Taksi is a video capture/screen capture tool for recording 3D graphics applications (such as games). It can capture almost any windows application using DirectX, OpenGL, or GDI and create an AVI file using any installed VFW codec or still frames in PNG.

Taksi can support live video compression with any VFW video codec your system has installed (i.e. XVid, DivX, MS Mpeg4, etc).

Supports user-specified key mapping, allowing user to assign almost any key to a particular function (such as video start/stop, screenshot trigger, etc.). Runtime re-mapping of the keys is supported via GUI: user can change keys without having to restart the game.

Custom video settings are supported (see manual.txt for more details about this).

Basically, this allows a user to specify on a per-game basis the frame rate of the captured video, and the weight of each source frame. The weight determines whether a particular frame is captured or not. This allows for creation of smoother and faster videos, when generic algorithm doesn't produce desired results.

Tech spec for v0.7.6:
DirectX 8, DirectX 9, OpenGL and GDI based applications are supported in this version. Video can be recorded at either full-size, or half-size in each dimension (using bilinear minification filter). Audio is not captured. There is no imposed limit on the duration of the video, only available disk space is your limit.

Supported OS: Win95/98/ME, WinNT4.0/2K/XP.
3D Graphics API: Direct3D 8, Direct3D 9, OpenGL, GDI
Screenshot file format: PNG or 24-bit BMP
Video file format: compressed or uncompressed AVI using any VFW codecs
