Video Filters & Effects

A LUT (Look-Up Table) is a file that maps every possible input color in a video to a specific output color. Colorists use LUTs to apply a consistent grade across a whole project. The file format is usually .cube — a simple text file with a 3D grid of RGB values. Uploading the same LUT to the same footage gives you the same result every time, which is why productions standardize on LUTs.

A filter is typically a formula — something like 'increase saturation by 50%, add sepia'. A LUT is a lookup: for every input color, it tells the renderer what the output color should be. Because LUTs are precomputed tables, they can encode complex transforms (teal/orange color grading, Rec.709 → Log conversion, film emulation) that pure formula-based filters can't cleanly express. On AICreate, CSS-style effects and LUTs live in the same tool so you can pick whichever is closer to the look you want.

The Adobe .cube format is a plain-text 3D LUT spec. Each file declares a size (e.g. LUT_3D_SIZE 33 means a 33×33×33 grid = 35,937 RGB triplets), a domain (input range), and then the table of output RGB values line by line. Because it's plain text, you can open any .cube file in a text editor and see exactly what the LUT does. AICreate supports sizes 2-33 and the standard [0,1] domain.

Three common ways: (1) Grade a still reference frame in DaVinci Resolve, Photoshop, or Affinity Photo, then export the grade as a .cube. (2) Use a LUT generator (e.g. 3D LUT Creator, Lattice, IWLTBAP LUT Generator) to dial in color curves directly. (3) Convert a preset from one app to .cube via a converter — most color tools export .cube natively. AICreate accepts any valid .cube file ≤5MB with size 2-33. We store uploaded LUTs in your browser's IndexedDB, so they stay on your device and persist between sessions.

We ship 13 free curated LUTs in the LUT tab (teal/orange, moody noir, golden hour, pastel summer, cold neon, bleach bypass, kodachrome vibe, arctic blue, and more — all procedurally generated, MIT-licensed). For more variety, try free packs from RocketStock, IWLTBAP, LutsCC, and Lookslike — always read the license; some are free for personal use but not commercial. Any .cube file you drop into AICreate works.

Intensity blends the LUT output with the original color. At 100% you get the full graded look; at 50% you're halfway between the raw video and the LUT; at 0% the LUT has no effect. Most cinematic grades look best at 70-90% — full strength can over-saturate or crush shadows on already-graded footage.

23 preset effects in 3 categories plus a LUT tab. Visual Effects: pixel art, vintage, vignette, sharpen, soft blur, negative, mirror. Distortion: glitch, film grain, chromatic aberration, VHS, scanlines, camera shake. Color Grading: teal/orange, moody, bright, B&W cinema, sepia, high contrast, desaturated, warm, cool, faded. LUT tab: 13 curated .cube LUTs plus your own uploads.

Your video is processed entirely in your browser using WebGL fragment shaders + MediaRecorder. Each frame is drawn through a shader (color grade, LUT sampler, effect-specific pass), then re-encoded. Nothing is uploaded to any server. The Canvas2D fallback kicks in on very old browsers but skips the LUT path.

No hard limit since everything runs locally. Longer videos take longer to process (about 1x real-time speed).

Not yet in one pass — pick one effect or one LUT per run. You can download and re-upload to apply another effect. We're working on multi-effect chaining.

Yes, but processing time scales with video length. A 1-minute video takes about 10-15 seconds. 10 minutes might take 2-3 minutes.

None. The output is your video with the effect applied — nothing else added.
