I've got a Macbook Pro(mid 2012, Quadcore, nVidia 620/1GB vRam, and 8 GB of system Ram). Takes roughly 8-10 times the sequence length to render out video to a MPEG2-DVD file. I AM using Lumetri Looks in both cases but the Macbook Pro/AME seemsto slow down as time goes on. Checked the Activity monitor and using about 2.5 GB of Ram and only using about 1-5% of CPU.
Why isn't the Macbook Pro system not throwing more resources toward the render? (And no, nothing else is eating up the CPU either.) Also, rendering to external 7200 rpm drive so not a sytem drive either.
