[b]Help with CVD authoring[/b]

[tpham]

Hi all,

I've just in the last couple of days come across CVD and have also found some settings that claim to produce excellent quality CVD. My understanding is that CVDs are just SVCDs but are resized differently CVD (352 x 480/576) instead of SVCD (480 x 480/576) and therefore produce better quality video than SVCD. (You may say why not try XSVCD instead of CVD since XSVCD is better. I've tried to produce XSVCD but my dvd player doesn't seem to function too well with this format. The video quality if quite good however, the audio is shocking. Hence, I am looking into CVD.) Back to my orignal problem, I've been using D2S for some time now to produce SVCD, so last night I decided to try my luck and encode a CVD. The end result works perfect on the computer, however, in my dvd player it fail to play. It just loads the video and just hangs (no sound at all and the video is blocky). I have (3) questions;

1. Is my understanding of CVD correct that it is just SVCD but resized differently (352 x 480/576)?
2. Can I use D2S to product CVD encoded as SVCD, mount it as SVCD using Demon and burn the image as SVCD using Nero?
3. If my dvd player can play SVCD should it then play CVD encoded as SVCD or do I need a player that supports CVD?

Please help I am very confused....

Buy another DVD player or stick to standards , have you tried KVCD templates?

[macleod]

1. yes
2. yes
3. ???? might help if you mentioned what dvd player you had and/or if you confirmed that it plays CVD by matching it against the dvd player compatibility list on the left.

Thanks to everyone that responded...

I managed to get my dvd player to play CVD...works just fine...

One question though...I know that CVD is 1/2 DVD, since this is the case are we meant to only see 1/2 the screen. I don't know how to word it exactly...what I am trying to say is 1/2 the screen contains the movie while the other half contains the black border as follows (1/4 black border, 1/2 movie, 1/4 black border) - I hope this makes some sense. If this is correct than isn't this a funny way of watching a movie?

[macleod]

No, this isnt correct. With CVD, which would actually happen is that the "missing" 253 lines are "stretched". It should look NO different than if you were to watch a normal DVD on your TV.

Sounds like you have a 16:9 or letterboxed movie. If the source did NOT have this, you may have encoded it wrong.

What was the source? (not movie, but resolution and whatnot).

Thanks again macleod for your prompt response...I can't really tell you because I'd never taken any notice...I mostly encode 4:3 letterboxed and have recently only encoded karaoke dvd. These karaoke dvd do not specify anything about resolution etc. so I never looked into it. My encodes are all working correctly in SVCD format. Its just that I've been trying to achieve better video quality that I looked into CVD. I will try to encode a chapter of a movie where I know what the resolution is and see how it goes...

CVD questions......

1. CVDs are altered SVCDs, right?
2. are they burned on CD-R media?
3. if they are burned on CD-R media, does the CVD audio stay at 44.1?


thanks.
