Sorry Typo! :oops:
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)

:wink:

Thank you Jellygoose.

I'll give it a try :wink:

Actually,I was a little bit suprised when I thought about overscan 26 :lol:

I can use overscan 4, thatŽs the biggest my tv excepts, dunno how many pixels that is! IŽm just encoding evil dead 2 with that script, 704x576 CQ 72!

Jellygoose 05-04-2003 02:17 PM

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 :!:

CheronAph 05-04-2003 03:23 PM

Thanks for the tip, IŽll try it tomorrow!

Jellygoose 05-05-2003 06:03 AM

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)


CheronAph 05-05-2003 07:10 AM

Thanks, IŽll give it a go!

CheronAph 05-05-2003 09:52 AM

The results weŽre pretty good,

Final CQ: 70,714
Total Time For Predicition: 00:53:17

The image was bit too soft for my taste and it was vary slow, IŽll stick with my earlier script!

Jellygoose 05-05-2003 12:01 PM

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. 8)

Hi guys!

A question: Where are LegalClip() lines :?: :?:

yeah...where? :?
in my samples is used in the begining and in the end of the scripts .

ps:

With some DivX files LegalClip() is coasing avs file reading problems !?! 8)

Friends :) You mean res. 704x480 will look better then KVCDx3 544x480? My TV can make letterbox 0,0,32,32 using 544x480 8)

//Wolfi

PyRoMaNiA 05-06-2003 02:26 PM

It might do, try it out and see what you think. :wink:

Wolfi 05-06-2003 03:00 PM

I forgot, my source resolution is 640x272 :roll:

//Wolfi

Wolfi 05-06-2003 03:21 PM

@Jellygoose :)

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

//Wolfi

CheronAph 05-06-2003 04:36 PM

The results I sended are made with legalclip at the start and the end!

Jellygoose 05-07-2003 09:09 AM

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. :wink:

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

Hi guys,

I've got a silly :oops: 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.
