Series drift is usually blamed on the model, the way a failed search is blamed on the catalogue. Check the filing instead. The character was described from memory at every job, and memory edits as it goes: “long mahogany hair” in the first frame becomes “flowing dark locks” three frames later, and the audience watches a stranger quietly take over the set. The repair is clerical, not technical. Write the character down once, on a card you paste rather than retype — an entry the rest of the directory is filed against.
Five fixed fields, always in order
A working finder card holds five things. Age — a number, always 25 or over. Hair — colour, length and one habitual style. Build — two or three words, no more. Face — one or two details that endure every crop. Signature — the mole, the ring, the mark that survives even a tight frame. Everything else belongs to the variable line: outfit, room, hour, light, pose. Variable lines are meant to change at every job. Card fields are not.
Two habits keep the entry honest over a long series. Fields are stated plainly and positively — “long dark mahogany hair in a high twisted topknot with one loose strand” survives generation, while “beautiful hair” is reinterpreted at every attempt. And the card is versioned. When the character is deliberately changed — a new cut, a new signature — the new text is saved as version two with a date, so an old set can still be remade exactly as it was first entered.
Working from the entry
Production then becomes a calm routine. Pair the card with variable lines that share one setting and one light, and generate the set at the standard model’s 6-credit cost. Keep the best third. Spend on repairs, transfers and upscales only after the cull. When a frame returns off character, the cause is almost always visible in the filing: a variable line contradicted a card field, or a field was too vague to be found by. Both are fixed on paper, at the desk — not by hunting through settings at the tool.
What a finder card cannot do
It cannot hold a character who was never decided. If the fields are adjectives — lovely, striking, perfect — no system in any directory will keep her, because there is nothing fixed to look up. Decide her on paper first. The finder card is not where the imagination happens; it is where the imagination is filed, frame after frame, so that months from now a new entry in the series can still be looked up against the very first one and found to be the same woman.
