Video quality view — a positive ranking signal
Predicted probability of a quality video view. HARD GATE in code: videos shorter than the minimum duration earn ZERO video weight — the weight itself is zeroed, not just the probability.
Last public weight (2023 heavy ranker): 0.005 LEGACY-2023 — from the frozen twitter/the-algorithm; absent from the 2026 code.
2026 weight: withheld; gated by MinVideoDurationMs (value withheld) — all current weights live in an
unpublished params module. The weights story →
What actually moves it
A too-short video is scored as if it had no video. If you attach video, make it long enough to clear the gate and good enough to hold watch time (video_watch_time is a separate continuous head).
Where it sits in the formula
Phoenix (a Grok-1-architecture transformer, phoenix/README.md)
predicts P(vqv) per viewer from that viewer’s own
engagement history — not from your post’s running like-count. The prediction is
multiplied by its weight and summed with the other 21 terms, then the
author-diversity decay and
out-of-network multiplier apply.
