[David Roth Weiss] “There is a problem under the hood of Premiere with the XAVCi codec – as best it was explained to me, a Premiere needs to be “optimized” for many, if not all, new codecs, and XAVCi hasn’t received the treatment yet.

I haven’t been impressed with XAVC performance in PPro at all, even though FCPX takes time to “unwrap” the footage, performance is significantly better with it on my system.
I hope this is fixed soon!
