Description
Turn a 10-minute DaVinci Resolve project export into 1080p captioned videos just by typing what you need. Whether it's adding auto-generated subtitles to DaV...
README (SKILL.md)

Getting Started

Send me your video clips and I'll handle the subtitle generation. Or just describe what you're after.

Try saying:

  • "generate a 10-minute DaVinci Resolve project export into a 1080p MP4"
  • "generate subtitles for my DaVinci Resolve video and sync them automatically"
  • "adding auto-generated subtitles to DaVinci Resolve videos for video editors"

Quick Start Setup

This skill connects to a cloud processing backend. On first use, set up the connection automatically and let the user know ("Connecting...").

Token check: Look for NEMO_TOKEN in the environment. If found, skip to session creation. Otherwise:

  • Generate a UUID as client identifier
  • POST https://mega-api-prod.nemovideo.ai/api/auth/anonymous-token with X-Client-Id header
  • Extract data.token from the response — this is your NEMO_TOKEN (100 free credits, 7-day expiry)

Session: POST https://mega-api-prod.nemovideo.ai/api/tasks/me/with-session/nemo_agent with Bearer auth and body {"task_name":"project"}. Keep the returned session_id for all operations.

Let the user know with a brief "Ready!" when setup is complete. Don't expose tokens or raw API output.

Subtitle Generator for DaVinci — Generate Subtitles for DaVinci Videos

This tool takes your video clips and runs subtitle generation through a cloud rendering pipeline. You upload, describe what you want, and download the result.

Say you have a 10-minute DaVinci Resolve project export and want to generate subtitles for my DaVinci Resolve video and sync them automatically — the backend processes it in about 30-60 seconds and hands you a 1080p MP4.

Tip: export your DaVinci Resolve timeline as MP4 first before uploading for best subtitle sync accuracy.

Matching Input to Actions

User prompts referencing subtitle generator davinci, 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: subtitle-generator-davinci
  • X-Skill-Version: from frontmatter version
  • X-Skill-Platform: detect from install path (~/.clawhub/clawhub, ~/.cursor/skills/cursor, else unknown)

Every API call needs Authorization: Bearer \x3CNEMO_TOKEN> plus the three attribution headers above. If any header is missing, exports return 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.

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

Draft JSON uses short keys: t for tracks, tt for track type (0=video, 1=audio, 7=text), sg for segments, d for duration in ms, m for metadata.

Example timeline summary:

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

Tips and Tricks

The backend processes faster when you're specific. Instead of "make it look better", try "generate subtitles for my DaVinci Resolve video and sync them automatically" — concrete instructions get better results.

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

Export from DaVinci Resolve as H.264 MP4 for fastest processing and widest compatibility.

Common Workflows

Quick edit: Upload → "generate subtitles for my DaVinci Resolve video and sync them automatically" → Download MP4. Takes 30-60 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.

Usage Guidance
This appears safe for its stated purpose, but it is not an offline subtitle tool. Before installing or invoking it, be comfortable with sending your video/audio/image files and edit instructions to the NemoVideo cloud service, and keep the NEMO_TOKEN private.
Capability Analysis
Type: OpenClaw Skill Name: subtitle-generator-davinci Version: 1.0.0 The subtitle-generator-davinci skill is a legitimate integration for a cloud-based video processing service. It provides instructions for the agent to manage authentication, upload video files, and poll for rendering status via the domain mega-api-prod.nemovideo.ai. The skill's behavior, including the handling of the NEMO_TOKEN and session management, is consistent with its stated purpose of generating subtitles for DaVinci Resolve exports, and it contains explicit instructions to the agent to avoid exposing sensitive tokens or raw API data.
Capability Assessment
Purpose & Capability
The stated purpose is to generate subtitles/render videos through a cloud pipeline, which matches the documented API calls and media upload flow.
Instruction Scope
The skill tells the agent to automatically create a service token/session on first use and route edit/generation requests to the backend; this is disclosed and purpose-aligned.
Install Mechanism
No install spec, binaries, or code files are present, so the provided artifacts do not show local code execution or package-install risk.
Credentials
The NEMO_TOKEN credential and external API access are expected for the cloud rendering service, but media uploads may include private user content.
Persistence & Privilege
The skill uses a session_id and a 7-day token for render jobs; the artifacts do not show hidden background persistence beyond cloud job/session handling.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install subtitle-generator-davinci
  3. After installation, invoke the skill by name or use /subtitle-generator-davinci
  4. Provide required inputs per the skill's parameter spec and get structured output
