Open-source Adobe Media Encoder replacement powered by FFmpeg.
A full-featured local video/audio transcoder with a modern dark UI. No subscriptions, no watermarks, no cloud dependency.
- Batch encoding queue — drag & drop or browse for files
- 16+ built-in presets — H.264, H.265, AV1, VP9, ProRes, GIF, MP3, AAC, FLAC, Opus, WAV
- Per-job preset selection — assign different settings per file
- Live progress tracking — real-time progress bars, FPS, and ETA per job
- Media probing — FFprobe detects resolution, duration, codec, bitrate
- Concurrent encoding — 1–4 parallel jobs (configurable)
- Custom output folders — or output next to source
- Frameless dark UI — custom title bar, keyboard-friendly
- Persistent settings — output directory and concurrency saved across sessions
- Error handling & recovery — clear error messages with retry capability

- Sandbox isolation — Renderer process runs in restricted sandbox
- Context isolation — No direct access to Node.js APIs
- Preload bridge — Typed IPC for all communication
- Input validation — All file paths and payloads validated
- No eval() — No dynamic code execution
See SECURITY.md for detailed security policies and roadmap.
Edit src/shared/presets.ts and add a new entry following the Preset interface from src/shared/types.ts:
{
id: 'my-preset',
name: 'My Preset',
description: 'Custom encoding settings',
category: 'video',
container: 'mp4',
videoCodec: 'libx265',
crf: 28,
preset: 'medium',
format: 'h265'
}The preset will automatically appear in the queue dropdown and Presets browser.
- Ensure you downloaded the official installer, not built from source
- Try reinstalling the app
- Check file format compatibility with chosen preset
- Verify sufficient disk space (output directory)
- Check file permissions
- This is normal for high-bitrate or long files
- Try reducing concurrent jobs in settings
- Close other resource-intensive applications
- Right-click the app → "Open" → "Open" (one-time bypass)
- This is a known macOS security feature; normal for unsigned apps during beta
