LuttieColor grade video. In your browser.
Apply your colour grade and film effects to an entire video — directly in the browser. Preview it before you commit. Export an MP4 when you're happy. No DaVinci Resolve, no Premiere Pro, no plugins.
Requires Chrome or Edge 94+ · No audio in current version · Film effects included
How it works
Grade once. Preview. Export.
Load your video
Drop an MP4, MOV, or WebM file into Luttie. Use the frame picker to extract a representative frame for grading.
Grade the frame
Build your colour grade using curves, colour wheels, HSL secondaries, or AI Grade. Add grain, halation, and bloom from the Film Effects section.
Preview or export
Hit Preview to render your grade across every frame and watch it back in the browser before committing. When you're happy, hit Export to download the MP4.
Or export a LUT instead
For longer projects, export your grade as a .cube LUT and apply it to your full timeline in DaVinci Resolve, Premiere Pro, or Final Cut Pro in one click.
Video export vs LUT export — which to use
Use video export when…
- ✓You need a graded file fast — no NLE setup
- ✓You're delivering a short clip (social, reel, client preview)
- ✓You want to preview the grade across the full clip before exporting a LUT
- ✓Your timeline is under 2 minutes and audio isn't critical
Use LUT export when…
- ✓Your project is longer than 2 minutes
- ✓You need audio in the final file
- ✓You're applying the same grade to multiple clips
- ✓You're working in DaVinci Resolve, Premiere Pro, or Final Cut
Everything applied to the video
Every parameter visible on the canvas — colour grade and film effects — is applied frame by frame to the exported video.
Colour grade
Temperature, tint, brightness, contrast, saturation, vibrance, blacks, whites — all applied per-frame.

How does video export work in the browser?
Luttie uses the WebCodecs API — a browser-native video encoding/decoding API available in Chrome and Edge 94+. For each frame, Luttie runs your colour grade and film effects through a WebGL shader, then re-encodes the processed frames into an H.264 MP4 using a JavaScript muxer. No server, no upload — everything runs locally on your machine.
What video formats does Luttie support for export?
Input: MP4, MOV, WebM (any format the browser's HTMLVideoElement can play). Output: H.264 MP4 at 30fps. The output format is designed for maximum compatibility — it plays in every browser, phone, and NLE.
Does the exported video include audio?
Not in the current version. Video export in Luttie is colour-only — the exported MP4 contains the processed video track without audio. If your project needs audio, export the graded video and combine it with the original audio track in your NLE or a tool like FFmpeg.
What is the maximum video length?
Currently 2 minutes. This is a practical limit — the export processes frames sequentially on the main thread, so longer videos would block the browser for too long. We'll extend this limit as we move frame processing to a background worker.
What browser do I need for video export?
Chrome 94+ or Edge 94+. Safari 16.4+ has partial WebCodecs support. Firefox does not currently support WebCodecs. If you're on an unsupported browser, Luttie still shows the grade in the canvas — you can export a .cube LUT and apply it in your NLE instead.
Should I use video export or LUT export?
It depends on your workflow. Video export is ideal for quick turnaround — social content, short clips, client previews where you need a graded file fast without opening a separate NLE. LUT export is better for longer projects — apply the same grade to a full timeline in DaVinci Resolve or Premiere Pro in one click. Many users use both: video export for a quick preview, then LUT export for the final deliverable.
Do film effects (grain, halation, bloom) apply to the exported video?
Yes. Everything visible on the canvas — colour grade and film effects — is applied to every frame of the exported video. The grain is static per-pixel in this version (the same noise pattern on every frame). Animated per-frame grain is on the roadmap.
