## Introduction
Kdenlive (KDE Non-Linear Video Editor) has been developed since 2003 as part of the KDE project. It provides a professional-grade editing environment with multi-track timelines, keyframeable effects, and integration with the MLT multimedia framework, all without any licensing fees.

## What Kdenlive Does
- Edits video on an unlimited multi-track timeline with audio and video separation
- Applies over 200 video and audio effects including color correction, transitions, and compositing
- Supports proxy clip workflows for smooth editing of high-resolution footage on modest hardware
- Provides a built-in titler for text overlays, lower thirds, and animated title sequences
- Renders output using FFmpeg with presets for YouTube, Vimeo, DVD, and custom formats

## Architecture Overview
Kdenlive is built with C++ and Qt, using the MLT framework as its core media engine. MLT handles decoding, effects processing, and encoding through its plugin system, with FFmpeg providing the codec layer. The project file is XML-based, and the application supports KDE integration including theme support and file management. GPU-accelerated effects use OpenGL via the movit library.

## Self-Hosting & Configuration
- Install via Flatpak for the latest version on any Linux distribution
- Enable proxy clips in Project Settings to generate low-resolution editing copies of large source files
- Configure render profiles in the Render dialog to add custom FFmpeg encoding presets
- Set up keyboard shortcuts in Settings > Configure Shortcuts to match your preferred editing workflow
- Use the speech-to-text feature for automatic subtitle generation from audio tracks

## Key Features
- Multi-track timeline with unlimited audio and video tracks and nested sequences
- Keyframe animation on all effect parameters with bezier curve interpolation
- Online resources integration for downloading effects, transitions, and title templates
- Automatic scene detection for splitting long clips at cut points
- Speech-to-text subtitle generation using Whisper or Vosk models locally

## Comparison with Similar Tools
- **Shotcut** — similar MLT-based editor with a different UI philosophy; Kdenlive has deeper KDE integration
- **DaVinci Resolve** — more powerful for color grading and VFX, but closed-source and heavier
- **OpenShot** — simpler interface suited for quick edits; Kdenlive offers more advanced features
- **Olive** — newer open-source editor with a modern node-based compositor, but still in development

## FAQ
**Q: Can Kdenlive edit 4K video?**
A: Yes. Use proxy clips for smooth timeline editing, then render at full resolution for the final output.

**Q: Does Kdenlive support GPU acceleration?**
A: Kdenlive uses GPU-accelerated effects via OpenGL and supports hardware-accelerated encoding (NVENC, VAAPI) during export.

**Q: Is Kdenlive stable for professional work?**
A: Recent versions have significantly improved stability. Auto-save and backup project files protect against crashes.

**Q: Can Kdenlive generate subtitles automatically?**
A: Yes. Kdenlive includes speech-to-text integration using local Whisper or Vosk models for automatic subtitle generation.
