video-assembly SKILL.md skillA
video-assembly from ybz21/roami is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add ybz21/roami/video-assembly@git:20261031.504c2ecPins git:20261031.504c2ec in mdr.lock. Pin the fingerprint instead.

Concatenate chosen complete MP4 clips into one video and a matching segment manifest, normalizing mixed frame and audio rates. Use after clip selection; it does not identify scenes or choose storyboard matches.
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
Use available visual evidence or suitable analysis to select clips. Filenames and media metadata alone do not establish scene meaning. Keep uncertainty explicit when the available capabilities cannot confirm a match.
For full-clip concatenation, `scripts/assemble.py` handles frame-rate conversion, canvas padding, missing/short audio, one continuous encode, output frame/duration checks, and a timeline manifest. It uses Python's standard library plus installed `ffmpeg` and `ffprobe`; it does not install dependencies or call a model.
Create a workspace JSON spec:
```json
{"inputs":[{"path":"clips/intro.mp4"},{"path":"clips/ending.mp4"}],"video":"output/sequence.mp4","manifest":"output/sequence.json"}
```
Run `python /path/from/skill-read/scripts/assemble.py --workspace /your/workspace --spec assembly.json`. Use the actual materialized skill path returned by `read`, and the task's bound workspace. Read back the receipt and final files before reporting delivery.

How to install
mdr add ybz21/roami/video-assembly@sha256:fc38ff199d9c6b8aThe line at the top of this page pins the label git:20261031.504c2ec, 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.
