Sorry Typo!
What I'm using is LumaBlur 0.25, which is a little higher than 0.2 .

As for the Overscan, of course I'm not using 26 What I'm saying is I can overlap 26 pixel on each side and make them black borders, and they're still not visible on my TV. An Overscan of 2 will give you only 16 black pixel on each side.

So you can use whatever Overscan you like and add this to the end of your script:

Letterbox(0,0,26,26)

I don't like Overscan 4, because the height is reduced too... If you can use Overscan 4 use Overscan 0 and this at the end of your script:

Letterbox(0,0,32,32)

that's it! You save almost 200 mb with this for a 120 min. movie

Alright now everybody who is on the hunt for a good 704x480/576 script, I made some tests, and this script works wonders for me... great compression even at this resolution... if someone likes to try it out: here you go:

Code:
LoadPlugin("E:\MPEG-Tools\FitCD\MPEG2DEC.dll")
LoadPlugin("E:\MPEG-Tools\FitCD\unfilter.dll")
LoadPlugin("E:\MPEG-Tools\FitCD\gripfit_preview.dll")
LoadPlugin("E:\MPEG-Tools\FitCD\dctfilter_YUY2.dll")
LoadPlugin("E:\MPEG-Tools\FitCD\STMedianFilter.dll")
LoadPlugin("E:\MPEG-Tools\FitCD\Fluxsmooth.dll")

Mpeg2Source("E:\Americas Sweethearts\sweetheart.d2v")

GripCrop(704,576, Overscan=0)
Gripsize(resizer="BilinearResize")

FluxSmooth(5,5)
STMedianFilter(10, 40, 0, 0, 10, 40) 
unfilter(40,40) 
TemporalSmoother(1,1)
mergechroma(blur(1.58)) 
mergeluma(blur(0.22)) 
DctFilter(1,1,1,1,1,.5,.5,0) 

GripBorders()
Letterbox(0,0,26,26)

Was it really softer than your earlier script
You encoded at 704x480/576 right? In my comparisons this script still looks sharper than the script at KVCDx3 resolution...
But you're right, it does take longer, so it's everyone's own choice.

Friends You mean res. 704x480 will look better then KVCDx3 544x480? My TV can make letterbox 0,0,32,32 using 544x480

@Jellygoose

Will overscan=0 do anything with your movie if you're using letterbox 0,0,24,24

Overscan=0 won't affect your movie, while Letterbox(0,0,24,24) will blacken out 24 pixel on each side, which will lead to a smaller filesize.

640x272 should look good upsized to 704x480, havent compared it to KVCDx3, but my results with that resolution have all been great.

Hi guys,

I've got a silly question about using overscan/overlap, and figured I'd just ask in this thread rather than starting a totally new one (since this has already been covered some here).

I usually use GripCrop with a 544x480 resolution and 2 blocks of overscan (even on most widescreen movies), because I don't mind the reduction in height that it causes (and I usually need more compression anyways because I need to encode @ 29.97fps for my player). I can't use 3 blocks overscan though because it causes a black border on the side of my TV screen.

I'm converting a longer widescreen movie and I need some more compression, so I'd like to use as much overscan as I can tolerate. What I would like to do is use 3 blocks overscan on the height (top and bottom) of my movie, but only use 2 blocks overscan on the width (the sides).

So do I just have to switch my GripCrop line from GripCrop(width=544, height=480, overscan=2), to GripCrop(width=544, height=480), and then add the line Letterbox(24, 24, 16, 16) at the end of my script right after the GripBorders() line?

Would this give me the equivalent of using 3 blocks of overscan on the top and bottom, while at the same time only using 2 blocks of overscan on the sides? Or am I mistaken? Thanks.

-d&c
