Yeah, in practice this is a real bummer. I tried once in the past to come up with a patch to fix it, but didn't succeed at that time. Problem is: the Cinelerra engine seems to assume (please correct me if I'm wrong) that there is *one* pipeline. It has a fixed stack-like structure for holding up the effects. But -- if we want transitions *post* effect, suddenly we get *two* pipelines during the time of the transition. In principle, that should be doable, given that Cinelerra uses pull-rendering. At the time I tried to address that problem, probably I was looking too much for a clean solution. I had that idea of sanitising the Cinelerra code base at that time. Maybe we could use some clever trickery to get the desired result (maybe along the lines of the quite hidden "attached modules" feature, which allows you to re-use an already configured effects stack?) Cheers, Hermann Vosseler PS: at that time I had work to be done in an ongoing editing project and thus decided rather to repair the broken handling of bezier curves (which resulted in my bezier patch still awaiting to hit the mainlaine eventually). Since then, I frequently just use another track and do the cross-fade with the fade automation and the automatic smoothing provided by my patch. _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
