01 / Overview

How can you color grade a video online?

Choose a clip, correct its exposure and white balance, shape shadows and highlights, then adjust contrast and saturation for the final mood. You can compare the original at any time and export an H.264 MP4. The source video and rendered result remain in your browser.

How to use

  1. 01
    Choose a video

    Drop an MP4, WebM, MOV, MKV, AVI, MPEG, or another common video file into the workspace.

  2. 02
    Balance the image

    Correct exposure, temperature, and tint so neutral objects look believable and important detail remains visible.

  3. 03
    Shape the look

    Choose a starting look or adjust shadows, highlights, contrast, and saturation while the preview plays.

  4. 04
    Compare and export

    Hold Compare to check the source, then render and download the graded MP4 when the treatment feels right.

Who it's for

  • Creators can give phone footage a consistent mood before publishing a short or reel.
  • Remote teams can correct a dim or cool webcam recording without sending internal footage to an upload service.
  • Teachers and presenters can recover shadow detail and tame bright slides in recorded lessons.
  • Small production teams can test a direction quickly before recreating a detailed grade in a desktop editor.

Color correction makes footage look balanced; color grading gives that corrected image a deliberate mood. This workspace combines both stages without burying the useful controls. Start with exposure, temperature, and tint to fix the image. Then use shadows, highlights, contrast, and saturation to shape depth and intensity.

The five starting looks are practical recipes rather than opaque filters. Cinematic cools and deepens the picture, Golden Hour adds warmth, Cool Clean shifts white balance blue, Soft Fade lifts the darker tones, and Punchy increases separation and color. Every preset remains fully adjustable. A press-and-hold comparison removes the preview treatment so you can judge whether the grade helps.

The live preview uses lightweight browser effects for quick decisions. Export loads FFmpeg WebAssembly only when needed and renders the chosen adjustments frame by frame. The result is an H.264 MP4 with the first readable audio track encoded as AAC. Subtitles, extra tracks, chapters, and source metadata are not copied.

FAQ

Is my video uploaded when I color grade it?

No. The selected file stays in this browser tab. A WebAssembly build of FFmpeg applies the final grade locally and creates the downloadable MP4 on your device. The engine code downloads when export begins, but your source and result are not uploaded to CanDoYa.

Is this online video color grading tool free?

Yes. You can use every correction control, compare the grade, render the result, and download it without an account, subscription, credit limit, or watermark. Your device supplies the processing power, so practical limits depend on available memory and the length and resolution of the source.

How large a video can I color grade in the browser?

The conservative limit is 100 MB on mobile or lower-memory devices, 250 MB on a typical desktop, and 500 MB on a high-memory desktop. Files near those limits may process slowly because the browser holds the source, video engine, decoded frames, and output at the same time.

What is the difference between color correction and color grading?

Color correction aims for a neutral, consistent image by fixing exposure, contrast, and white balance. Color grading comes after that and creates a mood, such as a cool cinematic or warm golden look. This tool includes controls for both stages so you can balance first and style second.

What do temperature and tint change?

Temperature moves the overall balance between cooler blue and warmer amber tones. Tint moves between green and magenta, which helps remove a remaining color cast after temperature is set. Use a neutral white or gray object in the frame as a reference, then make small adjustments.

Does the graded video keep its audio?

Yes, when the source has a readable audio track. The exporter keeps the main video and writes the first audio stream as AAC in the MP4. Silent clips remain silent. Extra audio tracks, subtitles, chapters, attachments, and original metadata are intentionally omitted.

Why can the preview differ slightly from the exported video?

The immediate preview uses browser display filters, while export applies FFmpeg color operations to decoded frames. Codec color ranges, gamma handling, and player color management can produce small differences. Watch the exported preview before downloading, especially when you use strong shadow or white-balance settings.

Will color grading reduce video quality?

The picture must be re-encoded so the grade appears in every player. The high-quality H.264 export setting limits visible loss, but any lossy re-encode can change fine detail. Keep the original as your master and avoid repeatedly grading an already compressed exported copy.
