Animation options are grayed-out for video object when it is a "Video from Website"

Hi Developer Ignition,

Thanks for reaching out with this question!

I'm happy to help provide some insight on this. You are correct that the option to add an entrance or exit animation to a video inserted from a website is grayed out.

One option to try is to add a slide transition, such as Fade. Here's a quick preview of adding a slide transition to the base layer:

I hope this helps! If you have additional questions, please let me know!
