You need to explain what your project is. Compression usually is used for compressing from one format to a smaller  package for storage or transmission. If you are coming from a video camera that uses tape you can compress to DV AVI or MPEG-2 in real time with good quality. This is called on-the-fly compression. If you are streaming live then it would be wise to have the format already converted that you are going to stream or use a streaming server that will do on-the-fly streaming.

It's for in-game video recording, I tried ffdshow codec with h.263 encoding, it seems to give good result but to stay fast I must increase a bit the compression which decrease quality and the file size is very ligth, maybe there's faster for the same quality with less compression ?
I don't know what in-game video recording is. So I'll presume that you are playing a game and you want to record it in real time. Are you using screen capture to do this?
Although H.263 was a very good codec, it is now quite old -- actually used in the latter part of the 90s for video conferencing and also flash.  They now both use H.264.  I'm not sure how that compares with H.263 but I know that H.264 has around twice the transmission speed and half the storage space of MPEG-2, which still is the current DVD and broadcast standard codec.

I tried to download yesterday the h264 but as it didn't appear in my codec list I tried with 263 I will retry...
It's in a game I am developping, the video is created inside the game, not with an external program.
I think you need X264.

I think the solution was correct but I didn't find how to use it.
