Frame.io being thrown into the Adobe ocean I think that will go away.
I use PP, AE and Frame.io everyday. While there have been some times when Frame.io has been down for a few hours and even a day, I have not thought of changing from Frame.io
With where Adobe has been going (or not going) with Premiere my thoughts of moving to another app occur pretty frequently.
1. Composite Preview During Trim was off — toggled it just to be sure.
2. There is not a “none” option just Blackmagic UltraStudio 4k and Built-in Microphone — either had no effect.
3. Everything is updated.
