VV3.0a - PAL Video CD (Sound)

PKowald wrote on 2/28/2002, 3:58 PM

I installed 3.0a last night, hoping to be able to make a video CD (PAL).
It worked however the results are poor.
Picture Quality was OK (for video CD), however the sound was not in sync, also the origional sound track had sharp breaks in it, the result was the Mpeg could not handle it. At every point where the sound was supposed to stop suddenly the video CD glitched (sound on sound off, sound on, sound off....).
Net result is that the PAL video CD is useless.

I hope this can resolved in time.

Hmm, it seems like VV3.0a is worse than VV3.0.
The problem you mentioned is already happening in VV3.0; especially when the video contains JPEG, TGA, still picutres, etc...

Guess, will wait a while before trying out VV3.0a.

Hope to hear more news on VV3.0a

I don' duplicate your experience on this. But I have 2 suggestions anyway:
1) don't mix different picture formats in the same project. VV3 suggestion is using png format and I have used it for long withou problems (create a png copy of your original with Paint Shop Pro).
2) Render an PAL DV AVI, convert to mpeg using TMPGenc and burn.

We are not able to repro your problem. If you render the project to a new track (as a PAL DV avi) and then render that file to as PAL VCD, do you still see the problem?

Thanks for hints to move on with!
I was converting directly from the raw footage and stills I will try again this time from a rendered AVI file.
Note the still I used are JPG files.

OK I tried all of the above with not much better success.
In the clip I use a couple snap to black as the beat in the music stops, a
few times I just snapped to a new image. In every case when the music stops
(it is a sharp stop) bang the Video CD looses it (glitches etc).????
The initial scene is black and snaps to image at the music snaps in the sync
would have to be .25-.5 of a second out!

Do I just give up with Video CD (PAL)

Don't give up. Success is sweeter when it is harder to achieve ... ;-)
1) Uninstall VV3a, re-install VV3. Better stick with the proven version.
2) Convert all your images to png, using Paint Shop Pro.
3) If you are using fade to black or plain black screens, *do not* use empty events (or nothing) as the source of black, create a generated media with uniform color (black).
4) Experiment a little bit of a time. For example if you have a 30min project with the events ABCDEFGHIJ, take all events except 3 from your main project and save under a different name. Then, test only this small sequence (ABC). Then, repeat with 3 more scenes (ABCDEF). Etc. Well, you got the point. Just don't go all along in one time.
5) Something that goes well to me is mute all the *audio* tracks and render all the *video* tracks to a new track (using PAL DV render with the audio tab switched off). This operation takes almost as much time as a full render.
Then, mute all the *video* tracks except the new one, and unmute all the *audio* tracks. Render again to PAL DV, this time with video and audio on. This will be a very quick render. And in synch.
6) As a rule of thumb, I always test*test*test something new before embarking in a full-size project. Better knowing all the problems now that later, when I have 500 hours of work behind me...
Hope this will help.
