The type of video compression utilized for this kind of High Definition is significantly more demanding than the much less compressed HDV format you encounter on tape based HD camcorders. For instance I can have an hours worth of HDV open with multiple cuts, pastes etc. in Sony Vegas and have it all run perfectly smooth on my laptop. On the contrary if I open a 3 minute clip from my T3i, without any cuts, it will run choppy by the 3 second mark. It just chokes the system. A quad core is needed to edit and run seamless video. The video card matters too but they are not utilized properly in this scenario (with the exception being Adobe Premiere Pro CS 5.5's Mercury Playback Engine which enables GPU acceleration with certain graphics cards). All other software puts most of the load on the processor. A core i5 is probably the minimum worth using and an i7 would be better. It's a shame really because none of this extra horsepower would be needed if the software currently available could tap into even just a half way decent graphics card. Any Blu-Ray player has all the hardware necessary to play this kind of video smoothly (not that they are set up to do so - I'm just making the point that dedicated processing would greatly reduce processor demand). We are just at a point in time where these advanced video codecs got way ahead of the software to cope with them - so we have to throw expensive hardware at it in the meantime.
Great point and thanks for the input. It begs the question though. How many people are "fully" using the video capabilities of the T2i, T3i, 60D, 7D, etc... Video is a whole other discipline next to pure photography. Makes it kinda interested for a hobby photog like me.
