Frequently Asked Questions
How It Works
The Color Adjustment tool uses FFmpeg WebAssembly with a chain of video filters to modify pixel values across the entire color spectrum. The tool applies adjustments through FFmpeg's eq (equalizer), colorbalance, curves, and unsharp filters.
Brightness is applied by adding a constant value to all pixel channels. Contrast scales pixel values around the midpoint (128). Saturation adjusts the color intensity by scaling the chrominance components (U and V in YUV space). Gamma applies a power-law correction to handle perceived brightness non-linearity.
The temperature filter shifts the color balance along the blue-orange axis. Sharpness uses an unsharp mask convolution kernel to enhance edge contrast. Each filter is chained in FFmpeg's filtergraph, and adjustments are applied sequentially from left to right. The entire pipeline is hardware-accelerated when possible via WebAssembly SIMD instructions.
Tips & Best Practices
- Subtle adjustments: Small changes (5-10%) look professional. Large adjustments (30%+) often look amateurish and introduce noise.
- Use presets first: The built-in Enhance, Warm, Cool, and Vintage presets provide excellent starting points that you can fine-tune.
- Fix white balance with temperature: If your video has a blue or orange tint, adjust the temperature slider to neutralize it.
- Boost saturation carefully: Over-saturated colors clip to pure red/green/blue, losing detail. Stay under 30% boost for natural results.
- Apply brightness last: Brightness adjustments should be the final step after contrast and saturation are set.
- A/B comparison: Toggle the preview on/off frequently to ensure your adjustments are actually improving the image.
