It is still exporting as 4:3
I shot using DVCAM wide on a HDV Sony
edited as anamorphic and the frame size in the sequence says 720 x 576
it PAL format
export using current frame size makes it 4:3
in QT conversion, mpeg4, my frame size options are:
160x 120
176x 144
320x 240
352x 288
and no option for a custom frame size
