Batch Colour Grading — LUTs & Colour Correction
Give multiple videos a consistent look with free batch colour grading. Select MP4, MOV or WebM clips, apply the same LUT and exposure, contrast, saturation, temperature and tint adjustments, and preview each video. Export separate colour-graded MP4s up to 4K, individually or together as a ZIP. Use display-ready SDR footage; camera log needs a suitable conversion LUT.

Accepts MP4, MOV, WEBM
The LUT is applied first, then manual adjustments. Uploaded LUT files stay on your device and are not included in shared URLs.
Exports prioritise high quality and speed over file size. Original resolution keeps source detail; choosing a lower export height resizes the video.
Processing runs entirely in your browser. No file is uploaded anywhere.

Frequently asked questions
Will batch colour grading reduce video resolution or quality?
Original resolution is the default, preserving each clip’s source dimensions and frame timing. A generous H.264 bitrate scales with the export resolution and frame rate to preserve fine detail. Exports prioritise image quality and speed over small files, using GPU grading and hardware encoding when supported. Choose 720p, 1080p or 4K only when you want to limit export height. Grading involves re-encoding, so the output is not mathematically lossless.
How do I batch colour grade multiple videos online?
Select several MP4, MOV or WebM videos, optionally load a .cube LUT, and set your colour correction once. Choose any selected clip to preview the shared look. Process the batch to apply the same LUT and adjustments to every video. Download each completed MP4 separately or download all completed videos as a ZIP. Clips are processed one at a time on your device; they remain separate videos.
Why use batch color grading for a video project?
Batch color grading reuses a creative look across interviews, social videos, product footage or a sequence of clips, saving repeated setup. It applies the same settings to every clip, rather than automatically matching different cameras or lighting conditions. If some shots need individual exposure or white-balance corrections, process them in a separate batch with their own settings.
Can I colour grade and export 4K videos in my browser?
Yes. Choose 4K to keep footage up to 2160 pixels high, with its aspect ratio preserved. Smaller inputs are not upscaled. The output is an H.264 MP4 with compatible audio retained. 4K and large batches need more memory and processing time, and depend on your browser and hardware encoder. Start with a short clip to check device support.
How do I apply a LUT to a video online?
Select a supported MP4, MOV or WebM video, load a 3D .cube LUT, adjust LUT strength and inspect the preview. Process the video to download an H.264 MP4. The tool supports LUT sizes from 2 to 65 and optional DOMAIN_MIN and DOMAIN_MAX values; 1D LUTs and other LUT formats are not supported.
Can I color correct video without a LUT?
Yes. Use the exposure, contrast, saturation, temperature and tint sliders to adjust your video manually. The preview plays your video with sound off by default; exporting applies the same adjustments to every video frame and keeps compatible audio.
Does this color grading tool support HDR or log footage?
This tool grades SDR canvas pixels and exports SDR MP4. It is not a color-managed HDR workflow. For log footage, use a LUT designed for your camera and an SDR output. A creative LUT alone may not convert log footage correctly.
Is online video color grading private and free?
Yes. Single-video and batch colour grading are free, with no account, login, ads or watermark. Your videos and LUT are processed in your browser and never uploaded to Tellers servers. Use a browser with H.264 WebCodecs encoding, such as current Chrome or Edge. Completed videos remain in browser memory until you replace the selection, change the grade or close the page.
