# Clear a four-word title right half first, left half two frames later, then fade in a two-part lower third

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 can now complete tasks on your computer" (dB6pOolO7io), published 2026-07-16.
Source interval [128, 200) on the 24000/1001 fps master: 72 frames, 3.003000 s. Local frame 0 = source frame 128.
Create a 1920x1080 progressive timeline at 24000/1001 fps and a Fusion composition exactly 72 frames long. Keep integer frames; do not round the frame rate.
Background field: #d6d9d5. Export silent H.264 yuv420p to match the intended playback container.

## Observation
The four-word staircase title and its bottom-left sub-line sit over a presenter at a desk. At ~f15 the right-hand pair of words and the sub-line vanish together; two frames later (~f17) the left-hand pair vanishes, leaving clean footage. After an 18-frame pause a small lower third fades in at the bottom-left (~f35–f38): the name on the left and, with a gap, the role to its right on the same baseline. It holds to the end.

## Mechanism
Two-beat title clear (right group, then left group) followed by a single-baseline name-and-role lower third fading in after a pause.

## Phases (local frames)
- 0: Title and sub-line hold
- 15: Right words and sub-line off
- 17: Left words off
- 35: Lower third fades in
- 38: Hold

## Construction steps
1. Timeline 1920x1080 at 23.976 fps; Fusion composition 72 frames. Local 0 = master frame 128.
2. Title: reuse the five Text+ nodes from the type-on study (84px semibold, sub-line 34px) at the same positions, fully revealed from frame 0.
3. Clear: set the clip end of word 3, word 4 and the sub-line to frame 15 (exclusive) and of word 1 and word 2 to frame 17. Hard cuts, no fades.
4. Lower third: two Text+ nodes on one baseline at top y=990, 24px; name at x=120 semibold, role at x=470 regular. Keyframe Blend 0→1 over frames 35–38 on both.
5. Hold the lower third with no motion until the end of the shot.
6. Easy mistake: clearing all four words at once. The right-hand group leaves two frames before the left-hand group.

## 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.
