Frame Interpolation Settings
Frame Interpolation Type box Select which type of interpolation to use to blend timewarped frames.
Different settings appear below depending on the type selected.
Description:Type:
When mixing frames, you are combining multiple frames together to create one blended
frame using an additive mix. Each result frame is a blend of an equal number of frames
from both sides of the given frame.
Mix
With Trails blending, you have more control than in a simple mix. You can blend the
frames before and after a given frame by different amounts. Do this to create a trail that
Trails
comes before or after any motion in the clip. You can also set the amount of fall-off for
the blend so that the trail fades away completely, partially, or not at all.
Motion estimation blends frames with subpixel accuracy, and is well-suited for particularly
challenging timewarps. Motion estimation is good for processing slow-motion, constant,
Motion
or variable speed timewarps of interlaced and progressive material. It is particularly good
for material that introduces artefacts or for which you cannot get satisfactory results using
Trail or Mix values.
Sample Mode box Select whether the interpolated position of the timewarp is set in relation to the beginning,
middle or end of each frame or field. Available for Mix and Trails types.
Mix Amount field Displays the mix value for the timewarp. Each result frame is a blend of an equal number
of frames from both sides of the given frame. Editable.
Pre Amount field Displays the value to mix the frames that precede the current frame with the current
frame. Editable.
Pre Weight field Displays the fall-off value for the pretrail. When the value is 0%, the image in the current
frame is at 100% intensity and the first image in the trail is at 0% intensity. When the value is at 100%,
there is no fall-off. Editable.
