Sorry in advance - CVD ?s

[IndyJones1023]

I read here somewhere, but now can't find it again (and yes I searched). I wish there was a CVD forum. Anyway, someone spelled out bitrates for different formats (VCD, SVCD, CVD, and DVD). I am having trouble creating a CVD stream that any DVD authoring program will accept. If the GOPs are accepted, then the audio is wrong. What I am trying to do is convert DVD-9 VOBs (totaling 7GB) into CVD streams to burn back to a DVD+RW (or +R). The guides here are great, but none really address DVD to DVD+RW/+R coversions using the CVD method. They all seem to spell out how to chop down to multiple CD-Rs. Anyway, I'm not complaining, this is a great community. I'm the guy who made the CVD logo (it's my only way to contribute until I figure out how to do this). So any help is appreciated. TIA!

You could try here : http://forum.vcdhelp.com/userguides/98177.php

The article is about CVD and talks about the resolution, GOP structure, Audio requirements, and more.

Good luck. I haven't had good luck with CVD using DVD2SVCD. WinDVD only playes audio, PowerDVD plays with this one inch green srip at the bottom and other stuff. Maybe I did it wrong. I just loaded the SVCD template then changed to the CVD resolution. Oh, well.

Sorry for the Bad English...
I have also loaded the SVCD Template and switched the Resolution to CVD and i have unchecked the Convert Audio to 44khz Button. Now i have taken Roxio Videopack 5 and loaded the demuxed Streams (Video,Audio) from the CVD. Videopack makes an compatibility Warning because the Resolution (352x576) and then he authored the streams as DVD. I take Nero to burn this on DVD-R and it runs on my Player (Lenco DVD 100/102)

Goto http://www.kvcd.net/

This site has som very good templates for CVD, (for TMPGEnc).

Eeeehhh.... No..
KVCD is another form for xVCD and has no relation with CVD.
The both use the same resolution (frame size), but kvcd is Mpeg 1 while CVD is mpeg 2.

Don't mess up things!

Hi SatStorm.

Because my Pioneer DV-525 don't play CVD's vith MPEG1 correctly,
i use MPEG2 instead. No problem there.

According to my own experience, i can put 90 minuts DVD on to 1 CD-R 80min using the templates from www.kvcd.net, using MPEG2.

Also check this link, http://forum.vcdhelp.com/userguides/98376.php

The result is very good when you convert from DVD.

I think you missed Satstorm's point. There is no such thing as a CVD with mpeg1. CVD does not refer just to the resolution, its a set standard.

Is a MPEG1 KVCD really better quality than MPEG2 SVCD? I thought MPEG2 is very much improvement to MPEG1.

Mpeg2 is an improvement over mpeg1 but much of that improvement is just for practical purposes, ex: support for interlacing, and some even for superficial purposes, ex: OGT graphics, multichannel audio encoding, etc...

The fact is that at the same settings you probably won't notice much quality difference between mpeg1 and mpeg2, assuming your not using a very low bitrate, in which case the encoder really comes into play, (mpeg1 encoders are optimized for lower bitrates, mpeg2 encoders for higher bitrates.)

As far as whether or not an mpeg1 file encoded with the KVCD template is higher quality than a SVCD...well try it out and see for yourself. I certainly don't think it is.

I don't think that the quality of a KVCD is better than SVCD, but the option to put up to 120 min on 1 CD a good quality is interesting. The promblem is, that i make SVCDs with 2 language (german and english) if possible, so in this case there's even less space for the video on 1 CD.

I don't think it is possible to put much more than 60 minutes with 2 audio streams on one CD with good quality.

So in my case i will stick to SVCD. Only CVD is interesting because of the DVD compliant stream, but when DVD burner become affordable noone will talk about SVCDs.

Hi Fireball,
As your choice is SVCD, then you might want to try the SKVCD. As it is, it will give you 60+ minutes on a 80 minute CD-R, with quality equal or above SVCD, even though the resolution is 352x480 like a CVD.
Please download a sample, and see if you like it. You may lower the CQ level, and still find that you'll get very good quality, and at the same time increase your play time close to 90 minutes per CD-R.
Download SAMPLE#1 or SAMPLE#2 here: http://www.kvcd.net/dvd-models
Burn the samples as "Non-standard" SVCD. They should play on every DVD player that supports SVCD.

Enjoy!,

Does tha mean, that TMpegEnc is in any case the better encoder than CCE? But what about encoding speed? I thought TMpegEnc is relativ slow compared to CCE.

On a P4 @1.6Ghz, I'm encoding with the SKVCD a little slower than real-time. About .85 to .9 * real-time.
TMPEG with SKVCD encodes in CQ mode. Try it. Just encode a one minute clip, and see how long it takes to encode that in your machine.
