is 16gb ram enough for video editing macbook pro

Using the camera original (an H264 clip) in a Sequence created by dragging and dropping the clip onto the New Item icon and then exporting to H264 Match Source - High Bitrate resulted in the 'Analyzing in background' banner being rendered into the exported clip and no Morph Cut transition. The macOS is 10.12.6 Sierra and Premiere Pro is CC2017 (11.1.2). I tested this out on my 11-inch MacBook Air (Early 2015, 8GB RAM, 2.2GHz i7, Intel HD Graphics 6000 1.5GB integrated graphics) with 2160p30 footage shot on my iPhone. Although, this is definatlely plan B as the third party effect is somewhat pricy and the process takes some time to setup, track, adjust and then render (however, you can get exceptional results). There's a trial version of the effect available for download and you'd want to watch all fo the tutorial videos (I think that there are 12 and it'll take about two hours to go through them) to master how the morph effects is controlled in AE.

Prior to Morph Cut, this is the approach you would have had to have taken. If Premeire Pro just won't do it on your machine, you could aslo try Revision Effects RE: Flex morph effect in After Effects. I'll try to do a Morph Cut on my 15-inch MacBook Pro (and older 2013 model) with 4K footage and report back with what happens. If you're still having issues using Morph Cut, one option would be to downcovert your 4K camera originals to 1080 Apple ProRes. Then create Apple ProRes 422 (Proxy) proxy files, enabling the Proxy workflow in PR. You're on Mac, right? Try transcoding your 4K camera originals to Apple ProRes422 (HQ) (unless you're tight on disk space, then use Apple ProRes422 (LT).
