Here's a teaser of the next generation template.

I'm going to split the templates it two sections.
The current 352x480 and the new XVCD 704x480 ( KVCDPlus )
Take a look and feel free to comment right here in this thread

http://www.kvcd.net/kvcdplus.mpg

27 seconds, 2.35MB

And yes, I was able to fit the complete "Matrix" ( without final credits ) at that resolution

I'm still tweaking and doing some final encodes, but the quality of the sample tells it all!
It's "Near DVD quality" and leaves SVCD like the song "Dust in the wind" . You be the judge

Also, it's more compatible than 352x480, as it's the standard XVCD resolution for MPEG-1 stills.
I should have a final template posted no later than tomorrow.

And this one plays back with Windows Media Player, PowerDVD, WinDVD, etc.

Enjoy,
kwag

I must admit it looks damn good, as good as some of the SBC DivX's that I've seen. One question do macro blocks spoil the image in some of the more intense high motion scenes. Because at the kind of quality that was produced in the sample it might be worth upping the bit rate and splitting the file in two to keep the same quality in those high motion scenes.

kVCD Plus huh... i like the idea KWAG, but is this actually aimed to fit on 1 CD? thats a pretty crazy feat to conquer. getting a little greedy are we? heheh.

i took a gander at the sample clip and liked what i saw, but i see a lot of potential for increasing macroblocks. in regards to compatibiliy issues, this sole purpose makes complete sense.

good luck once again my man. keep amazing us and we'll have to make you a trophy. i pretty FRICKIN big one!

How common is it for a DVD player to accept this xvcd resolution (704x480)? Obviously, I'll just have to try it and find out, but is it common to support this res? My player seems to have no trouble with 352x480, so I'm very excited at the possibility of full xvcd resolution (even if it no longer fits on one cdr... though if it does... muahahhahah).

My dvd player supports 352x480, do you think it will support 704x480? I also have another question. I heard from someone that if I wanted the best quality to just convert with the same resolution as the source file
(ex. 353x272). Is this true, because I tried it and the picture was great but it was pushed up to the very top of my TV screen and the bottom of the tv screen had the last frame of the movie but all scrambled. What was the deal with that? Also, I used the bitrate given to me with the bitrate calculator.


Keep up the good work Kwag.

Here's a sample cut from the full encode of a worse case scenario.

There are some macro, or micro blocks I would say , if you watch closely in your monitor, or pause your player in some parts.

Viewed normally, the high speed action scene and flying stuff just blend with the picture, and unless you're focused at trying to see blocks you won't notice them.

Watched in a TV, there's hardly any visible blocks.

Here it is:
http://www.kvcd.net/kvcdplus2.mpg
About 2.8MB, 15 seconds. Very high action scene.

Enjoy,
kwag

Almost every DVD player that supports VCD's ( and XVCD's ) should play 704x480.

That's because most players support 352x240(28 mpeg video AND 704x480(576) mpeg stills.

So we're putting the "stills" in motion

WOW ....I'm a newbie who discovered VCD over this past Memorial Day weekend. Kwag, I just wanted to say that I am so glad that I came across your site. You are DA MAN! I used cladDVD XP and TMPEGEnc with your template to copy and encode a concert DVD that I borrowed from a friend and it came out to 783MB! And the quality is very acceptable at 352 x 480! Then you put out another template on Monday and when I tried it on the same movie, it came out to 1 GB. I'm not sure if I've done something wrong? Anyway, I can't wait to get this new template that you are working on! Good Luck! and THANKS!

hi kwag,

when I download the sample of your new template my computer crashes (I think the Quicktime thing isnt working for me). Is there anyway you can upload the sample mpeg like the ones on the main page?

thanks

Just "Right click" on the sample link and "Save as".

I right clicked on "save link as" and the download began- I can't wait for your new template because the sample looked superior! It also played great on my dvd player (sony dvp-nc600)

thanks!

Just so everyone tries it, and then we all tweak it for max quality.min size

The first 704x480 BETA template ( KVCDx2 ) is posted in the main page left panel.
http://www.kvcd.net

Only the NTSC is posted, but you guys know what to do for PAL
When we iron it out, both NTSC and PAL will be posted

Have fun, and I want some feedback. Good or bad
Let's have a ball tweaking it

Well I've just watched the high motion scene, and I have to say "Damn I'm impressed." Especially considering the bitrate used. I think I'm going to dig out a couple of my Jet Li films and try the template on some of the high motion scenes in them and do a comparison.
Considering the original limitations of the MPEG format as a whole and the limit of an 80 min CD I think you deserve a heart felt pat on the back.
Kudos man, good work.

Kwag, I'm 40% done encoding "the Matrix" with the new 704x480 temp. and it's looking like the final file size is going to be about 600mb I'm also encoding "Amadeus" and it also looks like the file size will be small (they're both kind of dark (the brightness) movies. Twice the resolution and smaller file sizes is almost too good to be true

So I liked what I seen in that example especailly as if 120mins of that film where made then it would only be about 600mbs!!(i worked that out) And since I have 790mbs to play about with its time to up the bitrate!!!

pros:
fucking brilliant
good quailty
1 cd!

cons:
Lots of picture detail lost (and the fact its mpeg1 dosn't help either)
gt convert to pal res and framerate(may lose bitrate)
That clip was extremely wide(mightend fare so well with fullscreen)

Soloution:
First I am going to convert it to brilaint old pal standards anyhow, next I am going to up bitrate a lot as I will need it for less widescreened movies(theres loads of spare space anyhow so I shouldn't have to worry! 190mbs!) since most films are under 120 mins I might be okay space wise.

If I only uped the bitrate a little to compensate for less widescrened movies and highier res(720x576) and highier framerate(25fps) will I still get 120mins to a cd. A similar pal non-widescreen of this templet may not be possible.

p.s. Any chance for mpg2 as t hate the look of mpeg 1, very dull and lifeless.

Chee Weez rendalunit, me too
I'm at 47% and the file size is 336MB

The sample I posted was encoded with the current parameters, but I hadn't tried the complete movie yet!.

Let's see if our results are the same when we get done. I am using an AviSynth script with TemporalSmoother(1,2). The same AviSynth script I used for the sample.

We know how it's going to look, because that's the same parameters I used to create the sample.

If anyone is reading this, and wants to fit the movie in 2 CD-R's with full blast DVD like quality, go ahead and increase the CQ from 50 to 70.

It will look just like the original DVD
