I think that's the way your're supposed to solve the task. -- Hannes ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
[CinCV] Can EDL type information be seen in GUI somehow?
I don't see any way in the interface to know whether or not a piece of video has been trimmed. Am I missing anything? For example, if I add a second clip immediately after the original one, and then want to add a 5 second transition, I need to make sure that the first asset has 5 seconds of video that's been trimmed from the end, to cover the transition period. I don't see any way to know that without actually noting the end time, dragging the end point and seeing if it expanded, and then "undoing" if I changed something that was already OK. Is there a better way to know how much, if any, video exists before and after a segment?

I'm so excited, because I think I know the answer to this :-) Select the range containing the keypoints on the curve and then in the main menu there's a "Straighten Curves" option, I believe under the Keyframes menu item.

Re: [CinCV] Type of movement between curves point
Paolo Valtorta schrieb: > In the timeline curves (fade, camera X, camera Y, etc) the movement between > points is a sine law (I believe). 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 Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra

[CinCV] Speeding up and slowing down a track
Hi, This is a creative/usage question rather than a compilation/installation issue. I've got a track that I want to add a fast play effect (double speed) for the first 6 seconds of input resulting in 3 seconds of output, followed by the next 2 seconds of input slowed down by 0.5 to produce 4 seconds of output, then play the rest of the track a double speed. I've been experimenting with the Reframe RT effect but after several hours of playing I can't seem to get the effect I want. Trying to achieve this with a single video track produces jumps in the sequence. I've made slightly more progress by splitting the track into three separate tracks and applying the Reframe RT with the appropriate settings each track. Hopefully someone else has already tried this and can provide some hints on how to achieve what I'm trying to do. I'd be more than happy to document this by way of a wiki page once I get it sorted.
