I have a iMac Pro 3.2 GHz, 64GB ram, Raedon Pro Vega 56 8 GB, and I am working with 7200 RPM Thunderbolt 2 drive, and it is just stuttering and lagging playing back my 4k and 1080 video. I'm currently working with a 1080 sequence that include 4k footage shot with a Sony A73. As soon as I add any keyframing for motion everything pretty much just stops. I am still on CC2018. 1. Is there an ideal sequence setting that I should work with that may playback footage more smoothly? Should I be just dragging in a clip into my sequence and set it up that way rather than choosing a sequence preset? 2. I need to add warp stabilizer to some clips, and do more keyframing though I am afraid to because it makes scrolling through the timeline almost impossible. Should I do this all at the end? Can I apply the effects and turn them off with the FX button so it doesn't apply them or will that still slow things down? Any other tips? Thanks.
