11.4.2 Input Cadence
Input Cadence enables you to define any cadence associated with the input video.
•
Film Cadence:
Enables the processing of film-originated content transported by a
cadence.
•
59 Cadence:
For standards with a field rate of 59 Hz and with cadence enabled, you
can choose either 2:2 or 2:3 (psf).
Note: Standards with field rate of 50 Hz and with cadence enabled are interpreted as
2:2.
•
2:3 Source:
Selects whether a 2:3 cadence is determined automatically or derived
from the input timecode.
•
Automatic:
The cadence detection circuit automatically detects the cadence.
This is useful when the source material contains mixed cadences.
•
Input Timecode:
Defines the relationship between timecode and the 2:3
sequence. This is useful when the source material contains known, continuous
2:3.
•
2:3 Start Hour:
Sets the starting hour for the timecode (when 2:3 Source is set to
Input Timecode). The adjustment range is from hour 0 to hour 23 in one-hour steps.
11.4.3 Output Cadence
Output Cadence enables you to define the required cadence of the output video.
•
Film Cadence:
Enables the cadence of the output content.
•
59 Cadence:
For standards with a field rate of 59 Hz, you can choose either 2:2 or 2:3
(psf) cadence generation.
Note: Standards with field rate of 50 Hz are interpreted as 2:2.
•
2:3 Source:
Selects whether a 2:3 cadence is free-running or derived from the output
timecode.
•
Free Run:
In Free Run mode the output 2:3 cadence is undefined. The output
will have continuous 2:3, but may vary from conversion to conversion.
•
Output Timecode:
Defines the point at which the 2:3 sequence starts relative to
timecode.
•
2:3 Start Hour:
Sets the starting hour for the timecode (when 2:3 Source is set to
Output Timecode). The adjustment range is from hour 0 to hour 23 in one-hour steps.
