Customer-submitted videos are often recorded on phones at high resolution and uploaded without compression. A single 30-second video review can be 50-100MB — fine for a desktop on WiFi, devastating for a mobile shopper on cellular data. Uncompressed UGC videos are one of the most common causes of poor mobile product page performance.
The solution is to transcode all UGC videos upon upload. Target 720p resolution for mobile delivery (1080p for desktop), use H.264 codec for maximum compatibility, and aim for a bitrate of 2-4 Mbps. A 30-second video at these settings is typically 8-15MB — still watchable on mobile but dramatically lighter.
Serve different video qualities based on device and connection speed using adaptive streaming or simple responsive source tags. Mobile users on slow connections should receive a lower-quality stream that loads quickly rather than a high-quality stream that buffers.
Eevy AI automatically transcodes and optimizes all UGC videos served through its CDN. Videos are delivered in the optimal quality for each device and connection speed, ensuring fast playback without visible quality degradation.
