i've asked this question at doom9 but nobody answered.

Edeen is the only one i have tested so far.

Thanks

You question isn't very smart.

Blur( 1.58 ) will give you an extreme compression, but an image unwatchable.

So ?

unfilter(-100,-100)
extreme compression but unwatchable too!

Best compression ever :
Code:
Blankclip(length=last.Framecount)
I assure you that you can put 10 hours of video on a single CD with this

ok. one more thing. i'm encoding resident evil with my avisynth script like this.

LoadPlugin("C:\unzipped\filter/deen_25_dll_20030119[1]/deen.dll")
LoadPlugin("C:\unzipped\filter/GripFit_YV12[1]/grip.dll")
LoadPlugin("C:\unzipped\filter\UnDot[1]/undot.dll")
LoadPlugin("C:\unzipped\filter\dctfilter_25_dll_20 030221[1]/DCTFilter.dll")
LoadPlugin("C:\unzipped\filter\Sampler-0.2a[1]/Sampler-2.5.dll")


AviSource("c:/unzipped/movies/resident evil.avi")
GripCrop(544, 480, overscan=1, source_anamorphic=false)
GripSize(resizer="BilinearResize")
Undot()
Deen()
DCTFilter(1,1,1,1,1,1,0.5,0)
GripBorders()

, but somehow this is faster than just encoding the movie without filters or anything.

Can filters also give a speed gain?

sorry, if that is a stupid question. the only filter i read about with a speed gain was TemporalCleaner.

by 'speed gain' you mean encoding time right? Each filter you add into the chain will increase the encoding time. The fastest speed would be to encode at a lower resolution (like 352x240) with no filters.

yeah i mean encoding time. but it was only faster when i put it on system(video+audio). So i guess Elementary Stream Video takes longer.

For sure not. Encoding audio with TMPGENC takes 15% more time.

my TMPGEnc is just messed up then. because i put it on with just the AVI File and set it to es(video), and it said 6 hours. then i put it on system(video+audio) with an avisynth script and it said 4:36 hours. so whatever, who cares.

If you do a resizing in your avisynth script that is not dfone in your test with the avi directly, for sure the time is different !

Why use a script ? For doing both test you can use directly the avi. and toggle by hand the encoding mode from ES to System.

Note: I care to not giving false informations to people reading us
