120 minutes of SVCD on one disc!

[Greyhair]

I've been doing svcd encoding for over a year. I tried the Kwag template. I'm a believer. I didn't get 120 mins., but then I'm encoding to NTSC. However, I did get 2X my svcd encodes at the same quality. I just want to be sure they'll translate to dvd, which I intend to upgrade too soon.

[kwag]

Kwag,

just to let you know...

i encoded "the matrix" using ur pal template @352 x 288 and got a high quality vcd at 570meg.

thanks for all ur work!

Cool moley!.

What CQ setting did you use?. The Matrix is a pretty dark movie, so you could increase about 4 to the CQ that you had set, and still be below 800MB with higher quality.

hi kwag,

i used ur template as it was.

cq was 70?

any way, i would like to go for a smaller file size without losing too much of the quality...rather than upping the quality/ size

will let you know...

570MB not small enough for a complete movie

Just so everyone knows Kwags template will let you fit up to 140 mins onto a cd.
The quality sucks pretty bad depending how picky you are.
I also ran into problems when encoding as VCD in the res set by teh template, I got white flickering adn so forth. The most noticeable thing you will see are outlines around people that look like the Invisible man, and blocks on darkness and so on.
But It does work
Even with SVCD

[kwag]

As I say:

"Garbage in, ( Real ) Garbage out!"

Specially if you are transcoding from DIVx files to MPEG.

kwag

[mikerios]

I transcoded the Fugtive from DVD, just too see how well it holds up, indeed the template works well if you got a good source, as in my case DVD. It's a pity I do dvd to dvd-r, otherwise if all I had was a dvd rom, I'ld prolly be using Kwag's template and sending him royalty checks, even though my Pioneer 440 will play it and my Sony will not. Good Work Kwag. All and all not bad at all.

... j/k on the royality checks 8)

People,

Just to let you know my findings on this matter.

I converted the movie "The One" from a 699Mb .avi DVDRip. This file was 23fps with DIVXMPG4 V3 video compression.

I loaded Krag's template into TMPGEnc 2.53 Plus and hit start. 7 hours later I was left with a 450Mb mpeg1 VCD file.

My DVD player Sony DAV-S800 plays this perfectly well and the quality is very good. If the quality is crap then I am not interested. Quality is very very important to me.

Anyway I haven't watched the movie fully yet BUT I want to know WHY, when playing with PowerDVD XP, does it tell me the movie is 45min long ? When inserting the disc into my Sony it tells me that the disc is 4568 long.

Have I lost anything apart from the obvious quality differences between the .avi and the .mpg ?

Wanted to say thanks to Krag for that. Now all I want to do now is to convert it to XVCD. :P

[jmjarvis]

Sorry Kwag. Can't even say that R is near the W

[kwag]

Dont worry jmjarvis, I'm getting used to that

BTW, the false times you get , are because the DVD players read the size of the CD-R. So the DVD player thinks that if you stick an 80 minute CD-R, it's impossible to have a longer film!.

So it throws off the time calculations. I've seen this in most DVD players.

kwag

[jmjarvis]

Thats OK then.

Lazy question : Don't suppose you have a KXVCD template do you

[kwag]

Actually that's what it already is!.

kwag

570 meg is small enough, but i want to try and get another film on there aswell, maybe "lotr" or pearl harbour lol
the reason that i want to go smaller is that the avi i made of the matrix was 630 meg, so i would like to see the final mpg at around 450meg..
i will be encoding it tonight, and will post final results later

-moley

[kwag]

@moley


Lord of the rings ( 3 hours ) and Pearl Harbor ( another 3 hours )
You really want to squeeze data onto a CD-R, don't you!

I wonder if one of them will fit at 352x240 and CQ=70 on one CD-R ???

Kwag,

The light levels of a video source can effect the final encoded file size????

BIG TIME!.

For the record, and to add to the list.

I just finished "The Matrix" ( NTSC ) complete with original chapters processed at a CQ of 74 with KVCD template.

Total file size for the movie at 352x480 is 815,040MB for a running time of 136 minutes.

Processed with "Forced FILM" un-checked ( OFF ) in DVD2AVI and used the following script for processing the .d2v with TMPEG.
The script does Real-Time automatic IVTC, filters noise, and correct resize.

The script is automatically generated with the program FitCD. I only added the Telecide and Decimate functions.

------------- start of script -----------------

LoadPlugin("C:\encoding\MPEG2DEC.dll")
LoadPlugin("c:\encoding\decomb.dll")
mpeg2source("F:\THE_MATRIX_16X9LB_N_AMERICA\VIDEO_ TS\matrix.d2v")
Telecide(reverse=false,swap=false,firstlast=false, post=true,threshold=15,dthreshold=9,blend=true,chr oma=false,y0=0,y1=0)
Decimate(cycle=5,mode=0,threshold=0)
BilinearResize(352,352,0,0,720,480)
TemporalSmoother(2,2)
AddBorders(0,64,0,64)

----------- end of script ------------------

Adjustments of input aspect in TMPEG:
Source aspect ratio: "16:9 Display"
Video arrange Method "Full Screen"

Kwag,

Hey, posting specific details of your processing path is REALLY handy, thanks for going to the trouble.

But back to the light levels question. I would expect you to have the same amount of pixel info and 'variance' no matter what absolute level (brightness?) you use. Unless you're talking about darkening the whole picture to the point where mutliple levels of gray 'collapse' into solid black, which I would assume to encode smaller. Is that what you are talking about? And if so, isn't that really TOO dark, if you're losing detail in the blacks?

And yet another question, while I'm here. I've been assuming that when I rip from DVD there would be NO noise to speak of. Does using noise filters on DVD rips also reduce final file size? Why would there be noise?

Thanks for all your feedback!

Thanks Scav!.

The levels of light affect the final size a lot. But I leave chroma levels, etc. as they are in the original film. A good example is "The Mummy Returns, that even with the KVCD template at CQ=70 and 352x240, the final size is around 900MB.

As for the noise, some DVD' are good and some are bad.

If you encode a one minute clip with the script above, and another minute of the same clip without the line "TemporalSmoother(2,2)", you'll see what I mean.
Both in final quality and file size. Remember that DVD's are encoded from FILM and if you look at a movie frame by frame, you'll notice very small spots on some frames ( on some movies ). These are white ( dirt, etc )spots on the negative, and they show as black dots on the final film.
So the temporal filter helps reduce ( blurr ) these noise spots, and give you a higher compression by reducing these noise/sharp spots, etc.

I usually get between 100,000 to 300,000 bytes savings per minute with the temporal filter and parameters as described above.

Kwag,

Well, I will definitely try some noise reduction then. This may be why I never seem to get quite as small a file size as most of you other guys.

Also, was there a specific reason, in the script above, that you chose to IVTC in AVIsynth rather than force film in DVD2AVI?

No reason. Just testing decomb to see if it makes a difference, or blows up!. So far, so good!
