Pixelated Video in Prototype

I have a Figma file that uses multiple videos, but there’s just this single 13MB, 2880x1620 WEBM video that appears pixelated when viewed in the prototype. However, the video looks fine when played directly in Chrome. I tried re-rendering it at different sizes and resolutions, then replacing the video in the Figma file, but the results are still pixelated in the prototype.

I’m seeking guidance on the following:

• Is there a size or resolution limit for videos in Figma that might be causing this issue?
• Does Figma automatically compress videos, and if so, is there anything I can do to prevent or minimize this?
• Could there be a Figma cache issue (I’ve tried ‘clear cache and restart,’ but it didn’t help)?
• Could the WEBM format itself be causing the problem? I chose it primarily for its smaller file size.
• Are there any other methods or workarounds to resolve the pixelation?

Thank you!
