Recently I have been playing around with the wonderful mac video editing software, and iMovie HD no longer fullfills my need. I would like to have something that provides more feature like filters, rendering effect... etc. I am making a documentary film and requires blurring people's face or name of the places, which software provides this feature ? Motion 2 ? Final Cut Pro 5.0 ? or iMovie Express HD ? *p.s. I am trying to avoid Final Cut Pro 5.0 since it is too much money for me. Thanks in advance.
