Replace? my 2009 2.0 Mini 4gb Ram 7200rpm HDD for VIDEO

[gigaguy]

Not totally happy with video on my 2.0 Mini, esp with iMovie and higher res movie projects, (usually 720p). I see some jitteryness and slow down when working on some projects in iMovie. How much improvement would be gained with the newer Mini and a more powerful processor, or is iMovie the problem?
I have the previous 09 iLife. 4gb ram and Black scorpio 7200 drive.

my 2009 2.53 and 2.66 do a very good job with netflix 720p much better then my 2.0 or 2.26 did.

I have a 2009 2.26 and play 720p and 1080p bluray rips (with plex or quicktime) with no problem. How much ram do you have? I have 4GB and never come close to using it.

I have 4gb ram. I haven't tested it so much for playback, as much as in iMovie projects. manipulating short (2-3min) clips sometimes hangs and jitters. It could be iMovie more than my machine, but I wonder if a bigger processor would help. I have a 7200rpm Black Scorpio hard drive in it too.
thanks.

I don't use iMovie that much, sorry can't help you there. Pull up activity monitor next time your running a project and check cpu usage. Should give you a better idea of what''s happening in the background.
