FEATURES
~~~~~~~~
. The program is designed for testing of a video compression codecs 
. Allows in real-time mode to meter maximum efficiently of encoder and visually to judge the worth image quality 
. Matching more optimum VCM driver for compressing image data from your application 

System requirements
. Windows95, Windows98, Windows2000 
. CPU: Pentium-MMX or higher recommended, but not required 
. Display card with DirectX hardware support 
. DirectX 6 or higher

Testing options
~~~~~~~~~~~~~~~
Testing options dialog is accessible trough key combination CTRL+O.

. Mirror captures frame - some video codecs demand it. 

Size of the captured video frames
. Frame size - width and height of the digitized frame in pixels 
. List - choice of significance from the list 
. Window size - to set width and height equal to a current size of the window. 
. User - direct input of width and height. 

. Color mode - codecs input color format 

Video compression options - specifies the codec (compressor/decompressor) and set options specific to the selected codec. 

Choices of abort of test mode condition.
. Frames limit - maximum frames 

Expected parameters for the pending compression codeces:
. FPS - approximate expected capture speed. 
. Frames count - approximate expected capture size. 

Pending compression codeces use this information for the definition of the compression and images quality. These values adjust experimentally.
