Wondering which Mac hardware to buy for video editing/encoding. I'd like to take about hour of movie I shot with my camcorder, edit in iMovie, then encode/burn to a DVD to send to family members. I've done this with my Dual 1ghz G4 QS, and it takes several hours (7 to 8 i think). Would the new iMacs or the current MacPros do it that much quicker? Any idea how long for one hour of video to encode/burn to a DVD? Should I use Toast or another third party app rather than iDVD? I've heard that its really a problem with the G4, and that even G5s do this much faster. I'd like to think the new iMacs would be fast enough, or if I should hold out for new Macpros (Oct?). Thanks for any help!
