Video Editor Free Windows

edit raw video clips into edited MP4 clips with this skill. Works with MP4, MOV, AVI, WebM files up to 500MB. Windows PC users and casual creators use it for...

Security Scan

The skill mostly does what it says (server-side video editing) and requests a single service token, but there are a few mismatches and automatic network behaviors you should understand before installing.

Purpose & Capability

The skill claims cloud-based video editing and only requires a single service token (NEMO_TOKEN), which is coherent with a remote-rendering service. Minor mismatch: the SKILL.md frontmatter mentions a config path (~/.config/nemovideo/) while the registry metadata lists no required config paths — this inconsistency should be clarified but does not by itself indicate malicious intent.

Instruction Scope

Runtime instructions direct the agent to contact a remote API (mega-api-prod.nemovideo.ai) to obtain an anonymous token if NEMO_TOKEN is not set, create sessions, upload user files, stream SSE for edits, and poll render status. These network actions are expected for a cloud editor, but the skill also instructs the agent to automatically 'connect to the processing backend' on first open and to hide raw API responses and token values — automatic backend connection and silent token handling could be surprising to users and should be made explicit before uploading private videos.

Install Mechanism

No install spec and no code files are present (instruction-only). That is lower risk because nothing is written to disk by an installer, but the skill does require outbound network requests at runtime.

Credentials

Only one environment credential (NEMO_TOKEN) is declared as required and is the primary credential. The SKILL.md documents an anonymous-token flow to generate a NEMO_TOKEN if absent; this is functionally consistent but inconsistent from a UX/authorization perspective (declared required env var vs. auto-generation). No other unrelated secrets are requested.

Persistence & Privilege

The skill does not request always:true, does not modify other skills, and only directs storing a session_id and token for its own requests. That is normal for a service-backed skill; persistent presence is not requested.

What to consider before installing

This skill will upload your videos to the remote service at https://mega-api-prod.nemovideo.ai and may automatically obtain a temporary anonymous token if you haven't provided NEMO_TOKEN. Before installing, confirm you are comfortable with your videos leaving your machine and check the service's privacy/terms (who can access stored videos, retention, and deletion). Ask the publisher to clarify the config-path mention in the frontmatter (~/.config/nemovideo/) and whether the skill will auto-connect on first open — if you prefer explicit consent, require the skill to prompt before creating a token or uploading files. If you cannot verify the backend or privacy terms, avoid using the skill for sensitive or private footage.

Getting Started

Share your raw video clips and I'll get started on AI video editing. Or just tell me what you're thinking.

Try saying:

• "edit my raw video clips"
• "export 1080p MP4"
• "trim the footage, add transitions, and"

First-Time Connection

When a user first opens this skill, connect to the processing backend automatically. Briefly let them know (e.g. "Setting up...").

Authentication: Check if NEMO_TOKEN is set in the environment. If it is, skip to step 2.

1. Obtain a free token: Generate a random UUID as client identifier. POST to https://mega-api-prod.nemovideo.ai/api/auth/anonymous-token with header X-Client-Id set to that UUID. The response data.token is your NEMO_TOKEN — 100 free credits, valid 7 days.
2. Create a session: POST to https://mega-api-prod.nemovideo.ai/api/tasks/me/with-session/nemo_agent with Authorization: Bearer <token>, Content-Type: application/json, and body {"task_name":"project","language":"<detected>"}. Store the returned session_id for all subsequent requests.

Keep setup communication brief. Don't display raw API responses or token values to the user.

Video Editor Free Windows — Edit and Export Videos Free

Send me your raw video clips and describe the result you want. The AI video editing runs on remote GPU nodes — nothing to install on your machine.

A quick example: upload a 3-minute screen recording or phone footage, type "trim the footage, add transitions, and export as a clean MP4", and you'll get a 1080p MP4 back in roughly 1-2 minutes. All rendering happens server-side.

Worth noting: shorter clips under 2 minutes process significantly faster.

Matching Input to Actions

User prompts referencing video editor free windows, 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.

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

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

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.

API base: https://mega-api-prod.nemovideo.ai

Create session: POST /api/tasks/me/with-session/nemo_agent — body {"task_name":"project","language":"<lang>"} — returns task_id, session_id.

Send message (SSE): POST /run_sse — body {"app_name":"nemo_agent","user_id":"me","session_id":"<sid>","new_message":{"parts":[{"text":"<msg>"}]}} with Accept: text/event-stream. Max timeout: 15 minutes.

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 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)

Error Codes

• 0 — success, continue normally
• 1001 — token expired or invalid; re-acquire via /api/auth/anonymous-token
• 1002 — session not found; create a new one
• 2001 — out of credits; anonymous users get a registration link with ?bind=<id>, registered users top up
• 4001 — unsupported file type; show accepted formats
• 4002 — file too large; suggest compressing or trimming
• 400 — missing X-Client-Id; generate one and retry
• 402 — free plan export blocked; not a credit issue, subscription tier
• 429 — rate limited; wait 30s and retry once

Tips and Tricks

The backend processes faster when you're specific. Instead of "make it look better", try "trim the footage, add transitions, and export as a clean MP4" — concrete instructions get better results.

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

Export as MP4 for widest compatibility across Windows media players and platforms.

Common Workflows

Quick edit: Upload → "trim the footage, add transitions, and export as a clean MP4" → 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.
