Overlays silent b-roll cutaway clips onto a finished base video — the base audio keeps running underneath while the picture cuts away and returns, and the final duration always equals the base duration. Use when the user asks to add b-roll, add cutaways, or overlay clips on a video: "add b-roll to this", "cut away to a product shot here", "overlay these clips on my UGC ad". Entered from an approved base video plus its transcript, which comes from POST /v1/transcripts and needs no local…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# B-roll overlay

Lays silent cutaway clips **over** a finished base video: the base audio runs
untouched underneath, the picture cuts away and returns, and the final duration
equals the base duration exactly. That is the whole contract — overlay, never
concatenation. A previous run concatenated: 24s for a 15s base, voice dead 12s.

Assembly mechanics live entirely in `scripts/broll_overlay.py`; this file is
judgment only — when to enter, where the windows go, what the user sees first.

## Entry condition

Two things must already exist. This skill never generates the base — if there
isn't one yet, say so and stop.

1. **A finished, approved base video with exactly one audio stream.** Approved
   means the user has watched it and signed off — b-roll is a polish pass over a
   locked cut. The script stream-copies one voice track under the picture, so a
   two-stream base is rejected: `ffmpeg -i base -map 0:v -map 0:a:0 -c copy`.
2. **Its transcript, with timings.** One call to **`POST /v1/transcripts`** with
   the base's `jobId` (or its `assetId` if it was uploaded). It returns `text`,
   word-level `words[]` and `segments[]` — **timings in SECONDS**, which is what
…

How to install

The exact contents, by fingerprint
mdr add novoads/agent-skills/broll-overlay@sha256:3917eb1e4bc652cd

The line at the top of this page pins the label git:20260911.9e39357, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
