Gnonlin is aimed at "easing" non-linear editing. It does not handle effects and sources by itself, just like GStreamer core is media-agnostic and concentrates on efficient multimedia graph-handling. Simple cuts work. If you want it to cut to black, set a default black video source (using the videotestsrc element) and gnl_composition_set_default_source(). To do video fade-in, for exemple, you have to add a black source (using the videotestsrc element) which overlaps through time with a higher priority than you video source, and then add a videomixer element with a smaller priority (hence more important) during the desired fade time. To sum up what works well with gnonlin: * element positioning through time * taking parts of a source (setting the (media_)[start|stop] properties correctly) * applying effects on (one or several) source(s) * Synchronized composition outputs The next phase is working on making gnonlin even less cpu-intensive, which is going to be improved a lot thanks to the upcoming GStreamer 0.9 release, and adding live non-linear editing (being allowed to add live sources, and modifying the timeline while it's playing). > > Nice to see that CVS repository alive again after all these years.
