Where's that "How to create a DVD compliant CVD" g

[fmctm1sw]

The topic is supposed to say "guide" too

cvd is just an svcd with a different resolution (352X576)
no need for a guide.

there is no such thing as a dvd compliant cvd.

what you CAN do is a dvd with 1/2 D1 resolution
which is a dvd with 352x576 resolution.
it is different from cvd because the audio is 48000 and it is multiplaxed as a dvd.

just use the dvd template ,change the resolution to 352x576 and make the bitrate whatever you like.

this will create a dvd compliant file with a resolution of 352x576.
if you want to burn it do a cdr as an svcd, you might have problems with the audio (its 48000) or with the video (its 352X576).

just try it in your player and see how it goes.

and if you do it that way you might want to multiplex it as "mpeg2 super video cd vbr"

I believe there was something that needed done with the GOP structure.

If your using tmpgenc for encoding set gop to max of 18 frames.352x480 or 352x576,depends on your source file.

The easiest way to make a CVD that will work on a CD now but will also work on a DVD disc later is to use TMPGEnc

Use the WIZARD MODE and select the DVD template. Simply set your resolution to Half D1 (352x480 NTSC or 352x576 PAL) and limit your bitrate of the video to no more than 2500kbps and use 224kbps MP2 audio.

Now this will make a 48k audio file and I think the CVD format calls for 44.1k audio but most DVD players will still play this kind of encoding from a CD without a hitch (assuming your DVD player can do VCD/SVCD then it shouldn't be a problem).

Since you used the DVD template it will be easy in the future to extract the CVD and copy it to a DVD once you get a DVD burner.

Thanks:
I actually have a DVD burner now but when I made the movie, it was split into 3 files. They were all 352x480 and I think the bitrate was CBR 2520. I only have a 21" tv so I doubt I'd see a difference between 352x480 @2520kbps and 720x480 @ whatever. Hence the CVD idea. I just demuxed all three and used SSRC to resample to 384kbps 48khz audio. I want to merge them all back together as one file and creat my first DVD.

Since you do have a DVD burner then let me suggest that in the future you try a slightly higher bitrate when encoding to Half D1 resolution. In my opinion it looks best at around 3500kbps (i.e., by looks best I mean looks best at or ABOVE this bitrate) and of course you should always to a 2-pass or multi-pass VBR in which case if you use an AVG of 3500kbps I would use a MAX of 5000kbps if not 6000kbps and a MIN of maybe 1500kbps although some seem to think it is fine to set the MIN as low as 0 (aka ZERO) while other people say you should set it to at least 300kbps. I however like to set it no lower than 1000kbps

Also note that Half D1 hits the MAX bitrate at around 5000kbps so going over that will not increase the quaity. I think 6000kbps is a good MAX though when doing 2-pass/multi-pass VBR but if your footage will fit onto a single DVD-R disc at a CBR of 5000kbps then that is about as good as you can get ... bitrate wise ... with Half D1 resolutions.

In fact I'm no "anal" about quality I do all my Half D1 encoding at a CBR of 5000bkps unless I need to use something lower to "make it fit" in which case I do a 2-pass/multi-pass VBR

Anyways ... you should see a difference RATHER EASILY between a CBR of 2500 VS a CBR of 3500

Remember no one ever said 2500 (or 2520) was the "best" bitrate for Half D1 ... it just is the BITRATE LIMIT of the CVD format just like SVCD which has a higher resolution but the same bitrate limit. This is due more to the structure of a CD-R disc I think than anything else.

So when doing Half D1 for a DVD-R disc don't be "afriad" to go higher than 2520kbps.
