I queried Red Giant support. They just responded on "when and if" they would be adding a version that works with Vegas Pro 14. Seems certain that my PluralEyes 2 and 3 will never work with Vegas 14. This is a blow! For now I'll have to use the workaround of using PluralEyes with VP13, then copy into VP14.
From the response at Red Giant, I'd say it would help if others quiered on the same subject letting Red Giant know we want to use PluralEyes with VP14.
" ... ..we don't retroactively (update) older versions of our products for compatibility with the latest host application releases (such as PluralEyes 2 and 3 with Vegas Pro 14).
I couldn't give a definitive timeframe on when that'll get added to PluralEyes 4 specifically; we're aware of the lack of compatibility but, since adding it involves collaboration between our team and the new Vegas owners, it's going to take time. I'll add you into the request system to hopefully give it some weight in development .... "
