Label
Small white italic — the thing being measured: «rental cost», «floor area».
AI headlines
Headlines that carry the point, not the transcript
Subtitles repeat every word. A headline says the one thing the viewer must take away — and holds the screen while it matters.
Open the editor →How a headline is built
- 01
Speech is aligned
Word timings come from forced alignment, so every word on screen has its own moment.
- 02
Blocks are chosen by rules
Prosody and the scene graph decide where a block starts and what it is built from — deterministic, no network needed.
- 03
AI writes the wording
The model turns the phrase into ad copy: «RENTAL COST», «NEW WALLS». It is a headline, not a quote.
- 04
Layout places it
The layout engine computes coordinates in the upper third, clear of faces and objects. The model never returns a pixel.
Three roles, one composition
Value
Large white caps — the answer the label sets up.
Accent
Oversized colour — the number or word the whole block exists for.
Count-up
Numbers roll to their final value with an ease-out, so a figure lands instead of appearing.
Why it reads differently
Words fly in one at a time in the order they are spoken, roughly a word per second, and leave the same way. The screen is never asked to hold a paragraph.
Between blocks the frame goes empty for half a second or more. That pause is part of the format — without it the text flickers and the viewer stops reading.
A block is two or three ragged lines with their own sizes and offsets, not one centred string. It behaves like a title card, because that is what it is.
Where headlines beat subtitles
Specs and numbers
Price, area, wattage, deadline — the label→value pattern is what this mode is built for.
Sales videos
The offer, the benefit and the condition stay on screen while the voice moves on.
Expert explainers
Terms and figures get a visual anchor the viewer can hold on to.
Silent viewing
The point survives with the sound off, without a wall of caption text.
Headlines or subtitles
Subtitles are for comprehension. They repeat everything, so a viewer who lost the audio — or the thread — can catch up on any word. That is why they win on long-form, on interviews and anywhere accuracy matters more than pace.
Headlines are for retention. They show up rarely, hold two to four words, and force a choice about what actually matters in each stretch of speech. On a fifty-second vertical video that choice is the whole edit.
The formats also fail differently. Too many subtitles read as a wall and get ignored; too many headlines read as flashing and get skipped. The density budget — roughly a word per second, with an empty screen between blocks — exists to keep the second failure away.
You do not have to pick once. Run headlines over the hook and the numbers, subtitles over the explanation, and let the layers hand off. Both are timed from the same alignment, so they never fight for the same moment.
Yours to change
Every block lands in a storyboard tab in the editor. Rewrite the line, switch a word between label, value and accent, drop a block, or turn subtitles back on underneath. Nothing is locked to the model's first answer.
FAQ
Yes. Headlines are a separate visual layer — you can run them alongside subtitles or instead of them. The reference format we designed against uses headlines alone.
