Deinterlace
Figure 30. Deinterlace settings
The deinterlace group has four radio buttons.
Auto Apply inverse telecine deinterlacing to all telecine video. Apply motion
adaptive deinterlacing to all video that is not telecine. Switch dynamically
between the two modes as the content changes. Available for NTSC video
only.
Inverse Telecine Apply inverse telecine deinterlacing to all telecine video. Perform no
deinterlacing of video that is not telecine. Available for NTSC video only.
Motion Adaptive Apply motion adaptive deinterlacing to all video.
Adjust… Click this button to display the Adaptive Deinterlace window. See Adaptive
Deinterlace window for information on using this dialog box.
Off Perform no deinterlacing of any kind.
Deinterlace settings are applied and stored per-device and are applied to all filters and pins associated
with a device.
Inverse telecine
Telecine video is NTSC video that 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 are visible.
The inverse telecine process is the reverse of telecine; it drops the redundant fields and reassembles the
video in a 24 fps progressive format. Interlacing artifacts are 100 % removed. If the video is viewed at 24
fps, you see the exact timing and sequencing that was on the original film. If the video is viewed at 30
fps, every 5th frame is repeated; however, there are 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 buttons are disabled when PAL or SECAM is selected as the video standard.
