Creating Movies out of your Game Demos using Adobe Premiere
Converting Game Demos to Screenshots
The first step in making movies out of your game demos is to record the demos to sequences of .tga image files. Before doing this you should note a few things.
* You will need a lot of hard drive space. This process will write thousands of sequentially numbered tga files to your screenshots directory.
* Start by emptying your screen shot folder. This is particularly important if you have any gaps in the sequentially numbered files already in there.
* Before outputting the demos you should lower the in-game resolution to 640x480 or lower. A resolution larger than that will just use up unnecessary hard drive space. The final movies you render will be 640 x 480 or smaller so there is no need for the screenshots larger than that.
Recording Demos to Screenshots
After starting the demo you want to record, drop down the in-game console and type /cl_avidemo 30 to begin recording screenshots to your screenshots folder.
  The 30 represents the number of frames per second that will be written to your hard drive. You can replace the 30 with any number between 15 and 30. 15 frames per second might look choppy when played back but it will help with those tight on hard drive space. Full motion NTSC video runs at 30 frames per second so there is no need to go any higher than that. The demo will seem to run slow and choppy while writing all those still files to your hard drive but don’t worry that is normal. There is a limit of 9999 screenshots that can be recorded. That means at 30 frames per second you will only be able to fit less than 6 minutes of demos in your screenshots folder.

Drop down the in-game console and type /cl_avidemo 0 to stop writing screenshots to your hard drive.

If you plan on creating a long movie that uses many different demos, I find it easier to move my screenshots to a new folder before loading and outputting my next demo. Name the folder appropriately ie: the name of the demo This will greatly help your overall organization of the files when you go to edit your movie, and will also help get around the 9999 screenshot limit.
Config File
I have compiled a seperate config file that includes my demo playback settings and binds to make all of this easier. I have named this config file avi.cfg and it is saved in my baseq3 directory and the main directory of the mods I have installed. To execute a config file from inside Quake 3 or a mod, drop down the in-game console and type /exec avi.cfg (replace avi.cfg with the name of the config file you want to execute). My config also includes some timescale binds to help fast-forward and slow motion through the demo. You can even record screenshots while in fast-forward or slow motion for some interesting "in-camera" effects. In the config file you can also turn on and off certain screen items like scores, guns etc. That all depends on what information you want included in the movie. "1" turns an item on, "0" turns and item off.
