Layout template catalogue

A layout template is a fixed arrangement of the frame that you choose up front. It is the inverse of the default path: instead of a model deciding every cutaway, the shape is settled first and the pipeline assembles it.

That trade buys three things — a video that looks the same every time, a flow with four steps instead of seven, and no generated code in the render path.

A model picks the words, never the layout

Inside a template the only open question is what a card says. Timing, position, size and code are all decided by the shape. Graphics are drawn by real components with typed props, so a card cannot fail to compile and it cannot wander out of its band.

There are currently 3 templates.

Split Screen

B-roll on top, you on the bottom

The shot never moves. B-roll holds the top of the frame for the whole video while you present underneath, and a stat or quote card drops into the bottom of the b-roll when it earns its place.

• B-roll: continuous — the band is filled for the whole runtime, because an uncovered second would render as an empty rectangle.
• Graphics: stat_display, quote_card, metric_ring, data_table, flow_steps — at most 4 per video

Rotoscoped Speaker

You, cut out, over a full-frame visual.

B-roll fills the frame. Charts and tables run the full width across the top. You are cut out of your background and composited over the bottom left, with captions in the space between.

• B-roll: continuous — the band is filled for the whole runtime, because an uncovered second would render as an empty rectangle.
• Cutout: you are matted out of your background and composited over the footage. Best-effort — if the matte fails, you render as a plain rectangle in the same place.
• Graphics: data_table, metric_ring, stat_display, flow_steps, quote_card — at most 5 per video

Cut-In

You stay on camera; footage cuts in below

You hold the frame the whole way through. When you name something concrete, footage slides up over the bottom of the shot, holds while you talk about it, and drops away again — and a headline takes the caption line when a moment earns one.

• B-roll: earned — a window opens only where the narration names something concrete.
• Graphics: title_card — at most 3 per video

Choosing one

If you want…	Use
Footage and yourself on screen together, throughout	Split Screen
To be the story, with footage appearing only when you name something	Cut-In
To stand inside the footage rather than beside it	Rotoscoped Speaker

What a template decides for you

Everything in this list is a question the seven-step wizard asks and the template answers:

• Aspect ratio and how many clips to cut
• Where b-roll goes and whether it runs continuously or only when earned
• Where graphics go, which kinds are allowed, and how many
• Where captions sit — the template overrides your caption preset’s margin, because your preset doesn’t know what band it’s being drawn inside
• Where your head sits in its band, solved once per take from the footage

Your brand still applies

A template fixes the geometry, not the look. Colours, fonts, logos and caption styling all still come from your brand kit and caption preset.

Using one over MCP

An agent can offer the catalogue with suggest_video_templates, which returns each shape with a link that opens the flow with your script attached. It suggests; you pick.
