Why did you use a static script and not the optimal MA one ?

Note1 : you're player support MPEG1 at 23.96 fps ? That is not a standard framerate. Be careful ! I thought my player supported it also until the day I encoded a subtitled movie : the subtitles were flickering so much that it was impossible to watch ! For sure, all the image was flickering like the subtitles but I never noticed it.
Since this day, when I have a 23.96 source, I used MPEG2 and "3:2 pulldown during playback".

Note2: a VCD resolutoin with overscan=2 ? Thats is big ! Don't you see the border on you TV with such values ?

Phil,
the first reason is "for test" the quality,i really like this deen parameters posted!
the second is that i don't like the "blur" in the moviment scenes from MA!

:!:

ps:
i did tests with lanczos without asharp too!
is seamless(quality and size) with bicubic and asharp but
i see better contrast with bicubic and asharp(my taste)!
using only lanczos is faster!
:wink:

hey Phil,you edited the post with more question!
:lol:

note1:
yes,my 2 players can do it,and was without subs.

note2:
8O
i don't see in the tv .....i'm burning a cdrw for test!

thanks for advice!
:wink:

Zyphon,
good questions!
:wink:

So let me tell you that I drop Deen recently because it removes to much details (even if I didn't try the last parameters posted).

I'm currently testing this :
Code:

Convolution3D(1, 6, 12, 6, 8, 2.8, 0)
Tonight I'm doing my second movie with this, so I can be positive about its quality. But if you want to try.

My complete script is :
Code:

BlindPP(cpu=4)
Convolution3D(1, 6, 12, 6, 8, 2.8, 0)
LanczosResize(...)
Undot()
TemporalSoften(2,7,7,3,2)
DCTFilter(1,1,1,1,1,1,0.5,0)
AddBorders(...)

ME TOO !
I tried the MA script a lot but I never burnt any of the movie I did ith it. Just quick watch for testing purpose ! But I use it for other people asking le to do backup of their DVD. Don't ask me why :-)

You can raise the treshold (trigger point) in the MA script, to start the blurr at a higher value. This way, only on very fast scenes blurring will be applied.

Change the line in the MA script from:
SwitchThreshold = (Width<=352) ? 3 : (Width<=480) ? 2 : 1
To:
SwitchThreshold = (Width<=352) ? 12 : (Width<=480) ? 6 : 3

:D

thanks for this and for the news in the MA script that you did today!

@Dialhot & jorel

Do you still use 2000 for max. bitrate or do you raise it to 2500 with your static scripts :?:
And what about the min. bitrate? Do you always use 300 for that and not the "Average X 0.57" from CalcuMatic?

@ audioslave
in this case(352x240)mpeg1 i use min300 and max2000.
for mpeg2(352x480 or more) i use min300 and max2500.
i never use "Average X 0.57" in all situations, 8O
i use the average bitrate and time from CalcuMatic and use in CQMatic
to get the CQ and......encode!
see that i got 802mb (822.004kb) ---> 1 cdr 700mb (80 minutes)
using one source with 152 minutes without problems!

@ Phil
you was (is) right :!:
with overscan 2 give big black borders in tv with 352x240!
i re encode with overscan 1 and got CQ18,99 and final size
:arrow: 801mb (820.283kb)with audio 128-48k! (movie 152minutes)
using CalcuMatic and CQMatic like posted !

script used ("cocktail" to got more CQ)
mpeg2source("D:\DVD\HP.D2V")
Convolution3D(1,6,12,6,8,2.8,0)
Undot()
LanczosResize(336,224,0,0,720,480)
Deen("a3d",3,6,1,6)
DCTFilter(1,1,1,1,1,1,0.5,0)
AddBorders(8,8,8,8)

a big mistake in the name of the movie:
is harry potter - philoso~... stone and not secret chamber!
:oops:

Dialhot 10-25-2003 08:00 PM

For my part : never used the 0.57 value also, min = 64 everytime, max to 2300 for usual "not so long" movie (1h40), 2000 for movie near 2 hours.

With such values and my last static script, CQMAtic gave me 3 movie of 796, 802 and 806 MBytes (note that I don't use the CD80 setting but a manual setting of 807Mb in calcumatic). So all that is perfect !
