Title: How do I capture video and audio generated by software ?
Post by: Igor on 26/04/2008 13:38:26

Is there a computer programme which will record the images and sound generated by other software which is running simultaneously?,
i.e. capture the video display (and sounds) in a video file.

For example such software would permit a gamer to record themselves reaching level 99 on space-invaders,
and post the video of their achievement on U-tube. (My application is not as geeky) .

(PS  I’m using windows vista)

Thanks for your link Dr Beaver,
that's the very thing I'm looking for.
I suspected such a thing existed but I didn't know what it was called. 

My only concern is that such a programme may slow down the original software.

yeah it will, your computer is doing alot more work, not only is it rendering the game you're playing but its taking every frame, encoding it somewhat and writing it to a hard drive. That is if its a game you're using it for I mean. It should be fine for things that aren't very taxing to render.

I use a program called fraps for this, you can set it to record at a lower resolution and/or framerate so that its less taxing on your system.

If it is a 3d game you're talking about, with some games you can actually record a demo file while you're playing, which isn't a video file but basically a log of all the input of all the players in the game, and when you play it back the game renders it all again. So for these games its easiest to do that and then do your video recording while you're playing back the demo.

You're right Maddius, the "myscreenrecorder" worked well but it did noticably slow down the original programme (not a game). Even at the highest frame rate (30fps), which understandably uses lots of memory, the recording was also little jerky. The best "temporal coversion" of "myscreenrecorder" is 0.75, i.e. the recording is only 75% of the original, (OK for U-tube).

Those sort of programs are generally used for recording tutorials (to show typing or mouse actions). They're not meant to record live gaming.

Games take up a lot of processor power; so unless you've got a totally separate processor to handle the capture & recording to disk, it's inevitable that your game will slow down.

Heah, you can use some <removed> to help you capture video and audio on your computer, the one I used can help me do the job well. I always use it to <Removed as spam>, and the video I got is the same as the original video.
