Video Compressor Ai

Turn bulky video files into lean, shareable assets without the quality loss that plagues traditional compression tools. video-compressor-ai analyzes your foo...

Security Scan

The skill's requirements and runtime instructions are consistent with a cloud-based video-compression service — it asks only for a single service token and describes uploading videos to a remote API, which matches its stated purpose.

Purpose & Capability

Name/description are about compressing video files; the only declared credential is NEMO_TOKEN for the remote nemovideo.ai API, which is appropriate for a cloud encoding/compression service.

Instruction Scope

SKILL.md instructs the agent to create sessions, upload files (multipart or URL), poll renders, and handle SSE—all expected for a remote transcoding service. It also instructs detecting an install path to set X-Skill-Platform (requires reading the agent's install path), and will upload user video files to an external endpoint; users should be aware that video content will be transmitted off-device.

Install Mechanism

No install spec and no code files — instruction-only skill which does not write code to disk. This is the lowest-risk install model.

Credentials

Only one environment variable (NEMO_TOKEN) is required and is directly used for API authorization; the instructions also include an option to obtain an anonymous token if NEMO_TOKEN is absent, which is consistent with the described behavior.

Persistence & Privilege

always is false and there is no claim to modify other skills or system-wide settings. The skill requires network access to a remote API but requests no special platform privileges.

Assessment

This skill sends your video files (and metadata needed for processing) to https://mega-api-prod.nemovideo.ai for cloud encoding. Before installing or using it: (1) do not upload sensitive or confidential footage unless you trust that service and have reviewed its privacy policy; (2) prefer using a disposable or limited-scope NEMO_TOKEN rather than a long-lived credential that grants broader access; (3) be aware the skill may read install-path information to set an attribution header (it leaks little system context but is still metadata about your environment); (4) confirm any costs or credit usage (the skill can obtain a 7-day anonymous token with limited credits); and (5) if you need local-only compression for privacy, choose a tool that runs entirely on-device. Overall this skill appears coherent for its stated purpose, but treat uploads and credentials with caution.

Getting Started

Welcome! I'm your Video Compressor AI — ready to help you reduce file sizes, optimize formats, and prep your videos for any platform or storage need. Tell me about your video and what you're trying to achieve, and let's compress it the smart way.

Try saying:

• "Compress this 2GB wedding video to under 500MB for sharing via email without making it look blurry"
• "Convert my MP4 file to H.265 format and reduce the file size by at least 60% while keeping 1080p resolution"
• "I have 200 training videos taking up 300GB — what compression settings should I use to cut storage in half without losing readability of on-screen text?"

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.

Compress Smarter: AI That Reads Your Footage

Most video compression tools treat every file the same — they apply a blanket setting and hope for the best. Video Compressor AI takes a different approach. By understanding the content of your video — motion complexity, scene transitions, color depth, and audio layers — it recommends and applies compression strategies tailored to what's actually in your footage.

Whether you're trimming a 4K drone reel down for Instagram, reducing a product demo for faster web loading, or archiving a library of training videos without blowing your storage budget, this skill adapts to your goal. You describe what you need in plain language — target file size, platform destination, acceptable quality trade-offs — and the AI handles the technical decisions behind the scenes.

No more guessing between H.264 and H.265, no more trial-and-error with CRF values, and no more re-exporting the same clip five times. Video Compressor AI brings precision compression into a workflow that actually fits how creators and teams operate day-to-day.

Compression Request Routing Logic

When you submit a video, your request is parsed for codec preference, target bitrate, resolution constraints, and container format before being dispatched to the optimal processing node.

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 Encoding Backend Reference

Video Compressor AI routes encoded workloads through a distributed transcoding cluster that applies perceptual quality metrics — including VMAF and SSIM scoring — to preserve visual fidelity while aggressively reducing file size. Each job runs in an isolated encoding pipeline supporting H.264, H.265/HEVC, AV1, and VP9 output targets.

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

• X-Skill-Source: video-compressor-ai
• 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.

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 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

Best Practices

Always start with your original, uncompressed source file. Compressing an already-compressed video compounds quality loss in ways that even the best AI settings cannot fully recover from. If you've lost the original, mention this upfront so the AI can adjust its approach to minimize generational degradation.

Be specific about your destination. A video compressed for a 4K TV screen needs a very different profile than one destined for a mobile app thumbnail preview. The more context you give — device type, viewing environment, bandwidth constraints — the more accurate the compression recommendation will be.

For long-form content like webinars or documentaries, consider asking the AI about scene-based compression, where static talking-head segments get higher compression rates than fast-action sequences. This hybrid approach can yield 30–50% better file size reduction compared to flat compression across the whole file.

Finally, always request a quality checkpoint before finalizing batch jobs. Ask the AI to flag which settings carry the highest risk of visible degradation so you can review those files manually before delivery.

Quick Start Guide

Getting started with Video Compressor AI is straightforward — no encoding knowledge required. Begin by describing your video: its current format, resolution, duration, and file size if known. Then tell the AI your end goal — whether that's hitting a specific file size, meeting a platform's upload limit (like YouTube, TikTok, or LinkedIn), or simply reducing storage footprint.

The AI will ask clarifying questions if needed — for example, whether audio quality matters as much as video, or whether you need the output in a specific container format like MP4, MOV, or WebM. Once it has enough context, it will generate a recommended compression profile with clear reasoning behind each setting.

For batch compression needs, describe your folder structure or file naming convention and the AI will suggest a consistent compression strategy you can apply across all files. You can also request a comparison — asking the AI to outline what you'd gain and lose at different compression levels before committing to a final export setting.

Use Cases

Video Compressor AI serves a wide range of real-world scenarios across industries and workflows. Social media managers use it to hit platform-specific file size caps — TikTok's 287MB limit or Instagram's 650MB ceiling — without re-shooting or over-cropping content. The AI knows the sweet spots for each platform and compresses accordingly.

E-learning developers rely on it to shrink course video libraries before uploading to LMS platforms like Teachable or Moodle, where storage costs scale with file size. By compressing lecture recordings intelligently, text and slides remain crisp while overall file size drops dramatically.

Filmmakers and video editors use it during client delivery — sending proxy-quality previews for approval before handing over full-resolution masters. And for businesses running video-heavy websites, the AI helps optimize autoplay background videos and product demos to reduce page load times without introducing compression artifacts that would undermine brand perception.
