jimeng-i2v-first

Jimeng first-frame-to-video model, uses first frame + text to generate video. Suitable for single-shot scenes that naturally animate static images.

Overview

Field	Value
Model ID	`jimeng-i2v-first-v30`
CLI	`dlazy jimeng-i2v-first`
MCP	`jimeng-i2v-first` (Claude Code surfaces this as `mcp__dlazy__jimeng-i2v-first`)
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
`prompt`	string	Yes	Prompt
`firstFrame`	url	No	First Frame; image (accepts URL, local path, or data: URL)
`duration`	"5" \| "10"	No	Duration (s); default `"5"`

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

CLI Examples

dlazy jimeng-i2v-first --help
dlazy jimeng-i2v-first --prompt "Write your prompt here" --firstFrame "https://example.com/reference.jpg"
dlazy jimeng-i2v-first --prompt "Write your prompt here" --firstFrame "./local-image.png"
dlazy jimeng-i2v-first --prompt "Write your prompt here" --firstFrame "https://example.com/reference.jpg" --dry-run
dlazy jimeng-i2v-first --prompt "Write your prompt here" --firstFrame "https://example.com/reference.jpg" --no-wait
dlazy jimeng-i2v-first --prompt "Write your prompt here" --firstFrame "https://example.com/reference.jpg" --batch 4

Compose with a pipeline

dlazy gpt-image-2 --prompt "reference visual" \
  | dlazy jimeng-i2v-first --firstFrame - --prompt "Write your prompt here"

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__jimeng-i2v-first; generic clients (e.g. OpenClaw) call it as jimeng-i2v-first.

See MCP setup for how to add the server.

  "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.
