So After being in these forums for a while, I was juggling between AIC and HDV from my Canon HV30. From what I had read, HDV was compressed and AIC was not. This in theory made AIC a better choice for rendering/output over HDV as the CPU was busy not going to be busy "decoding" the HDV and then outputting it. So the theory goes.... After a little trial and error on this one, I have found that AIC doesn't seem to do this. GRANTED, I am using external FW 400 drives for my media and my guess is that AIC's large HD footprint is what is really slowing me down. FYI: I use a intel iMac with 4 gigs ram along with said externals. So I guess this is a post just for some information, but does anyone have anything to say about this? Is my experiment flawed?
