# Type a two-line title on a white field so the block re-centres with every new character

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 "ChatGPT Computer Use: Now faster with Live Picture-in-Picture" (IYYTI73J7Rg), published 2026-07-10.
Source interval [517, 597) on the 24/1 fps master: 80 frames, 3.333333 s. Local frame 0 = source frame 517.
Create a 1920x1080 progressive timeline at 24/1 fps and a Fusion composition exactly 80 frames long. Keep integer frames; do not round the frame rate.
Background field: #f4f4f4. Export silent H.264 yuv420p to match the intended playback container.

## Observation
Hard cut to a soft white field with a faint vignette. A dark 46px semibold title types on character by character (~f2-45): the first line grows and keeps re-centring as it lengthens, then a second line starts beneath it and does the same until 'picture-in-picture' completes. The finished two-line block sits centred at mid-height and holds (~f45-79) before the next hard cut.

## Mechanism
Centre-anchored character type-on: the text block re-centres on each new character rather than growing from a fixed left edge.

## Phases (local frames)
- 0: White field
- 2: Line 1 types, re-centring
- 24: Line 2 begins
- 45: Both lines complete
- 79: Hold

## Layer inventory (absolute 1920x1080 top-left pixels, back to front)
- vignette [ellipse] at (-200, -300) size 2320x1680 fill #ffffff
- title [text] at (0, 480) size 1920x0 text "Desk mode is now faster / and shows a live preview window" 46px weight 600 #161616 reveal chars frames 2-45

## Construction steps
1. Timeline 1920x1080 at 24 fps; Fusion composition 80 frames. Local 0 = master frame 517.
2. Background #f4f4f4 with a large blurred white ellipse for the soft centre vignette.
3. Title: Text+ with Layout > Center alignment, 46px semibold #161616, line spacing 60px, two lines. Write On 0 -> 100% over frames 2-45 in character mode; because the layout is centre-anchored the block re-centres every character.
4. Hold from frame 45 to the end; the next shot is a hard cut.
5. Easy mistake: left-anchored Write On. The source anchors on the centre, so the first character appears left of centre and drifts leftward as the line grows.

## Content variants
Default copy:
- title: Desk mode is now faster / and shows a live preview window
Adaptation changes:
- title: Hands-free is now quicker / and streams a live picture-in-picture

## 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.
