yeah, indeed, that is due to a deeply rooted design decision in the existing Cinelerra codebase. My guess would be that this part has been designed from a developers point of view (because, when viewed from "within" the source code, it looks quite reasonable). But due to this decision, using keyframes precisely in Cinelerra very tedious. Basically, in Cinelerra a frame is displayed *after* the current position has passed over this frame. Moreover, any keyframe's values are effective for any time *after* the keyframe. It is indeed possible to get an instantanous change of Parameters, but you need to do it exactly in the following way: +----+----+----+-- K1 K2 ^Start of the new footage ^first frame of new gets visible There, K1 would be a keyframe with the old settings and K2 should contain the new settings. When working with this kind of stuff in single-step mode, the currently displayed frame is inconsistent with the above, but this is just the display. The same holds true when playing/stepping backwards (because then the direction of the logic is completely reversed). Again, rendering proceeds forward and finally that's what counts. hope that helps Cheers, Hermann V. _______________________________________________ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
