video-replicate

Video replicate tool: extracts the first frame and audio from the source video, runs video understanding for a prompt, and returns a Seedance 2.0 replicate bundle (first frame + audio + video).

Overview

Field	Value
Model ID	`video-replicate`
CLI	`dlazy video-replicate`
MCP	`video-replicate` (Claude Code surfaces this as `mcp__dlazy__video-replicate`)
Type	`video`
Execution	Async task; the CLI polls until completion (`--no-wait` returns `generateId` immediately)
Batch	Supports `--batch <n>` parallel fan-out

Parameters

Arg	Type	Required	Notes
`videos`	array<url>	Yes	Videos; video (accepts URL, local path, or data: URL)
`durationSeconds`	string	No	Duration (s)

--input @file.json or --input '{...}' can supply all args at once; flags take precedence over --input keys.

CLI Examples

dlazy video-replicate --videos "https://example.com/source1.mp4" "https://example.com/source2.mp4" --batch 4

Compose with a pipeline

dlazy seedance-2.0-fast --prompt "reference clip" \
  | dlazy video-replicate --videos -

MCP is consumed by AI clients, not handwritten. Once dLazy is registered as an MCP server the tool appears in the client's tool list — Claude Code surfaces it as mcp__dlazy__video-replicate; generic clients (e.g. OpenClaw) call it as video-replicate.

See MCP setup for how to add the server.

Output

{
  "outputs": [
    { "type": "video", "id": "o_...", "url": "https://files.dlazy.com/result.mp4", "mimeType": "video/mp4" }
  ]
}

Media tools emit image / video / audio / file outputs. Use --output url to print only the URLs on stdout.
