OpenShorts.app

Open source AI video platform with 3 tools in one: Clip Generator, AI Shorts (UGC videos with AI actors), and YouTube Studio.

Your podcast, and the vertical clip OpenShorts makes of it: both speakers stacked, captions on the seam

Two people on camera? OpenShorts stacks them instead of shrinking the wide shot, puts the captions on the seam where they cover nobody, and switches back to a face-tracked crop when the cut goes to one person. The AI picks the layout per video; nothing to configure.

Two ways to run it, same software either way:

Self-hosting is genuinely free and always will be. It costs you a machine, your own API keys and the time to keep it running. The hosted plans exist to cover that hardware and those keys, not to unlock features.

Complete free AI YouTube toolkit: thumbnails, titles, descriptions, and direct publishing.

• AI thumbnail generator with face overlay
• 10 viral title suggestions with refinement chat
• Auto-generated descriptions with chapter timestamps
• One-click publish to YouTube

UGC Video Gallery

All generated videos and avatars are saved to a public gallery with SEO pages for each video.

UGC Gallery

• Public gallery page with hover-to-play (/gallery)
• Individual SEO video pages with og:video meta tags (/video/{id})
• JSON-LD structured data for search engines
• Avatar gallery with prompt history

Key Features

Clip Generator

• Viral Moment Detection: Google Gemini 3.1 Flash-Lite analyzes transcripts and scene boundaries to detect 3-15 high-potential moments
• Runs fully local if you want: point LLM_BASE_URL at Ollama, LM Studio, vLLM or any OpenAI-compatible server and the moment picker runs on your own model, no Google key needed (see Run without a Google key)
• Smart 9:16 Cropping: AI reframing per scene — TRACK mode (MediaPipe + YOLOv8 face tracking), GENERAL mode (blurred background), SPLIT mode (two speakers stacked, captions on the seam) and SCREENCAST mode (screen over presenter); the layout is picked per video by Gemini or forced from the dashboard
• Auto Subtitles: faster-whisper with word-level timestamps, styled and burned into clips
• AI Voice Dubbing: ElevenLabs integration for 30+ languages with voice cloning
• Hook Text Overlays: AI-generated attention-grabbing text overlays
• AI Video Effects: Gemini-generated FFmpeg filters for professional effects

OpenShorts vs Competitors

How Much Does It Cost?

Self-hosting OpenShorts is free. You provide the machine and you only pay for the AI APIs you use, and most have generous free tiers:

Bottom line: You can clip videos for practically free with Gemini, and publish 10 videos/month to all social networks at zero cost with Upload-Post.

Don't want to run any of that? openshorts.app is the same software on our hardware: our NVIDIA GPU clips an 8-minute video in about 50 seconds instead of the 5 to 8 minutes it takes on a typical CPU, the Gemini key is included, and auto-publishing is already wired up. Free plan is 20 minutes a month with a watermark and no credit card; paid plans start at $12/mo for 100 minutes without watermark.

Requirements

• Docker & Docker Compose
• Google Gemini API Key (Free — get it here) — required for all AI features
• fal.ai API Key (Pay-per-use) — required for AI Shorts (actor generation, video, lip-sync)
• ElevenLabs API Key (Free tier) — required for voiceover/dubbing
• Upload-Post API Key (free tier) — required for direct social posting

Getting Started

1. Clone

git clone https://github.com/mutonby/openshorts.git
cd OpenShorts

2. Configure (optional)

cp .env.example .env
# Edit .env with your AWS keys for S3 backup

3. Launch

docker compose up --build

4. Open Dashboard

Navigate to http://localhost:5175

1. Go to Settings and enter your API keys (Gemini, fal.ai, ElevenLabs, Upload-Post)
2. Clip Generator: Upload a long-form video to generate viral shorts
3. AI Shorts: Describe your product or paste a URL to generate UGC marketing videos
4. YouTube Studio: Generate thumbnails, titles, and descriptions for YouTube
5. UGC Gallery: Browse all generated videos and avatars

5. GPU acceleration (optional, NVIDIA)

The default image is CPU-only. With an NVIDIA card (any card with NVENC, e.g. RTX 4060) an 8-minute video clips in about a minute instead of 5 to 8. Nothing is passed through in the VM sense — the container just gets access to the host GPU.

Host: install the NVIDIA driver (nvidia-smi must work) and the NVIDIA Container Toolkit:

sudo nvidia-ctk runtime configure --runtime=docker && sudo systemctl restart docker
docker run --rm --gpus all nvidia/cuda:12.4.0-base-ubuntu22.04 nvidia-smi   # sanity check

On Windows use Docker Desktop with the WSL2 backend and the Windows NVIDIA driver; no driver inside WSL.

Compose: create docker-compose.override.yml next to docker-compose.yml (picked up automatically). GPU: "1" adds cuBLAS/cuDNN and onnxruntime-gpu to the image (~2 GB); video is required for NVENC.

services:
  backend:
    build:
      context: .
      args:
        GPU: "1"
    deploy:
      resources:
        reservations:
          devices:
            - driver: nvidia
              count: all
              capabilities: [gpu, video]

.env:

WHISPER_MODEL=large-v3-turbo
WHISPER_DEVICE=cuda
WHISPER_COMPUTE=float16
FFMPEG_ENCODER=auto           # probes h264_nvenc at startup, falls back to x264
TRANSCRIBE_BACKEND=parakeet   # optional: ~2x faster than whisper, 25 European languages, auto-falls back to whisper
ASR_GPU_CONCURRENCY=1

Verify:

docker compose up --build -d
docker exec openshorts-backend nvidia-smi -L
docker exec openshorts-backend ffmpeg -hide_banner -f lavfi -i testsrc=size=256x256:rate=1 -frames:v 1 -c:v h264_nvenc -f null -

The backend log on the first job reports the chosen encoder and transcription device. A CUDA error in whisper (e.g. VRAM exhausted) retries once on CPU automatically. 8 GB of VRAM is enough for large-v3-turbo fp16 plus the detection models.

6. Run without a Google key (local LLM, optional)

The only cloud call in the clip pipeline is the moment picker: it sends the transcript (never the video) to Gemini. Point it at any OpenAI-compatible server instead and the whole pipeline stays on your box:

# .env
LLM_BASE_URL=http://host.docker.internal:11434/v1   # Ollama on the host
LLM_MODEL=qwen2.5:14b                                # any chat model that follows instructions
# LLM_API_KEY=...                                    # only if your server checks one (vLLM --api-key, OpenRouter)

Works with Ollama, LM Studio, vLLM, llama.cpp server, LocalAI and OpenRouter. The dashboard stops asking for a Gemini key when this is set. Two things to know:

• Context length. A scoring call carries three transcript windows (~2-3k tokens) and the detail call up to ten (~5k on a long podcast). Ollama defaults to a 4096-token context and truncates silently, so run it with OLLAMA_CONTEXT_LENGTH=16384 (or set num_ctx in a Modelfile); raise LLM_SCORE_BATCH above 3 only if your context allows it. 7-8B models return valid JSON reliably, 3B ones do not.
• What still needs Gemini. Anything that has to look at frames: the automatic layout picker (AUTO_LAYOUT), the on-screen content detector and silent videos (no speech to clip by). Without a Gemini key those fall back to the plain face-tracking crop, and a silent video fails with a message that says so. Add a key alongside LLM_BASE_URL and you get both.

Automate It: MCP Server, REST API and Webhooks

You don't need the dashboard. The whole pipeline is callable by AI agents and scripts.

MCP server (/mcp)

OpenShorts ships a built-in MCP server, so Claude, ChatGPT, Cursor or any MCP client can clip and publish videos for you:

claude.ai and ChatGPT: paste https://mcp.openshorts.app/mcp as a custom connector (Settings → Connectors) and approve the access on openshorts.app. The server does OAuth 2.1 with dynamic client registration, so there is no key to copy; the connection shows up under Account → API keys, where revoking it disconnects the app.

# Claude Code / Cursor / n8n (hosted): create an API key in your account page
claude mcp add --transport http openshorts https://mcp.openshorts.app/mcp \
  --header "Authorization: Bearer osk_..."

# Self-hosted (no key needed, BYOK rules apply):
claude mcp add --transport http openshorts http://localhost:8000/mcp

# Self-hosted without running the web server: same tools over stdio
claude mcp add openshorts -- python mcp_stdio.py

Tools: process_video (URL or upload_id; captions: false when the source already has subtitles, auto_hook: false to skip the hook line, burned by default like the dashboard), create_upload (hand the agent a local file: PUT the bytes, then process), get_job_status, list_clips, get_quota, add_subtitles, recut_clip, publish_clip. A prompt like "clip this podcast and schedule the best 3 to TikTok" is now a one-liner in your agent of choice.

REST API + API keys

Hosted accounts can mint osk_... API keys (account page). A key authenticates as you everywhere — same plan, same minutes, same job ownership:

curl -X POST https://api.openshorts.app/api/process \
  -H "Authorization: Bearer osk_..." -H "Content-Type: application/json" \
  -d '{"url": "https://youtube.com/watch?v=...", "acknowledged": true,
       "webhook_url": "https://your-server.com/hooks/openshorts"}'

Interactive docs at /docs (OpenAPI) on any instance.

Completion webhooks

Pass webhook_url (and optionally webhook_secret) to POST /api/process and you get exactly one POST when the job reaches a terminal state — no polling loops in your n8n / Zapier / cron pipelines:

{"event": "job.completed", "job_id": "…",
 "clips": [{"index": 0, "title": "…", "video_url": "…", "download_url": "…"}]}

With a secret, the body is signed: X-OpenShorts-Signature: sha256=<hmac-sha256(body)>.

CLI

The same API from the terminal, zero dependencies (cli/):

pip install openshorts   # or: uvx openshorts

export OPENSHORTS_API_KEY=osk_...              # hosted
# export OPENSHORTS_API_URL=http://localhost:8000   # self-hosted, no key

openshorts process "https://youtube.com/watch?v=..." --wait
openshorts clips <job_id>
openshorts publish <job_id> 0 --platforms tiktok,youtube

Agent skill

skills/openshorts/SKILL.md follows the open Agent Skills standard, so it works in any skill-capable agent:

# Claude Code (and most agents): copy the folder into the skills directory
cp -r skills/openshorts ~/.claude/skills/

# Hermes Agent: install straight from this repo
hermes skills install mutonby/openshorts/skills/openshorts

# OpenClaw: from ClawHub
openclaw skills install @mutonby/openshorts

n8n

An importable workflow (video URL in, published-ready clips out, no polling) lives in examples/n8n/.
