I’ve made an animation (only 21.8 kB), but when I play it the fps is very low. I’ve seen some Synfig animation where the animation is very smooth. And I was wondering if I could do anything to make it more smooth when I press play?
When you press play you play the canvas as is, Synfig has to redraw each frame, making it very slow.
You can render a preview to see how your work turns out and you can render a final film. try the clapper board and the projector icons in the canvas window.
