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

What the source does

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.

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.

Phase notes

  1. Frame 0 — Short subtitle on a narrow plate
  2. Frame 26 — Hard swap to long line; plate widens to fit
  3. Frame 67 — Hard cut to close-up; subtitle cleared

Use this example

  1. Watch the source and draft at normal speed. Compare the order of actions, the held states, and the transition into the result.
  2. Download the project and read its README before changing inputs. The package includes its implementation and declared dependencies.
  3. Replace the sample content through the package's documented input or content builder. Keep source footage in the research comparison.
  4. Render your adaptation and inspect text fit, framing, intermediate states, and entry and exit frames.
A runnable draft is not a fidelity approval.

The source and remake are different assets. The original code-based illustration remains editable; source footage is a research reference. Read the retained findings below before using the choreography.

Recorded limits

  • Visual fidelity is an authored draft judgement from sampled source frames; no independent blind review or native Resolve execution.
