noise reduction question

[MCD]

In tmpg,under noise reduction filter,what does checking or unchecking the box that says " high quality mode" other then increasing the encode time do for ya??

not a whole lot of diff really ..

I believe the technical details is that NR in TMPGenc is a combo of temporal and spatial softening. HQ runs the spatial soften twice I believe once before to improve temporal and once after to try and fix and posterization or ghosting that might occur.

This is my understanding.

Personally I have given up on TMPGenc NR and have moved on to AVIsynth with a combo of FluxSmooth and PeachSmoother that do a bang up job without distorting the picture with ghosting posterization or softening. Much faster than TMPGenc NR too.

Snow,

Mind giving us some settings ??

dont use it !!!
it just gonna take alot more time to encode the movie , and the reuslt isnt diffrent form the original avi movie !!

Take for eample a recent widescreen analog capture.

GuavaComb is from GuavaComb.dll helps do post processing for color seperation ( rainbows )
Telecide, Decimate are from Decomb.dll
FluxSmooth are from FluxSmooth.dll
PeachSmoother is from PeachSmoother.dll

Search the avisynth , google, forum.doom9.org if looking for those plugins.


SegmentedAVISource("takenp10.avi").Crop(0,58,720,3 52)

GuavaComb(mode="NTSC",MaxVariation=10,Recall=88) # much stronger and I sometimes get color "stuck" from previous frames

Telecide(guide=1)
Decimate()

FluxSmooth(7,5) # slightly less temporal than the default
PeachSmoother(NoiseReduction = 40, Stability = 18, Spatial = 80) # tweak to your prefrence, this really helps to "lock in" stable but slightly noisy areas of the image.

snowmoon -- i have used v-dub for awhile when required and want to get in to trying avisynth if it will work in my applications -- do you set color output to rgb24 if you are frame serving to tmpgenc and yuy2 if frame serving to cce based on what thier input is ? have you ever used AVSGenie gui ? ..

snow,

How good is the telecide function, esp compared to tmpg's ivtc routine ? Would you mind describing your process for IVTC ? Sorry for all the questions, I've been having some minor issues with IVTC routines lately.
