Free tools for video manipulation and written material in Linux aren't that vexed to discovery if you know wherever to stare.
Here are my favorites:
Avidemux is a atrip video editor designed for uncomplicated cutting, filtering and cryptography tasks. It supports lots record types, with AVI, DVD compatible MPEG files, MP4 and ASF, victimization a sort of codecs. Interestingly, it's unclaimed for Linux, BSD, Mac OS X and Windows underneath the GNU GPL legal instrument. I haven't tried Mac OS X and Windows versions, but the system runs fine underneath Ubuntu Linux (Dapper Drake).
For file conversion, there's FFMPEG, which is free-but you'll have to swot to use it through with the tell chain. Unfortunately, the MAN page for the system of rules isn't deeply unambiguous.
To save whatsoever of you the preoccupy of figuring it out, here's a express teacher.
Let's say you impoverishment to convert a directory titled MYVIDEO.AVI to the mpg format, which is the info based on by the K3 CD roaring system. After commencement FFMPEG (you can use Synaptic Package Manager), forest fire up Terminal.
From the instruct line, voyage to the brochure where the report is kept. So you could type:
cd /home/user/Converts
to go to the case wherever the file is kept.
Then form the succeeding at the bidding line:
ffmpeg -i MYVIDEO.avi -target ntsc-vcd MYVIDEO.mpg
and hit Enter. That should get the changeover system of rules started, and you ought to see both textual matter roll by in the Terminal framework. Don't accidentally nestled the window, because that will reduce the change. You can minimise it, nonetheless.
To soul an avi database to SVCD format, you would type:
ffmpeg -i MYVIDEO.avi -target ntsc-vcd MYVIDEO.mpg
There's a GUI front-end for FFMPEG on Mac OS X, but I haven't found one for Linux.
For rending DVDs, I use AcidRip. Very simple but red-hot and effective.
