What role does discrete graphics or the lack of it play in using iMovie and FCP?
I'm looking at a mid-level 2012 mac mini for video editing and I'm not sure if I will need discrete graphics. I'm new to mac so I want to see if iMovie can do what I need (basic edits of 5GB HD 1 hour long video files in either MPEG-2 TS Video (.TS), AVCHD Video (.M2TS), or MP4 Video(.MP4) formats).
Should I be concerned? What role does a GPU play in editing in iMovie? If the lack of discrete graphics slows things down, will it slow down importing, editing, exporting, or all?
