I think you have to remember that the Amiga was designed to work with video and because of this they went the Pal/NTSC route.
PC's have never done video well even to this day I can run circles around most PC video editing software programs with my A4000 Video toaster. Unless your willing to buy the big ticket video editing packages that cost over $8000 you wont come close. I use a Toastscan flicker fixer and that works great with a PC monitor unfortunately LCD monitors look poor as the Amiga uses the NTSC resolution.
