Aspect Ratios and DVD Architect

Hmmmmm.

Don't know. I won't be able to look at it any more tonight, but nothing I can think of off the top of my head would cause that. 24 IRE would be something like values of 55 in the RGB.

I have you tested changing the DVD setup, if the black bars created in your player will differ
from the black bars created from your display?

Sending a 4:3 signal from your player, is often better then sending a 16:9 signal, if the display is 4:3 itself.
 
So I set up my external preview to go to the dv camera I use to capture with, which I hooked up to the television for a timeline/DVD comparison. The 16 16 16 is definitely darker in the timeline than it ends up on the DVD, which leads me to believe there's something in either the render or the burning that is altering the black. Also, 16 16 16 seems VERY close to the DVD's black, but it still seems just slightly off. But it's so close, I doubt you could tell a difference. And the RCA cables may be the cause of the slight difference there.

I'm gonna render/burn another test and see what happens.
 
A-ha!

Okay, I just put some letterboxed DVDs in my computer (The Little Girl Who Lives Down the Lane [MGM] and Ghostbusters 2 [Columbia Pictures]); since the computer can display 0 IRE, the 7.5 IRE letterbox part is obvious. So I used the Pick Color from Screen option and found that the values for those titles aren't 16G 16B 16A, but 16G 0B 16A. On my television, those lines bleed in perfectly with the default bars. So I'm about to render and burn a 16 0 16 test and see how that works.

Hot dawg, this is exciting.
 
Setting blue to 0 would give you a dark, dingy yellow. Not sure that would be good.

I don't know why you're having the problem you are -- all the steps you've taken should have worked.

Maybe you've done something with your graphics card display settings? It *shouldn't* matter, but possibly your video settings are affecting it? (Doubtful.) Or, maybe, and I doubt this is the problem, either, but are you on Windows 2000?

Maybe try a re-install of Vegas.
 
I'm on XP.

I am using 32 bit editing. Could that be the problem?

Anyway, here is a screenshot of my black:

It seems to be correct according to my waveform. Do you think Architect could be doing something to it?
 
Okay, I just went to preview in DVD Architect with a rendered out file created using 16 16 16. I used Pick Color from Screen to see what it labeled the letterbox bars as. It said it was 29 29 29.

So could Architect be the problem here? Or maybe some setting in the mpeg2 render options is off?

Seems like I'm getting closer to the real problem here.
 
Okay...this is weird but problem solved. I rendered a file without any underneath letterbox black bars whatsoever; that is to say: I left it at 0 0 0. So then I took it in Vegas and previewed, used Pick Color from Screen again and it showed up as 16 16 16. !?!

So I burned that...and...it worked. So it seems that Architect (at least version 4.0) accounts for ignorance and bumps your black up to save your ass. So...it's weird that you don't have to do it but I tested it and it works and I'm tickled.

Thanks for all your help, though.
 
And I just tested Pick Color from Screen with that burned disc the way I did The Little Girl... and Ghostbusters II. Sure enough, it gave me 16 0 16.

So I'd say problem solved, case closed, amen.
 
The 32-bit floating point color space may INDEED be what the difference is.

EDIT: Indeed it is. The problem can be solved with the 16, 16, 16 values by choosing the 2.222 (video) gamma instead of 1.000.
