Each block is one HyperFrames sub-composition that rebuilds a row from a niche's steal list. The --hk-* tokens theme all of them at once, and variables set the text and timing. Hover a tile to play its demo, or tap it on a phone.

Styles
A style file holds the ranges measured across one creator's three videos, with the tokens, caption variant, blocks and mix presets that go with them. tools/scaffold.py --style starts a project from one; tools/check.py --style measures your render against it. Below: hard cuts per minute by segment, and the median shot length.

The ranges swing hard between niches: the documentary style opens at 24-48 cuts a minute and the explainer style at 0-4. Inside a niche, a higher cut rate didn't go with more views, so take a niche's rate together with its format.
How it was measured
Cut rate and loudness did not separate the outliers from their controls. A person at stake, the stake stated in the first seconds, proof on screen and a held answer did. Read both halves as hypotheses: each rests on three videos per creator.
There are 16 niches with one creator each. From a creator's latest 80 uploads we took the video with the highest views-to-median ratio, the highest ratio among the latest 30, and, as the control, the video closest to the median among the latest 30. Outlier ratios run from 1.62x to 44.32x and controls from 0.93x to 1.08x. Compilations, sponsored uploads, livestreams and anything over two hours were left out. Views were read on 26 September 2026.
Did not separate
- Overall cut rate. Outliers cut slower than their control in 4 niches and faster in 4, and every faster case has a confound. Johnny Harris's outliers: 14.6-14.8 cuts/min, his control 23.4.
- Median shot length, which follows the cut rate.
- Integrated loudness: -5.6 to -33.9 LUFS across the 48, with no direction.
- Designed transitions. 15 of 16 niches use no whip, glitch, spin or zoom as a habit, in outliers and controls alike.
Recurred in outliers
- A person with something at stake: 6 niches.
- The stake or claim in the first seconds: 6 niches.
- Proof on screen: 5 niches.
- The title's answer held back: 4 niches.
- Denser speech in the first 30 s: 8 niches.
- Fewer music-only stretches: 8 niches.
What each number is
- hard cut
- An ffmpeg scene score of 0.30 or more on a 160 px wide copy. Detections under 0.25 s apart count once.
- segments
- Long form: 0-15 s, 15-60 s, 60-180 s, the body, the last minute. Shorts: 0-3 s, 3-15 s, 15-60 s, 60 s on.
- text share
- The share of sampled frames where Tesseract reads two or more words at confidence above 70.
- words per minute
- From the YouTube caption track, over the whole video and over the first 30 s.
- loudness
- EBU R128 integrated loudness and loudness range, measured with ffmpeg.
- silences
- Stretches below -35 dB that last 0.4 s or longer.
- music
- Spectral-flux onsets, brightness and bass share in 10 s windows, and
[music]tags in the captions.
Hard-cut counts are floors, since dissolves, whips, camera moves and overlays go uncounted. Every niche is one channel's house style. Nobody listened to the audio, and tempo under narration was too unstable to use. Views don't prove an edit caused them. The full tables, the confounds and a mood table are in research/TECHNIQUES.md.
