Render Queue Within Premiere
Premiere needs its own render queue for batch exports. Davinci Resolve has this. Media Encoder has been pretty inconsistent with quality. It always does something to mess up the image. Just let me export multiple things in Premiere if I want to.
Given that AME exists, it's unlikely that we'd add another render queue within PPro.
AME and PPro rely on the same rendering code; perhaps you could provide specifics about the inconsistencies you've found? Can you reliably reproduce the 'messes up the image' behavior? Happy to help further, provided actionable specifics...
