possible to encode Half-D1 resolution as Anamorphic?
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... :roll: Here's the script I used... any help would be appreciated! Code:
Mpeg2Source("E:\Matrix1\matrix1.d2v",cpu=4) |
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. |

i had problems with DCTfilter in the past(was posted in scripts forum) and was forgot!...good memory ink! |
thanks people! I'll try the settings out, and I also found out where I screwed up with the resizing! :wink:

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. |
