About Concat Video Editor
Concat Video Editor is a free, user-friendly video editing software designed as a free alternative to CapCut. It offers a complete set of features ranging from auto-captions, voiceovers, and background removal to 4K video export, with no annoying conditions like typical editing software. There are no watermarks upon export, no account registration required, no need to upload files to the internet, and everything is processed locally on your device from start to finish.
The core of Concat is its multi-track timeline that allows video clips, audio, text, and images to be layered on top of each other. You can drag and drop clips into order, trim unwanted parts, detach audio from video, or sync clips directly on the timeline. This provides a single-page overview of the entire project showing what plays and when, allowing you to click on any clip to make immediate edits.
The tools in Concat significantly reduce tedious work. The auto-caption system listens to speech in the clip and converts it into on-screen text, perfect for tutorial or storytelling videos where viewers can read along without turning on the sound. For text-to-speech, simply type the text and let the program generate a voiceover narration without needing to record your own voice. It also features a background removal tool that separates a person from their background to place them onto a new scene without needing a green screen.
Users can also decorate videos with effects and text, including titles, annotations, color and lighting adjustments to make clips from various sources look cohesive, and transitions between clips for smoother scene changes, with instant preview on screen before actual export.
Once editing is complete, the program exports videos in crisp quality up to 4K, making it suitable for both social media clips and projects requiring high-quality files for further use. Whether you are a short-form content creator, a teacher creating educational media, or someone wanting to combine clips from multiple sources into a single professional-looking video without relying on expensive software, requiring accounts, watermarks, or uploading files to the internet.
Who is this program suitable for?
Creators of short-form videos for TikTok, Reels, or Shorts benefit the most because these tasks require fast auto-captions and titles without paying a monthly subscription.
YouTubers and educators are also a great fit. Screen recordings and podcast clips can be edited in the same timeline as other work, while those who write scripts or issue commands via AI agents can use the built-in MCP server and JSON-RPC API to control the editing process.

What's new
Version 0.2.9 – Nov 5, 2026
- Transitions become clips on the timeline that can be placed, moved, and trimmed like regular clips; adjust Push direction, Wipe softness, or Whip speed directly on the transition.
- Transparent background projects display a checkerboard pattern under the preview image, allow custom background colors, and support export with an alpha channel as ProRes 4444 or VP9.
- Chroma key with automatic background color detection, eyedropper, Remove Black, and multi-item editing in the inspector.
- Record your own voiceovers, name them, add images and descriptions directly from the Voices layer.
- Speed curves can be custom-drawn, selected from presets, and adjusted as smooth or linear curves from the Speed tab.
- Style individual words within titles separately with color, bold, italic, underline, strikethrough, font size, uppercase/lowercase, and spacing.
- Auto-captions listen only to the selected language, with each caption starting precisely with the spoken words.
