vf_divtc: remove this filter
Better solutions are available in vf_vapoursynth and vf_lavfi. The only user I know who used this is now using vf_vapoursynth.

@ -406,68 +406,6 @@ Available filters are:
|
||||
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.
|
||||
|
||||
``divtc[=options]``
|
||||
Inverse telecine for deinterlaced video. If 3:2-pulldown telecined video
|
||||
has lost one of the fields or is deinterlaced using a method that keeps
|
||||
one field and interpolates the other, the result is a juddering video that
|
||||
has every fourth frame duplicated. This filter is intended to find and
|
||||
drop those duplicates and restore the original film framerate. Two
|
||||
different modes are available: One-pass mode is the default and is
|
||||
straightforward to use, but has the disadvantage that any changes in the
|
||||
telecine phase (lost frames or bad edits) cause momentary judder until the
|
||||
filter can resync again. Two-pass mode avoids this by analyzing the entire
|
||||
video beforehand so it will have forward knowledge about the phase changes
|
||||
and can resync at the exact spot. These passes do *not* correspond to pass
|
||||
one and two of the encoding process. You must run an extra pass using
|
||||
``divtc`` pass one before the actual encoding throwing the resulting video
|
||||
away. Then use ``divtc`` pass two for the actual encoding. If you use
|
||||
multiple encoder passes, use ``divtc`` pass two for all of them.
|
||||
|
||||
The options are:
|
||||
|
||||
``pass=1|2``
|
||||
Use two pass mode.
|
||||
|
||||
``file=<filename>``
|
||||
Set the two pass log filename (default: ``framediff.log``).
|
||||
|
||||
``threshold=<value>``
|
||||
Set the minimum strength the telecine pattern must have for the filter
|
||||
to believe in it (default: 0.5). This is used to avoid recognizing
|
||||
false pattern from the parts of the video that are very dark or very
|
||||
still.
|
||||
|
||||
``window=<numframes>``
|
||||
Set the number of past frames to look at when searching for pattern
|
||||
(default: 30). Longer window improves the reliability of the pattern
|
||||
search, but shorter window improves the reaction time to the changes
|
||||
in the telecine phase. This only affects the one-pass mode. The
|
||||
two-pass mode currently uses fixed window that extends to both future
|
||||
and past.
|
||||
|
||||
``phase=0|1|2|3|4``
|
||||
Sets the initial telecine phase for one pass mode (default: 0). The
|
||||
two-pass mode can see the future, so it is able to use the correct
|
||||
phase from the beginning, but one-pass mode can only guess. It catches
|
||||
the correct phase when it finds it, but this option can be used to fix
|
||||
the possible juddering at the beginning. The first pass of the two
|
||||
pass mode also uses this, so if you save the output from the first
|
||||
pass, you get constant phase result.
|
||||
|
||||
``deghost=<value>``
|
||||
Set the deghosting threshold (0-255 for one-pass mode, -255-255 for
|
||||
two-pass mode, default 0). If nonzero, deghosting mode is used. This
|
||||
is for video that has been deinterlaced by blending the fields
|
||||
together instead of dropping one of the fields. Deghosting amplifies
|
||||
any compression artifacts in the blended frames, so the parameter
|
||||
value is used as a threshold to exclude those pixels from deghosting
|
||||
that differ from the previous frame less than specified value. If two
|
||||
pass mode is used, then negative value can be used to make the filter
|
||||
analyze the whole video in the beginning of pass-2 to determine
|
||||
whether it needs deghosting or not and then select either zero or the
|
||||
absolute value of the parameter. Specify this option for pass 2, it
|
||||
makes no difference on pass 1.
