Pixelation, 2-pass rendering in Vegas VS DVD author program
-
Well that certainly makes sense however since this is a 2 1/2 hour project in Vegas…is there really anyway to make it “truly” DVD compliant since the DVD authoring program needs to compress it down to fit? I must’ve rendered from Vegas at least 10-15 times all different ways to try and prevent the DVD authoring program from doing it again…but I think the length is killing me. Sadly DL DVD’s aren’t an option because this film needs to be duplicated and distributed to people and the blank DL DVD’s are too expensive. I also have cut the film down as lean as I possible can…in fact it was almost 3 hours long initially and I chopped a half hour out of it.

*Postscript:
I should add that I only use Verbatim blank media. I realize there’s probably cheaper DL DVD’S but I am devoted to Verbatim for my projects. -
I shoot stage productions and 2 to 2.5 hours is not unusual at all. You use a bitrate calculator to determine your VBR bitrates, plug those into Vegas and make the MPEG and AC3 files for DVDA.
It just occurred to me that you are probably including the audio with the video file which is in no way DVD compliant. Which is why your authoring program is re-encoding it.
Why aren’t you using DVDA?

Hi There Stephen,
Thanks again for your replies and your time. Yes you are 100% correct. As soon as I import the MPEG-2 the authoring program makes me change the audio to Dolby Digital before it will accept it. As shamed as I am to say this…the reason I don’t do it any other way is because I don’t know how. I know, I am shamed but I don’t know how to do it that way sadly. I am still learning many new things in Vegas, thanks to this great site and reading through some of the threads. -
It took me ten years to not feel like a newbie. I am a slow learner.
Do you have DVDA? I have made hundreds of DVDs using DVDA with no problems.Steve Mann

Hi Stephen,
I don’t have Architect, just Vegas. TNPGENC is quite good, I just don’t know the ins and outs of it in too much depth. So a lot of my problems aren’t the program, it’s user error, especially after reading all this great advice here.
Anyway,since my last post I opened my master project. I set the render template as instructed by Mike above…Your bitrate is far too high for a 2.5 hr. video.
I used Mark’s Bitrate Calculator and got the following numbers:Low: 2,104,000
Avg: 3,512,000
High: 6,152,000This assumes AC-3 for your audio at the default of 192.
For this long of a program a 2-pass render is, IMO, a necessity.
Use the DVD Architect NTSC video stream template (24P and widescreen are options as well) and customize it.
Now I notice there is an option in the audio tab to “include audio” which I assume is meant to be unchecked since you mentioned I have to render just the audio separately right?
So I used the DVD ARCHITECT NTSC VIDEO STREAM TEMPLATE. I set my bitrate exactly as Mike said. Anything else I should do before I hit the render button? Also I assume after the video is rendered that I have to then render an audio file AC-3? I assume that’s straight forward then? Just pick that output during the rendering?

Yes, “Include Audio” should be unchecked. I also use Mark’s Bitrate calculator, and I tend to round down. So if Marks says a Max of 2,104,100 bps, I enter 2,104,000 into Vegas. Mark’s rate and my rounding down has been good for me in most cases. Once in a while, maybe one time out of ten, I have to tweak the max down to make the files fit on the DVD without DVDA trying to re-encode it.

Thanks Stephen…so here’s the scoop.
I just started a render with these exact settings…Used DVD ARCHITECT NTSC template
Set bit rate for
High 6,100,000
Avg 3,500,000
Low 2, 100,000No audio
Checked “Use 2-pass”
Rendering as Main Concept MPEG-2.
Am I doing okay so far? LOL!

Just an update Stephen:
The video file described above (I haven’t heard back so I hope the settings are right on it) has fully rendered. I am now rendering the AC-3 audio. However there were two different AC-3 options. One of them wouldn’t work unless I installed DVD Architect…the other (I think it said “AC-3 studio”) does work and that’s what is rendering as I write this. Am I doing everything right so far? Thank you!
