CVD VS. DVD ?????

[SatStorm]

The SVCD framesize ain't compatible with DVD-Video, yes.
From what we know untill now at least!

Again, thank you for the information, great job!

Wow
Am I a confused man now

Ok my DVD player plays CVD or XSVCD or what ever you choose to call it.
I've been led to believe that 1/2 DVD Pal is 352 x 576 Mpeg2 48hz.
I've been making CVD/XSVCD at 2520 bitrate with these settings.
They play fine in my DVD player.

Am I correct in thinking when I get a DVD writer I will be able to extract the video from these CDRs. Then without re-encoding burn them straight to DVDR and they will be 100% DVD compliant?

Cheers

So basically after that little flurry of posts the answer to my question was YES

Yes, if you follow a GOP structure compatible with the limitations of DVD-Video.
It is all explained on the CVD faq you can find in this site.

Hey everyone. I was hoping that someone would bring up the CVD to DVD thing in this post. I have been (using Satstorm's guide and some others) making CVD's for awhile now (140'ish to date) in anticipation of burning them onto DVD-R media once I got a dvd burner. Well, over the past weekend, I finally bought a burner (the cendyne 4x dvd-rw burner) and am planning on doing a burning marathon this weekend.

The two things that I am confused over is the GOP structure thing and the audio part.

For the audio part, I have been, using dvd2svcd, been doing the audio at 192 instead of 224 (however, at 48mhz). Is that going to cause a problem with true dvd compliance. I have an apex which will play a chocolate chip cookie if need be, but I want to to make my dvd-r's compliant for any dvd-r compatible dvd player. Will there be a problem with authoring the dvd-r by pulling in the 192 audio or should I just resample it up to 224 just to play it safe.

For the GOP piece, I understand what it is and what it means from a textbook standpoint, but just dont get the relevance over to the DVD world. I used baker's guide for doing cvd's for dvd compliance and I never closed the GOP's. The spec from my readings is 18 for NTSC (15 for PAL), I don't understand how I can determine if my CVD's are in spec for this. I am going to seach some other forums and see, but figured I'd throw it in here and see what y'all thought. I am guessing this will be on the minds of everyone that has been making CVD's in anticipation of the DVD writer.

Here Here! The SVCD/CVD faq right here on this site gives a good history of CVD, and it's successor SVCD.

Fozzee, your CVD would be DVD compliant, if you resample the audio to 48Khz (48,000 Hz). The CVD spec calls for 44.1 Khz. DVD spec for this resolution calls for 48Khz. DVD supports both MPEG-1, and MPEG 2 (MPEG-1 is allowed only in 352x240 or 352x288 res).

Last but not least, VBR is only supported in the MPEG-2 streams.

Full specs and notes here:

This was good reading. Very verbose, so don't bother if your not interested. According to this, CVD was considered THE standard. I hadn't heard this slant before:

In 1998, a format called Chao Ji Video CD (initially called CVD) became an industry standard in China, solidifying a number of mutually incompatible specifications-CVD, S-VCD, HQ-VCD-that all popped up during the same year.

One other piece, that I believe was a hot topic:

Today, Chao Ji Video CD is no longer a disk-based standard but instead describes a multistandard player that accommodates the original CVD spec along with S-VCD, Video CD 2.0, Video CD 1.0 and CD-Audio.

Off topic, I came across this, which I was also very interested in, regarding the next generation proposed specs for High Definition DVD:

Hi
My CVDs are already 48hz .I know that 44.1 is the standard for CVD.
And they play fine in my DVD player.

One more good link..this contains the specs for Blu-Laser. 36GB per single sided disk, and a proposed 50GB dual layer version. I hope they go with MPEG-4 rather than MPEG-2. MPEG-2 is getting a little long in the tooth.
