What changes across the edit

Shot boundary: The source builds its wordmark, deletes letters, introduces the knot and reaches a quiet endpoint; this is not a dissolve template.
Framing: Small centered identity on a white field with ample margins.
Layer ownership: Wordmark, changing knot geometry and background. Exact original layer construction is unknown.
Motion: Letter changes and a brief mark turn precede the mostly stable last samples.
Typography: Source wordmark behavior is studied, not licensed or reproduced.
Action order: Wordmark build → hold → deletion → mark change → quiet ending.
Pacing & readable holds: The mark appears stable across 130.881, 131.298, 131.757, 132.174 and 132.591 s samples. These samples do not prove every intervening pixel is frozen.

Recreation versus observation

Matches

Short original identity construction followed by a guaranteed motionless tail.

Differs

Three simple original bars, not the source wordmark or knot. Letter deletion and knot rotation are not recreated; the supported recipe is quiet-ending structure only.

Measured

Exact inspected excerpt 127.85–132.61 s; consecutive subset 128.0–128.8 s covers the early wordmark, not the final hold.

Inferred

Quiet final samples suggest an attention release, not a prescribed OBS buffer.

Chosen defaults

All Remotion phase frames, cubic Bézier (.16,1,.3,1), geometry, colors, font choice and reading holds are chosen defaults. None is a recovered OpenAI specification.

Increase hold to extend only the final quiet state. Change the phase frames to change choreography; preserve their ordering. Content limits and the exact meaning of each phase are in the handoff.
