What the system keeps track of from one segment to the next

Quick answer: Every segment is still generated on its own, from the character, scene and prop images and its own storyboard text; the clip before it is not shown to the video. What carries the story across the join, in storyboards written or regenerated since late October 2026, is a running record the site keeps while it reads your text: who is in which scene, whether they sit, stand, lie, kneel or crouch, what is in their hands, which look they wear, wounds and mud on their body, whether they are wet or unconscious; and for each scene the time of day, weather, light, doors and windows, and whether a crowd is there. Each new segment starts from that record. You change it by writing the change in a shot, in the shot where it happens.

Not sure which kind of storyboard you have? The segment header, field by field shows both layouts. Older storyboards work differently: why the next segment opens like the last one ended.

What is in the record

AboutWhat is remembered
Each personWhich scene they are in · sitting, standing, lying, kneeling or crouching · riding something · what they hold · which look they wear (a state image, if you made one) · marks on the body (blood, bruises, scratches, burns, mud, dust, sweat stains) and where on the body · wet or dry · dead or alive · unconscious or not
Each sceneTime of day · weather · the light · whether doors and windows are open or shut · which look the room is in (for example after damage) · whether a crowd of passers-by is there
Each objectWho is holding it, or which scene it is in · which look it has
Who is next to whomWhen two people stand together and one walks away, the other stays where they were

It remembers what is still true when the shot ends, not what happens during it. A smile, a flinch or a half-second reach for a glass belongs to that shot’s text and does not carry over.

How a change gets into the record

Write it as a plain event in the shot where it happens, as you would in a script. The record changes the moment the text says so, and stays changed until the text changes it back.

You write, in segment 3Segment 4 starts with
@Mara takes off her coat and lays it over the back of the chair.Mara without the coat; the coat on the chair
@Leo is hit across the face; blood runs from his left eyebrow.A cut on Leo’s left eyebrow, still there
@Leo washes his face at the sink.The blood washed away
@Mara slumps to the floor, unconscious.Mara lying on the floor, unconscious

Reverse the change the same way: she puts the coat back on, the cut has healed, he wakes. If the text contradicts the record — a character who died walks into a later shot — the text wins and the record follows it, so a mistake in your wording does not break the segment.

What you can see and change in the editor

  • Time · Weather on the segment header, with Change, applies to the whole run of segments in that scene. Segment header.
  • In frame under the text shows who each shot will show. Notes under a segment.
  • State images for looks that last: a torn coat for the next five segments is a state image, not a sentence you repeat. Costume changes and scene states.
  • Video edited appears when you trim a clip or change its visuals; later segments then continue from the edited clip. Edit this clip.

What it does not do

  • It does not show the video the previous clip. There is no last frame attached to the next segment, which is why you can generate segments in any order and why regenerating one never changes the next.
  • It does not invent what you did not write. If someone is hurt between segments and no text says so, the record has no wound. Put it in the first shot of the segment where it should show.
  • It does not decide framing. Whether a segment opens on a close-up or a wide shot is in the first shot’s text.
  • It keeps the record per character. Say who the change happens to: use the character’s name or the @ chip in the shot.

When something does not carry over

  1. Find the shot where the change should have happened. Is it written as an event (she is cut on the cheek) or only implied (her cheek looks bad)? Write the event.
  2. Read the first shot of the segment that lost it. A line there that says otherwise (she walks in, unmarked) overrides the record.
  3. If the look should last for many segments, make it a state image and pick it for those segments.
  4. Save, and generate the segment again. Editing the text is free; the record is re-read from the new text.

Segments you generated before the change keep the video they have; only segments you generate afterwards use the corrected record. When a shot comes out wrong · Shot-to-shot continuity.

FAQ

Does the next segment see the clip before it?

No. It starts from the images and its own storyboard text, plus the running record of the story. There is no last frame attached.

What exactly does the system remember?

Where people are, whether they sit, stand, lie, kneel or crouch, what they hold, which look they wear, wounds and mud, wet or dry, unconscious or not; for scenes, time, weather, light, doors and windows and crowds.

My character's bandage disappeared in the next segment.

Write the injury as an event in the shot where it happens, and check the first shot of the next segment does not say otherwise. For a look that lasts, use a state image.

Does it cost credits to update the record?

No. Editing the text is free; you pay only for the video you generate.

Why does a character stay where they were when I did not move them?

The record keeps people where the text left them until the text moves them. Write the move in the shot where it happens.

Is this the same for ads and remakes?

No. They use the older way, where each segment starts from its own text and images.

Do older storyboards work this way?

Not unless you regenerate them. Storyboards written before late October 2026 keep the earlier behaviour.

Can I see the record?

Not as a list. You see its effects in the Time and Weather line, the In frame note and the images each segment uses.

Write the change where it happens.

One sentence in the right shot is all the next segment needs.
