Lazy Load or Thumbnail Usage With Videos in Masonry?

I have a page on my site that uses a masonry (love it) to format the layout of videos (via server connect API) that could be oriented horizontally or vertically. During testing overseas, the page loading of the videos took longer and as a result, the masonry updated the layout several times as the videos loaded into the page.

The masonry performed very well. The issue is the user experience; video loading causes the masonry to dynamically change the location/position of videos on the page. I looked into using thumbnails which is an option for images, but doesn't appear available in Wappler for videos. I also just read up on lazy load with dynamic data, but my concern is that videos not yet on the visible screen would again force layout changes as they loaded during scrolling.

Is there a way to set an initial height/width for the Wappler video element that is then overridden by the masonry? What other options are there? Using a CDN is a potential long-term solution, but not in the cards at this time. TIA
