How Remuxe makes every copy of your video unique

Post the same video twice and platforms notice. They compare what a video looks and sounds like — and how the file is built — against what they've already seen. An exact copy matches. So does a copy with a filter on top, because one filter changes every frame the same way, and fingerprints are built to survive that.

Remuxe takes a different approach: it changes many small things at once, differently on every frame and differently in every copy. To your viewers, each copy looks and sounds like the original. To a fingerprint, it's a new file.

The core: a different change on every frame

Most “uniquifier” tricks apply one setting to the whole video: +3% brightness, a 2% crop, a mirror. That's one change, repeated on every frame, and it's exactly the kind of change fingerprints are built to ignore.

Remuxe moves something on every frame, and something different each time. On one frame it's brightness, on the next contrast, then gamma, saturation, temperature — fifteen picture values in turn:

Each step is between 0.5% and 1% — below what people notice, even side by side — and one color channel (red, green or blue) moves along with it. On top of that, the whole picture shifts by a fraction of a pixel and gets a layer of micro noise.

Every copy starts from its own random seed, so copies differ from each other, not just from the original. Make ten copies and you get ten different sequences of changes.

The sound

Sound is fingerprinted too, and it's often overlooked. By default, every copy gets three changes you won't hear:

• frequencies above 17.5 kHz are cut — above what most adults can hear;
• the pitch moves by 0.2%;
• the samples get a light dither.

If you'd rather keep the sound exactly as it is, set the sound to Keep.

The file

Every copy is a brand-new video file, written from scratch: new container, new timing, freshly encoded frames. Nothing from the source file is carried over, and each copy gets its own file details: by default a real phone model, lens and location picked at random for that copy (never your own), or a real phone's details when you use Phone look. More on the file side in Why Remuxe removes AI metadata tags.

Phone look: shot on a real phone

Phone look makes a copy look like it was filmed on a specific phone. It copies that phone's character from a real phone's profile:

• color curves, white balance, saturation, gamma and contrast;
• its sharpening and vignette;
• sensor noise and chromatic aberration;

and the file side too: the phone's file details, its container format and its audio bitrate. You can vary the profile per copy, so no two copies come from exactly the same “camera.”

Fine-tune: more techniques when you want them

The default is designed to be invisible. Fine-tune adds techniques you can switch on one by one:

Every picture technique is tested before it ships, on the GPU and on the CPU fallback, and fails the test if it shifts colors or leaves anything a viewer could see.

Variety on top, per copy

Two switches make copies differ visibly, if you want them to:

• Random look: a slight random color grade on each copy.
• Random effect: one random effect from the library on each copy, faint by default (5% strength, adjustable from 1 to 100%).

On Pro you can make up to 50 copies of each video in one export; Free exports up to 5 videos at a time.

The editor, when you want visible changes

Remuxe is also a full editor, and every edit runs through the same pipeline as the unique copies:

• 85 effects in nine categories — light and glow, retro and film, glitch, distortion, stylize, vision, motion and camera, weather and particles, patterns — up to three layers at once, each with its own strength;
• 15 color looks and 19 color sliders, from brightness and contrast to temperature, tint and vignette;
• framing: 9:16, 4:5, 1:1 or 16:9, with a blur fill, crop to fill or black bars, plus position, zoom, rotation and crop;
• text, images and GIFs on top of the video;
• speed from 0.25× to 4×, trimming and cuts on a timeline;
• sound: 11 presets and a 10-band EQ, music, a leveler, noise reduction, reverb, echo, stereo width and fades;
• auto captions (Pro): word-by-word captions in seven styles;
• copies of a video: duplicate a clip and give each copy its own edit, for hand-made variants.

Video Combinations

Combine two videos in one frame — top and bottom, side by side, picture in picture or a circle — or join clips one after another. “Generate” builds up to 100 variants at once: one fixed video with each of the others, every pair, or an intro and outro around each video. Each variant keeps its own settings.

• top and bottom
• side by side
• picture in picture
• a circle
• one after another

Batch export, on your computer

Drop a folder, choose how many copies you want of each video, and export them all at once with tidy file names (01video, video01, video1 or 1video). Pick 720p, 1080p or the original resolution.

Everything runs in your browser: the frames are processed on your GPU and encoded with your computer's video encoder. Your videos are never uploaded.

What no tool can promise

Unique files are one part of it. Platforms also look at what a video shows and how accounts behave. Post videos you own or have the rights to, follow each platform's rules, and don't flood a platform with the same clip. Remuxe makes every copy a different file; what happens next is still up to the platform.
