BUG: No trimming occurs when consolidating Amira-footage, unless LUTs are completely removed
This means consolidating a sequence with Amira-footage will not discard any footage, and the whole operation is useless. All LUTs must be removed to make it work as it should.

Amira-footage is ProRes422 - on a Mac. My workaround now is to export an xml, import it into Premiere Pro 2014, where all LUTs are removed, then export it as xml back to Premiere Pro 2017. Then all Amira-footage gets trimmed. But I also discovered that clips from Sony FS7 (mxf-files), all in the same sequence as the Amira-footage, is still not trimmed regardless of any LUTs.
