Controller for Keyframes

So I don’t know how to do… most things in Synfig. For example, the mask I made is literally just a transforming shape that covers a portion of the outline of Beastboy’s ear. I also don’t know how to duplicate all the elements of his head.

But what I am wondering is if anyone can tell me if it might be possible to make a controller that can control this headturn. Very very preferably it would be a horizontal slider.

I’d love eventually to rig the eyes and eyebrows too. And use a switch(?) controller for various mouth shapes. But that’s for later on. Hopefully. If I can get that controller working. Any help would be amazing thank you!

Here are some tutorials:

  • Synfig Video course playlist (it uses an old version, but most things are the same way):
  • Khemardi’s tutorials:

    • Basics (according to him)

  • Advanced:

Thank you, I know there’s a lot of videos and I’ve watched them several times but I was wondering if I could get some help from the community as my eyes are kind of burned out from watching the tutorials at this point and documentation doesn’t seem to cover character rigs

I can’t seem to view the video. Would it be possible to convert it to WebM?

I’m not actually at my computer for the next few hours but are you able to view it from the streamable link? Watch synfigstudio_8gvYZdOwlG | Streamable I tried so hard but couldn’t get it to less than 3MB OTL

Why not to keep it on Youtube? Even as “Unlisted” ?
Uploading videos on the server make it heavier and even Streamable is buggy (and deleted after 90 days)

Never really use private upload on YouTube but just did it there. I tested on a private window so hopefully this link works 31 July 2026
