Optical Flow
Optical Flow Interpolation
An AI-based method for generating new frames by analyzing pixel motion between existing frames for smooth slow-motion.
Technical Detail
Video optical flow follows standard aspect ratios: 1920x1080 (1080p/FHD), 2560x1440 (1440p/QHD), 3840x2160 (4K/UHD). Bitrate requirements scale roughly with pixel count — 4K at equivalent quality needs ~4x the bitrate of 1080p. For web delivery, adaptive bitrate streaming (HLS/DASH) serves multiple quality levels based on network conditions. Most viewers watch on mobile screens where differences above 1080p are imperceptible, making 1080p the sweet spot for web video delivery.
Example
```html <!-- Optical Flow: HTML5 video with format fallback --> <video controls preload="metadata"> <source src="video.webm" type="video/webm; codecs=vp9,opus"> <source src="video.mp4" type="video/mp4"> Your browser does not support HTML5 video. </video> ```
