32-bit video signal path
Posted by Jerry Waters on August 30, 2007 at 4:57 pmSo what is “an industry-leading 32-bit video signal path” for Vegas 8? Douglas, I saw you made a comment about, “You’ll first want to understand the difference between processing bits and color bits.” Please explain.

August 30, 2007 at 8:48 pmThe discussion you’re referring to is seriously out of whack; it’s confusing.
So, without all the rhetoric and academia…
Here is an original file and here are the resulting SD MPEG files from the original file, the *only* difference being 8 bit vs 32 bit float in the project properties.Douglas Spotted Eagle

August 31, 2007 at 4:26 amWOW! Thanks for the example. These days I shoot in HDV, which I assume will benefit from this. Will my old DV footage, shot with a three chip camcorder and obviously with the bad 4:2:0 / 4:1:1 conversion issues also benefit from this?
Looks like 8 is going to be an instant must-have for us “instant must-have” personalities. Hopefully Sony won’t screw me over the way they did with the upgrade to 7, where they dropped the upgrade price by $100 a few weeks after the release. It was annoying to be screwed this way for being a band-wagon-jumper.

August 31, 2007 at 11:14 amSo Douglas, what the ad is saying about 32 bit is in processing – like After Effects has but it is still not a 10 bit program like Premiere, right?
So “Surpass traditional 10-bit standards with 32-bit floating point video processing.” is like comparing apples vs. oranges?
And the “improved video monitoring,” does it preview 1080 any better? How much better? It get awfully aggravating wondering if your audio got out of sync, having to ram render. Does it get close to Cineform Prospect in Premiere? Frankly, it may be better but mostly with the titler. My biggest reason to upgrade is that I heard at NAB that the only beta testers of 64 bit would have to be upgraded to 8.

August 31, 2007 at 11:29 amAs I think about it more, I think the Videoguys ad is deceptive in trying to intimate that 10 bit editors are behind an 8 bit editor working in 32 bit float. All they are really saying is that most 10 bit editors don’t have a 32 bit float. They are still 10 bit and produce more. (And they can get 32 by going to AE if they need it.) Let’s get real and really produce the 64 bit program that utilizes the processors, speeds preview, works in 32 and is 10 bit. Vegas is the most intuitive editor with the most effects and can work with or produce any kind of file but it is falling behind. It’s time to catch up.

Same thing happened to me with the version 7 update. But, I called customer service (an oxyMORON) and they credited the $100 back to my credit card. I don’t know if it is too late now but I would certainly try!

August 31, 2007 at 9:24 pmPerhaps redundant adding the following since the reference page may already be known by some of you, but figured I’d so so anyway.
I stole and shortened what follows from one of my recent postings at the Creative Cow Particleillusion forum (I feel 32-bit float will help with PI files imported into Vegas also).
______________________________From Vegas Pro 8:
32-bit Floating Point Video Processing“Surpass traditional 10-bit standards with 32-bit floating point video processing. Take advantage of greater color range for more vivid colors, reduced gradient banding and posterization for smoother color transitions, linear light capability for optically correct compositing, and many other precision enhancements.”
………………………………………
The keyword is “processing” — and not output. Meaning that your project settings will determine the end result as rendered files, but while in the kitchen, you’ll get spicier work done 🙂
A Bit More on Higher Bit
For more in-depth understanding of higher bit process, see the article on Creative Cow about a competitor’s 32-bit float color processing (Adobe Premiere), and why it matters in overall editing.
A bit techie but supports what I see as a boon to PI + Vegas users since Vegas has now incorporated a similar engine.

August 31, 2007 at 9:28 pmJust to clarify, the 32bit processing benefits users regardless of output format, if they’re using a format that can benefit from 32bit, such as HDV.
I posted links earlier to files ingested as HDV, output as SDMPEG, one using 8bit and the other using 32bit. The difference is staggering.Douglas Spotted Eagle

March 4, 2008 at 2:31 pmIs there a special codec for viewing these Mpeg files? I am unable to see them.
