One of the most important features of all these tools is the rotation. Such a tool is only really useful if I can rotate the new mask from keyframe to keyframe. At the moment, I'd have to manually zoom in or out on each handle if the perspective changed.
I got the idea (probably wrong, given my incompetence) that to make rotations or other changes on the mask, the compositing engine of Cinelerra is not suitable. A completely new compositing engine would be needed to create matte on separate and independent alpha channels. That's why in an old email I asked if it was possible to integrate OpenFX, which would allow you to use a real rotoscoping tool, with all the features required by you and me in the ticket 02 of MantisBT. But I don't think it's possible: at least it means building a new compositing engine or completely changing what's already there.
You're right about that. The engine is somewhat limited. The rotation of objects in Cinelerra turns out to be difficult. Maybe OpenFX would be a help, but the OpenFX project seems to have fallen asleep. I haven't seen anything new in this project for some time. Maybe I'm wrong. I'm more disturbed by the limitation of the graphical means at Cinelerra. Guicast from Cinelerra is extremely outdated. But I can also understand that GG is waiting for more developers. As far as I have noticed, GG doesn't like to work on the graphical interface so much. I can absolutely understand it, everyone has his particular strengths and preferences. Kdenlive, for example, looks much better from the surface (the video and vector scopes lokk great), but is by far not as far advanced as Cinelerra. Nevertheless, they have a larger fan base because it is more modern and easier to use. I would only hope that a few more developers would get in touch and revise the user interface, i.e. bring Guicast up to date or alternatively switch to a more modern framework. At least the number of features increases from month to month at Cinelerra, which is really great. :) Sam
