Shows concrete wins: a 59s video drops from ~50 MB to 11.13 MB from codec change and lower bitrate (reported bitrate 6,697 kbps to ~1,500 kbps). Recommends tools and fixes: use Chrome Media panel, set video width/height to eliminate CLS, prefer an optimized poster or detect whether LCP uses poster vs first frame, remove unnecessary audio tracks, put WebM/vp9 first then MP4 for fallback, and adopt HLS/DASH adaptive bitrate playlists. Mentions Cloudinary automates codec, quality, poster extraction and reduced a 192 MB asset to ~64 MB.
