There are two fields per interlaced frame, odd and even. Bob 0 is for Field 0 (even) and Bob 1 is for
Field 1 (odd). If the signal coming in is progressive, these settings have no effect.
Clicking Advanced forces the advanced motion-adaptive algorithm to deinterlace incoming video.
Telecine and inverse telecine
The dialog box allows you to enable or disable Inverse Telecine. When Inverse Telecine is enabled,
the following options are available:

Auto-detect Telecine Source

Enable Frame Resync

Resync Interval
Telecine video is NTSC video originally created on movie film at the industry-standard 24 frames-
per-second rate. Since standard NTSC video has a near-30 frame-per-second rate, in the telecine
conversion process from 24 frames to 30 frames-per-second, certain fields are repeated in a regular,
recurring sequence. If a telecined sequence is viewed directly on a progressive screen, as is usually
the case, and you stream video to a computer screen, interlacing artifacts will be visible.
The process called Inverse Telecine is the reverse of Telecine. Telecine drops the redundant fields
and reassembles the video into a 24 frames-per-second progressive format. Interlacing artifacts are
100 percent removed. If the video is viewed at 24 frames-per-second, you will see the exact timing
and sequencing that was on the original film. If you view the video at 30 frames-per-second, every
fifth frame is repeated; however, no deinterlacing artifacts exist.
Telecine and inverse telecine are not used for PAL video. The Auto and Inverse Telecine buttons will
be ignored when PAL or any HD mode is selected as the video standard.
The Deinterlace tab has the following controls:
Pin Type The drop-down list has three choices (see Capture and preview pins ).
