Cadence Removal; Clean Cadence - Blackmagic Design BMD-TERANEXEXP12GDL Teranex Express Manual De Instalación Y Funcionamiento

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.
TIP For information on advanced clean cadence settings, refer to "Advanced Menu"
on page 43.
