Exactly.

Yup!

Nope!

The issue is: who do you target? Mac users or PC users? If PC users, you'll do nothing to the gamma. If Mac users, you'll want to decrease the gamma by 0.4. Unfortunately, neither platform is smart enough to understand the source colorspace and compensate accordingly. :P

Ben - it sounds like if my main market is web viewed on Windows, I should adjust the gamma of my Mac monitors to follow the Windows gamma? Does that sound reasonable?

Now if I can just figure a way to calibrate my hdmi output from FCP to 24" Samsung 245T (rather neat monitor, hdmi, dvi, rgb, s-video inputs).

I forgot to figure how I was going to calibrate the hdmi input, as my GretagMacbeth Eye One Display has no desktop or mouse on that monitor when receiving output from FCP thru hdmi.

Always something!

Ben Syverson December 6th, 2007 03:05 PM

Les, FCP will adjust the gamma automatically to 2.2 while you're editing. What I'm unsure of in whether Compressor will apply that gamma when you output. I don't believe it does, but I could be wrong... In that case, you'll want to adjust the gamma when outputting using Compressor.

clothing for green screen
 
Hi Ben
Other than the obvious ( green ) what color and type of clothing should I tell the talent looks best for keying.Look forward to getting your new software as will doing much green screen in the near future.
Thanks, Aldo

will new dvMatte Pro work in Motion
 
Ben - will the new version of dvMatte Pro work in Motion? Thanks!

Scott Aubuchon December 21st, 2007 08:31 PM

As far as the whole gamma issue (PC/Mac), I have found a solution... Well, at least a reliable way to display.

The new flash player can display H.264 movies. I have embedded a .m4v and .mov that look spot on (as far as gamma)... across all platforms and browsers.

The only downside, the player update is very new, so not everyone has it yet... but they will.

Ben Syverson December 22nd, 2007 05:33 PM

Aldo, most colors should be fine. Anything in the green range will get obviously get desaturated... You may want to be careful with yellow as well -- it might be best to shoot some tests if you need to protect yellow.

Les, the new version does indeed work in Motion (2.0 and up) and FCP (5.1.2 and up)!

Scott -- good to know! Thanks for letting us know what you wound up doing.

Ben - I gather the video tutorials are the hang-up for the release of dvMatte Pro 3.

Any chance on posting a quick demo from the creator using:
http://www.ambrosiasw.com/utilities/snapzprox/

showing the proper use of the plug-in along with Screenfix, etc?

BTW - this thead is missing messages posted after Dec 22.

Tutorials are the Delay
 
Les,

The tutorials are the delay. I posted it to the main forum, but it got bounced off. The talent is ill, so until that person recuperates, they're holding off the launch. DVGarage is a small company, and you can only launch a product once (in theory). Being sick is no fun, so hopefully they get better soon.
Best, Anthony Torres
(fwiw-I called for the straight scoop.)

Hey guys,

Yeah, Alex has been sick, and then I had some problems ensuring the demo versions would work in FCP 5... I did record screencasts for the beta test, and those might find their way online as well, I'm not sure. Regardless, I'll be recording some screencasts once we launch to show people some more advanced techniques.

Stay tuned!

Scott Aubuchon January 25th, 2008 09:50 PM

quick question... I have dvMatte blast, is it more efficient to use in final cut or motion... or does it not matter.

When I say efficient, I guess I mean quicker. Seems like it takes a while to render in FCP, but I have not done much testing in motion. (waiting on my new mac pro to ship)

Any insight would be great.

Les Caudle January 28th, 2008 09:20 AM

Ben - I use ProRes 422 HQ. I've just realized that ProRes has no alpha channel, which kind of blew me away.

What is the best workflow to move between FCP and Motion, letting each do what it does best? Almost all of my clips will be green screen.

Ocean Zen January 28th, 2008 11:03 AM

I bought a BlackMagic Intensity Card to capture HDMI output from my Canon HV20 whilst recording green screen footage

I have a Mac Pro with Final Cut Studio2 and planned on capturing to ProRes422

What codec would you recommend? I would prefer one that I don't have to pay for.

Les Caudle January 28th, 2008 10:19 PM

Ocean Zen - If you were asking the question of me, I've been recording in ProRes with no issues, but I'm trying to come up with a workflow to go back and forth between FCP and Motion.

I don't think filters make the trip, so stripping out the background in a 1st step and generating a new file seems to make sense.

But then, I'm very new at this and was hoping someone with more experience would chime in.

Maybe FCP7 (sometime this year??) will add another ProRes codec - or Apple could add this to Quicktime anytime they wanted for more power.

Or - maybe a CineForm solution is the way to go?

Ben Syverson January 29th, 2008 01:52 AM

Les, you should be able to roundtrip between FCP and Motion without rendering, so codecs shouldn't come into play.

Ocean Zen -- ideally, capture to Blackmagic's uncompressed codec. You payed for the card, so you might as well get true uncompressed footage from it! :)
