help! how to make quake demo videos (.dem)

[noah99]

i just watched the movie seal of Nehahara from beginning to end and all i can say is WOW!,back to subject how on earth do you make demo files? i cant seem to find any substantial info on it so if any one could explain how?

A .dem file is just a binary file containing a capture of regular network traffic (plus a small bit extra) - that's an important point, because even SP games go over the network transport layer in Quake. To make one, just use the "record" command from the console; couldn't be easier.

That'll give you a basic demo from the player's perspective; to have more (like recamming, for example) you need to hack the file to change some of the data in it. All the info you need for this is in cl_demo.c and cl_parse.c in the engine source.

stop demo
play demo demo4
record demo demo4

To record you can't be in a game, go to the console [~] and type:
disconnect - then type
record demo demo286blah - then load the map you want with
map e1m1 - and when your done
stop recording - and play it back with
play demo demo286blah

I would suggest using Qrack for recording if you want to use the demo in any video production.
With its rain and fog and Q3 particles,low system requirements and Xvid conversion built in, you wont find an easier alternative.
Also you can record at any time and do not have to disconnect.
Even changing maps which will ruin the demo in any other engine
is handled by Qrack effortlessly.
You can just have it auto demo as well and it will name the files for you and record all the time :0
