I’m shooting with a T2i & I had some .mts files from a Canon HF 10 which I initially converted to QT in CS4 encoder. FCP didn’t like some of those files & crashed when I put them in the timeline. I wound up converting the .mts files to QT using iSkysoft. I eventually made single Pro Res movies out of each camera. They are about 100gb each, I’m thinking this was a mistake to make such big files. There are spots on my timeline that hang up for several minutes. I’m also having problems with sound partially disappearing from dvds that I’m outputting from FCP.
I just noticed that apple isn’t listing my new i7 iMac for sale on their web site, only the i5 & i3!?!
