I went back into a V7 project and rendered it with and without 32bit turned on. MiniDV source rendered to mpg2 at best quality. The differences are very small in the output but they can be seen. The dotted "i" was just a tad bit better (space between dot and base more defined in 32bit preference setting) and the yellow and reds in the background were brighter. 32bit took longer to render and for SD it might not be worth the extra render time. One of those things that you have to study and experiment with before making a decision or knowing when you will get the best results. I am rendering another veg file right now that contains a lot of text to see how it compares to the V7 output.

you've got to make sure you're using the right gamma curve too.

Just rendered out some DV Footage using the 32 bit float setting in properties. Perhaps its me but colour correction seems to have moved to a new level with very little tweaking its easy to get rich and beautiful pictures at least to what Im used to seeing in vegas.

Oh yes . .oh yes . . .

It has made my DoF even more effective too. 32-bit is more accurate, we are getting more from what we shot!

But I am having a time Previewing - sometimes down to er . . 13 fps and lower still .. 3fps?

Mark, I'll email you some stills . .

Grazie

"Color" me skeptical.

When you guys go on about how 32bit is just so wonderful, my alarm bells start ringing.

Unless previous versions of Vegas have been completely wrong in their handling of gamma, color, and whatever, then to my way of thinking throwing the 32bit switch should change NOTHING in the image except to eliminate quantization banding and other defects made evident after many rerenders.

If you guys are really seeing wonderful new color saturations and whatnot, are you thus telling me that prior to this, Vegas has been building faulty video files?

What am I missing here?

I dont know what your missing more to the point what am I missing then? Because definately Im getting better colours from the tiniest of tweaks. And thats a fact.

To me it looks like a mist has been removed revealing sharper more colourful footage underneath? A dramatic improvement.

It is NOT just the saturation on CC. See the depth of the water going away.

I'm not actually convinced this is a good thing. I don't want 32bit processing to change anything all on it's own. You need to have consistency between what you shoot and what you see.

In years of lighting, if I saw one thing in real life and something that different on the monitor I'd know the monitor was out of adjustment, and I'd always have been right.

So, when you two are using the 32-bit setting, which gamma setting are you using? If this is DV (or HDV footage, I guess) footage then you should be using the 2.222 setting, right?

It's really quite simple. Among other things, 32 bit floating point math processing allows a full scale RGB, ie from 0-255, instead of the 8-bit "Studio RGB 0f 16-235. Old DV cameras record in ITU601 color space. HDV cameras record in ITU709 color space.
This means nothing for NTSC displays, since they natively show RGB16-235 anyway(ITU601). But for computer displays, and HD displays(ITU709), the highlights and shadows show more "depth", without as much tendency to muddy or clip the details in these ranges. In addition to the increased latitude, a lot more depth to color mapping is possible. Consider the analogy of audio recorded at 8 bit, as compared to 16 or 24 bit audio. The dynamic range of higher bitrate is audibly enhanced. And so it is with the dynamics in the visual "scale" with 32 bit float.

This isn't "hype". It's real. Premiere Pro has it, all HD capable NLE's need to have it. If you have a camera that captures in 8-bit, you gain a small advantage. If your camera captures in anything more than 8-bit, you do yourself a BIG disservice by staying in 8-bit processing.

"If you have a camera that captures in 8-bit, you gain a small advantage. If your camera captures in anything more than 8-bit, you do yourself a BIG disservice by staying in 8-bit processing. "

C'mon - what sort of argument is this? I have a state-of-the-art, prosumer HDV camera (Sony HVR-V1E), and still am recording what the HDV standard allows me to (apart from expensive and unpractical methods of pre-tape HDMI capturing). Still don't know how 32bit is better - I can deepen the colours by adopting a gamma while shooting, or editing in Vegas 8bit.

Still waiting for the answer: when and how do I use the 32bit f.p. video?

after all the arguements I've heard on this forum about future proofing with HDV, NOW FINALLY there's someone who claims to not care about technology future-proofing. Excuse me, but, I GOTTA ROFL.

The people on this forum really make me shake my head in wonder.

Anyway, foolishness aside, if you don't like that arguement, you can
1-consider the improved bandwidth available from CCing, or
2-save your money stay with V7

Complete misunderstanding on your part. I assume there is a lot of progress and improvement in the 32bit processing, I'm just asking somebody to explain it to me how to use it. since the Vegas Pro 8 manual or help fail to do so.
