I would want to edit 1080p@60fps@28MBps footages (from an action cam).
My laptop have a Intel Core i5 5200U CPU and 4 GB RAM. Also, there's a dedicated AMD Radeon graphic card.
First, I must wait for the rush to be "charged" in the timeline in order to play normally.
Preview a transition is laggy (even when the two footage are "charged" in the timeline).
And preview effects (mostly speed effects for slow motion) is a pain.
Is it a video quality problem relative to my configuration?
If yes, what is the bottleneck: RAM or CPU (tell me it's RAM, I can add some more).
