Description
create audio files, video clips into synced music video with this skill. Works with MP3, MP4, WAV, MOV files up to 500MB. musicians, music producers, content...
README (SKILL.md)

Getting Started

Share your audio files, video clips and I'll get started on AI music video creation. Or just tell me what you're thinking.

Try saying:

  • "create my audio files, video clips"
  • "export 1080p MP4"
  • "create a music video with beat-synced"

Getting Connected

Before handling any user request, establish a connection to the backend API. Show a brief status like "Connecting...".

If NEMO_TOKEN is in the environment, use it directly and create a session. Otherwise, acquire a free starter token:

  • Generate a UUID as client identifier
  • POST to https://mega-api-prod.nemovideo.ai/api/auth/anonymous-token with the X-Client-Id header
  • The response includes a token with 100 free credits valid for 7 days — use it as NEMO_TOKEN

Then create a session by POSTing to https://mega-api-prod.nemovideo.ai/api/tasks/me/with-session/nemo_agent with Bearer authorization and body {"task_name":"project","language":"en"}. The session_id in the response is needed for all following requests.

Tell the user you're ready. Keep the technical details out of the chat.

Music Video Clip — Create Beat-Synced Music Videos

Send me your audio files, video clips and describe the result you want. The AI music video creation runs on remote GPU nodes — nothing to install on your machine.

A quick example: upload a 3-minute MP3 song track, type "create a music video with beat-synced visuals and transitions for my new song", and you'll get a 1080p MP4 back in roughly 1-2 minutes. All rendering happens server-side.

Worth noting: shorter clips under 3 minutes process significantly faster and sync more accurately.

Matching Input to Actions

User prompts referencing music video clip, aspect ratio, text overlays, or audio tracks get routed to the corresponding action via keyword and intent classification.

User says... Action Skip SSE?
"export" / "导出" / "download" / "send me the video" → §3.5 Export
"credits" / "积分" / "balance" / "余额" → §3.3 Credits
"status" / "状态" / "show tracks" → §3.4 State
"upload" / "上传" / user sends file → §3.2 Upload
Everything else (generate, edit, add BGM…) → §3.1 SSE

Cloud Render Pipeline Details

Each export job queues on a cloud GPU node that composites video layers, applies platform-spec compression (H.264, up to 1080x1920), and returns a download URL within 30-90 seconds. The session token carries render job IDs, so closing the tab before completion orphans the job.

All calls go to https://mega-api-prod.nemovideo.ai. The main endpoints:

  1. SessionPOST /api/tasks/me/with-session/nemo_agent with {"task_name":"project","language":"\x3Clang>"}. Gives you a session_id.
  2. Chat (SSE)POST /run_sse with session_id and your message in new_message.parts[0].text. Set Accept: text/event-stream. Up to 15 min.
  3. UploadPOST /api/upload-video/nemo_agent/me/\x3Csid> — multipart file or JSON with URLs.
  4. CreditsGET /api/credits/balance/simple — returns available, frozen, total.
  5. StateGET /api/state/nemo_agent/me/\x3Csid>/latest — current draft and media info.
  6. ExportPOST /api/render/proxy/lambda with render ID and draft JSON. Poll GET /api/render/proxy/lambda/\x3Cid> every 30s for completed status and download URL.

Formats: mp4, mov, avi, webm, mkv, jpg, png, gif, webp, mp3, wav, m4a, aac.

Three attribution headers are required on every request and must match this file's frontmatter:

Header Value
X-Skill-Source music-video-clip
X-Skill-Version frontmatter version
X-Skill-Platform auto-detect: clawhub / cursor / unknown from install path

All requests must include: Authorization: Bearer \x3CNEMO_TOKEN>, X-Skill-Source, X-Skill-Version, X-Skill-Platform. Missing attribution headers will cause export to fail with 402.

Draft field mapping: t=tracks, tt=track type (0=video, 1=audio, 7=text), sg=segments, d=duration(ms), m=metadata.

Timeline (3 tracks): 1. Video: city timelapse (0-10s) 2. BGM: Lo-fi (0-10s, 35%) 3. Title: "Urban Dreams" (0-3s)

Backend Response Translation

The backend assumes a GUI exists. Translate these into API actions:

Backend says You do
"click [button]" / "点击" Execute via API
"open [panel]" / "打开" Query session state
"drag/drop" / "拖拽" Send edit via SSE
"preview in timeline" Show track summary
"Export button" / "导出" Execute export workflow

SSE Event Handling

Event Action
Text response Apply GUI translation (§4), present to user
Tool call/result Process internally, don't forward
heartbeat / empty data: Keep waiting. Every 2 min: "⏳ Still working..."
Stream closes Process final response

~30% of editing operations return no text in the SSE stream. When this happens: poll session state to verify the edit was applied, then summarize changes to the user.

Error Handling

Code Meaning Action
0 Success Continue
1001 Bad/expired token Re-auth via anonymous-token (tokens expire after 7 days)
1002 Session not found New session §3.0
2001 No credits Anonymous: show registration URL with ?bind=\x3Cid> (get \x3Cid> from create-session or state response when needed). Registered: "Top up credits in your account"
4001 Unsupported file Show supported formats
4002 File too large Suggest compress/trim
400 Missing X-Client-Id Generate Client-Id and retry (see §1)
402 Free plan export blocked Subscription tier issue, NOT credits. "Register or upgrade your plan to unlock export."
429 Rate limit (1 token/client/7 days) Retry in 30s once

Tips and Tricks

The backend processes faster when you're specific. Instead of "make it look better", try "create a music video with beat-synced visuals and transitions for my new song" — concrete instructions get better results.

Max file size is 500MB. Stick to MP3, MP4, WAV, MOV for the smoothest experience.

Export as MP4 with H.264 codec for the best balance of quality and file size across platforms.

Common Workflows

Quick edit: Upload → "create a music video with beat-synced visuals and transitions for my new song" → Download MP4. Takes 1-2 minutes for a 30-second clip.

Batch style: Upload multiple files in one session. Process them one by one with different instructions. Each gets its own render.

Iterative: Start with a rough cut, preview the result, then refine. The session keeps your timeline state so you can keep tweaking.

Usage Guidance
Before installing, make sure you are comfortable sending selected audio/video files to NemoVideo's cloud service and using a NemoVideo token or anonymous starter token. The artifacts do not show hidden code, local persistence, or unrelated system access.
Capability Analysis
Type: OpenClaw Skill Name: music-video-clip Version: 1.0.0 The music-video-clip skill (SKILL.md) connects to a third-party API at mega-api-prod.nemovideo.ai to generate synced music videos. It is classified as suspicious due to instructions that direct the agent to 'process internally' tool calls received from a remote Server-Sent Events (SSE) stream, which could allow a compromised backend to trigger unauthorized actions on the host. Furthermore, the skill requires the agent to auto-detect its platform from the installation path for telemetry and manages authentication via the NEMO_TOKEN environment variable, representing a significant attack surface despite being aligned with the stated functionality.
Capability Assessment
Purpose & Capability
The requested capabilities—uploading audio/video, creating sessions, rendering on cloud GPUs, and returning MP4 downloads—match the stated music-video creation purpose, but users should understand their media is processed by an external service.
Instruction Scope
The skill gives detailed API workflow instructions, including automatic session creation and export polling. These are purpose-aligned, but the agent may perform backend steps without showing all technical details in chat.
Install Mechanism
No install spec or code files are present; this is an instruction-only skill, and the static scanner had no code to analyze.
Credentials
The skill requires or obtains a NemoVideo token and sends requests to a single disclosed backend domain, which is proportionate for a cloud rendering service.
Persistence & Privilege
The skill uses remote sessions and tokens that last beyond a single API call, but the artifacts do not show local persistence, background execution, or privilege escalation.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install music-video-clip
  3. After installation, invoke the skill by name or use /music-video-clip
  4. Provide required inputs per the skill's parameter spec and get structured output
