Deinterlace
This option removes artifacts that the system can introduce when encoding NTSC, PAL, or
SECAM formatted video. These artifacts usually manifest as a jaggedness surrounding a moving
object.
You apply and store these filters per each device. Applies to all filters and pins associated with a
specific device. Includes four radio button options:
Off – disallows interlacing
Motion Adaptive - applies motion adaptive interlacing to all video
Inverse Telecine - applies inverse telecine deinterlacing to all telecine video
o It performs no deinterlacing of non-telecine video.
o It is available for NTSC video only.
Auto - applies inverse telecine deinterlacing to all telecine video.
o It applies motion adaptive deinterlacing to all non-telecine video.
o It switches dynamically between the two modes as the content changes.
o It is available for NTSC video only.
Telecine
NTSC video is created originally on 24-frame-per-second film. It repeats certain fields in a
regular, recurring sequence in the telecine conversion process. It also provides visible interlacing
artifacts if you view a telecined sequence on a progressive window. Telecine only applies to
NTSC video. It is not used for PAL and SECAM video. If you select PAL or SECAM as the video
standard, you disable telecine. Telecine represents the film-to-video conversion process.
Inverse telecine
Inverse telecine is the reverse of telecine. It drops redundant fields and reassembles video in a
24 fps progressive format. It removes 100% of interlacing artifacts.
When you view video at 24 fps, you see the exact timing and sequence on the original film.
When you view video at 30 fps, the system repeats every fifth frame and eliminates de-
interlacing artifacts.
Inverse telecine only applies to NTSC video. It is not used for PAL and SECAM video. If you select
PAL or SECAM as the video standard, you disable inverse telecine. The inverse-telecine filter
looks for frames added during a telecine process and removes them. This eliminates redundant
encoding and improves the quality of encoded frames.
