# Hard-swap a subtitle line so its black plate re-sizes to the new text, then clear it on the picture cut

Manual DaVinci Resolve / Fusion construction guide generated from the recipe. It is not a tested .drp.
The accompanying Remotion project (recipe.json) is the executable definition; the numbers below are copied from it.
Neither construction establishes source fidelity: this is an original vector approximation of an inspected editing moment.

## Source and clock
Reference: OpenAI's "Inside Cricket’s Smartest Backroom | Rajasthan Royals | ChatGPT @rajasthanroyals" (0XPk_MAwCW4), published 2026-08-13.
Source interval [3725, 3794) on the 25/1 fps master: 69 frames, 2.760000 s. Local frame 0 = source frame 3725.
Create a 1920x1080 progressive timeline at 25/1 fps and a Fusion composition exactly 69 frames long. Keep integer frames; do not round the frame rate.
Background field: #241a14. Export silent H.264 yuv420p to match the intended playback container.

## Observation
A seated interviewee in a dark wood-panelled room speaks to camera; at the bottom centre a short subtitle sits on a tight black plate. Frames 0-25 hold that short line. At local 26 (master 3751) the line swaps in one frame to a much longer sentence and the black plate is correspondingly wider, still centred at the same baseline. The long line holds until local 67 (3792), where a hard cut to a tight close-up of the same person arrives with no subtitle at all for the last two frames.

## Mechanism
Subtitle hard swap with a fitted plate: the plate width follows the text on the swap frame, and the subtitle is cut out with the shot rather than carried over.

## Phases (local frames)
- 0: Short subtitle on a narrow plate
- 26: Hard swap to long line; plate widens to fit
- 67: Hard cut to close-up; subtitle cleared

## Construction steps
1. Timeline 1920x1080 progressive at 25 fps; Fusion composition 69 frames. Local 0 = master frame 3725.
2. Shot A stand-in (frames 0-66): dark room with two wood panels and a bright gap, a navy jersey block with a red diagonal stripe and a head ellipse. Shot B stand-in from frame 67: a much larger head filling the right two thirds. Straight cut, no transition.
3. Subtitle A: Background 340x44 #111111 at (790,866) with a 24 px white centred Text+ at y=873; frames 0-25 only. Subtitle B: Background 500x44 at (710,866), same text style; frames 26-66 only. Both plates share the same vertical position and centre line x=960.
4. Size each plate to its text plus ~18 px side padding; do not animate the width. The change is a hard swap on frame 26.
5. End both subtitle nodes at frame 66 so the close-up at 67 arrives clean.
6. Easy mistake: keeping one fixed-width plate. The plate must hug each line, so the visible change at 26 is both new words and a wider black bar.

## Content variants
Default copy:
- lineA: so from there we lean on
- lineB: to sharpen how we bid on auction day.
Adaptation changes:
- lineA: and after that we use it
- lineB: to decide which players we chase first.

## Limits
Easing names map to Fusion spline shapes: linear = linear, in/out/inOut = ease curves on the same frames, hold = step, spring/overshoot = slight overshoot past the target before settling.
Text reveal frames give the first and last unit; distribute characters/words evenly between them. Cursor click rings last 14 frames.
Vector illustration is an approximation of layout and motion, not the product UI or recovered production assets.
