What's strange is that when I opened the file in VirtualDub, its window that says 'reconstructing missing index block' skipped ahead to about 3.75 gigs into the video. Also, when I ran Virtual Dub, it recovered a few minutes toward the end of the video (concluding with the 45 seconds I'd already managed to get). Honestly, I have no idea what any of that means, so maybe you can help translate it for me. Seeking in the video stream may be extremely slow. Enabling aggressive recovery mode.ĪVI: Keyframe flag reconstruction was not specified in open options and the video stream is not a known keyframe-only type. I opened the video with VirtualDub, and it gave me a few warning messages:ĪVI: Index not found or damaged - reconstructing via file scan.ĪVI: Invalid chunk detected at 956934288. No image loaded, and the scroll bar at the bottom immediately jumped almost all the way to the end of the video. I had also tried playing it in VLC Player but with no success. Was there anything else specifically that I should check with it loaded in GSpot? I'm not familiar with that program, so hopefully I did it right, but here's what it said: But anyway, here's where I'm at so far:įirst, I opened the file in GSpot. I had no idea that there was a 4 gig size limitation on video files. Okay, I checked my drive's format, and it is indeed NTFS, so at least there's that. Thank you in advance for any help you may be able to offer!! If there's anything I left out, please let me know. At this point I'll be happy to restore even just a part of the file so I don't have to go through trying to record the entire hour and a half demonstration again (especially if there's a chance I may hit a similar problem). So is there any hope? What should I do? Please help me if you can! As I said, the file is four gigs in size, so I figure there's gotta be at least something salvagable in it besides those 45 seconds.

I went ahead and downloaded a program called 'ASF-AVI-RM-WMV Repair' to see if that could help, but all it was able to do was create an avi file consisting of a random 45 second segment from toward the end of the video. But in real player, it at least accurately lists the length of the video (which as I said is about an hour and a half), and the scroll bar moves as it tries to play it, but nothing happens. And when I try to open it in real player, I get a frozen still frame that looks like the frame was shifted over horizontally and vertically so that there's a big black cross going across it. When I try to open the file in Windows Media Player, it simply says that it can't prompts me to close the program. I've never had this problem with smaller video files I've made in a similar manner - ones only a couple of minutes long - but sure enough, the one time I need to make an extremely long file, I hit this problem. avi file, but now, after all that work, it looks like the file is corrupt and I can't get the dang thing to open (I don't know why it got corrupted, but that appears to be the case now).Īnd it's a huge file too! About four gigs (I had the settings at the highest quality possible figuring I can always compress it down later if needed). After I was done, I saved the video as an. I won't bore you with the details, but needless to say, it was an hour and a half demonstration. I was using a program called Easy Screen Capture to capture video from my desktop to be used for a lengthy 'how to' demonstration.

Okay, I've seen a handful of topics in this forum dealing with trying to fix corrupt video files, but they're all kinda different from my problem, so I decided to start a new topic.
