Quick Fix for NitroPack Display Issues on Fast WordPress Site

详细信息

Need help adjusting a few display issues that appeared after optimizing my video production site with NitroPack. The site loads incredibly fast (99% on mobile/desktop), but we have some visual quirks to fix:
Issues to Fix:
Video Shape Problems
Case study & About page videos display as squares (should be landscape)
Videos taking too much vertical space
Homepage Loading Glitch
Brief static image appears before hero video plays (only when coming from other pages)
Browser-Specific Issues
Problems appear in Firefox/Safari/Opera (Chrome works fine)
What We Need:
Minor CSS adjustments to fix video dimensions
NitroPack configuration tweaks
Solution that maintains current loading speed
Cross-browser compatibility fix
