Exporting pro res 4444 + alpha bug
Issue when exporting pro res 4444 with alpha directly from AE. When this file is taken into premiere, there are weird purple artefacts, this can be removed by changing the premultiply settings, but this looses some alpha and introduces black fringing. When the same comp is exported via media encoder, using the same settings, no such issue exists.

Hey Tim, how about you respond to the TOP voted suggestions since most have been sitting here ignored by your team? Do you even care that in each of these top voted requests there hasn't been a single word from your team? Or that each of those forums is filled with angry posts begging for your team to respond? Why does almost every other Adobe uservoice page have responses to their top requests but not you?

Pro Res 4444 renders that use Premultiplied alpha are being interpreted as Straight alpha, causing a black edge around the content.
