Encoder Preset (A, B, and C)
an appliance can support multiple concurrent filters on one device if the processing per filter is light. However, only 2 or 3 simultaneously running filters can be supported if the processing load inside or outside the driver is particularly heavy.

Motion Adaptive Deinterlace
Motion adaptive deinterlace is an algorithm for deinterlacing pure video
Telecine and Inverse Telecine
Telecine video is NTSC video which was originally created on film at 24 frames per second. In the telecine conversion process, certain fields are repeated in a regular, recurring sequence. If a telecined sequence is viewed directly on a progressive screen, interlacing artifacts will be visible.
The process called “inverse telecine” is the reverse of “telecine” — inverse telecine drops the redundant fields and reassembles the video in a 24 fps progressive format. Interlacing artifacts are 100 percent removed. If the video is viewed at 24 fps, you will see the exact timing and sequencing that was on the original film. If the video is viewed at 30 fps, every fifth frame will be repeated. However, there will be no deinterlacing artifacts.
Telecine and inverse telecine only apply to NTSC video. They are not used for PAL and SECAM video. The Auto and Inverse Telecine button choices will be disabled when either PAL or SECAM is selected as the video standard.
