Zaknafein has interviewed Valve's network and demo coder Yahn Bernier for SoGamed. The questions are mainly about demo recording and movie making in HL (& CS) and HL2 (& CS:S). Since Zaknafein is a movie maker himself (and a good one!) he definitely knows what he's talking about, so the questions are very precise and I learned a lot from Yahn's answers. The interview is quite long and very informative, so I really advise you to go take a look even if you're not at all in movie making.
Here's a preview:I noticed in the HL2 E3 2004 video that you still used commands such as "playdemo" to view demos. Can you tell us a little about the demo recording system in HL2? Are there any differences between HL2 and HL1 concerning demos?
I think the high level commands are pretty similar. The playback fidelity of the HL2/Source demos is much smoother now. We have a couple of new tools, one is a VCR/DVD like Play/FF/Rewind UI element that lets you pause a demo. We made it so you can "fly around" in a paused demo, which is really handy for getting exact screenshots. You just pause the action and fly around. Demos now can have an associated "metadata" file (.vdm
I've been playing cs since version 1.0 came out. Cheers to the people I'm always playing with (and to the ones I've had fun with in the past), they know who they are.
