demo help

Anyone know how to edit demos?

I was sent this demo and he forgot to stop the demo after the match, was wondering if someone could edit it so its just the 1v1?

Thanks

It's actually just a matter of truncating the file immediately after a certain packet.  A Quake2 demo file is the raw server packets that your client received for the duration of the recording, with a serverinfo message packed at the front.  Unfortunately, every Quake packet can be a different, unknown length.  So you can't just, say, chop at 1000 x 1400 bytes or whatever.  You have to consume the packets in order until you reach your desired stopping point, and then truncate the file.

So this is technically rather easy, but I don't know if KeyGrip or whatever will do it for you.

Holy crap 8 meg..  keygrip limits at 2 meg I think.

Cant you just demo the part of the 'demo' that you want?
I thought i'd done that before. start recording demo while demo is running and end demo where the match stops.   
 

eh  tried it. cant record demo due to insufficient deltas!  nice

sounds like you could just guess about where to trim it...  maybe at least make it manageable
