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.
Telecine video - 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 will be visible.
Inverse Telecine (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 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 buttons will be disabled when PAL or SECAM is selected as the video
standard.
Motion adaptive deinterlace - An algorithm for deinterlacing pure video (non-telecine) content. It
detects which portions of the image are still, and which portions are in motion, and applies different
processing to each.
Currently Using
These indicators allow you to see the current algorithm. These are
not
control buttons – they are
read-only indicators. They are mainly useful in Auto Mode, to indicate which algorithm – Inverse
Telecine or Motion Adaptive – is currently being applied. They are also useful in Inverse Telecine
mode to show whether telecine content is present and the Inverse Telecine algorithm is being
applied.
The mode currently in use is marked by a green arrow (Figure 29). A mode that is possible under
current control settings but not currently in use is marked by a dark grey arrow. A mode that is not
available with the current control settings is marked by a pale outline arrow
Figure 29. Currently Using
With inverse telecine enabled, when telecine content is detected, the five Cine Phase dots show
whether the 3:2 pull down sequence is shifting. If it is shifting, the green marker will shift. This will
happen in mixed telecine/video content, and also in content that was converted to telecine and
