You ignored Jon Barrie’s previous post, which was correct. In my experience, real time effects are possible with Matrox Axio (we have LE). Their suite of effects and many of Premiere’s transitions can be applied with no red line (render indicator). I don’t believe CPU’s can do all this work alone, even with a top-of-the-line video card.

The caveat is, as soon as you see you can play without rendering several color correction, time changes, scaling, etc., you say to yourself “OK, now I want dynamic linked AE comps and a couple of more layers of graphics and video.” And you’re back to the red line again. Kept simple, using only Matrox effects, you get true real time. And faster-than-real-time outputs in some, not all formats.
