generate text or script into voiced video files with this skill. Works with MP4, MOV, TXT, DOCX files up to 200MB. content creators, marketers, students use...

使用说明 (SKILL.md)

Getting Started

Share your text or script and I'll get started on AI voiceover generation. Or just tell me what you're thinking.

Try saying:

"generate my text or script"
"export 1080p MP4"
"generate a natural voiceover for my"

Automatic Setup

On first interaction, connect to the processing API before doing anything else. Show a brief status like "Setting things up...".

Token: If NEMO_TOKEN environment variable is already set, use it and skip to Session below.

Free token: Generate a UUID as client identifier, then POST to https://mega-api-prod.nemovideo.ai/api/auth/anonymous-token with header X-Client-Id: \x3Cuuid>. The response field data.token becomes your NEMO_TOKEN (100 credits, 7-day expiry).

Session: POST to https://mega-api-prod.nemovideo.ai/api/tasks/me/with-session/nemo_agent with Bearer auth and body {"task_name":"project"}. Save session_id from the response.

Confirm to the user you're connected and ready. Don't print tokens or raw JSON.

AI Voiceover Generator Free — Generate Voiceovers for Videos

Name: Ai Voiceover Generator Free
Author: francemichaell-15

Send me your text or script and describe the result you want. The AI voiceover generation runs on remote GPU nodes — nothing to install on your machine.

A quick example: upload a 200-word product description script, type "generate a natural voiceover for my script in a female American English voice", and you'll get a 1080p MP4 back in roughly 20-40 seconds. All rendering happens server-side.

Worth noting: shorter scripts under 150 words produce the most natural-sounding results.

Matching Input to Actions

User prompts referencing ai voiceover generator free, 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.

Base URL: https://mega-api-prod.nemovideo.ai

Endpoint	Method	Purpose
`/api/tasks/me/with-session/nemo_agent`	POST	Start a new editing session. Body: `{"task_name":"project","language":"\x3Clang>"}`. Returns `session_id`.
`/run_sse`	POST	Send a user message. Body includes `app_name`, `session_id`, `new_message`. Stream response with `Accept: text/event-stream`. Timeout: 15 min.
`/api/upload-video/nemo_agent/me/\x3Csid>`	POST	Upload a file (multipart) or URL.
`/api/credits/balance/simple`	GET	Check remaining credits (`available`, `frozen`, `total`).
`/api/state/nemo_agent/me/\x3Csid>/latest`	GET	Fetch current timeline state (`draft`, `video_infos`, `generated_media`).
`/api/render/proxy/lambda`	POST	Start export. Body: `{"id":"render_\x3Cts>","sessionId":"\x3Csid>","draft":\x3Cjson>,"output":{"format":"mp4","quality":"high"}}`. Poll status every 30s.

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

Skill attribution — read from this file's YAML frontmatter at runtime:

X-Skill-Source: ai-voiceover-generator-free
X-Skill-Version: from frontmatter version
X-Skill-Platform: detect from install path (~/.clawhub/ → clawhub, ~/.cursor/skills/ → cursor, else unknown)

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.

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

Reading the SSE Stream

Text events go straight to the user (after GUI translation). Tool calls stay internal. Heartbeats and empty data: lines mean the backend is still working — show "⏳ Still working..." every 2 minutes.

About 30% of edit operations close the stream without any text. When that happens, poll /api/state to confirm the timeline changed, then tell the user what was updated.

Translating GUI Instructions

The backend responds as if there's a visual interface. Map its instructions to API calls:

"click" or "点击" → execute the action via the relevant endpoint
"open" or "打开" → query session state to get the data
"drag/drop" or "拖拽" → send the edit command through SSE
"preview in timeline" → show a text summary of current tracks
"Export" or "导出" → run the export workflow

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)

Common Workflows

Quick edit: Upload → "generate a natural voiceover for my script in a female American English voice" → Download MP4. Takes 20-40 seconds 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.

Tips and Tricks

The backend processes faster when you're specific. Instead of "make it look better", try "generate a natural voiceover for my script in a female American English voice" — concrete instructions get better results.

Max file size is 200MB. Stick to MP4, MOV, TXT, DOCX for the smoothest experience.

Export as MP4 for widest compatibility across platforms and devices.

安全使用建议

This skill appears to perform the advertised cloud voiceover rendering by calling mega-api-prod.nemovideo.ai, which requires either a NEMO_TOKEN or an anonymous token the skill can mint for you. Before installing or enabling it, consider: (1) The registry claims NEMO_TOKEN is required, but the runtime docs describe an anonymous-token fallback — ask the author to fix this contradiction. (2) The SKILL.md asks the agent to detect install paths and references a local config path (~/.config/nemovideo/); ask why it needs to read local install/config locations and demand that any local reads be minimal and documented. (3) Files you upload (videos, docs) will be sent to a remote service; verify the service domain and privacy/data retention policy and avoid uploading sensitive content. (4) Prefer using ephemeral/limited tokens rather than long-lived credentials; if you must provide NEMO_TOKEN, create a scoped/test account first. If the developer cannot justify the config/metadata mismatches and filesystem reads, treat the skill as untrusted and do not enable it.

功能分析

Type: OpenClaw Skill Name: ai-voiceover-generator-free Version: 1.0.0 The skill is a functional integration for the NemoVideo AI voiceover service, providing a structured way for the agent to interact with the mega-api-prod.nemovideo.ai backend. It includes clear instructions for authentication (including a fallback for anonymous tokens), session management, file uploads, and rendering workflows. The instructions are well-aligned with the stated purpose and include security-conscious directives, such as preventing the agent from displaying raw tokens or sensitive JSON responses to the user.

能力评估

ℹ Purpose & Capability

The name and description (AI voiceover rendering) align with the SKILL.md's use of a remote NEMO API (upload files, start render jobs). However, the registry lists NEMO_TOKEN as a required env var while the SKILL.md describes an anonymous-token flow if NEMO_TOKEN is not present — so the declared requirement is inconsistent with the runtime instructions. Also the SKILL.md frontmatter includes a configPaths entry (~/.config/nemovideo/) that the registry metadata did not list, which is another mismatch.

⚠ Instruction Scope

The instructions direct uploads of user files (expected) and multiple API calls to mega-api-prod.nemovideo.ai (expected for a cloud render service). But they also require the agent to derive X-Skill-Platform by inspecting install paths (~/.clawhub/, ~/.cursor/skills/), which implies reading local filesystem/installation context unrelated to generating a voiceover. Reading local skill install paths or user config is not required for content rendering and widens the skill's scope.

✓ Install Mechanism

There is no install spec and no code files; the skill is instruction-only so nothing is written to disk by an installer. This is the lowest-risk install mechanism.

⚠ Credentials

The only declared credential is NEMO_TOKEN (appropriate for a third-party API). However, SKILL.md provides an anonymous-token fallback and therefore NEMO_TOKEN should not be a hard required variable — the registry claiming it as required is inconsistent. The frontmatter's configPaths entry (~/.config/nemovideo/) would grant access to a local configuration directory (if actually read) which is disproportionate unless used only to find cached API tokens — that behavior is not clearly justified.

ℹ Persistence & Privilege

The skill does not request always:true and does not request elevated platform privileges. Still, the instruction to detect install path and read YAML frontmatter to set attribution headers implies the skill may inspect local installation context; while not highly privileged, this is broader than strictly needed for rendering and should be clarified.
