Researching potential colorsync issues: mainly GPU enhancements

[Andrae Palmer]

Does anyone know how GPU enhancements are handled on the Mac? I see that many cards have features like noise & artifact reduction, edge enhancement and video deblocking. These enhancements are listed below:

1. http://www.techpowerup.com/reviews/HQV/HQV_2.0/7.html
2. http://hothardware.com/News/New-AMD-Catalyst-106-Drivers-Improve-Video-Playback-Gaming-Performance/

I want to know if those GPU enhancements are turned off on the Mac or if we can control them. I have no idea how to access those driver features on the Mac. Obviously if it's not disabled then there would be serious issues with using FCPX and a colorsynced rec709 computer display for proper monitoring.

On my PC laptop there is a pretty comprehensive ATI utility for managing the enhancement settings of the graphic card (Radeon 3470). Is there not a similar utility provided by ATI for the Mac versions?

Nope, there's no Catalyst for Mac, as far as I am aware. In Windows, most of these enhancements are "Application Controlled".

The good news is that the state of graphics on the Mac is far behind Windows, I would be surprised if these features are even available on Mac OS X, let alone enabled by default.

These are features that apply to the GPU's on-board video decoding capabilities. They're not filters that get applied to the entire screen image. Some of them, like edge enhancement, would seriously interfere with the proper display of sharp on-screen user interface elements (and text) if they were applied to the whole screen.

I doubt any of this stuff would be active in FCP X. Certainly not for formats like ProRes (which aren't decoded on the GPU), and probably not even for H.264.
