What problem does it solve? Website hero and background videos often fail in practice: they are too heavy, refuse to autoplay on mobile or Safari, throw codec errors, or look blurry on retina displays. This Skill provides a proven ffmpeg-based recipe to fix all of these issues when embedding footage you already have. ## Core Features & Use Cases - Probing and diagnosis: Inspect codec, pixel format, resolution, frame rate, audio streams, and moov atom placement with ffprobe before transcoding. - Web-safe transcoding: Convert source clips to H.264 with yuv420p pixel format, faststart, retina-aware scaling, and CRF-based compression, typically shrinking a 1080p screen recording from ~8 MB to ~1.5 MB. - Poster frames and embed markup: Extract a representative poster image and generate the muted/playsinline/autoplay HTML required for mobile playback, plus Odoo attachment serving guidance. - Use Case: A marketing site's homepage hero video will not autoplay on iPhones and weighs 8 MB. Use this Skill to re-encode it to a 1600px-wide faststart H.264 file, generate a poster frame, embed it with the correct video attributes, and verify playback via Chrome DevTools Protocol. ## Quick Start Optimize the attached video file for use as an autoplaying hero loop on my website and give me the embed code.
