<div dir="auto">IgorV pointed out that while our manual still describes multiple projector keyframes/boxes in compositor it doesn't (reliably?) work this way, namely I think I created second box somehow but can't reproduce :)<div dir="auto"><br></div><div dir="auto"><a href="https://cinelerra-gg.org/download/CinelerraGG_Manual/Compositor_Keyframes.html" rel="noreferrer noreferrer" target="_blank">https://cinelerra-gg.org/download/CinelerraGG_Manual/Compositor_Keyframes.html</a><br></div><div dir="auto"><br></div><div dir="auto">"Move the projector slightly in the compositor window to create a
keyframe. Then go forward several seconds. Move the projector a long
distance to create another keyframe and emphasize motion. This creates a
second projector box in the compositor, with a line joining the two
boxes. The joining line is the motion path. If you create more
keyframes, more boxes are created. Once all the desired keyframes are
created, disable automatic keyframe mode."</div><div dir="auto"><br></div><div dir="auto">small video describing how it worked inĀ cinelerra-cv 1.2.1 using old dynebolic 1.4 iso</div><div dir="auto"><br></div><div dir="auto"><a href="https://m.youtube.com/watch?v=08UCImr82CE">https://m.youtube.com/watch?v=08UCImr82CE</a><br></div><div dir="auto"><br></div><div dir="auto">I wonder how "long" must be long distance? offscreen? tried this, also with enlarged projector range .... no two boxes! I can't even see this behavior in cincv 2.3.* from 2017, but may be I am doing it wrong for all versions?</div></div>
