Thanks for the response. When I got something working will put it here.
Have one more question. Is it possible to use scale and overlay filters with dynamic values of h:w for scale and x:y for overlay? like it is possible in setpts filter, 'setpts=AVTB/25*(N+0.05*sin(N*2*PI/25))' 2009/11/4 Stefano Sabatini <stefano.sabatini-l...@poste.it> > On date Tuesday 2009-11-03 23:05:52 +0200, Oleksandr Bondar encoded: > > Hello, > > > > I am creating video web editor where I work on video effects now.
