Adaptive Bitrate Ladder Builder
Build a sensible ABR rendition ladder for a source resolution — the rungs (resolution + bitrate) a transcoder should produce for smooth adaptive streaming.
Adaptive streaming needs several renditions so each viewer's player picks the best their connection can sustain. A good ladder spaces rungs ~1.5–2× apart in bitrate down to a low mobile rung. Bitrate scales a bit faster than resolution (the ^1.4 here) because lower resolutions compress more efficiently per pixel.
