Hi Rafael,
Thanks for your reply.
I am exporting for color mix, so what you suggest is to export as 4:3 interlaced from Export > QTM? Not 16:9?
Whichever way, when I export through QTM as anamorphic or as current settings (like my sequence in FCP) the result in Quicktime property inspector shows the ACTUAL export as 1049×576, and when I try 4:3 the result shows 789×576.
I appreciate any further comments, many thanks, Tomas.
