I have an DVDRip .AVI that is approx. 2.5GB --- I want to split it into parts. First of all, a lot .AVI programs cannot even read a file that big.
(Earlier, I tried ripping the .vob files separately---but I'd have to connect one end of a .vob-rip AVI to the beginning of the next one. When I use VirtualDubMod to join these, there is a/v out of sync problem at the joining segment. Other free AVI joiner/splitter programs out there cause the same problem.)
Anyway, I'd like to split the file keeping everything the same in the original without the a/v going out of sync.
Help?!

If you created the avi file, I would start over.
I also don't understand whay exactly you are trying to do. You have 2.5GB avi, that you want to split into smaller pieces, then put back together? Why are you even splitting it? How about re-encoding to create a smaller sized file?Google is your Friend -
I'm not clear on most of that either.
To split most AVI files, you have to do that at the keyframes. VirtualDub has a keyframe icon that lets you jump to the next keyframe. If you split a video anyplace else, you will likely have sync problems. Xvid/Divx, for example, is poor for editing as the keyframes are every 300 frames by default. Makes frame accurate editing all but impossible. The newest VD can cut most anywhere, then it you just re-encode at the cut and that allows accurate editing.
If you have the original DVD, you could use VOB2MPG to extract the video to one large MPEG. Or VD Mod can open each VOB, but then you are stuck with the joining problem.
I've never had any problem with reading GB files. I've worked with DV files over 20GB several times. -
Okay, thanks. I got that sorted out. Basically, splitting and joining with VirtualDubMod is unreliable. I found a splitter program that works---direct stream copying without a/v sync problem, only wish I had a joiner program that's just as good.
To those who did not understand my initial post, basically, I re-ripped my DVD. The first time, it's one .VOB per .AVI into 4 .AVI files. (It was already split, into 4, but not at the places I want them, so I have to join at some points as well as split.) Then, I reripped into one big .AVI and just involve splitting. -
It would be easier to use a different process. RIP the DVD to your HDD, then use a program such as AutoGK to convert the DVD files to avi. AutoGK can be setup to output a single file, or create separate files of a specified size. You can get excellent results with AutoGK.

I did that but I deleted the files I ripped the first time (cuz I thought I didn't need them anymore), so I had to re-rip and convert.
Anyway, thanks, I already tried AutoGK. Works great. However, I don't know if I'm demanding an impossible task here---is there any DVD-to-Xivd/DivX-AVI converter that can keep the original quality, e.g. colours in their full brightness. I found that there was a huge reduction in quality when I played them on DVD-Player and on my comp. Could just be my hardware is not good enough. -
There will always be a reduction in quality when you re-encode and especially if you reduce the size. But a high bitrate Divx/Xvid can look very good and difficult to tell from the original DVD. AutoGK should let you use a higher bitrate.
Other than that, every Divx/Xvid converter program will have exactly the same quality output if they use the same Divx/Xvid codec and the same encoder settings. It's all determined by that, not the program that is using the codec.
