SKVCD - A step beyond CVD and SVCD.

[Bobby]

Kwag any chance you can post your fit cd settings? norammly this would all be done in dvd2svcd for me I used fit but its a tad bit complictaed and doesnt end up like your sample does after encoding

[Mxjshaf69]

Wow Nice work!!! I tested it and liked it. Here are my results
SKVCD File size 50.4 MB CQ 80
SVCD File size 63.1 MB CBR 2520
SVCD File size 50.4 MB CBR 2060
No Difference in quality to my eyes between SVCD standard and SKVCD standard, and i'm a quality freak. DVD with CBR 6000 barely looks better than it. In order to get the file size of SKVCD on svcd you have to drop the bitrate down to 2060. The only bad is in CQ there is no control over file size so if it is just a little too big for two cds you have to use a third with hardly nothing on it.

Just encode the video stream only. Then, depending on the file size, encode your audio acordingly
You should be able to fit just about any 120+- minute movie in two CD's.
( Wide screen, and encoded at 23.976fps ( or 25fps for PAL )

Hey kwag could you post a reply to my previous post about your fit cd settings plz?
Thanx Bobby.

Here's a FitCD script you can use as reference:

LoadPlugin("C:\encoding\MPEG2DEC.dll")
mpeg2source("K:\KATE_AND_LEOPOLD\VIDEO_TS\kate.d2v ")
BilinearResize(352,352,0,0,720,480)
#TemporalSmoother(2,2)
AddBorders(0,64,0,64)

The audio is processed separately. I open the VOB's with MPEG Mediator and export the AC3 audio as a WAV file. Mediator downmixes the surround information, so the WAV file has the dolby information. Then I encode this WAV file with headac3he, and multiplex the video/audio streams with BBMpeg. Result is perfect sync every time 8)

Thanks kwag!!
But is their any chance you could post a avs script you would use for a PAL movie? (352 x 576 instead of 352 x 480?) I tried altering the avs script but I must be altering the wrong values as in tmpgenc it detects the source as 352 x 480 all the time (as i said i never wright the avs scripts as dvd2svcd does it automatically ). Also what settings do you use in tmpgenc?
Ie what source aspect do you use and what do you set the ouput aspect ratio for svcd as? (4:3 or 16:9) just curious cause i wanna get the exact settings you used for the sample.
Sorry about all this hassle Kwag
Thanx a mill.
Bobby.

Sorry about a PAL sample. I don't have any PAL sources.
About the input aspect, I encode with the KVCD templates as they are set, Full Screen. The proper aspect is already fed to TMPEG by the .avs script. So you don't have to worry about it.

@kwagster

Yea well. The only reason for cvd is for the standardness so it will go on dvd. Since yours aint dvd compliant (we talked about this before) it aint good for that. And since it has to go on 2 cds (at least) the 2 cd 720x576 templet well over does it. Even though in theorey the bitrates used should look bettter at 352x576 then at 720x576 its kind of like comparing a 9mbs dvd to a 9mbs cvd. which is better?

If you want a SKVCD on a DVD, the only changes required to be DVD compliant are:
Audio -> 48Khz.
GOP -> MAX frames to 15 ( PAL ) or 18 ( NTSC )

That's all! And you STILL will get smaller file size and better quality than a standard CVD, because of KVCD's Q. Matrix.

Hi Kwag,

What is the type of source file you are using to feed into TMPGEnc for this template? Is it DivX, or a d2v file?

For some reason, I have found that with standard VCDs (so MPEG-1), a DivX made from .VOB files makes better quality by far than a d2v file, which is frameserving, if I'm not mistaken. Why is this?

Thanks!

Mostly VOB's, frameserved by MPEG Mediator, or a .d2v processed via an .avs script. But it can be anything. TMPEG is what's going to see the material anyway, so it's not template related.

Hi there kwag, I was wondering if you could help me test out your new template????

I have lots of anime I just downloaded and I burnt them out to SVCD, and I can only fit an episode for every cd (each episode is only 22min).

Now, I have a wide screen t.v. at home, (57"), does your template allow for my 640X368 divx video to be encoded so that it isn't stretched when it's on my t.v.?

also, is your template NTSC? or is it pal? if it's not NTSC, can you tell me how to make it so?

thanks a bunch!

[Trifu]

also, this is gonna make me sound like a total newbie........
but when I click on your template link it didn't download a tmpg template file,
how would I make what you posted on that link into a tmpg template file?

Whats the time like kwag. I mean if the speed is better than CCE then this templets a winner. Also will it get 60mins per disk when the gop is changed?

If you don't change the GOP, and don't care about DVD compatibility ( most people don't ), the template will create 60+ minutes on a 80 minute CD-R with the quality of the samples I provided. The 60+ minutes is, of course, encoded at 23.976 ( most movies are anyway ) and "Wide Screen".
If it's a "Full Screen" movie, the time will be around +-50 minutes on a CD. I haven't done any benchmarks on encoding time. I did the complete "Kate & Leopold", but I didn't look at the time it took to encode. It should take about the same as using the standard TMPEG SVCD templates, but encoded as CQ mode, which is what the SKVCD templates are set, for encoding.
