[Mlt-devel] filter geometry attached to clip is relative to start of track

2012-12-13 Thread Brian Matherly
Dan, There is an interesting behavior when a filter that uses a geometry is attached to a clip. See the following example: melt colour:blue out=100 colour:red out=200 -attach dynamictext:"#timecode" geometry="0=0/0:100%x100%:100;100=400/500:100%x100%:100" The expected behavior would be: 1) 10

Hello everyone, When I create a video with some background color and text overlayed on it, some kind of jagged edges appear around the text when I view video in full screen. Here is the script that I have used to overlay text on background color, colour dynamictex
