LumaTune

Tune video brightness, color, and speed from the popup or directly over the video.

LumaTune helps you adjust how videos look and play directly in your browser. Use the Tune tab to quickly control brightness, contrast, saturation, and playback speed up to 8x. Each control includes a precise numeric input, real-time updates, and an individual reset button. The compact on-video panel follows the most relevant video and provides the current speed, speed steps, quick choices, temporary disable, and reset without repeatedly opening the extension popup. It works with dynamic media and compatible embedded players after optional access is enabled. LumaTune Pro unlocks advanced visual tools, including gamma, sharpness, RGB color balance, custom presets, and the ability to apply adjustments to videos, images, or the whole page.
