[u]Notice to all svcd users!! Make your svcds dvd compatible

[Bizarro]

Well I found this @ another forum I thought everybody here could use
this in future CVD rips :::

Question :::What is the specification in terms of resolution for Half D1 PAL and NTSC?

Answer :::
Here are the settings that should be accepted w/o conversion:

Audio
WAVE Audio for Windows 48 kHz, 8-, 16-, or 20-bit stereo (.wav)
MPEG-1 Layer 2 Audio 44.1/48 kHz, 8-, 16-, or 20-bit stereo (.mpa, .abs)
Dolby Digital 48 kHz, 8-, 16-, or 20-bit stereo Bit-rate: 96 to 448 kbps (.ac3)

PARAMETER NTSC (525 lines @ 60 Hz) PAL (625 lines @ 50 Hz)

Recommended source picture resolution:
NTSC 720 x 480,704 x 480, 352 x 480, 352 x 240
PAL 720 x 576, 704 x 576, 352 x 576, 352 x 288

Frame rate:
NTSC 29.97 Hz
PAL 25 Hz
I guess I'll try the 44Mhz audio and see if this is accurate, I hope so ,it would save ALOT of converting

now i notice u say on another post that::::

pal= 720x576 or 352x576
nstc= 720x480 or 352x480

so that mean most of us in the u.s.a gotta use nstc correct ????? wo we use 480 and not 576

[Bizarro]

you are correct U.S. would be :

352x240 is U.S spec 4 VCD/DVD
352(480)x480 Is U.S. spec 4 Svcd/DVD

............................................Bizarr o

Unless your DVD Player is able to play all regions .My Apex plays all regions so I can either incode in NSTC or PAL and my player will play it

[baker]

res= 352x480(576)

sound= any dvd/svcd compatible sound you wish

i really havent used nero for about a year and a half...... for my vcd's i use adaptec with no problem.... but i made my first cvd and i want to know how to burn a cvd using the newest ver 5.5.8.2

[Alcohol]

forget this post my question had already been answerd..

[mol3000]

i still need to know what i select for system....... do i select standard svcd or just keep svcd program slected...... i did my first cvd on with the 478 res and its having a little problem playing.... i am gonna burn one tonite using the 500 something res and see if anthing change

[mol3000]

ok... i burnt a cvd at both 352x480 and 352x576 and i still am having some problems..... i have the new bose 3.2.1 system.... it plays cd-r/rw just find....... when i put it in it comes up and says loading on my bose system but the sounds comes right up and plays with no picture........ but here is the strange part...... when i hit menu to look at the settings on the 3.2.1 surround system , what comes up behind the menu but the cvd picture....... and thats at both resoultions...... so basically i have to sit there with half the menu blocking the movie just to see it........... can anyone help with that????!?!?!?!?!?!? also is there a offical cvd template for tmpgenc ?????????

[Sefy]

I agree with energy80s on converting the Audio to 48khz, whatever program you want to use to do the actuall encoding of the Audio, i've not had a single problem with a VCD in 48khz quality instead of 44.1khz, i've even set the latest Templates to be at 48khz for "future" compatibility

[Mntneer]

I've been doing this for a while now, and can't understand why other people don't.

If your DVD player handles SVCD's, then more than likely it will handle Half D1 SVCD's. All the Apex's I've used can.

Also, it's a MUST to do audio at 48KHz. Otherwise you'll have to re-encode to move to DVD.

And you're correct. Picture will look better at Half D1, than at 480x480.

If you have, or plan on geting, a DVD-R drive, then this is a MUST!

i was wondering if anyone could help me with my question above.... i think what else would be helpful is to know what the dvd looks for to play the movie..... maybe if i make a couple of changes to the cvd then it wll play correctly

I havn't tryd the newest version of Nero , I like the version that came /w my burner. The version I have you would select 'Svcd' and uncheck the 'create standard compliant CD' . then just drag-n-drop your CVD MPG file over . Then Burn

As for your DVD Player it will see your CVD as a Svcd until you convert your CVD onto a DVD-r , if done correctly your DVD-r will be read as a DVD...................

Whats the difference between CVD and X(S)VCD, which as I understand it are just non standard (S)VCD's.

Craig

[energy80s]

A CVD (China Video Disc) is an xSVCD. It uses MPEG2 coding and half the frame height of normal TV/DVD. Therefore it is sometimes called half D1 resolution. As it is only coding half the picture of full D1 the picture quality is subjectively better for any given bitrate. Also as it's an officially recognised frame size (D2) its compatible with most players - even Media Player plays it correctly!!

[DVWannaB]

THIS IS EXCITING STUFF!!!!!!!!!! I AM SO EXCITED I AM TYPING IN CAPS. I AM GOING TO TRY IT OUT TONIGHT WITH AN AVI MOVIE I RECENTLY CAPTURED @ 480X480. THANKS GANG!!!!!!!!!!!

[bbb]

There still a bunch of variables that need to be clarified for CVD/VCD to DVD compatibility.

1. Is 23.97 fps permitted in DVDR specs? If so, should one use 3:2 pulldown or just progressive encoding?

2. How about 44 khz for sound? I know 48 khz is the spec but does 44 khz work just as well?

3. How about GOP settings (Output sequence of interval header, Max number of frames in a GOP, Closed GOP vs Open GOP)? Does the standard SVCD/VCD GOP settings work?

Please answer with reliable theoretical knowledge or better yet, with real world experience in making these conversions.

[scissors]

all i need to know that if i stick it in a dvd player will it just up and play.... u did say that cvd is automatically dvd compatible......also this is the only mpeg 2 codec i saw

"MPEG2...... Codec Play MPEG2 directly with Windows Media Encoder and you can also open MPEG2 directly in most encoders such as TMPGEnc. Warning! This codec may cause sync problems when playing MPEG2s if so use instead WinDVD or PowerDVD. Freeware"

i was wondering if there is another one out there.... especially that doesnt cause sync problems with the audio (hates when that happen)

hello baker, and good morning.

I've been interseted in this standard for a while. If it's on DVD it's d1, yes? but if it's on cdr it's chinese spec?

Gops, what a large gop, i use 12,3. Is that classed as large? I thought it didn't matter as long as B divided into P?

[kwag]

Just a little note for everyone thinking that they can just re-encode the audio on SVCD and burn the video as it is to DVD.
The GOP for DVD is very strict. The GOP structure can't be longer than 15 ( or 18, don't remember exactly now ).

So just about every SVCD will have to be re-encoded for DVD compatibility.

No DVD authoring will read an SVCD mpeg video as compliant.
Even if the audio is 48Khz.

Not to mention that 480x480 is non-standard for DVD. 352x480 1/2 D1 is.

( Just another reason to keep using KVCD's )

Couldn't one use Close GOP in Tmpgenc for dvd compatibility? Someone with a dvd burner please try this out.

[scissors]

okay. I did a quick test this morning.

I basically took the template/set up i have been using for 120min svcd altered the width to 352 and the sound to 48KHz. Obviously this meant because of the reduced width the quality setting in tmpeg can be knocked up a couple of notches.

I made a svcd bin with vcdimager classic (which obviously reported non compliance). I added an empted SEGMENT folder to the bin using winiso and burned.

The result worked fine in my alba dvd103, which actually report the res as 1/2 d1 mode.

I'll now check on friends and family's players.

OKAY. So here's a question. Can I assume if i can get a whole film on one 80 CDR, does that mean I can get 3-4 on a DVDR?

I think i'm safe in saying most SVCD being done is either TMPEgs default,
1,6,6 - 1,4,4 - 12,3, 15,3 or there abouts. All fall into the size of GOP spec.
Anything bigger than 15 does nothing to improve compression or quality and causes delays when ff.

Doesn't your template use MPEG 1 VBR?

I don't want to get into one of those protracted arguements, but that's about as incompatible as you can get.

Now, this SVCD done as Mpeg2 D1 Res and 48KHz then remuxed with BBMpeg DVD settings is COMPATIBLE and looks great. If you get a DVD Writer all you gotta do is get ISOBuster and extract the Track and author.

Thanks Baker. I know which direction I'm now looking

KWAG mate, your template is REDUNDANT.

[thxkid]

Try this on for size guys, I have the newer Daewoo 5800, so I burn alot of my non compliant SVCD's at 704x480 from 3200 to 6000 bitrate use the 99min. CD-R's, play fantastic in the daewoo and should be no problem to convert over to DVD's if and when I want to, at 15cents each at 3 discs for 45 cents sure alot cheaper than a DVD-R and looks just as good, specially the 6000 bitrates, parents just got a Daewoo I did a movie off on 3 discs at 704x480 at 3400 bitrate and they just loved it, even on their 50in big screen.

Here's a little more info so that you can see how fun it can be to turn an mpeg file DVD compliant.

"The DVD specification requires that a Sequence header be included immediately before each GOP (Groups Of Pictures) in the MPEG-2 stream. Some Authoring software will analyze the MPEG-2 file being imported and report an Error if this is not present. With others the file may be allowed to be imported but the final DVD will not play in a Set Top DVD player. When setting up to encode the DV file to MPEG-2 IBP (VBR) look for a option such as Sequence Header... and select to include a Sequence Header at at all GOP's. Some encoders may do this automatically when you select the option that you are encoding to create a DVD. Just about everyone does it differently and has different options, so you may have to experiment or contact the software creators if you hare having problems. This is imperative for files to be imported into Sonic ReelDVD otherwise ReelDVD will not accept the file and will display an appropriate error message.
The fields per GOP are defined by the specifications:
PAL 30 fields/15 frames
NTSC 36 fields/18 frames"

After comparing Tmpgenc's DVD template's GOP pattern with that of the SVCD GOP pattern, I found them to be identical.

Arguably, this comparison doesn't guarantee absolute DVD compatibility, but I will trust these settings for now.

So my CVD encoding settings are as follows:
352x480, 2-pass VBR (900-1800-2450), 23.97fps, 48KHz

Encode with: VBV:0 (auto), 3:2 pulldown when playback, field order: top field first (field A).

Wish me luck for future DVD compatibility (hopefully, the real world standard--when a dominant DVD writable format is chosen--will be flexible to master our CDR encodings).

[bbb]

scissors,

Can you confirm if a 23.97fps encoding using your template plays perfectly on your standalone dvd player?

Which brand of player are you using?

Mpeg sequence maker can insert sequence headers at an interval of 1 per sec or so, ensuring that you have one preceeding every GOP. It doesnt take long at all either.

"A CVD (China Video Disc) is an xSVCD"

A CVD is really not an xSVCD, it is a standard unto itself. Saying a CVD is an xSVCD simply because it doesnt conform to the SVCD standard is like saying a DVD is an xSVCD for the same reason.

The CVD standard was incorporated/made obsolete by the SVCD format. The Super VCD standard, commonly referred to as SVCD, actually incorporates three formats; SVCD, HQ-SVCD, and CVD. It was decided that the final Super VCD specs would use 480x480/576 resolution, however for political reasons all SVCD compatible dvd players were required to also play CVD's. So while CVD's do not comply with the SVCD standard, they are still %100 compatible on all svcd compatible dvd players. Heres some more info if anyone cares to read the full history of CVD and SVCD...
