Select “New (smaller)” or “Same (faster)” to specify the kind of file you want to create:
• New (smaller): Creates a new media file that does not contain the extra frames
introduced by the pull-down. The new file is about 20 percent smaller than before, but
this method is slower. Regardless of whether the original file was reference or
self-contained, this method creates a self-contained file. (See
Self-Contained and Reference Media Files
for more information.)
• Same (faster): Modifies the current media file so that the extra frames are not visible
to the editing system, but the data is not removed from the file. This process is faster
but does not reduce the size of the file. The resulting file is self-contained if it was
originally self-contained, or reference if it was reference.
When New is selected,
“Check for cadence
discontinuities” is on.
For Same, you can
deselect it to speed
up processing.
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.

Click OK to start the pull-down removal process.
If you selected the New file option, you are asked to give the new reversed clip a name
and location. If the original clip was connected to a database record, the new reversed
clip replaces its connection to the record (regardless of whether or not the new clip
overwrites the old clip).
