Script + Custom Media

---

name: revid-script-with-custom-media description: Render a video from a script using only the media assets the caller provides (no stock visuals). Use for branded content where every frame must be on-brand — product clips, brand b-roll, hand-shot footage. metadata: {"openclaw":{"requires":{"config":["REVID_API_KEY"]}}}

Script + your own media → branded video

For when the user has the script *and* the visuals. Revid only handles voice + captions + assembly. No stock content is mixed in.

When to use this skill

The user has both a script and a set of clips/images they want used.

Brand fidelity matters more than visual variety.

For mixed (your media + stock to fill gaps), drop media.useOnlyProvided and

use revid-script-to-video with media.provided.

Inputs

| Field | Required | Notes | |---|---|---| | text | yes | The script | | media.provided[] | yes | At least 3 items recommended; URLs must be public | | aspectRatio | no | Default 9:16 | | voiceId | no | Default voice if omitted |

MediaItem shape:

{ "url": "https://…", "type": "image" | "video" | "audio", "title": "optional", "noReencode": false }

Use type: "image" for stills (Revid will optionally pan/zoom them via media.turnImagesIntoVideos). Use type: "video" for clips. Keep clip duration roughly comparable to the script length.

Step-by-step

1. Validate every media.provided[].url returns 200 and a video/image content-type. 2. Confirm enough assets for the script: rough rule = 1 asset per 8–10 s of script, minimum 3. 3. POST /render with media.useOnlyProvided: true. 4. Poll /status.

Both media.useOnlyProvided and options.useOnlyProvidedMedia should be true — they belong to slightly different paths in the legacy code and setting both is the safest way to forbid stock fill.

Failure modes

| Symptom | Fix | |---|---| | Final video pads with stock anyway | One of the two flags wasn't honored. Make sure both media.useOnlyProvided: true AND options.useOnlyProvidedMedia: true are set. | | Video too short / dead air | Not enough assets. Add more provided items or set mergeVideos: true to loop the existing clips. | | Wrong asset on a particular line | Pre-order assets in the array roughly in narrative order — Revid uses array order as a hint. | | Asset URL 403 / 404 | Make sure assets are public (signed URLs work as long as they don't expire mid-render). |
