creating videos

[skumar]

hi,
Irrlicht has its own native method for taking screenshots......

Does anyone knows any library that can help us to make videos from the
3d engine.....

Is it really possible to take sequential shots from video memory and to give out a mpeg or avi file?

Well, you can save the screenshots to images and create a movie using e.g. ffmpeg.

To create tutorials (capture images and events) I use:

http://www.debugmode.com/wink/

It's a good free replacement for Adobe Captivate

If you want to capture video you can use:

http://camstudio.org/

It allows you capturing screen regions or windows

Both are free

You're much better off to just use an external tool like fraps and then transcode the result to some format that uses compression.

Hello Marcos,

what settings do you use for camstudio ?
The quality i get is not very good.

Microsoft Windows Media Video 9 and 3ivx D4 4.5 Video Codec work quite good. But the image quality is a little bit pixelized if you do not use "Quality 100%"

Of course Camstasia Codec or DivX Pro(tm) 5.1.1 Codec are superb.

But I recommend you using the Lossless Codec that can be found on camstudio's web page. With quality to the minimum and in the plugin settings "Level 1" I tried with the irrlicht lighting example and I get about 15 frames per second capturing the whole screen (1600x1050) on my old P4 with a Geforce fx 5700 and camstudio 2.0 without image quality loss.

If you want higher rates try capturing a region (big performance improvement). You can also set manually the capture (by try and fail) rate in video settings because auto adjust has a small overhead...

'Taking the train' as we say here... Is possible to play videos in Irrlicht? I like some animated background in menus.
