Performance / jittery page-load interaction when page has vimeo embeds

Hi,

I have a page-load interaction in which the headline / description of the page fades in and moves up on page-load. This works as intended on the 1st page of my portfolio site (as can be seen here: http://russell-prowse.webflow.io/work), but that page only has still imgs. On the 2nd & 3rd pages I have some Vimeo vids inserted via the video component and I can see they are being loaded initially when the page loads - & I think this then is making the animation halt for a few seconds and be very jittery.

Any ideas for improving the performance? Or is there any way to get the animation to fire after the vimeo assets have been loaded?

Here is the main problem page:
