We're all probably in a encoding cycle

Well, sorry to spoil yor encode, but go ahead and break it
I've added STMedianFilter(10, 50, 0, 0, 10, 50). The theory behind this is that I turned on ONLY the "Spatial" portion of the filter, and left the "Temporal" functions disabled. The result is to filter ONLY spatial information, which is only intra frame (adjacent pixels in a frame) as opposed to inter frame temporal filtering, which is reference to adjacent frames. The result is a file size reduction, with identical maintained quality, and no image streaking as normally seen with heavy temporal smoothers. The file size reduction is ~160KB to 180KB per minute of video

hi friends

i'm testing the new script ...

LegalClip()
GripCrop( X, Y )
GripSize(resizer="BicubicResize")
STMedianFilter(10, 50, 0, 0, 10, 50)
unfilter(50,50)
temporalsmoother(1,2)
mergechroma(blur(1.5)
mergeluma(blur(0.3))
GripBorders()
LegalClip()

the image is fantastic but is very very slow!!!
TMPGEnc:
left 05:47x to end with CQ: 66,127 for only 280Mb final size!
(from MovieStacker script & ToK values.)

(using Athlon xp 2000+ , Maxtor 60G 7200rpm , 512Mb Ram)

any

ps:
why the number "8" appears like in the script posted???


thanks in advance!

Hi jorel,

The line: STMedianFilter(10, 50, 0, 0, 10, 50) will slow down the encoding somewhat, but the file size will drop drastically. If you get good quality without it, then just drop the filter. But for long movies or action movies, the filter will help increase the CQ a lot!.

The show when you use an 8 followed by a ) like this () because it's the emoticon characters. If you want 8 to show, use spaces. Like this: ( 8 )

Hey jorel, are you sure you have STmedianfilter in the right place in your script? That looks a little backwards to me... shouldn't the filter come later, say after mergeluma??

NOOOOOOOOOOO Yet more testing!!!!!!! "Just when you thought it was safe to go back into the water..."

Anyways, I decided to run my usual comparison test using the latest optimal script with and without STMedianFilter(10, 50, 0, 0, 10, 50), and also once using SpaceDust() instead of STMedianFilter. The clip is a fullscreen 1:45 trailer, encoded @ 544x480 and 29.97fps (as my dvd player requires), on a P4 2.26GHz with 1GB ddr-ram.

Results:
Code:
Script w/out STMedianFilter= 17.48MB;  encoding time= 6:16

Script w/ STMedianFilter= 16.78MB;  encoding time= 6:54

Script w/ SpaceDust instead= 16.86MB;  encoding time= 6:28
Viewed on my standard TV, I couldn't see too much difference between using STMedianFilter and not using it, but I do think there may have been a very small decrease in detail with it (but after doing so much testing over the past month or so, it may also simply be that I'm hesitant to more script changes at this point...or maybe it's all in my head! ). Using STMedianFilter did seem to look slightly better than SpaceDust though to me (plus gave a tad more compression), so personally if I'm ever in need of some extra compression on those longer movies, I'll probably turn to STMedianFilter first and foremost. So thanks once again kwag!

so does the new filter have to be loaded or is it already written into avisynth ? (stmedian)

Also will it help put a 102 minute movie on one KVCDx3 disc ?

hi LadyMiles

the filter have to be loaded (download from doom9)

and i think that 102 minutes in one KVCDx3 is possible!
(audio 128,if don't 112)
