Const Point Display
When Const Point Display is enabled, the frame considered as the Out point is toggled
to the frame at which it becomes black, or the last frame on disk.
FileIn Trim
The FileIn Trim option controls what happens when you drag the outPoint handle and
right looping handle past each other (first image). With FileIn Trim off, Control-dragging
a timing handle past a looping handle collapses the looping portion of the clip as the
clip’s total duration is changed.
When FileIn Trim is turned on, you can Control-drag a timing handle past a looping
handle. This is useful if you want to keep the original frame range of the clip as a
reference.
Reversing a Clip
To reverse a clips so that it plays backwards, simply switch the firstFrame and lastFrame
values in the Timing tab of the clip’s FileIn node. This cannot be done with QuickTime
clips, because QuickTime clips do not have firstFrame and lastFrame parameters.
