## Getting Started

> Welcome! If you're hunting for the best free AI tools for video editing, you're in the right place — tell me about your project, platform, or editing challenge and I'll point you to the right tools instantly.

**Try saying:**
- "I make YouTube Shorts and need a free AI tool that can auto-caption and trim dead air from my recordings — what do you recommend?"
- "What are the best free AI video editors for beginners that don't add watermarks to exported videos?"
- "I need a free AI tool that can remove backgrounds from video footage without a green screen — which ones actually work well?"

### 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: <uuid>`. 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.

# Discover Free AI Video Editors That Actually Work

Finding a genuinely free AI video editing tool feels harder than it should be. Most lists are padded with freemium traps, expired trials, or tools that slap a watermark on everything you export. This skill is built to cut through exactly that — surfacing tools that offer real, usable AI features at zero cost.

Whether you need automatic subtitle generation, AI-powered background removal, smart cut detection, or one-click highlight reels, there's a free tool out there that fits your specific workflow. The challenge is knowing which one matches your platform, skill level, and output goals. That's where this skill helps — it asks the right questions and delivers targeted recommendations instead of a generic ranked list.

Creators working on YouTube Shorts, TikTok, indie documentaries, or corporate explainer videos all have different needs. This skill accounts for those differences, helping you spend less time researching and more time editing. From browser-based tools you can use right now to downloadable apps with serious AI horsepower, you'll walk away knowing exactly where to start.

## Routing Your Editor Requests

When you query for free AI video editing tools, ClawHub parses your intent — whether you're hunting for auto-captioning, background removal, scene detection, or timeline automation — and routes your request to the most relevant tool comparison engine.

| 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

ClawHub's backend leverages a cloud processing layer that indexes and benchmarks free AI video editors in real time, pulling render performance metrics, export format support, and watermark restrictions so comparisons stay accurate. Each API call fetches live capability data from supported tools like CapCut, DaVinci Resolve, Runway ML free tier, and Clipchamp without caching stale feature sets.

Skill attribution — read from this file's YAML frontmatter at runtime:
- `X-Skill-Source`: `best-ai-tools-for-video-editing-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.

**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.

**Upload**: POST `/api/upload-video/nemo_agent/me/<sid>` — file: multipart `-F "files=@/path"`, or URL: `{"urls":["<url>"],"source_type":"url"}`

**Credits**: GET `/api/credits/balance/simple` — returns `available`, `frozen`, `total`

**Session state**: GET `/api/state/nemo_agent/me/<sid>/latest` — key fields: `data.state.draft`, `data.state.video_infos`, `data.state.generated_media`

**Export** (free, no credits): POST `/api/render/proxy/lambda` — body `{"id":"render_<ts>","sessionId":"<sid>","draft":<json>,"output":{"format":"mp4","quality":"high"}}`. Poll GET `/api/render/proxy/lambda/<id>` every 30s until `status` = `completed`. Download URL at `output.url`.

Supported formats: mp4, mov, avi, webm, mkv, jpg, png, gif, webp, mp3, wav, m4a, aac.

### 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 |

## Integration Guide

Most of the best free AI tools for video editing are designed to slot into workflows you already use. Browser-based tools like CapCut Web, Clipchamp, and Runway ML's free tier require no installation — just sign in and start uploading footage directly from your desktop or cloud storage.

If you're editing on mobile, tools like CapCut and VN Editor integrate directly with your camera roll and support direct publishing to TikTok, Instagram Reels, and YouTube Shorts. For desktop workflows, DaVinci Resolve's free version includes AI-powered features like Magic Mask and Speed Warp that connect with professional export pipelines.

When stacking multiple free tools — for example, using Descript for transcription-based editing and then finishing in CapCut for effects — export in a lossless or high-bitrate format between steps to avoid quality degradation. Most free tools support MP4 export at 1080p, which is sufficient for this kind of multi-tool workflow.

## Best Practices

Getting the most out of free AI video editing tools comes down to understanding their limitations upfront. Free tiers almost always cap export resolution, monthly usage minutes, or cloud storage — so before committing to a tool, check what the free plan actually includes versus what requires an upgrade.

For AI features specifically, always preview results before finalizing. Auto-generated captions, AI-cut detection, and background removal can introduce errors that are faster to catch early than to fix after export. Build a quick review step into your editing routine.

Batch processing is rarely available on free plans, so prioritize tools that handle your most time-consuming task first — whether that's captioning, trimming, or color correction. Use the AI for the heavy lifting and handle fine-tuned adjustments manually to maintain creative control.

Finally, keep a backup of your raw footage before running any AI-based edits. Some browser-based tools process files on their servers, and understanding their data retention policies is worth a quick read before uploading sensitive or proprietary content.
