## FAQ

### My video is too dark — which slider should I use?

Start with gamma: it lifts the midtones and brings out shadow detail without blowing out the highlights. If everything is still dark, add a little brightness. Pushing brightness alone tends to make the picture look grey.

### Does the preview match the export?

The preview approximates the result with browser filters, so brightness, contrast, gamma and saturation match closely. Sharpening and denoising are not shown in the preview and only apply to the exported file.

### Are my files uploaded to a server?

No. Everything runs locally in your browser via WebAssembly. Files never leave your computer and are discarded when you close the page.

### Do I need to sign up or pay?

No. The site is completely free, requires no account, has no usage limits and adds no watermarks.
