How do you make a cvd using tmpgenc?

[johns0]

Load the template you want,etc supervideocd and then load the extra folder and choose the unlock template,then go to setting/video and change the size to 352x480/576 and go to gop structure and choose max number of frames 18 for ntsc and 15 for pal if its going to be a dvd.

After seeing this post, I tried making a CVD just to see if my standalones will play them. I did the following:

Ripped a 1½-hour disk w/ DVD Decrypter in IFO mode; Frameserved it w/ DVD2AVI; Loaded Tmpgenc+ w/ SVCD & Unlock templates w/ settings:
352x480 (NTSC), 16x9, 2PVBR (Min 1200, Avg 2150, Max 2520), Audio 44.1k/224.

After doing all that, I ended up w/ one 1.6GB mpeg file. Can I split it for three CD-R's using Tmpgenc+'s mpeg tools (Merge/Cut: MPEG-2 Super VideoCD [VBR])? Also, how do I make BIN/CUE or ISO files for burning? I tested the file in Nero 5.5x, but it's telling me it's not valid VCD file (??).

It wouldn't be a valid VCD. It wouldn't even be a valid SVCD. If you used the SVCD template in TMPGEnc, it encoded it as MPEG2, so you'd need to use the SVCD setting in Nero, if you're burning it on a CDR. Just be sure to uncheck the "create standard compliant" check box when you make the SVCD/CVD, otherwise Nero will try to re-encode the file for you.

My first question is for johns0, ok you told me to choose gop structure then choose max number of frames and change it to 18 for NTSC if iam maken a dvd well iam not making a dvd iam making an svcd/cvd so would I do anything with the gop structure or just leave it at zero?


Anyways next question, with tmpgenc if you use the svcd template and then change the resolution from 480x480 to 352x480 then basically that know makes it an cvd, well if your using the svcd template shouldn't it still play on most all dvd players regardless of the change in resolution to make it a cvd? it would still be an svcd because thats the template you chose right?

No. It is called SVCD because it is 480 x 576/480 with max bitrate about 2520kb/s with 224kb Audio at 44100khz.

Many NTSC DVD Standalone players are not compatible with CVD.

[j1d10t]

SatStorm is correct -Even if your player will play SVCDs, it might not play CVDs. If you authored the CVD file as a DVD, on a DVD, then yes, your player would play it, as CVD is (basically) a DVD standard - CVD is (basically) a 1/2 D1 DVD, except the audio would need to be at 48k.

As for the number of GOPs, you may want to set it to 18, but it's up to you. I've found that I get (slightly) better results with it set at 18, but I've also made a bunch of CVDs with it set at 0 (when I was first experimenting with CVD). So I really wouldn't worry about the number of GOPs.

[SatStorm]

In the matter of fact, there are not GOP limitations for SVCD and CVD. The GOP limitations are a DVD thing.
I use to suggest when the hype about CVD first appeared, to keep the max GOP 15 for PAL and 18 for NTSC for easier future transfers to DVD - R discs (no re-encoding needed for the video part, only the audio needs adjustment that way).

CVD is an official standard of China and all the SVCD compatible players in China have to be CVD compatible.
It is not 1/2 D1 DVD at CD-R. That is miniDVD.

I was re-reading your article that you wrote a few years ago, and it said that only 40% of R1 standalone players played CVD, and that was because they were made in SE Asia using C-Cube's mircoships.

I have two DVD palyers: one made in China and the other made in Malaysia, and they both play my CVDs. In my case, your theory seems true. So if I were to buy another DVD player that will play CVDs, does that mean DVD players made in SE Asia will have a good chance of playing CVDs?

That's why I said "basically" But for what this person want's to do, I figured it was best to not overload him with info at this point That will come later when they start experimenting, and things don't work - then they'll start reading everything they can get their hands on about the subject

I did not know that there were no limits for GOPs in SVCD - you learn something new every day It must have just been my eyes that made me think I was seeing a difference

[SatStorm]

The GOP lengh (stracture) actually does a difference. Kwag and his possie are extremely testing those stuff years now (www.kvcd.net).
But the GOP size is a limitation of the DVD video format. With VCD/CVD/SVCD, there are no limitations about this.

IMO, you can see a picture quality difference only on low bitrates with some GOP stractures and only if you see close. But others see a difference to the slighty change...
With higher / fair bitrates (example: 3200 for 1/2D1) you don't see a difference IMHO for real.
