I have recently started watching the fab serialized movie Bloodspell, which is created entirely in Neverwinter Nights.
Bloodspell is released in a series of 6-7 MB files. So far they’re up to part 7. This certainly makes it easier to download on to my laptop and enjoy 10 minutes of Bloodspell at a time. However, I want to burn this to a DVD and watch all seven at once on my home DVD player. Before I did this I just wanted to string together the 7 .avi files into one larger file. (I can’t stand a mess!) Sounds like a simple request? Guess what, in my distro, Ubuntu, it is!
This will most likely work on just about any linux distro that includes the ability to install mplayer/mencoder.
First, let’s get the right programs.
sudo apt-get install mencoder mplayer
Now that the hard part is out of the way, we’re going to make use of the wonderful cat command. I’d renamed each Bloodspell video as b1.avi – b7.avi. Now to string them all end to end.
cat b1.avi b2.avi b3.avi b4.avi b5.avi b6.avi b7.avi > bloodspell.avi
Now we’re 2/3 of the way there! Stringing together .avi files can cause a breakdown in the sync between video and sound. So, we’ll use mencoder to sort things out.
mencoder -forceidx -oac copy -ovc copy bloodspell.avi.avi -o bloodspell_final.avi
That’s it! You’ve got one contiguous .avi file now containing all seven bloodspell releases to date. This will of course work with other .avi files. It will also work with .mpg or .mpeg files as well.
Later we’ll discuss getting this .avi file on to a DVD so you can watch it anywhere.
geek out.

This will also work:
mencoder -oac copy -ovc copy file1 file2 file3 … -o final_movie.mpg
and please stop talking about ubuntu like it was a godsend, everyone knows that archlinux is much much better

Hey, thanks for the mencoder tip. And what is this Archlinux that you speak of? Damn. Now I’ve got another distro I’ve got to go install and check out.

avimerge from the transcode package was designed for this task. and as far as i know, it was created before ubuntu. ;P
avimerge -i b1.avi b2.avi b3.avi b4.avi b5.avi b6.avi b7.avi -o bloodspell.avi

guille, what version of Ubuntu are you running this on? Are you using non-stable repositories?
February 28th, 2008 at 3:48 am
Listen to what Mr. Pr0n said. Forget that UUOC and use mencoder directly
April 29th, 2008 at 3:56 pm
Try using Jfuse (http://www.jfuse.com). It joins all types of media files.
October 15th, 2008 at 12:30 am
using ubuntu 8.04, with mencoder installer. I joined the mpeg files using cat then encoded both ways first tried arsgeek instructions and joined 1 file, then used Mr Pr0n instructions and made a second file. The issue is that I have sound but no video ? any ideas….. thanks for the help
November 4th, 2008 at 2:22 pm
lalo: totem movie player does not show the video, but it is there. Try opening the file with mplayer or avidemux. However, there seems to be something wrong with the file created that way: both mplayer and avidemux refuse to fast forward it; I don’t know what causes that problem.
November 4th, 2008 at 3:15 pm
OK, I figured it out. If you want to merge mpg files you must use this:
mencoder -oac copy -ovc copy -of mpeg part1.mpg part2.mpg -o all.mpg

Should be:

@Joe Francais & @nic:
You made my day… I am really amazed to see that people are capable to repeat adverts like parrots, but are unable, unlike parrots, to do a bit of thinking on their own part in regards to the applicability of their comments. This thread is old, yes, but I felt urged to comment:
@nic :
The operating systems the software you suggest require are broken by design and the software you suggest might have a nice gui, but it lacks wider compatibility, basic capabilities, and it is slow and far from efficient. That it all does cost a lot of money doesn’t make these arguments less valid, but instead underscores them in bold.
Besides, Microsoft only now starts considering porting Windows to some decent CPU platform ( ARM ) after they abandoned more advanced platforms in the past already ( DEC Alpha ), like Apple did a while ago ( switching from powerPC platform to Intel’s x86 platform ) .
Accordingly, on up-to-date platforms, your software wouldn’t work, whilst mencoder works since years on all platforms, thanks to Linux and it’s ubiquity.
@Joe Francais :
Though not as failed as nic, please read what the wrapping on a program says: JFuse is propietary software, and available only for Windows and just since recently for MacOS, too. Accordingly putting money out for a program that is usable mostly as a paperweight is not really smart, and the time and effort invested into getting it to run on any decent OS is way better invested in just typing the mencoder – sequence and have the job done swiftly and reliably.
It’s not that I am agaisnt commercial Software – I use MainActor Broadcast and EAGLE regularly with pretty expensive licenses attached – it’s just that, really, commercial software should be au-par with freely available one ( like GEDA equals EAGLE easily, but there are more libraries packed with Eagle at this time ) and not blatantly inferior. When such software then is equal, or even better than free equivalents, however, often the software is incompatible to ones OS of choice, which renders the entire package useless from the beginning.
February 23rd, 2011 at 5:33 pm
@Mr. Pr0n et al.: I tried mencoder without “cat” and it crashed halfway into the conversion process! However, when I ran cat first and only then mencoder, it suddenly worked. Now talk about UUOC…
