Actually the problem is that the "model" which Cinelerra uses internally was designed way too simplistic right from start. Cinelerra can't capture the concept of two objects in the Session "belonging together". Moreover, all infrastructure to capture the "history" which led to a certain editing situation is lacking. Building either one of these things would IMHO be the prerequisite of solving that problem with audio-video sync properly. Unfortunately Cinelerra is a very powerful and flexible tool. There is a lot of things you can do with video and audio data. Consequently it is absolutely impossible to tell if a given situation in a session is "out of sync". Well, without breaking or missing some important corner cases, that is. Personally I did larger projects, where the sound was captured separately and synchronised with a flap. I used a bunch of python scripts plus quite some manual bookkeeping plus some very specific conventions to add the proper audio tracks after the image edit was in place. Basically this and a lot of similar experiences finally led me to jump into the Lumiera project (which, as some as you may recall, started out as an general overhaul of the Cinelerra code base).
