Re: AJA HA5 Question -- OT

Hi Gary,

Thanks for your response. I think I should have been more specific.

When I display my Avid 1080 Color Bar .tif in the Windows Picture Viewer (in full-screen slide-show mode) the bars are perfect on my Black Magic Ultrascope. If I view those bars with the Windows Picture Viewer application title bar and scroll bars visible -- my luminence levels are illegal. Those PC graphic elements are the culprit.


When I view a Photoshop-converted JPG of those same bars in a browser like Firefox (which has no facility to eliminate the title bar or scroll bar (as far as I know) the same illegal issues crop up. And when I navigate to any website on the Internet -- the levels are similarly illegal.

My principle application for the AJA HA5 is to integrate web content into videos that I am cutting for specific clients. I will need to capture computer applications -- as well as websites, images and video off the Internet.

My original thought was to use the color bars as a way to determine that the output of my graphics card was in conformance with legal video levels. But the PC's desktop and application video levels do not match the color bars images.

If I use the nVidia Control Panel I have the option of selecting RGB vs. YUV dynamic range (0-255 vs. 16-235) but that has no effect. I can also selectively control brightness, contrast and saturation parameters -- but the video looks flat and dull when I do that. And, I'd rather not use the Avid legalizer to arbitrarily force the signal level into conformance.

My quandry is how to "setup" this PC's native display -- regardless of color bars -- so that I can capture computer applications, websites, images and video off the Internet -- and incorporate them into videos that I am cutting.
