Frequently Asked Questions

Video color correction is the process of adjusting the colors, brightness, contrast, and other visual properties of video footage to achieve a desired look or fix color issues. It involves modifying parameters like brightness (lightness/darkness), contrast (difference between light and dark), saturation (color intensity), and gamma (mid-tone brightness) to improve video quality or match specific aesthetic goals.

Use video color correction when your footage appears too dark or bright, lacks contrast, has washed-out colors, or needs to match other clips. It's essential for fixing exposure issues from improper camera settings, compensating for difficult lighting conditions, creating consistent look across multiple clips, or achieving a specific artistic style. Color correction is typically done before more creative color grading.

Brightness adjusts overall lightness (-100 to +100, where negative darkens and positive lightens). Contrast controls the difference between light and dark areas (0.5 to 2.0, where 1.0 is normal). Saturation adjusts color intensity (0 removes all color for grayscale, 1.0 is normal, values above 1.0 increase vividness). Gamma adjusts mid-tone brightness without affecting pure blacks or whites (0.5 darkens, 1.0 is normal, 2.0 lightens mid-tones).

This tool uses HTML5 Canvas API with CSS filters to apply color adjustments in real-time. When you upload a video, it extracts frames and applies your chosen brightness, contrast, saturation, and gamma values using canvas rendering. The preview shows immediate results, and when you download, it processes the entire video with your settings. All processing happens locally in your browser using JavaScript and Web APIs - no server upload required.

Brightness shifts all tonal values equally, making the entire image lighter or darker including pure blacks and whites. Gamma affects primarily mid-tones, adjusting the curve between shadows and highlights without changing absolute black or white points. Use brightness for overall exposure correction and gamma for fine-tuning mid-tone detail. Lowering gamma can recover detail in overexposed highlights, while raising it can bring out shadow detail.

Yes, you can improve low-light footage by increasing brightness and adjusting gamma to recover shadow detail. However, extreme corrections may introduce noise or grain that was hidden in dark areas. For best results, combine moderate brightness increases (+20 to +40) with gamma adjustments (1.2 to 1.5) and slight contrast boosts (1.1 to 1.3). Very underexposed footage will have limited correction potential due to lack of captured image data.

Yes, your video never leaves your device. This tool processes everything locally in your browser using client-side JavaScript. No video data is uploaded to any server, transmitted over the internet, or stored anywhere except temporarily in your browser's memory while you work. Once you close the page, all data is automatically cleared. This makes it completely private and secure for sensitive or confidential video content.

The tool supports common web-compatible video formats including MP4 (H.264/H.265), WebM (VP8/VP9), and OGV (Theora). MP4 with H.264 codec is most universally supported across browsers. Support depends on your browser's native video codec capabilities. If your video doesn't load, try converting it to MP4/H.264 format first. Most modern browsers support MP4, making it the recommended format for best compatibility.

Start with subtle adjustments and make changes incrementally. Use brightness and gamma to fix exposure first, then adjust contrast to add depth, and finally tweak saturation if colors appear dull or oversaturated. Avoid extreme values - natural corrections typically use brightness (-20 to +20), contrast (0.9 to 1.3), saturation (0.8 to 1.3), and gamma (0.8 to 1.3). Always check skin tones and neutral colors to ensure they look realistic.

While this tool doesn't save presets, you can manually note down the values you use (brightness, contrast, saturation, gamma) and reapply them to similar footage. For batch processing multiple videos with identical settings, record your final values and input them for each video. Footage shot under similar lighting conditions will generally benefit from the same correction parameters, making it easy to maintain consistency across multiple clips.
