.IPs "mp (metric plane)"
This 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.

.I NOTE:
Always follow pullup with the softskip filter when encoding to ensure
that pullup is able to see each frame.
Failure to do so will lead to incorrect output and will usually crash,
due to design limitations in the codec/\:filter layer.

.B tele_src and tele_dest
Enables arbitrary telecining using Donand Graft's DGPulldown code.
You need to specify the original and the desired framerate and the
muxer will make the video stream look like it was encoded at
<tele_dest> frames per second.
It only works with MPEG-2 video when the input framerate is smaller
than the output framerate.
Example of PAL to NTSC telecining: tele_src=25,tele_dest=30000/1001.
