You may shoot a video to capture a particularly important moment but the lighting isn't exactly what it could be, thus result in a muddy, low-contrast video that is difficult to see. To help you preserve an important memory and avoid disappointing results, Wondershare Filmora9 (Latest Filmora version 9) is a good helper. Just follow some simple steps below to easily increase the brightness of video.
1. Import the video you want to increase brightness
After running Wondershare Filmora9, click the 'Import' button and the import media item window will open and display the files on your hard drive.

2. Increase brightness of video
Double click the video in the Timeline and then you will see the editing interface which you can switch between Video, Audio (if it has), Color and Motion tabs. In the Video tab, you can change the clip transform with the Rotate, Flip, Scale and Position Settings. Switch to the Color tab, you will find the White Balance, Tone and 3D LUT options.
To increase brightness of the video, go to Tone option and drag the Brightness slider to right to increase. To preview the real-time result, just click the spacebar to play the video. You will see the video appear brighter because of your operation. If the video is still too dark, repeat the previous step. Each time you increase brightness and contrast of the video, it will get brighter.
Besides adjusting Brightness of video, you can also use Filmora9 to adjust Contrast, Saturation, Hue, Saturation, Tint and Temperature, appy 3D LUT effects from Hollywood movies to videos with ease. You can also do some advanced color correction in the Advance Color Correction window.
