FrameTrellis v1.0.0 Is Here: An Open-Source, Local-First Video Editor

Today, I'm excited to announce FrameTrellis v1.0.0, the first stable release of my open-source desktop video editor.

FrameTrellis is a project I've been building around a simple idea: video editing should be accessible through a native desktop application, with users remaining in control of their media and projects.

Your media stays on your computer. FrameTrellis requires no account, cloud processing, telemetry, or advertising.

What is FrameTrellis?

FrameTrellis is a local-first, multi-track video editor built with C++20, Qt 6/QML, MLT, and FFmpeg.

The first stable release focuses on practical editing workflows, reliable project handling, and local rendering.

What can you do with it?

The v1.0.0 release includes:

• Multi-track editing: Arrange video and audio clips, move them between tracks, trim edges, split clips, and perform ripple deletes.
• Real-time preview: Preview footage with synchronized audio, frame stepping, and frame-accurate timecode.
• Audio tools: View audio waveforms and adjust clip volume, fades, and mute settings.
• Transitions and picture adjustments: Apply dissolves, audio crossfades, opacity changes, brightness, contrast, and saturation adjustments.
• MP4 export: Render H.264 video with AAC audio, with quality settings, presets, progress reporting, and cancellation.
• Project recovery: Work with validated .ftproj project files, 500-step undo/redo, automatic saving, crash recovery, and missing-media relinking.

The Windows release also includes both an installer and a portable ZIP package.

Where can you run it?

FrameTrellis v1.0.0 provides Windows x64 packages for Windows 10 version 1809 or later and Windows 11.

Linux users can build the application from source. Linux packages are not available yet, and macOS is not supported in this release.

There are also features still on the roadmap, including titles, subtitles, keyframes, proxy media, and additional export formats. MP4 with H.264/AAC is currently the only export format.

I want to be transparent about these limitations because a first stable release is a milestone, not the end of development.

Feedback is welcome

I'm especially interested in feedback about the editing workflow, timeline usability, playback, export reliability, installation, and anything that feels confusing or doesn't work as expected.

Bug reports, testing, documentation improvements, and contributions are welcome through GitHub.

What do you think an open-source video editor should prioritize next: timeline usability, playback performance, proxy media, or additional editing tools?

Thank you to everyone who explores the project and shares feedback. This is the beginning of the next stage of FrameTrellis.
