Frame Blending - Time Compressing and Stretching
Made Good
It used to be that any variable speed changes inevitably resulted in a loss of
quality and smoothness in your altered footage. The usual method of increasing
or decreasing a clip's playback frame rate was to either duplicate frames
(decreasing frame rate) or drop frames (increasing frame rate). The result was
usually stuttery and jumpy footage - a ruination of the original footage.
Frame Blending alleviates this stuttering and jumpy footage problem by
enabling a process where adjacent frames are mixed together to create
smoother transitions from duplicated frames for better slo-mo, or multiple
frames are mixed together, rather than dropped,
resulting in more natural, motion blurred, rapid
motion. Frame Blending is applied by first
activating the Frame Blending button in the
Timeline Window (seen at left), then checking the
box under the Switches Column (seen below).
Frame Blending works on three modes of footage Frame Rate changes:
13
Interpret Footage - Frame Rate setting.
14
Time Stretch - Constant Speed Change.
15
Time Remapping - Variable Speed Change.
