6.4.7.1
Clean cut
Clean cut processing detects scene changes and prevents interpolation across the cut. Only
permitted if film cadence is off.
Default =
Off
.
6.4.7.2
Film mode
Use
Film mode
if input is interlaced (1080i or 525 or 625) and contains film-originated
content. This adjusts the conversion aperture to give maximum vertical bandwidth.
Default =
Off
.
6.4.7.3
Input Cadence
The Input cadence menu allows the user to define any cadence associated with the input
video.
Enable
If the input content is film-originated, or simulates film-originated content,
Enable
should be
set to
On
. Otherwise, it should be set to
Off
.
Default =
Off
.
Example 1:
Input UHD 59p (with embedded 3:2 cadence), Output 1080 23p,
59 Cadence
set to
2:3
.
Input frame sequence: A, A, B, B, B, C, C, D, D, D …
When cadence is
On
the output frame sequence will be: A, B, C, D …
When cadence is
Off
the output will be a linear frame rate conversion.
Example 2:
Input UHD 50p (with embedded 2:2 cadence), Output 720 25p
Input frame sequence: A, A, B, B, C, C, D, D …
When cadence is
On
the output frame sequence will be: A, B, C, D …
When cadence is
Off
the output will be a linear frame rate conversion.
59 cadence
If the input is film-originated and its frame rate is 59.94Hz, then the cadence should be set as
either:
•
2:3
(default)
•
2:2
(psf)
2:3
When set to
Automatic
(default) the input cadence will be determined by the cadence
detection circuit. This feature is useful when the source material contains mixed
cadences.When set to
Input timecode
, the user defines the relationship between timecode
and the 2:3 sequence. This feature is useful when the source material contains known
continuous 2:3. This setting removes any uncertainty that may be associated by use of the
sequence detector (automatic mode).
Note:
This mode is relevant only for film originated content where the cadence is carried in an
interlaced format. Where film-originated content is carried in a progressive format, Film
mode should not be used.
