Hi all!

I read somewhere that it is possible to encode at Half-D1 resolution (target is DVD+R) and use it as Anamorphic...
Well I tried it with "The Matrix" today, but I must have screwed up somewhere. The picture is squished horizontally. The stream has a 16:9 flag in it, and when I patched it to 4:3 with DVDPatcher, picture was normal again. however I want an Anamorphic stream to begin with...

Here's the script I used... any help would be appreciated!

Code:
Mpeg2Source("E:\Matrix1\matrix1.d2v",cpu=4) 
Undot()
Deen()
DCTFilter(1,1,1,1,1,1,0.5,0)
BicubicResize(352,424,0,0.6,0,0,720,576)
Addborders(0,76,0,76)
LetterBox(16,16,16,16)

little hint to get more compression Jell:

Mpeg2Source("E:\Matrix1\matrix1.d2v",cpu=4)
Undot()
BicubicResize(352,424,0,0.6,0,0,720,576)
Deen()# or Deen("a3d",3,4,1,4) for light cleaning,great compression but slow
DCTFilter(1,1,1,1,1,1,0.5,0)
Addborders(0,76,0,76)
LetterBox(16,16,16,16)

Jell,

kick the dctfilter() out as you use it BEFORE resizing, thats not the purpose as you already loose high frequencies during downsizing.

thanks people! I'll try the settings out, and I also found out where I screwed up with the resizing!

352 width at anamorph makes NO sense as...

1024/352=2,90 ...means almost 3 times scaled at the width to finally get the 1024x576 (full desqueezed-anamorph at PAL TV!). The result is a very noticable blurried image.

In Regular 1024/704 = 1,45 width scaling factor on TV

ok i see your point inc... then tell me what i can do. i want to backup 388 minutes of video on a DVD+R with acceptable/good quality. that's 6,5 hours. according to the main page KDVD can hold up to 6 hours in Full-D1 (!!) resolution. CQ-Matic gives me an average bitrate of ~1350kb/sec if I use 192kb/sec mp2 sound files... In my eyes that's WAY too less bitrate for 704x576 resolution. even in 352x576 (Anamorphic) the quality simply sucks...

Any ideas?

Hi J3lly
I may be wrong but the "hold up to 6 hours of video" means only video and no sound.
But I may be wrong.
Cheers

You cant say 704x576 up to 6h on one DVD-R in general.
It depends on the movie and its complexibility. So you have to test and ... as I see you already did.
Well 6h also can be done at 352x576 Letterboxed and TV episodes even will look fine at 352x288 ... ask phil as he is doing that a lot.
