My apologies if I am posting in the wrong section . . . I'm admittedly a novice and am beyond confused over this.
I have been using Ulead VIdeoStudio 10 SE (packaged with EasyCap device) to capture video from a wireless surveillance camera. I am attempting to capture for approximately 14 hours continuously, which in raw avi is generating huge files.
To handle this, I installed a 1TB drive last night to dump the file to. When I came home this morning, I found a file "uvs110125-002.AVI" in my storage folder, and Ulead acted odd as I logged on. Anyway, the file is over 673GB in size which seemed appropriate given the shorter captures I've done without incident. But when I tried to play the file, it only played for 4 seconds, supposedly complete!
The only clue I see to the issue is that there are two clips listed at the top of Ulead--"uvs110124-002.AVI" and "uvs110125-002.AVI". However, when I click on the "124" file, Ulead throws up the error "Original file [I:\Store\VC\uvs110124-002.AVI] doesn't exist." And indeed, I do not find said file in the folder.
The huge file behaves the same in Nero Showtime, playing for only 4.19 sec.
Any clue what may have happened and how I might recover this file? This file may contain crucial evidence that needs to be viewed.
Many thanks in advance for any help you can offer

Have you tried open it with a video editor like avidemux, virtualdub? Only 4 seconds?
-
I just installed and tried virtualdub; same thing. 4.178 seconds, 342 frames. I'm guessing that ulead did something strange because of the length of video I tried to capture, but I've no idea what.
-
There was a message in virtualdub about the clip: "AVI stream 0 (video) has a non-zero start position of 12 samples (+147ms). Virtualdub does not currently support non-zero start time and the stream will be interpreted as starting from zero."
-
A 14 hour uncompressed avi would probably exceed 1TB anyway.
And if it did I suspect there would be so many dropped frames to render the video un-watchable or even trash the HDD in trying to record it for such a long period and at such high sustained data.
So I must ask, why uncompressed ?. Ulead will capture in dvd quality mpeg2. That would only be some 56 gig.Last edited by DB83; 26th Jan 2011 at 13:52.

Even VirtualDub won't capture for more than 8 hours lossless unless you change the "superindex" settings so I'm not surprised something that isn't a dedicated capture app can't do 14-hour uncompressed properly.
-
There is nothing wrong with Ulead's capture app - use it quite often but only for Mpeg2.
I have had problems with it doing DV - although its own editor can open and use, others can not. Never tried uncompressed for more than a few minutes.
But have you tried opening the file in the Ulead editor ?
