OK, very close! But there is still one problem I noticed. On some geometry widths, the right edge of the B frame image is chopped off. This is reproduced in demo/mlt_my_name_is. On the first title that reads "My name is Inigo Montoya" notice how the right side of 'a' is cropped. -- +-DRD-+ ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ Mlt-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/mlt-devel
