i"m doing research on HDV system for PC. Fristly I thought Edius NX was the only best for HDv realtime editing. BUt i just find out the new Matros RT.X2 few days ago.
I'm so confused about the difference between of them.
Rite now I only see that Matroc Rt.x2 can do better than EdiusNx:Full-resolution HD monitoring on an inexpensive flat panel display via independent DVI output.
