Cadence Removal
Cadence Removal involves the removal of the 3:2 pulldown sequence. 3:2 pulldown is applied
when a telecine transfers film at 24 frames per second to video at 59.94 fields per second.
Your Teranex processor will remove cadence automatically when converting video with a 3:2
pulldown to 24 frames per second.
Cadence Removal is applied automatically when converting from an NTSC
frame rate to a film frame rate. For example, 59.94fps to 23.98fps.
Clean Cadence
Clean Cadence in the Teranex 2D and 3D removes broken, non standard and mixed cadences
and creates a clean 3:2 pulldown. A 3:2 cadence is found in 59.94 program material, so clean
cadence is only available when working with 59.94 frame rates. In this example, we will perform
a cross conversion to clean the cadence on a 1080i59.94 video signal via SDI with
embedded audio.
Power your Teranex and connect your inputs and outputs.
Setting your Input
1 Press the ‘in’ button on the control panel and select ‘SDI’ video. Teranex will display
the input video on the LCD, automatically detect the input format and illuminate the
corresponding buttons.
2 Select ‘embed’ as the audio input format.
Setting your Output
1 Press the ‘out’ button on the control panel. All active video output buttons are
illuminated blue.
2 Press the ‘1080’ button. The button is now illuminated green. Select the ‘I’ button for
interlaced output and the ‘59.94/60’ button to set the frame rate. These buttons will
also illuminate green.
3 Using the soft menu buttons, select ‘change’. The output video is now displayed on the
LCD and sent to all output connectors. The buttons will also illuminate blue to confirm
your settings.
4 In this example aspect ratio is locked to 16:9. However, if you wish to adjust it manually
press the ‘adj’ button and adjust your aspect ratio settings using the soft menu
buttons and LCD.
