What does Video Color Adjuster do?
Video Color Adjuster is for straightforward global changes to a short clip. Start from Original, Brighter, Higher Contrast, More Saturated or Muted, then fine-tune the four labeled controls. A real rendered frame lets you check the export filter without relying on a CSS approximation.

Practical uses
- Brightening a dim preview copy
- Reducing oversaturated color
- Matching basic contrast for a short clip
Browser and media limitations
- Adjustments apply globally, without masks or scene-specific grading.
- Export re-encodes video and audio and may change file size.
- This is not HDR-aware tone mapping or color-managed mastering.
- The preview shows the first frame, not every lighting condition in the clip.
- Large/high-resolution video can exceed browser memory; start with short clips.

Your media is processed in this browser tab, not uploaded to a processing server. Page navigation, analytics and downloads of application/runtime code still use network requests. Download the result before closing the tab.
Frequently asked questions
Does the preview use the real export filter?
Yes. Preview adjusted frame renders the first frame with FFmpeg's eq filter using the same color settings as export.
Will audio remain in the MP4?
Yes, when the source has audio. The first audio stream is encoded as AAC; it is not copied losslessly.
What does Original reset?
It restores brightness to zero and contrast, saturation and gamma to one. Reset adjustments also clears the previous processed result.
Can this repair blown highlights or do professional grading?
No. Missing highlight detail cannot be reconstructed by these controls, and the tool does not offer masks, scopes or a managed grading pipeline.
