I think that you meant "H.264" footage.
How many Video Tracks w/ Clips, do you have in your Project?
With H.264 footage, the i5 CPU is going to struggle with playback, and the more Video Tracks you have, the tougher it will be to keep up with processing the H.264 CODEC. Also, with mixed footage, there will be a likely increase in CPU usage.
Maybe a Mac-user can directly address the issue for you.
haha yea that's what I meant. There are 3 tracks with video. Often stacked on top of one another.
ok I wonder if conforming the footage first would help? thanks
