Final Cut Pro 6 - Frame Blending and Reverse Speed

Frame Blending and Reverse Speed

Duplicating frames to create slow motion can result in a strobing, jittery effect. To
minimize this, you can turn on frame blending in the Speed dialog. When slow motion
is created, frame blending uses the two frames that appear to either side of duplicate
frames and creates new in-between frames that are a composite of both. When
blended frames are inserted in place of frames that have simply been duplicated,
slow-motion clips appear to play back more smoothly. Speed changes can still play
back in real time with the Frame Blending option turned on.

Changing Clip Speed and Time Remapping



Note: While clips using frame blending can play in real time at preview quality, frame
blending on a field-per-field basis is much more processor-intensive and is only
performed when the clip is either rendered or played via a third-party video interface
with real-time hardware processing that’s capable of field blending.

You can make a clip play backward by selecting the Reverse option. Alternatively, you
can enter a negative speed setting.

Note: Frame blending and reverse speed can be applied to both constant and variable
speed clips.
