I tried 30p on disc. It looks fantastic on my player/TV, but who knows about compatibility across a range of TVs and players…

[Michael Spooner]

Thanks again. Do you have any recommendation for what length of motion blur would be appropriate to simulate film? Say, 00:00:00:06? And is Gaussian the preferable type for my application, or is it more a matter of taste?

[Michael Spooner]

Thanks for the input. I did switch my project properties to 24p, so that shouldn’t be a problem. Would you agree that I should rule out 30p?

So should I turn supersampling all the way up to 8 on the output bus before I render?

[Michael Spooner]

Gotcha, thanks. Do you know if both applications use the same conversion software?

On another subject–I’m trying to smooth out 24p to see if I can get it to have more of the smoothness of 30p (what I’d like to use if it were in the DVD standard, but I’m concerned about keeping things universally compatible). I’ve tried both motion blur and supersampling in Vegas. For my project (panning across still images) motion blur just seems to fuzzy things up and doesn’t really do much for judder. However, I think I can see a difference when using supersampling, although I’m confused… I thought that supersampling only had an effect when using motion blur? At any rate, is there any draw back (other than rendering time) to turning supersampling up all the way (8) throughout the project?

Perhaps I should start a new thread on this.

[Michael Spooner]

That makes sense. I would like to use AC-3, I’m just wondering whether the compression that DVD Architect uses is up to snuff, or whether it’s better to do the conversion with the Dolby Render plug-in inside of Vegas?

[Michael Spooner]

Thanks for that. Now I’ve got another sound-related question… Is there an advantage to coding AC3 in Vegas (at render) rather than importing wave files into DVD Architect and letting Architect convert them to AC3?

Some of my sound files are coming from Cakewalk Sonar and not going through Vegas at all, so I’d rather just convert them as the last step in Architect.

[Michael Spooner]

Thanks, that’s what I thought.

My only worry is that some players might not be able to interpret a 30p DVD. It doesn’t seem to be a common standard, and it has no template in Sony Vegas. I’m not sure if I should select the 24p template and then bump it up to 30fps (well, 29.whateveritis) or, alternatively, start with the 60i template and change it to progressive.

But I would love to do 30p. (Higher than 30p doesn’t seem to be an option at all, so I’ve ruled that out, I think)

[Michael Spooner]

I think he may have typed “CBR” in a few spots he meant “VBR”..?

[Michael Spooner]

Right. I understand that 24p with 3:2 pulldown is a standard DVD format, but I much prefer the smoother motion I get from 30p.

Basically, I want to combine the picture quality of 24p with the smoothness of 60i. In other words, 30p.

I do have a question on the subject of 24p, though. In the Sony Vegas Main Concept rendering options there is an option for either 23.976 or 23.976 + 3-2 pulldown. 23.976 + 3-2 pulldown is the default setting. What would happen if you switched it to 23.976 without pulldown? I was under the impression that the DVD player added the pulldown, so I don’t understand why you would want to add it during render. Or am I missing something?

[Michael Spooner]

Thanks for the further input.

While I’ve got you guys, I had another question regarding frame rate:

Is it possible to author 30p video to DVD and have it be compliant with the DVD specification? From what I’ve read, I get the impression that 24p is the only progressive standard that DVD will accept. Sony Vegas, for example, only has templates for 24p and interlaced at 30fps (60i). That being said, I burned a test DVD in DVD Architect with 24p, 60i, and 30p versions of my video, and it didn’t give me any trouble. When played back on my progressive scan TV, the 30p version is far and away the best of the three. There are NO interlacing artifacts, whereas the 60i still has some, and the motion is much smoother than 24p since there is no pulldown. When played back on a computer screen, there is absolutely no comparison between the 30p and 60i. 30p wins hands down.

My project is all still images with panning, zooming, etc done within Vegas so I can change the output frame rate and interlacing at will without concern over how the video was captured.

Disc space is not an issue, and I would like to get the best possible quality within the DVD spec. I like the progressive scan of 24p, but prefer the higher framerate of the standard 60i. Is 30p an option, or do some DVD players have trouble decoding it?
