Figure 27. Mode
The Mode group (Figure 27) selects the two main functional modes of the driver – PostProcessing
Mode and Direct Mode – as well as the Quality/Throughput tradeoff for PostProcessing Mode.

PostProcessing - The following processing steps can be applied to the video:
o
Deinterlace or inverse telecine
o
Gamma correction and software hue correction
o
Logo (watermark)
o
NTSC Closed Caption rendering

Deinterlace/inverse telecine and gamma/hue adjustment are applied to all filters on the device and
must have the same settings for all filters.

Crop, logo, and caption settings can be different for each pin of each filter, and the driver saves
settings between sessions separately for each filter and pin.

Video size, color format, and frame rate can also be different for each pin, but it is the responsibility
of the application to save these settings.
Direct
When Direct mode is selected, processing by the driver is minimized. The processing steps named
above – deinterlace/inverse telecine, gamma, logo, and caption rendering – are not available.
