Select “New (smaller)” or “Same (faster)” to specify the kind of file you want to create:
 New (smaller): Creates a new clip 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 referencing or
self-contained, this method creates a self-contained file. (See “
Between Self-Contained and Referencing Clips
” on page 126 for more information.)
 Same (faster): Modifies the current clip 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 referencing if it was referencing.
About cadence discontinuity checking: While removing the pull-down, Cinema Tools
looks for breaks in the pull-down cadence and if any breaks are found, it adjusts the
processing to accommodate those discontinuities. A cadence discontinuity might
occur when a recording is stopped and then starts 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 box 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).
If you choose New, the file
will be smaller. If you choose
Same, the processing will
be faster.
When New is selected,
“Check for cadence
discontinuities” is on. For
Same, you can deselect
it to speed
up processing.
