print. Let me do that gspot one now

no I do not. It was sent to me. I guess the only thing I have to do is try to get the file again right? Well thank you for your help though. I just assumed that since the file was 50mb and when I played it in VDub it was shorter, I could then recover the missing parts. Thanks again and let me know if you can think of anything else.
