Velox Editor docs

Everything you need to install Velox Editor, learn the timeline, and ship a finished render. Start with installation, then explore the features and keyboard shortcuts.

Installation

Download Velox Editor for your platform, then make sure FFmpeg is installed. Velox uses ffmpeg and ffprobe for media import, transcoding, and export, and both must be available on your system PATH.

Get the app. Download the build for your platform from the Velox Editor download page, then follow the FFmpeg steps for your operating system below.

macOS

The simplest route is Homebrew, which installs both binaries and adds them to your PATH automatically:

Terminal
brew install ffmpeg

If you prefer not to use Homebrew, download a static build from ffmpeg.org or evermeet.cx/ffmpeg, then move the ffmpeg and ffprobe binaries into a directory on your PATH, such as /usr/local/bin.

Sign the app before first launch. Because Velox is distributed outside the App Store, macOS Gatekeeper may block it. After moving Velox Editor into your Applications folder, run this once in Terminal, then open the app normally:

Terminal
xattr -cr '/Applications/Velox Editor.app'

Windows

Install FFmpeg with a package manager, which adds it to your PATH for you:

PowerShell
winget install Gyan.FFmpeg
# or, with Chocolatey:
choco install ffmpeg

To install manually, download a build from gyan.dev or ffmpeg.org, extract it, and add the bin folder (the one containing ffmpeg.exe and ffprobe.exe) to your PATH under System Properties, Environment Variables, Path. Restart Velox after changing your PATH.

Linux

Install FFmpeg from your distribution package manager. This places ffmpeg and ffprobe on your PATH:

bash
# Debian / Ubuntu
sudo apt install ffmpeg

# Fedora
sudo dnf install ffmpeg

# Arch
sudo pacman -S ffmpeg

If you run the AppImage build, make it executable first with chmod +x Velox-Editor.AppImage, then launch it. The AppImage still relies on FFmpeg being on your PATH.

Verify the install

Confirm both tools are visible from a terminal. If each command prints a version, Velox will find them:

Terminal
ffmpeg -version
ffprobe -version

Getting started

From a fresh install to a finished render in five steps.

  1. Install and open Velox.

    Follow the installation steps above and confirm that ffmpeg and ffprobe are on your PATH.

  2. Import your media.

    Click Add File or drag video, audio, and images into the Media panel. Velox reads them with ffprobe and auto-transcodes incompatible pixel formats for a browser-safe preview.

  3. Build the timeline.

    Drag clips from the Media panel onto video, audio, image, or text tracks. Snapping and the scrubber help you line everything up.

  4. Edit and add effects.

    Switch tools with keyboard shortcuts, then apply transforms, keyframes, color correction, chroma key, crop, transitions, subtitles, and Script FX overlays.

  5. Export.

    Choose MP4, WebM, or MOV with your resolution, frame rate, and bitrate. Velox uses your GPU encoder when one is available and falls back to CPU automatically.

Features

A tour of what Velox Editor can do, from import to a hardware-accelerated final render.

Multi-track timeline

Video, audio, image, and text tracks with drag-and-drop from the source media panel. Clip snapping, an adjustable scrubber, autosave recovery, and a full undo/redo history keep the timeline fast and forgiving.

Media import

Files are read with ffprobe on import, and incompatible pixel formats (yuvj420p, 10-bit, full-range) are auto-transcoded to a browser-safe form so previews stay accurate.

Playback

Real-time preview with frame-accurate seeking and keyboard shortcuts for scrubbing, play, and pause.

Transform & keyframes

Animate position, scale, rotation, and opacity per property with cubic-bezier easing. Effect keyframes extend animation to color filters and transforms, and they render correctly through the exporter.

Color correction

Temperature, tint, brightness, contrast, saturation, highlights, and shadows, all with a live preview in the editor.

Chroma key

Pull green or blue screen composites with similarity, smoothness, and spill-suppression controls.

Crop

Non-destructive per-edge cropping that never alters your source footage.

Transitions & fades

Fade, slide, zoom, and wipe transitions with directional control and manually adjustable length, plus a visual cubic-bezier editor for fade-in and fade-out curves.

Motion tracking

SSD template matching follows a region you set and bakes the result into position keyframes you can attach to any layer.

Text & titles

Font family, bold, italic, underline, alignment, and a bounding box. A font manager modal lets you browse and select fonts, with accurate italics in both preview and export.

Auto subtitles

Whisper-based speech-to-text generates subtitle tracks. Pick a language, set a minimum-confidence floor, and choose a target track.

Export & GPU acceleration

Export to MP4, WebM, or MOV with configurable resolution, frame rate, and bitrate. Velox auto-detects hardware encoders (VideoToolbox, NVENC, VA-API, QSV, AMF) and falls back to CPU automatically. Longer renders show a formatted time estimate.

Project & history

Save and open projects with autosave recovery. Detach audio from a clip, delete imported source media from the media panel, and step through a full undo/redo history at any time.

Keyboard shortcuts

Velox is built for a keyboard-first workflow. Press a tool key to switch instantly, scrub with the spacebar and arrows, and drive the whole project without leaving the timeline.

On macOS the modifier is Cmd. On Windows and Linux use Ctrl for the same actions.

Scriptable clips

Script FX is the headline feature of Velox: drop a Script FX clip on the timeline and program a custom overlay in JavaScript, from animated graphs and live waveforms to lower-thirds and generative backgrounds. Everything runs in a sandboxed worker and renders frame-for-frame into your export.
