VirtualDub..what the heck is going on?

[HeatM1ser]

I'm trying to use VirtualDub to combine 50 AVI files. I recorded a match in a game called League of Legends, and it split it into about 50 AVI files. I open the first file, then I append 9 more and choose my compression method. I only do 10 at a time because it says it will take 49 hours for all 50 to be combined and decompressed. Anyway, I'm confused about a few things. Firstly---when I combine the 10 videos( 40GB), does it really take 8 hours to complete the decompression? Maybe I'm doing something wrong. The other thing thats confusing is that when the first 10 of 50 are finally finished decompressing I am left with a video thats 6 hours long(the match was only 40 minutes long), and includes all the data from the other 40 videos that I havent tried to decompress. I'm confused as to whats going on since I only loaded 10 of the 50 AVI's in for decompressing. Can someone provide some insight or advice?

Hi!

Are the original 50 captured .AVI files uncompressed or, perhaps, lossless (video and audio)?

Possibly the 50 avi-files are already appended, when you open the first one. So if you try to append the second, in reality you also append the following 48 and so on.
Do the names of the avi-files end with subsequent numbers and is the checkbox in virtualdub "Automatically load linked segments" checked?
Look at the length of the video if the first avi is loaded.

Im not at home to answer these questions yet, but each video is about 1 minute long. When I open each individual video, it does not play the entire 40 minute, and only plays the 1 minute that was recording in that particular AVI.

Unfortunately, as far as the file name, I do not know. When I started to jin the files, i changed the file names to 1.avi, 2.avi,3.avi ect

Did you set it to "Fast recompress" or "Full processing mode"?
Fast recompress doesn't change the colorspace.
Your recorded video might be RGB and it's converting it to YUV 4:2:0 or other.

It would also depend on your system specs.
Processor speed, number of logical cores, HyperThreading?, Video RAM size.

"Decompressing", as in a full uncompressed lossless AVI file?
Might want to try UtVideoCodec. Lossless vfw codec. It will take up significantly less space than a full uncompressed AVI.

Ok, it looks like all I had to do is load the first video and then append the 2nd video in the chain. Its decompressing now, and seems to be automatically appending all the other AVI's, too. Thanks very much for the input!!! Its good to see that all 54 videos(212GB worth of data) can be decompressing in 45 minutes instead of 8+ hours. Phew.....really appreciated :)
