I have a intel i5 iMac with Premiere CS5.5, when I import a video shoted with a canon 60D in the timeline (without any edit or effect), it only plays abot 1 - 2 seconds of the video, and then it stops. In my old iMac (intel core 2 duo) the video plays. So, what is the problem?
Is there any way to play the video?
Do you have your footage on a Thunderbolt drive? Editing DSLR material on an iMAC with limited memory and only a single drive with such a CPU and GPU is very taxing for such a system. The system as such is just underspecced.
