How to record a demo file (.dem)

[Cable]

Introduction
A demo is a source recording that can be recorded and watched by typing simple commands in the console.
Recording demo's can be very useful for film creators like myself, But they can also be great proof for reports here on the forum and such.
Step 1:
While you are in game (TTT for example) press ~ to open your console.
(Your console MAY NOT be enabled. To enable it, Go to your Garrys mod options, Go to Keyboard and Mouse settings, click on advanced settings, and check the box that reads "Enable developers console"
Step 2:
Then you're going to type "record *You can put any file name here*"
So for example, Someone was hacking in TTT, I would spectate them and type in the console "record speedhacker"
It will then start recording, and it wont stop recording until you type stop in the console.
Step 3:
Once you've captured proof with the recording, The demo file can be found in your steam folder under
Program files/steam/steamapps/*your user name*/garrysmod/garrysmod
The file will be in there. From there all you need to do is upload it to any upload site. For example:
http://www.filesmelt.com/ or http://www.mediafire.com/
Once it's uploaded, Just simply make a report following the reference, and enter the file download link for proof.
Additional Information:
If you want to watch the recording yourself, go back into Garrysmod
open the console and type in "playdemo *file name here*"
So once again using my example, I would type "playdemo speedhacker"
The demo would start to play.

I need to note that some keyboards are not 'US' keyboards, so even when you enable the console, you can't open the console.

That's why you use Launch Options

1. Right click the Game at the Library

2. Click Launch Options

3. Write -console

That'll automaticly open ALWAYS the console, when you run the game.

Or, you could just mess up with the configs like bind x "toggleconsole" put that to your autoexec, or any config.
This works ONLY while playing.

tyvm! i always wondered how to play my demos

[Dale Feles]

Can you convert your files to .avi and such?

[Don]

Can you convert your files to .avi and such?

No, you'll have to re-record them with a program such as Fraps.

You can use fraps to record the demo file.
Just play the demo in game and turn fraps on.
This is how i make ALL of my gmod videos.

asdf don beating me to it

EDIT: I forgot, Gabe Newell's bullshit engine update prevents this way to work. Use FRAPS.

[Cable]

There is another way to make them .avi or any other format

Code: [Select]

host_framerate 30
startmovie [filename] [video format]
playdemo [demo name]
Once it is done, type "endmovie"

Ah yes, I forgot this way.
Fraps is easier imo.

[Hitman]

Ah yes, I forgot this way.
Fraps is easier imo.

But this way doesn't decrease fps and it also has good quality.

Yes you can

playmovie <dem> mp4
playdemo <dem>

Wait for it to finish then the mp4 will be in the gmod root dir

[blαh2355]

For some reason, my gmod didn't have .mp4 extension, only .avi

[Deacon]

Yes you can

playmovie <dem> mp4
playdemo <dem>

Wait for it to finish then the mp4 will be in the gmod root dir

this is broken

Have you downloaded an MP4 encoder?

Also, i must say using startmovie avi (or something like that) doesn't actually make it BEST quality. Best solution is to make them to pictures, then put them together with VirtualDub. I know, it takes lot of space, but i think it has better quality.
