Vertical Short-Form Video Editor

Reframe horizontal 16:9 footage into 9:16 vertical short-form videos with subject tracking and captions.

Reframe horizontal 16:9 footage into 9:16 vertical short-form videos with subject tracking and captions.

Setup

This skill calls the Levea (livecore.ai) editing service, which requires a Levea account and API key.

1. Sign up and generate an API key at https://livecore.ai/?openclaw=1&utm_source=clawhub&utm_medium=skill&utm_campaign=tiktok-reels-shorts-editor
2. Provide the key to the tool you use:
   • OpenClaw plugin openclaw-ai-video-editor (ClawHub): set apiKey in the plugin config.
   • MCP server levea-mcp-server (npm): set LEVEA_API_KEY in the MCP server config. LEVEA_API_URL is optional and defaults to https://api.livecore.ai.
3. Describe the edit you want in plain language; the tool returns a project ID and, after export, an MP4 URL.

When to use

• Converting 16:9 landscape footage into a 9:16 vertical aspect ratio.
• Keeping the active speaker centered within the vertical frame across camera cuts.
• Trimming a long clip into a 15-to-60 second vertical short with captions.

Tool interface

Use the registered ai-video-editor (OpenClaw plugin) or autonomous_edit (MCP server) tool to run edits against a project timeline.

Tool parameters

• prompt (string, required): Description of the video edit to perform, in the user's own words.
• project_id (string, optional): Project identifier returned by a prior call; reuse it for every follow-up edit on the same video.
• video_url (string, optional): Public source video URL when starting a new project.
• assets (array, optional): Input media (video, image, audio) as public HTTP/HTTPS URLs.
• scene (object, optional): Existing scene/timeline state to continue editing (advanced).
• captionTemplatePreset (string, optional): Caption template id to apply: a builtin slug (e.g. hormozi, viral-pop, karaoke) or a saved template id. With the MCP server, list_caption_templates lists the exact ids; elsewhere, name the look in the prompt.
• captionTemplateMode (string, optional): How to apply captionTemplatePreset: one of add, recreate, style, translate, clear, remove_fillers.
• requirePlanApproval (boolean, optional): When true, pause after planning and return workingMemory for the user to approve.
• workingMemory (object, optional): State returned by a paused plan-approval call; send it back to resume.
• editedPlan (object, optional): The user's edited version of a plan returned by an approval pause.
• planDecision (string, optional): Set to "approve" to approve the plan from an approval pause; resend it with that response's workingMemory.
• attachedImages (array, optional): Reference image URLs for planning (style, branding).
• flaggedIssues (array, optional): Specific problems the user flagged that this run must fix.
• brandId (string, optional): Brand kit to apply to this call.
• projectBrandId (string, optional): Default brand kit for the project; persists across calls.
• core_only (boolean, optional): Return only rendering-essential scene fields (smaller responses).
