Playout in realtime just to get desired format....

It's like going from London to Brighton through Manchester

Would rather export to other format (eg. Cineform, DNxHR) and convert with tool which supports ProRes- AME etc.
When you do many masters anything other than direct export is always waste of time and storage.
Had to edit 150x50min masters (add new bars/clocks+slates and few black gaps at 'correct' place for commercial needs) and deliver as ProRes. If I had to deal with extra conversion then that would annoy me for sure, so I did not use Resolve, but Premiere (with some automated 'editing' to save extra time). It was done in few days. Already thinking how to make it even faster next time.
Same applies to mentioned DPP export. Without proper integration (marker based segmentation etc.) it's fine with MC plugin, but only of single masters.
