RGB split effect for video and photos

Knock red and blue out of line, like a worn videotape: set the split with the sliders and compare it with the original, then open your own video or photo and export it at full resolution. It runs in your browser: your file is never uploaded.

How to add an RGB split to a video online

  1. Open your video or photo

    Choose Open your own file: the editor opens with the effect, ready for your file (videos as MP4, MOV, M4V, WebM, MKV; photos as JPEG, PNG, WebP, AVIF). It opens in your browser, and nothing is uploaded.

  2. Set the split and compare

    Amount sets how far red and blue part and Angle which way. Compare shows the original beside the result.

  3. Export it

    In the editor, export the video as MP4 or WebM, or the photo as PNG, JPEG or WebP, at its full resolution, with no watermark.

Amount and Angle

Amount sets how far red and blue part, from 0 to 100, where they are 1.5% of the frame's shorter side apart, about 16 pixels on a 1080p frame; green stays where it is. As a share of the frame, the split looks the same in the small preview, a 4K export and a vertical video.

Angle sets which way they go, counter-clockwise on screen: at 0 red moves right and blue left, at 90 red up and blue down.

RGB split, chromatic aberration and glitch

An RGB split shifts red and blue the same distance everywhere. Chromatic aberration grows from nothing at the centre to the edges of the frame, as from a lens, and a glitch tears the picture into bands with their colours split, changing from moment to moment. The editor has all three, and each has a page of its own.

Where an RGB split shows

The split shows along strong edges: posts and branches against the sky, a face against a dark background, lights and signs at night. Flat, even areas hardly change.

It stays the same on every frame, with no wobble or jitter of its own, and the export matches the preview. MP4 and WebM files keep colour at a lower resolution than brightness, as most video does, so the finest fringes soften a little there; a PNG keeps them exactly.

Your files stay on your device

Everything happens right on your device, in your browser. Your videos and photos are opened, edited and saved there, and never sent anywhere.

Because nothing is uploaded, your files are safe: nothing can leak, and no one else, not even us, ever sees them. You don't need an account: one holds only your email address and the AI agents you let in, and signing in keeps a single cookie. An agent's instructions to your editor pass through our server and are deleted as soon as the editor has carried them out; your files never do. Without cookies, the site counts visits and a few choices, such as a preset or effect you pick and the format you export to, but never which files you open or anything in them.

Exports leave out hidden details such as where a video was recorded, and a shared link carries only your settings, never your file.

Files and browsers

Opens MP4, MOV, WebM and MKV videos and JPEG, PNG, WebP and AVIF photos, and exports MP4 or WebM, or PNG, JPEG or WebP, at full resolution, keeping the original sound where the browser can. Works in current Chrome and Edge on a computer or Android, in current Firefox on a computer and in Safari 26 or later; HDR video is converted to standard range.

The Retro VHS preset puts an RGB split in a worn-videotape look. It opens the editor with it:

Questions about the RGB split effect
