CVD

Does any one know where to get a template of a CVD for TMPGEnc??
Do u burn a CVD as a SVCD using Nero?

[adam]

The only real difference between a CVD and a SVCD is the resolution, so just make a template yourself.

In TMPGenc load the SVCD template, either ntsc, ntscfilm, or pal depending on your needs. Then load the unlock template. Now change the resolution from 480x480/576 to 352x480/576 and click save and name it CVD. Now you have a CVD template.

Yes just burn it as a SVCD in any SVCD authoring/burning software. Ignore any errors or complaints about it not being compliant.

oh right, thanks. One more question how many minutes will i be able to fit on a 700mb CD-R with CVD & will the encoding take longer?

[adam]

Just like SVCD, CVD supports VBR encoding up to 2.6mbits for video and up to 2778mbits for total bitrate (audio + video + subs + additional multiplexing overhead.) So the playtime you get per disk depends entirely on what bitrate you choose to use. Generally speaking though, most people aim for between 40 and 50 mins per disk in SVCD. Since CVD uses a lower resolution you do not get as many artifacts at the same bitrate as SVCD, so you may be able to fit up to 65 mins per disk in acceptable quality, though I think you should try to always keep it under 60 mins per disk if possible.

Compared to SVCD the encoding time should be less with CVD since you have less pixels to encode, but the difference will probably be marginal.

Any form of mpeg2 encoding will take longer than mpeg1 encoding and it will be even longer if you use VBR, and certainly longer if you encode using multipass VBR.

You missed one thing adam. You also have to change the audio from 44.1 to 48.

[adam]

No I didn't PlaiBoi, CVD does not use 48kHz audio it uses 44100kHz. Like I said, other than the resolution and some very minor differences hardly even worth mentioning ex: filenames, the CVD and SVCD standards are EXACTLY the same.

no you don't. CVD standard is 44.1Hkz. I you want a SXVCD or
you want a dvd half res mpeg-2, you can use 44.8Hkz + some
gop changes.

My apalogies Adam. I had misread the article on CVD and was under the impression that it used 48 khz audio.

[Lost_Soul]

what happens if u encode it with 48Khz audio? coz thats wot i did

[adam]

Well it just isn't complying to any standard anymore so you may have problems playing it on certain dvd players.

[PlaiBoi]

People encode it with 48khz audio so that it will be DVD compliant. So that if in the future you get a dvd+/-rw drive you can turn those multi-cd CVD's into a one DVD.

Most standalone DVD players that support SVCD will also play audio sampled at 48Khz on a SVCD. Just burn a small test, and see if it plays in your DVD player.

Yup 48khz audio works perfect and wicked quality . thanks
