Fix Video White Balance
Estimate a color-cast correction from the selected reference frame, apply the same gains across the clip, and review the result where lighting or scenes change.
Single reference estimate
The same estimated gains are reused instead of recalculating them per frame. Existing lighting changes, cuts, and source artifacts can remain visible.
Luma-clipped gray-world
Very dark and near-white samples are excluded with fixed luma thresholds. Mixed lighting, saturated colors, and the selected reference frame can still bias the estimate.
Adjustable strength
Dial the correction from subtle to full.
How to fix video white balance
- Open the tool and add your video Select a compatible file for Fix Video White Balance.
- Review and adjust Adjust the strength, process the clip using a reference frame near the selection start, then review the exported result and rerun with a different strength if needed.
- Export and download Review the exported result from Fix Video White Balance, then download it.
Frequently asked questions
Which frame is used for the estimate?
A decoded reference frame near the start of your trim selection. Trim to a representative moment and review the output.
Will it flicker?
The tool computes one correction and reuses it instead of estimating a new correction per frame, which avoids that source of fluctuation. Changes already present in the footage or edit can still remain.
Does it work on night footage?
Extreme single-color scenes can fool gray-world assumptions; lower the strength if the result overshoots.
Will the correction drift or flicker over the clip?
One correction from the reference frame is reused across the clip rather than recalculated per frame. That keeps the applied gains fixed, but lighting changes, cuts, and source artifacts can still make the visible result vary.
Does it replace manual color grading?
It attempts to neutralize a color cast from one reference estimate. Review the result; for creative looks or changing lighting, continue grading in an editor.
How to verify a Fix Video White Balance export
Treat the page preview and the downloaded file as separate evidence. Use a representative clip, keep the untouched source, and record the result that the task actually requires before changing any control.
- Before processing, note the source container, video and audio codecs when known, duration, dimensions, frame rate, orientation, audio-track count, and intended destination. Also record the exact cut, crop, timing, visual correction, or extraction you expect. These observations create a baseline for comparing the export instead of relying on memory.
- Run a short representative sample first and change one setting at a time. Browser codec support, available memory, hardware acceleration, and input structure can affect which processing path is available. A successful preview for one sample shows only that observed case; it does not establish compatibility for every file with the same extension.
- Inspect the preview around the portions most likely to expose defects: the beginning and final frame, cut boundaries, rapid motion, fine text, faces, object edges, gradients, orientation changes, and any section where sound should align with a visible event. For model-assisted tools, look for missed regions, unstable masks, invented detail, or frame-to-frame drift.
- Open the downloaded file in a separate current player rather than reviewing only the in-page preview. Confirm that it starts and ends where expected, plays through without an unexpected stall, and has the intended duration, dimensions, orientation, frame rate, audio presence, and synchronization. Check the file again in the platform or editor that will consume it.
- Compare the exported clip with the untouched source at the same viewing scale and, when useful, matched playback volume. Look for unexpected crops, padding, stretch, softness, banding, halos, color shifts, temporal jumps, repeated or missing frames, and changes in file size or codec that matter to the destination. Decide whether any difference is acceptable for the stated task.
- If the result is missing, fails to play, or differs from the preview, first confirm that the source opens independently. Reload the page, retry with a small controlled sample, reset optional controls, and preserve the exact on-page message. Testing one controlled change at a time makes browser, input, setting, and destination failures distinguishable.
- Record the Fix Video White Balance URL, relevant settings, browser and device, date, source identity, output filename, and observed checks. Keep before-and-after files when the result matters. This record supports a reproducible comparison later and avoids treating a changed input, capability, or destination requirement as the same run.
