We work on the MAC platform. Our output workflow is; we render the preview files in ProRes 422, check all the renders on the timeline, then export a ProRes 422 file that matches the sequence settings. We export from Premiere (not to Media Encoder) using the Preview Files. This seems to give all the plugins a chance to work within the Premiere environment with very few surprises. It also gives us a solid ProRes Quicktime file to then convert to any file format we need.
For the original problem of MB Looks not being backwards compatible with the pre-upgrade renders, we just opened each timeline and re-rendered everything. It shouldn’t have happened with a plug-in upgrade, but it is done and we are moving ahead.
