Merge
(clip1, clip2, float weight=0.5)
(clip1, clip2, float weight=1.0)
MergeChroma
MergeLuma
(clip1, clip2, float weight=1.0)
These filters make it possible to merge pixels
(or, for YUV clips only, just the luma or chroma) from one videoclip
into another. There is an optional weighting, so a percentage between the two clips
can be specified. Merge
is present in v2.56.
clip1 is the clip that has the appropriate data merged INTO (based on
which filter you use). In the case of
MergeLuma
or
MergeChroma
, that means that the OTHER channel
(chroma or luma respectively) is completely untouched.
clip2 is the one from which the pixel data must be taken. In
MergeChroma
, this is where the Chroma will be taken from, and
vice-versa for MergeLuma
. It must be the same colorspace as clip1; i.e. you cannot merge from a YV12 clip into a YUY2 clip.
The weight defines how much influence the new clip should have. Range
is 0.0 to 1.0, where 0.0 is no influence and 1.0 will completely overwrite the
specified channel. The default is 0.5 for Merge
and 1.0 for
MergeChroma
and MergeLuma
. The filter will be slightly
slower when a weight other than 0.0, 0.5 or 1.0 is specified.
Also see here for the resulting clip properties.
