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. The Teranex 2D and 3D
will remove cadence automatically when converting video with a 3:2 pulldown to 24 frames per second.
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. For more information
on Clean Cadence settings, see page 20.
Power your Teranex and connect your inputs and outputs.
Setting your Input
Step 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.
Step 2. Select EMBED as the audio input format.
Setting your Output
Step 1. Press the OUT button on the control panel. All active video output buttons are illuminated blue.
Step 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.
Step 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.
Step 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.
Step 5. Press the HOME menu button, then select Video>Advanced>Clean Cadence. Use the rotary
knob or soft button to set Clean Cadence to On. The 1080i59.94 output format will now contain
a clean 3:2 cadence. Remember to set Clean Cadence to Off after completing your conversion.
Setting your Aspect Ratio
The ADJ adjustable aspect ratio button is available for custom aspect ratio settings. For more information on
aspect ratio conversion see pages 17 and 65-66. Your video output will now have a clean cadence applied.
Cadence Removal is applied automatically when converting
from an NTSC frame rate to a film frame rate. For example,
59.94fps to 23.98fps.
