- Advanced Film Mode (AFM)– Another term for Inverse 3:2 pull-down. In this mode
the 3:2 cadence is being detected and Pixel by Pixel Motion Adaptive De-Interlacing is
being applied. Video with 3:2 eld sequences are processed with the built-in Adaptive
Film Mode controller. The eld sequence is rst detected by examining the eld motion
values and once a eld sequence is identied, the corresponding lm mode processing
is applied. Most DVD’s and VHS movies fall into this de-interlacing process.
- Static Mesh (SM): Static mesh involves the meshing of odd and even elds (without
considering temporal effect) to form the output frame. Static Mesh is best used for
static images when the elds can be simply meshed together to create the progressive
frame. This process is used for fully static images (such as a PAUSE in DVD, the
image appears static)
- Vertical Temporal (VT): Used when there is motion from one eld to the next. This is
also used to de-interlace normal video where no extra elds have been added by a 3:2/
2:2 pull-down process. This is simple de-interlacing. A form of static de-interlacing that
examines and lters both vertically across several video lines and temporally from one
or more adjacent video elds. This approach reduces icker and increases resolution
because of input from adjacent elds. Edge effects still exist but are much less evident
than other static de-interlacing methods.
- Graphics (GFX): This is the process for 2:2 sequence de-interlacing. Most PAL DVD
and VHS movies are in this category. Some NTSC computer animation and cartoons
also behave in 2:2 sequence when converted to NTSC video.
Auto – Setting to AUTO mode will allow the UpConverter to examine the video content and
automatically apply the de-interlacing method best suited at that moment. Normally DVD or
VHS movies are either in 3:2 or 2:2 except in the footage where it may be video. However,
there are cases where a mixing of 3:2/2:2 and video. TV will mostly be in video except
when it’s playing movie. The most complicated eld sequences that we encounter are TV
commercials and MTV. In these 2 cases there are always a mixture of video and lm and the
editing makes it more complicated. In Auto mode you may see the indicator lights move from
AFM to VT or GFX depending upon the video content.
