Except this is a horrifically bad idea because you go from being pretty badly hard drive limited to “I might as well be doing this on a pentium 3 for all the difference it would make”-hard drive limited.
What do you mean? I’ve not ever run into any issues with this.

If someone is still wondering, here’s the basic way to handle demos. It also includes a way to export movies directly to the AVI format.

I don’t see it.
All I see is the same way everyone here usually does it but instead of making a tonne of .tga files it makes a single .avi
iirc, isn’t this method unreliable in comparison to the .tga method? I remember trying before replays came out and had to record the same 20 second clip five times because image in the avi was fucked up.
Do you want to convert an entire demo? e.g. ~30mins of footage? If so I would record to jpegs and not tgas.

That might be the case, but I’m assuming that you’d want to edit the video anyway as demos are what the are.
And also, that is the basic guide. Using recording tools might be a good idea, however.

I think you can only record to .tga using the Source Engine’s build in movie making feature.

It works, but it’ll render out a shitload quicker. If you’re editing say a 400fps export with frame blending, your hard needs to read nearly a gigabyte of files just to create a single second of video. Consider that’s going to take 8-15secs on the average hard drive, that causes a big performance issue.
Even if its 30fps, that’s still ~70MB/sec which is right on the line of typical maximum copy speed of a hard drive.

You can use jpeg in the startmovie parameters, and jpeg_quality, theres some obvious compression visible, but for a full 30mins I can live with it.
As skyride says, I tried 30fps and tgas once. Oh boy..

Yeah the rendering takes a while, but then I don’t ever use frame blending (because I like to watch my own videos afterwards) and also, rendering is slow anyway. An extra few minutes isn’t going to kill anyone, I’m not fussed about it.
Anyway, you would render uncompressed with vdub before editing then? Surely that adds a whole lot more time than it saves?
