revid-script-with-custom-media

Script + your own media → branded video

Calls the Revid MCP server (https://www.revid.ai/api/mcp). Install once — see revid-api-foundations.

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. Call MCP tool render_video with the payload below (note media.useOnlyProvided: true) — returns data.pid. Then poll MCP tool get_project_status with that pid every 5–8 s until data.status === "ready". Optionally call export_video for a freshly named mp4.

render_video arguments

{
  "workflow": "script-to-video",
  "source": {
    "text": "{SCRIPT}"
  },
  "aspectRatio": "9:16",
  "voice":    { "enabled": true, "voiceId": "aria-en-us", "stability": 0.6, "speed": 1.0 },
  "captions": { "enabled": true, "position": "middle", "autoCrop": true },
  "music":    { "enabled": true, "syncWith": "beats" },
  "media": {
    "type": "custom",
    "useOnlyProvided": true,
    "turnImagesIntoVideos": true,
    "mergeVideos": false,
    "animation": "soft",
    "provided": [
      { "url": "https://cdn.example.com/clip-1.mp4", "type": "video" },
      { "url": "https://cdn.example.com/clip-2.mp4", "type": "video" },
      { "url": "https://cdn.example.com/hero.jpg",   "type": "image" }
    ]
  },
  "options": {
    "summarizationPreference": "no-summarization",
    "useOnlyProvidedMedia": true,
    "soundEffects": false,
    "hasToGenerateCover": true
  },
  "render": { "resolution": "1080p", "frameRate": 30 }
}

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.

Polling

Call get_project_status with the pid returned by render_video. Stop when data.status === "ready"; fail when data.status === "failed". Cadence: 5 s, then 8 s once progress > 30. Full pseudocode: revid-api-foundations § Polling.

Examples

• examples/branded-script.json — copy-paste body for render_video (also a valid POST body for the direct HTTPS fallback).
• examples/run.sh — bash smoke test using the direct HTTPS fallback (POST /api/public/v3/render → GET /status). Useful when you don't have an MCP client at hand.

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).
ok: false, error: "insufficient_credits"	Drop media.quality to "standard" or render.resolution to "720p", or call buy_credit_pack.
