Nuke

During a recent forum conversation at www.fxphd.com someone mentioned some problems they were having with the default Add24p and Remove 24p nodes in Nuke.  I went to try and answer the concern, only to find by way of experimentation that the default nodes really do overcomplicate the whole thing and are mathematically incorrect to boot.

Taking my cue from the Shake filein node's 24<->30 conversion tools I decided to create a much more accurate Telecine / Inverse Telecine operation in Nuke.  The results are slightly faster than the default nodes, have tested out with Shake and seem to work seamlessly with the settings in that program, and don't generate the registration errors and temporal distortions found when working with the default nodes on longer sequences.

Note that these work with old school 2:3 pullup/pulldown terminology, so all you have to do is find the cadence and the field dominance order and you're pretty much done.  For obvious reasons it won't work with 2:3:3:2 (ie 24p Advanced), although in practice I think this should still be fairly rare at the compositing workstation level.  If demand justifies, however, I'd be happy to develop a version for the 24pA world if you shoot me a line.

Installation instructions (including how to add to the Menu in 4.x or the Toolbar in 5.x) in the README in the ZIP.

Enjoy.
