Dissolve
(clip1, clip2 [, ...], int overlap, float "fps")
Dissolve
is like AlignedSplice
, except that the clips are
combined with some overlap. The last overlap frames of the first video
stream are blended progressively with the first overlap frames of the
second video stream so that the streams fade into each other. The audio streams
are blended similarly.
The fps parameter is optional, default=24.0, and provides a reference for overlap in audio only clips. It is ignored if a video stream is present. Set fps=AudioRate() if sample exact audio positioning is required.
The term "dissolve" is sometimes used for a different effect in which the transition is pointwise rather than gradated. This filter won't do that.
Also see here for the resulting clip properties.
Changes:
