Hi,

infected by kwag with the news of "whats next on kvcd" i was playin with a lot of programs....

so I have found 2 ways for easy copy ...

1. the traditional way with the templates with the change of the gops 1/3/3/1 and higer the bitrate of choise...and then with the DVD Patcher and with DVD authoring prog to DVD and then the secret with DVd2one123 ( only ) reduce to the sice you want.. maybe remux it and change from 48 to 44 KHZ for sound....

looks great and you can higher the resolution for 1 cd or slower the file..

2. Idea is the way to take the idnetical gop... seen with the prog remux, that there is a differnt gop in the vob file displayed as it is really.....

I take dvd shrink to rip the file without the menu and then i take Instant Copy to reduce the file from 16:9 to 4:3 and lower the bitrate maybe at half of the size ..... last step is take pdiiso and damon tools and dvd2one to ge the desired size....

So we can play with the sound 44,1 or 48 and so on ... the original sound is to big to take it on the cd......

No 1 works on every DVD player I have. Normally i only have the same restriction like before with the resolution... 548/576.... etc..

No2 works fine with the DVD players they havn´t no probs with the resolution......


I hope everyone check this out to come togehter on a higher level for encoding....

Resume :

I find the pic is sharper on details like Nubers on doors or you see that somebody looks on a watch in the movie......

I found out that only dvd2one 123 don´t produce any cluster in the picture... and I think dvd2one liower the bitrate very sucessfull...

Example the encoded picture looks great at 800 MB on one cd after dvd2one operation it looks also grat with 550 MB.....


Check it out.....

greetings from germany

Could you post screenshots or a small sample of a movie that you have "transcoded" in that way?
It still seems very hard for me to grasp all these information, and I think it's hard to believe that you get a good result with this procedure...
Please post a small sample, or at least a screenshot for us!

BtW: Downsampling the sound from 48khz to 44.1khz doesn't affect the size at all... it's just needed for VCD restrictions...

that sounds pretty good!!
I can descibre the prozess a bit better, please and may what tool u need and where get them!!
Can u use TOK for that?? and just change the GOP to 1/3/3/1 // 30??how big one cd to 2 cds??
One small can DVD2one123 reduce files??

Thx.

Although there have not been many replies to this post and not so much of a guide i had to give it a go.

This technique is amazing. It takes relatively no time to convert the .vob files to fit on 2 cds (1 cd the quality isnt that great).

The bit that takes the longest is using headac3he to convert the audio.

If anybody wants to know how i did it post a reply in request and ill let you know.

BTW its really worth trying!!!

g

I really don't wanna try this before I haven't seen a single screenshot or a small sample posted... Can someone who has done this give us something to look at?

Sure Gcar. PM me if you could or post. I don't have much of aclue what is going on here.

Thanks

@gcar

Can u post a some samples,
and than a guide, because I couldnt understand a thing what snowman was talkin about.... and I looks like hes not posting again!!!

It would be awesome if u could do that!!!

Thx man.

Ok, heres how i did it and got superb results.

Original movie (xmen1 around 90 minutes after removing credits)
is just under 5gb in size.

I used Dvd shrink to decrypt and halve the bitrate (50% compression)

I then used Dvd2one to take the halved bitrate vob files and chose a final size of around 1.4gb (decent enough size for any dvd movie). Dvd2one asks you if you want to keep the audio and you do so tick the box.

On my machine (1.5ghz p4) the dvd shrink part takes around half an hour and the dvd2one part around 7-8 minutes.

With these vob files you want to join them up with vobmerge (or vobedit whichever you prefer) then de-multiplex the joined vob in Tmpgenc (the mpeg tools option and simple de-multiplex)

This gives you a .m2v file and a .ac3 file.

Convert the .ac3 file to a .mp2 file using headac3he then rename the .mp2 file to a .mpa file.

Back into Tmpgenc and simple multiplex the .m2v and the .mpa then split this smaller vob file using chopperxp (you can get this from the tools section on www.dvdrhelp.com)

This guide seems to go on forever but must keep going.

Ok. After this you should have 2 .vob files both around 600mb each.

You have the option now to rename the .vob to a .mpg and burn as an svcd or author the vob as a dvd. Guides for authoring dvds can also be found at www.dvdrhelp.com.

Burning svcds should be second nature to you lot so ill stop here.

Ive had success with them as svcds with good quality and im going to try more things tonight when i get home from work. Let me know how you get on and if anybody has any more queries ill try and answer them a little faster than snowman (sorry dude)

Thanks mate will give it a shot.

The only problem I see here, is that you end up with two MPEG-2 CDs at a resolution of 720x480 , and I can't see how this can look good at all on any HDTV or large screen TVs
It's too high resolution for a low bitrate, and specially MPEG-2

-kwag

Great you try it -- that makes me very happy !!

So I have checked some new progs like dvdshrink 2.3 or the brand new CLONEDVD ( elby ).

superb pic quality for 720 X576 with low bitrates....

So I could recomend this way for 2 cd`s the are compatible for the next step into the dvd world.

I hope we find some more new and amazing ways....


For the next step i like to check if it is possible to patch the kvcd matrix in the original vob´s to get smaller files ... so we should check this.

maybe it is possible to get something like Avisync or croped files through this transcoding progs.....

Greetings from crazy Germany

The ideal thing would be, if it was possible, for DVDSHRINK to not only "shrink" the bitrate, but also the resolution
Then you could specify a target of 352x240(28, 352x480(576), etc., and the bitrate would be better distributed. No need for an external encoder

-kwag

Gcar:

Great work........A couple of questions:

1.- DVD shrink version number?
2.- dvd2one version?
I have tried something similar with dvd20ne, but I alwasy receive a message stating that the files received from dvdshrink are codified, and it does not open them (The files are not encrypted)

Kwag:
Have you asked dvdshrink if this is possible to do?

Thanks to both of ou

Totonho03

Not yet. I'm still waiting on some feedback from him, related to KVCD's Q. Matrix

-kwag

Versions then

dvdshrink2 although dvdshrink2.3 is out so best get that

dvd2one version 1.12

Surprisingly the quality of the two cds even though bitrate may be low and resolution far too high is very acceptable. You really just need to try it out to see what it is capable of.

The best thing about it is that you dont have to wait hours on end to see your results as the transcoding process takes no time at all.

I read somewhere that the same techniques that snowman found are the same ones used in digital tv for realtime mpeg2 compression to a small enough size for transmission.

I really hope you get the same results as me and if you are burning to dvd enjoy 3 movies at good quality per disc!!

g

I did.
And although the quality is very good on very low and medium scenes, as soon as there's some activity, you can see macroblocks everywhere
Even the first 50% compression done by DVDShrink starts to produce slight artifacts around objects, and you can clearly see them in static backgrounds. As I said before, 720x480 MPEG-2 on ~1.3GB target is just too high resolution for the bitrate distribution, unless you're doing a real encode and not a transcode. If it was a low action movie, then probably it will be acceptable.

-kwag

I've tried it with "Batman Beyond - The Return of the Joker".

First DVDShrink with level 10 compression (predicted 50% compresion), then DVD2One to shrink from 1600M to 1400M. Joined the VOBS with dvtools, encoded the audio as mp2, remuxed with TMPGEnc, burnt with VCDEAsy.

It's lightning fast. <40min in a P4 2G.

The visual quality is surprisingly good, specially considering it's animation, and ful screen. I'd rank it halfway between a 1 CD encode and a 2 CD encode with "traditional" KVCD. It's definetely worth a try. I've seen some real, commercial DVD's (with Scoobydoo animated episodes for instance)that look worse.

I've looked with Bitrate viewer, average BR ~2000kbps, max close to ~5000kbps.

I'm going to try it with some live action.

Kwag,

I do agree that it does work better with low to medium action film but you have to admit - for the time it takes to do it (much less than full recompression) it may not be a competitor to kvcd but definately an alternative.

Can i also point out that i feel quite proud, ive only posted 4 times on this forum and none of them were requests. I think the only request i may was to get people to try this great technique.

Keep on with the great advancements in video compression

g

Hey great gcar
Yes, the speed is really a time saver, but I would only use it on a low action movie. Yesterday I burned a test on a DVD+RW and watched it on my HDTV, and it really looks good but only on slow action. There was a scene on some leaves on a tree, and when the camera passed close, the leaves looked more like blocks instead of leaves
So I wouldn't use it on a "Lethal Weapon" type of a movie

-kwag

I've tried another movie (101 dalmatians II).

This time the results were not so good.

When there's no "action" it's very good, with very little "Gibbs".

But as soon as the little dogs (each one with all its own spots) start walking - LOADS of blocks, as bad as a VCD real time capture with an ATI AIW
