My daughter has asked me to put some video and stills from a mobile phone onto DVD to send to her in-laws in Holland for Christmas. The stills look fine, and so does the video that was shot "Landscape"

BUTTTTTTTTTTT

Several video clips were shot in Portrait mode, and no matter how I try, I cannot get rid of a big black bar down the right hand side of the frame.

I have set Project properties to the DVD output, and with each of the "Portrait" clips, I have used Pan/Crop to Match Output Aspect, and chosen the best part of the "vertical" video frame to put in my frame.

In the Pan Crop Window it looks fine - the resolution allows me to zoom in without losing quality, and the dotted lines are all within the shot video frame, but in Preview there is a thick black bar down the right side. Even if I zoom in well clear of the shot frame edges, the black bar remains stubbornly static no matter what I try.

Does anyone please have any idea what is happening here?

Thanks for any help.
