Apple Cinema Tools 4 - Manual (Page 223)

• Same (faster): Modifies the current clip files so that the extra frames are not visible to
the editing system, but the data is not removed from the files. This process is faster
but does not reduce the size of the files. The resulting files are self-contained if they
were originally self-contained, or reference if they were reference.
For Same, you can
deselect “Check for
cadence discontinuities”
to speed up processing.
For New, selecting Keep
Originals saves the
original clips in a folder.
If you select New,
the file will be smaller.
If you select Same, the
processing will be faster.
If you selected “Same (faster),” you can choose whether Cinema Tools checks for cadence
discontinuities.
While removing the pull-down, Cinema Tools looks for breaks in the pull-down cadence.
If any breaks are found, it adjusts the processing to accommodate those discontinuities.
A cadence discontinuity might occur if a recording was stopped and then started again
at another point in the five-frame sequence.
Checking for cadence discontinuities is more time-consuming for the Same file option
than it is for the New file option, so if you select “Same (faster),” you can deselect the
“Check for cadence discontinuities” checkbox for the fastest possible processing.
Note: If this checkbox is deselected and cadence discontinuities exist in the clip, or if the
cadence changes from 2:3:3:2 to 2:3:2:3 (or any other pattern) in the middle of a clip
because the settings were changed during the recording, reverse telecine cannot be
properly performed on the clip.
6 Click OK to start the pull-down removal.
After the process is complete, the following occur:
• If you selected “New (smaller),” for each clip in the folder, a new clip with the same
name is created and placed in a Cinema Tools–created subfolder named Reversed. If
you selected Keep Originals, the original files are placed in a Cinema Tools–created
subfolder named Originals. If you selected “Same (faster),” the new versions of the clips
replace the old versions, in their original folder.
