Hello.
Always when playing i'm recording demo of every second i spent playing.
I have captured many cool actions.
I want to do video for youtube.
I know how to edit and compress video but i don't know how to convert .dem files to an avi or seprate images.

Second question is: How to bind key "f12" so every time press it, it starts recording demo with actual date or number in name?

It's how I do it, but it can take a long time and it takes up a lot of space. An easier, quicker way (sound doesn't seem to sync as well with this method) is to do it this way:

sv_cheats 1
host_framerate 30
startmovie moviename avi

Then choose the compression you want to use (you can just leave it uncompressed and compress it after you've put them all together in your video editing software)

next playdemo demoname
after its finished and you're back at the main screen type this and you should find the video in the sourceforts folder or possibly in the hl2dm folder endmovie

You might want to add this if you want it to be HD on youtube:

right click on sourceforts in the steam window then properties and then set launch options and enter this:

-w 1280 -h 720 -window

You should add -window to it anyway if you use the second method because the compression box might not pop up in full screen.

If you are lazy/stupid, use fraps or wegame recorder. Otherwise I'd say use startmovie (not startmovie avi) and then use videomach/virtualdub to piece the TTF files and audio together. Startmovie avi is about as stable as maggie thatcher with my balls in her mouth and chances are you'll crash several times per attempted recording. Google a step by step tutorial as it'll be as valid as anythign anyone here can say, and a lot more detailed.

I would recomend you to use host_framerate 60. Makes it smoother when you want to do some slowmotion effects.
