Smooth gradients

Slow four-colour gradients with almost no high-frequency detail. Banding introduced by an over-aggressive transcode shows up as visible steps.

Switching rendition keeps the current position and the paused state, so the same frame can be compared across the ladder.

HLS

Multivariant playlist with fMP4 segments, four second target duration, EXT-X-PLAYLIST-TYPE:VOD. The CODECS attribute of each variant is read back from the encoded file rather than assumed, because an overstated level makes some players refuse a rendition they could have played.

Safari and iOS play this natively. Chrome and Firefox need a player such as hls.js — see the HLS notes.
