@section pullup
|
||||
|
||||
Pulldown reversal (inverse telecine) filter, capable of handling mixed
|
||||
hard-telecine, 24000/1001 fps progressive, and 30000/1001 fps progressive
|
||||
content.
|
||||
|
||||
The pullup filter is designed to take advantage of future context in making
|
||||
its decisions. This filter is stateless in the sense that it does not lock
|
||||
onto a pattern to follow, but it instead looks forward to the following
|
||||
fields in order to identify matches and rebuild progressive frames.
|
||||
|
||||
The filter accepts the following options:
|
||||
|
||||
@table @option
|
||||
@item jl
|
||||
@item jr
|
||||
@item jt
|
||||
@item jb
|
||||
These options set the amount of "junk" to ignore at the left, right, top, and
|
||||
bottom of the image, respectively. Left and right are in units of 8 pixels,
|
||||
while top and bottom are in units of 2 lines.
|
||||
The default is 8 pixels on each side.
|
||||
|
||||
@item sb
|
||||
Set the strict breaks. Setting this option to 1 will reduce the chances of
|
||||
filter 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 filter 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.
|
||||
Default value is @code{0}.
|
||||
|
||||
@item mp
|
||||
Set the metric plane to use. It accepts the following values:
|
||||
@table @samp
|
||||
@item l
|
||||
Use luma plane.
|
||||
|
||||
@item u
|
||||
Use chroma blue plane.
|
||||
|
||||
@item v
|
||||
Use chroma red plane.
|
||||
@end table
|
||||
|
||||
This option may be set to use chroma plane instead of the default luma plane
|
||||
for doing filter'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 @option{mp} to a chroma plane is to reduce CPU
|
||||
load and make pullup usable in realtime on slow machines.

||||
