Overlay mapper
Copies an existing video's on-screen text onto the remake: same words, timing, positions, sizes and colours, without inventing any.

already-extracted on-screen text from a real video into precise render specifications for a text
renderer, so the replicated video shows the same text the original did.
SOURCE ANALYSIS (verbatim, extracted from the source video — do not alter the wording)
{{sourceAnalysis}}
The replicated video is {{format}}, {{lengthSeconds}} seconds long; the source's timings have
already been scaled to that length.
WHICH TEXT TO MAP
Use the onScreenText entries of every scene. Reproduce only kind "message" and kind
"disclaimer". Brand wordmarks/logos ("logo") and award seals ("badge") are graphic marks —
re-typing them as plain text looks cheap and dated, and brand presence already comes from the
product/logo reference image — so drop them. Also drop animation fragments: a short text that is
just a prefix or part of a longer text in the same time window (e.g. "PAIR" vs "PAIRED WITH 20
MINUTES OF EXERCISE,").
CLUSTERS
Texts whose time windows overlap appear on screen together, so group them into one CLUSTER. Each
cluster becomes ONE overlay: a single transparent graphic onto which SEVERAL text elements are
composited, each keeping its OWN position, size, weight, and color — exactly like the source frame
(e.g. a big headline, a small corner tag, a badge, and a fine-print footnote all at once). The video
model accepts a limited number of reference images, so use at most 8 overlays: if there are more
clusters than that, merge the closest-in-time neighbouring clusters until the count fits. Merging
never drops a text; it only co-locates texts that are near each other in time. A cluster runs from
its earliest start to its latest end.
TASK
Produce one overlay entry per cluster, in chronological order. For each cluster, output an
elements list with ONE element per text in that cluster, in reading order. For each element:
- description: a complete render spec for that single text. Include the quoted text VERBATIM
(unchanged wording and capitalization), a screen position, font size in pt, bold/regular,
text color hex, outline color + px, and padding px. When the text includes
fontStyle/fontColor, reproduce them (map the described weight/case to bold/regular, use
the reported color's hex); only infer plausible styling where the source doesn't specify.
HARD RENDERING CONSTRAINTS (the renderer is simple — violating these breaks the output)
- One element per source text — never merge two texts into one element, never split one text
across elements, never drop or invent text.
- POSITION each text by the ZONE its role occupies in a real ad, honoring the source's own
placement first. The valid anchors are exactly: top-left, top-center, top-right, center-left,
center, center-right, bottom-left, bottom-center, bottom-right. Conventions (use unless the
source clearly differs):
· Lower-third identity — a person's NAME line plus their TITLE/ROLE line: give BOTH the
SAME anchor (normally bottom-left) AND the SAME padding, so they stack as one flush-left
block. The renderer stacks same-anchored texts in reading order, so the earlier text
(the name) sits on top and the title beneath it. Keep the name larger than the title.
NEVER scatter a name and its own title to unrelated anchors (e.g. name bottom-left, title
center-left) — they must read as one unit.
· Spoken-line subtitle / primary caption → bottom-center.
· Legal fine print / disclaimer → a bottom corner (usually bottom-right), small.
· Big headline / product claim → center.
· Brand super / tagline → top-center.
Texts that occupy DIFFERENT zones must get DIFFERENT anchors so they don't fight for the same
space; only texts that form ONE visual unit (a name with its title directly beneath it) share
an anchor so they stack together.
- Size each element to its role: headlines large (~40-48pt), sub-lines medium (~28-36pt),
disclaimers/footnotes small (~14-20pt). Keep a single line to ~40 characters at 44pt / ~50
at 36pt on a 1280px-wide 16:9 canvas (fewer on 9:16 and 1:1) — if longer, choose a smaller
size rather than truncating or altering the wording.
- Always specify a text color hex AND an outline (2-4px) with strong contrast so the text is
readable on any footage — white #FFFFFF with black #000000 outline is the safe default.
- On a 16:9 frame (1280x720) the frame is only 720px tall, so keep vertical padding small
(top/bottom padding ~70-110px). On 9:16, keep text out of the top ~14% and bottom ~20%.
- Do NOT write any font name inside any description — font is controlled separately via
primaryFont.
FONT
Choose ONE primaryFont for the whole video from the fixed palette below — whichever best
matches the source's on-screen text style, using the texts' reported fontStyle (serif vs
sans, weight, case, condensed vs wide, script vs geometric) as your guide. Every element uses
this same font (do not vary it); the renderer applies it uniformly.
PALETTE (grouped by style, for matching):
neutral/corporate sans — Liberation Sans, DejaVu Sans, Roboto, Open Sans, Lato, Inter
geometric/rounded sans — Ubuntu, Quicksand, Montserrat, Poppins
condensed/display impact — Bebas Neue, Oswald, Anton, Archivo Black
serif (editorial/luxury) — Liberation Serif, Playfair Display, Merriweather, Abril Fatface
script/handwritten — Dancing Script, Pacifico
Match the source's actual look: bold all-caps condensed headlines → Bebas Neue/Anton/Oswald;
thin/heavy geometric sans → Montserrat/Poppins/Inter; classic serif → Liberation Serif/Playfair
Display/Merriweather/Abril Fatface; cursive/handwritten → Dancing Script/Pacifico; otherwise a
neutral sans. Only pick script or single-weight display fonts (Bebas Neue, Anton, Archivo
Black, Abril Fatface, Pacifico) when the source text is clearly styled that way — they have no
separate bold/italic cut, so they render identically at every weight.
If the source has no text to map, return an empty overlays list.
