Premiere sometimes not rendering 4k MXF files from Sony FS5 I'm working in 4k for the first time.  I've got footage from a variety of sources, and I'm working on a 4k timeline (see sequence settings below).

When I try to render between In and Out points, I get the following error when Premiere gets to certain MXF files.  All the MXF files came from a Sony FS5 camera, shooting in one of the flatter "log" picture modes (can't remember exact setting).

It renders some of them fine, but some I had to reconvert into ProRes.

I'd like to work directly from the MXF files if possible.

I'm using a 2015 MacBook Pro 16GB RAM, OS X 10.11.6 with Adobe Creative Cloud 2015, Premiere version 2015.4 release, v.10.4.0(30) build.
