There seems to be a slight flicker once the animation is finished. This only seems to happen with HTML Videos. I was unable to reproduce the effect with other elements such as divs or imgs.

 

Has anyone come across this issue before?

Thanks for the demo. Very strange.

I really don't know what that is. It's gotta be something the browser is doing as I've looked in dev tools and GSAP is setting the right values.

 

 

Here is a side-by-side comparison with another video tweening to autoAlpha:.99 and another tweening to opacity:1. It seems that as soon as opacity hits 1 there is a slight jump.

 

video 1: autoAlpha:.99 (no jump)

video 2: autoAlpha:1 (jump)

video 3: opacity:1 (jump)

Update: only seeing this on Chrome (Mac). FireFox and Safari fine.

Yep, weird browser rendering bug. Could just animate to opacity:0.999 to work around it. Not ideal, I know.
