Alternative mode 2 (Video Mixing Renderer 9): This mode uses hardware
deinterlacing of modern graphics cards together with DirectX9. Make sure that
you've installed the latest graphics card drivers and the card is compatible with
DirectX9. This mode works better than the standard mode (Overlay Mixer) only
for a few graphics card models.
Standard renderer: The DirectShow standard renderer is used for viewing.
Image formation in Vertical Blank Intervals (VBI)
The image formation takes place in the vertical blank intervals of the monitor
signal (or the connected TV signal). This helps avoid image interruptions.
Warning: Because of the necessary waiting time on the next VBI, this process
adds significant computation time!
You can deactivate this option for digital displays such as TFT monitors. In
"Overlay" mode, image formation occurs exclusively via VBI.
Acceleration for high-resolution MPEG2 files
This option can be selected only in the "Hardware acceleration (Direct 3D)"
video mode and indicates that videos in MPEG-2 format will be processed
directly from the graphics card GPU. Depending on the graphics card
performance, an improvement of up to 300% can be achieved!
De-interlacing
The DirectShow modes "Overlay mixer" and "Video mixing renderer 9" enable
activation of hardware de-interlacing for the graphics card. For general
information about de-interlacing and the options "Top/bottom field first", please
read the corresponding article "De-interlacing (view page 395)" in the manual.
Comparison image in source monitor for editing effects in the Media Pool
If this option is activated, the "Selected objects without effects" comparison
mode will be automatically activated when switching into the Media Pool
effects, and will be automatically deactivated when the mode is exited. This
serves to compare the original and edited image.
This automation will be suppressed if the option is deactivated.
