I don't know about programming, so my recommendations may be totally wrong. Cinelerra is very good, but it lacks a well-functioning time-shift wizard. Today this effect is widely used. ReframeRT could be a starting point, but it is not the typical effect that a technician looks for. I really like the Premieres assistant and also the Sony Vegas assistant, which are the editors I know best. Thank you very much for commenting on your experience Igor.

Yes, I also thought the same thing. If were possible tecnically, it would be better and easier from point of view of an user. Another NLE, Lightworks_14, had done a good solution for me. Each track has a Speed text field that shows the speed of the clip where the cursor is on. When you change the speed of a clip, that clip will have that speed; you can not to do Speed ramp, for example.
In these days I am working on a Project that needs Speed fetures. To do that I use both ReframeRT and F_tmix plugins to create a fake SlowMotion (with Optical Flow) and then, with the Nest feature, I put the ClipSpeed in the Timeline. For some clips I have to use ffmpeg by command line and using "minterpolate" option to made OpticalFlow. Maybe there is Optical Flow in Cinelerra-gg but I do not know where. If anyone knows, He/She is welcome, please. I use Nest to avoid sync problem with the other edits on the Timeline when I use ReframeRT for the speed. I hope GG can make the Speed tool work well.
