Third-generation pulldown reversal (inverse telecine) filter,
capable of handling mixed hard-telecine, 24 fps progressive, and 30
fps progressive content.
@ -3941,6 +3941,18 @@ Setting the sb (strict breaks) option to 1 will reduce the chances of
pullup generating an occasional mismatched frame, but it may also
cause an excessive number of frames to be dropped during high motion
sequences.
Conversely, setting it to -1 will make pullup match fields more
easily.
This may help processing of video where there is slight blurring
between the fields, but may also cause there to be interlaced frames
in the output.
The mp (metric plane) option may be set to 1 or 2 to use a chroma
plane instead of the luma plane for doing pullup's computations.
This may improve accuracy on very clean source material, but more
likely will decrease accuracy, especially if there is chroma noise
(rainbow effect) or any grayscale video.
The main purpose of setting mp to a chroma plane is to reduce cpu load
and make pullup usable in realtime on slow machines.
