Hi Dropzone,
Studio 11 and Version 10 as well decides that the first clip in your

will decide the record format. Therefore if you record your footage

on your camcorder in 16.9 format, any Title or 'Run-in footage

added to the start of your production must be in16.9 format as

well. If you have made for example a 'Wedding Title' at the

beginning of your film using a standard 4.3 format, this then

has decided that Studio will format the whole production in 4.3.

Hope this has explained your problem.

Best regards Snobbie45
