mfToons

[Prim3]

Hey, I've been looking around and I can't seem to get mfToons to work properly.

There's this thread: http://forum.doom9.org/showthread.php?t=52066

And, then theres this:http://forum.doom9.org/showthread.php?t=53364

I'm kind of confused on what to use and how to use with what requirements I need. If it's possible, can somebody point me to the right direction? And, I just want mfToons for quality. Speed is never a problem for me.

Thanks,
Prim3

Since most people (that I've talked to) use mf/vmtoon for line darkening and just pretty much don't use the sharpening part, why not try something like Fast Line Darken.

And if you want to use mftoons, try vmtoons since it's basically like the newer version of mftoon. There's also toon v0.82 (latest one right now) here. (http://forum.doom9.org/showthread.php?t=125128) There are several different versions in that thread, don't use the one in the OP, scroll down for latest one some where.

I have yet to try toon and compare it to vmtoon, and fast line darken (on my to do list, little busy right now though)

For fast line darken try:
FastLineDarkenMOD(thinning=0, strength=60)

Of course you'll have to adjust the parameters to suit your taste.

# FastLineDarken 1.3x MT MOD #
##############################
#
# Written by Vectrangle
# Didée: - Speed Boost, Updated: 11th May 2007
#
# * requires mt_masktools v2
# * requires yv12 input
#
# Usage is FastLineDarkenMOD(strength, luma_cap, threshold, thinning),
# named parameters are supported eg FastLineDarken(thinning=0)
#
# Note that you must import this avs into your script using import("...\FastLineDarken.avs")
#
# Parameters are:
# strength (integer) - Line darkening amount, 0-256. Default 48. Represents the _maximum_ amount
# that the luma will be reduced by, weaker lines will be reduced by
# proportionately less.
# luma_cap (integer) - value from 0 (black) to 255 (white), used to stop the darkening
# determination from being 'blinded' by bright pixels, and to stop grey
# lines on white backgrounds being darkened. Any pixels brighter than
# luma_cap are treated as only being as bright as luma_cap. Lowering
# luma_cap tends to reduce line darkening. 255 disables capping. Default 191.
# threshold (integer) - any pixels that were going to be darkened by an amount less than
# threshold will not be touched. setting this to 0 will disable it, setting
# it to 4 (default) is recommended, since often a lot of random pixels are
# marked for very slight darkening and a threshold of about 4 should fix
# them. Note if you set threshold too high, some lines will not be darkened
# thinning (integer) - optional line thinning amount, 0-256. Setting this to 0 will disable it,
# which is gives a _big_ speed increase. Note that thinning the lines will
# inherently darken the remaining pixels in each line a little. Default 24.
#
# Changelog:
# 1.3 - added ability to thin lines, now runs much slower unless thinning=0. Changed the defaults (again)
# 1.2 - huge speed increase using yv12lutxy =)
# - weird darkening issues gone (they were caused by yv12layer)
# - show option no longer available due to optimizations. Use subtract() instead
# 1.1 - added luma_cap option
# 1.0 - initial release
#
