Online Video Editor Free

Turn raw clips into polished, share-ready videos without downloading a single app. This online-video-editor-free skill helps creators, marketers, and educato...

Security Scan

The skill's declared requirements and runtime instructions are coherent with an online cloud video editor: it needs a single service token (NEMO_TOKEN), will create a session with the remote API, and upload user-provided media for server-side processing.

Purpose & Capability

Name/description (online video editing) match the required credential (NEMO_TOKEN), API endpoints, and upload/session operations described in SKILL.md. No unrelated services or credentials are requested.

Instruction Scope

Runtime instructions are focused on obtaining/using a NEMO_TOKEN, creating a session, sending SSE messages, and uploading videos (multipart file uploads or URL-based uploads). These actions are expected for a cloud video editor. Potential scope concerns: the skill instructs reading environment variables and detecting install path, and it will read local file paths for uploads — those reads are expected when the user asks to upload files but could expose any local file path the agent is told to send. The SKILL.md also says not to expose tokens/raw API output.

Install Mechanism

Instruction-only skill with no install spec and no code files — lowest-risk install surface (nothing written to disk by an installer).

Credentials

The single required env var (NEMO_TOKEN) is proportional to a cloud service integration. Minor inconsistency: metadata declares configPaths (~/.config/nemovideo/) but the runtime instructions do not explicitly read or write that path; this may be benign (for user-saved settings) but is not justified in the instructions.

Persistence & Privilege

always:false and no instructions to modify other skills or system-wide settings. The skill keeps an in-session session_id for operations, which is normal for a session-based API.

Assessment

This skill appears to do what it claims: it will send media you provide to the nemo video API and needs a NEMO_TOKEN (it can request an anonymous token if none is set). Before installing or invoking: 1) Verify you trust the domain (mega-api-prod.nemovideo.ai) and review its privacy/retention policy — uploaded videos will be transmitted to that service. 2) Be cautious about asking the agent to upload arbitrary local paths — only provide files you intend to upload. 3) Note the skill may store/use a token for up to 7 days if it obtains an anonymous token; if you prefer, supply your own NEMO_TOKEN from a trusted account. 4) The metadata cites a config path (~/.config/nemovideo/) that the instructions don't explicitly use — if you are uncomfortable, check for any local files the skill creates or reads before use. If you want higher assurance, ask the publisher for documentation or a canonical homepage/source before proceeding.

Getting Started

Welcome to your free online video editing assistant — I'll help you cut, enhance, and export your videos without any software downloads. Tell me about your footage or the type of video you want to create, and let's get started!

Try saying:

• "Trim my video to 60 seconds"
• "Add captions to this clip"
• "Export video for Instagram Reels"

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.

Edit Any Video Free, Right From Your Browser

Not everyone has access to expensive desktop software like Premiere Pro or Final Cut — and they shouldn't need it. This skill is built around the idea that great video editing should be accessible to anyone with a browser and a story to tell. Whether you're a small business owner putting together a product walkthrough, a student editing a class project, or a content creator prepping short-form clips for TikTok or YouTube, this tool meets you where you are.

Using this online video editor free skill, you can get step-by-step guidance on trimming footage, layering text and captions, applying color corrections, adding background music, and structuring your timeline for maximum impact. You don't need to learn a complicated interface from scratch — just describe what you want your video to do, and you'll get clear, actionable instructions or direct editing support.

The focus here is practical output: videos that look intentional, not accidental. From aspect ratio adjustments for different platforms to export settings that won't bloat your file size, this skill covers the full editing workflow without the paywall.

Routing Edits to the Right Tool

When you describe a video task — trimming a clip, merging footage, adding captions, or exporting to MP4 — ClawHub parses your intent and routes it directly to the matching free online editor function without requiring any software download.

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 Processing API Reference

All video processing runs on a browser-based cloud rendering backend, meaning your trim points, cut sequences, and export settings are handled server-side — no local encoder needed. Supported formats include MP4, MOV, WebM, and GIF, with resolution options up to 1080p depending on your session tier.

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

• X-Skill-Source: online-video-editor-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 <NEMO_TOKEN>, X-Skill-Source, X-Skill-Version, X-Skill-Platform. Missing attribution headers will cause export to fail with 402.

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.

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 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)

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=<id> (get <id> 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
