What is STUDIO RGB and do I need it? 8 bit 32 bit?

[mikecazzx]

In an ongoing effort to under exactly what I am doing, I came across a blog post that said to use Studio RGB and to use the pixel setting 32bit and not 8 bit.

If I add the Color Corrector effect and switch to Studio RGB it seems to increas the blacks and the saturation a lot. Is this right is this wrong? Is this only used if it is going to be on the web?

Do I do a different render without Studio RGB for my own Bluray?

How does this all work? Is there a right and wrong way?

If I create a new project and use a source file from GH1 for the properties it reads in pixel: 8 bit. If I use 32 bit in the editing it looks great in the editor, but still renders out the same as it was at 8 bit. What is this all about and why isn't 32 bit better or sticking on render?

if anything, Studio RGB decreases contrast, while Computer RGB increases it. I've always preferred Studio RGB myself for burning BluRay...but again, it's a preference in my case.

as far as the 8bit/32bit thing...hopefully help will be along shortly...

I am looking at it now. studio-computer rgb makes everything pop with high contrast -------computer to studio makes everything washed out with a grey film over the image. The stock footage from the GH1 seems to fall between the two, but closer to the washed out look.

ok...maybe i read your initial statement backwards

well, i suppose then it depends what your piece is destined for, but if it's going to broadcast, there are many other variables to making it legal.

for everything else, just use your eyes. if it looks good to you, then soldier on!

you're right, depending on the film mode you use with your GH1, footage may lack contrast or appear washed out. a lot of users prefer this as it gives them a "clean slate" to begin color correcting.

Studio RGB is for broadcast. Computer RGB is computer viewing.

It's a little more complicated than that, but that's the easiest way to describe it.

The upshot is that if you shoot video with a 7.5 IRE setup and want to have it viewed on a computer screen, Computer RGB helps make the colors and contrast better.

Conversely, if you have video meant for computer display and want to take it to broadcast or DVD, Studio RCB helps.

This is getting interesting. So one could say render one for web viewing and render another for dvd and bluray? This would be a minor slow down, but what has me scratching my head is color correction? Clearly Studio RGB looks way different and I would be making decisions in Vegas based on the Gh1 file properties upon project creation.

Also how can I find out if my shots from the GH1 are 7.5 IRE?

Well, yeah. There's no one-size-fits-all render. You render to best fit your intended viewing.

This would be a minor slow down,

But it's what you have to do if you want the best results.

Part of it is personal taste and what you want the image to look like in the intended viewing format. If it's just for your own viewing and you're happy with it, then it's all good.

But there may also be requirements imposed by whomever you're delivering footage to.

Also how can I find out if my shots from the GH1 are 7.5 IRE?

I don't think there's even an option; it's always at 0 IRE. A 7.5 IRE setup is for North American NTSC SD.
