Remove 3:2 pulldown

Removes 3:2 pulldown from the input footage.

If you’re using footage that was originally film but was converted to video, you may want to use the Remove 3:2 pulldown node when importing the footage to Nuke. This allows you to convert the footage to its original state (24 fps non-interlaced film) before adding effects to it. If you later want to render the footage back to video again, you can use the Add 3:2 pulldown node to reintroduce 3:2 pulldown.

Inputs and Controls

Connection Type	Connection Name	Function
Input	1	The image sequence to remove 3:2 pulldown from. For example, footage that was originally film but was converted to video.

Control (UI)	Knob (Scripting)	Default Value	Function
User Tab
phase	phase	0	The 3:2 pulldown process results in: • three whole frames that contain two fields from the same film frame, and • two split-field frames that contain fields from two different film frames. The two split-field frames are always adjacent to each other. Phase is the point at which the two split-field frames occur within the first five frames of the footage, relative to your first input frame. The value here should match the phase used when 3:2 pulldown was added.
invert field dominance	field_dom	disabled	Video frames are usually divided into two fields. Each field contains only half of the image information, drawn as horizontal scan lines: • The first field of a frame contains every other scan line. • The second field of a frame contains the remaining scan lines. When both fields are displayed in rapid sequence, they appear to produce a normal, complete frame. Invert field dominance determines which field is displayed first: • When enabled, the odd lines come first. • When disabled, the even lines come first.
