Hi Maksym, did some more testing and ran into a couple of image quality problems. First, alpha blending seems poor, mostly noticeable with a text with curvy typeface over video: melt clip1.dv -filter dynamictext:Hello size=200 outline=2 olcolour=white family=elegante bgcolor=0x00000020 The first time you run that you will see that the alpha of bgcolour (black with 12.5% opacity) is not honored and the background is black. Set bgcolour=0 to make it completely transparent and look along curved edges to see the poor blending. The second problem is that key-framing opacity causes a repeating cycle of 100% A frame, A+B blended, and 100% B frame. The below reproduces it: melt color:red -track color:blue -transition composite out=99 geometry="0=0/0:100%x100%:0; 99=0/0:100%x100%:100" -- +-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
