5.5 Convert-Ch1 and Ch2
The Convert-Ch1 and Ch2 screens enable control of motion processing and improve the
conversion performance of stationary content.
l
5.5.1 Up Conversion
•
Clean Edge Upconversion:
Enables the Texture Adaptive Upconversion (TAU)
process which helps to adapt away any horizontal ringing (vertical edges).
5.5.2 Motion Processing
•
Still Process
: Uses powerful motion detection techniques to extract the maximum
resolution from interlaced sources while format or standards converting (where fitted).
The benefits of this processing are prominent on static logos and computer-generated
overlays.
•
Enhanced Still
: Adds field motion detection to still processing. This reduces artifacts
on moving repetitive patterns.
•
Enhanced Film Mode
l: Applies an aperture with full progressive frequency response
where the input is film transported by an interlaced video rate input, with cadence
enabled (see section 5.5.3).
•
Enhanced De-interlace
: Replaces missing lines with a gradient between the
previous and following lines. This control improves the appearance of de-interlaced
images and is useful when dealing with complex shapes.
•
Clean Cut
: Prevents temporal filtering across a cut in scenes, which can result in
several frames either side of the cut being a mix of the two different scenes.
Note:
The Convert-Ch2 screen is only applicable to the IQUDC31 and IQUDC33.
