Pixel accurate output to SDI?
Anyone any good ideas how to achieve a pixel accurate output on SDI?
Output setup will be:
Catalyst DVI Out (800 x 600 75Hz)
to Folsom ImagePro SDI
from here via SD-SDI to LED-Wall.
My Problem is that the 800 x 600 output will be scaled down to 768 x 576 with matching centers.
If my content moves by 1 pixel it will move less than one pixel on the LED-wall - that means I will get a pixel interpolation (2 pixel active at some percentage of original brightness)
What I will try to do is to scale the image on the ImagePro up and only use the top/left 768x576 pixel of my 800x600 input.
This will require quite alot of manual setup on the ImagePro but should work in theory...
Anyone any better solutions ?
Why pixel accuracy? On LED walls you will achieve better edge contrast and smoother slow movements.
