sort of. Actually this kind of curve is called a "bezier curve". It has the special property that you can influence the slope and curvature by dragging so called "control points". The curve reacts to this like a rubber band. It is a well known problem of cinelerra that the "discoverability" of this feature is bad, i.e. a lot of users never figure out that there *are* control points. Indeed, each segment between two keyframes has two control points. You need sort of "activate" these control points by dragging with the mouse while holding the "ctrl" key. Initially, they are located exactly on top of the keyframes, and because of that, you can't see them. > Is it possible to get a linear movement? yes. either by adjusting the control points accordingly, which is tedious. If I recall correct, the current verison of cinelerra has also a function somewhere in the menus, where you select a range and then can "linearise" all segments in this range. hope that helps Cheers, Hermann V. PS: several aspects of the handling of these bezier curves in cinelerra is clumsy and uncommon, compared to what usual graphics applications provide. Some years ago, I wrote an extensive patch set to improve some of these aspects. This patch set still applies to the current CV-version of Cinelerra (V 2.1). Unfortunately this patch set required me to change a lot of related and not so relate things, thus, due to the current development situation of Cinelerra it was never accepted into the CV-Version, (and I understand that quite well), because it would be an impediment to merge further changes from the upstream author (HV). _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
