brighten.video

brighten.video helps rescue clips that came out too dark, including evening scenes and backlit footage. Auto samples frames and applies a balanced correction using exposure, shadow lift, highlight protection and gentle noise reduction. Manual controls let you adjust exposure, shadows, black point and colour when a particular shot needs a different treatment. The footage is processed on your device in the browser, keeping the source media out of a cloud upload workflow. It is free, with no account or watermark.
