How to improve the quality of HTML5 animations?

Hi,

I`m using Captivate 9.0.2 and publish in HTML5.

My problem: If I animate some object in Captivate (i.e. a rectangle or some other shape/graphics) the animation stutters, twinkles, falters etc..... It`s nearly never a "smooth movement".

I animate the objects directly in Captivate; however, if I import an animation (for example from Adobe Animate) the quality of the animation isn`t much better. I know that in general animations in HTML5 used to be worse than in Flash. However, nowadays there exist perfect animations - even in HTML5 (but not with Captivate).

The quality gets a little bit better if I publish with a frame rate of 50 FPS, but is still far from satisfying.

Does anybody know some tricks / hints how to improve the quality of animations in HTML5 with Captivate? I like to produce a professional course and it`s not very professional if it stutters like it does.

Thank you in advance!
