By Carrie Murray, Tuesday, May 14, 2019

A dark video taken in low light is difficult to view. You can fix that by adjusting the brightness of a dark video. Whether you need to brighten dark videos on Windows, Mac, Android or iPhone, there's always a method for you.

In this article, 3 convenient methods are introduced to increase video brightness while maintaining video quality as much as possible.

Brighten a video in Windows 10/8/7

To lighten a video in Windows 10/8/7, you can use PawEditor, a video editor that can quickly brighten dark video while ensuring high video quality. It can adjust the brightness, contrast, saturation of a video to make it brighter and clearer.

In addition, it can also trim videos, add subtitles, text, filters, transitions or special effects to make professional videos.


Step 1: Import a dark video

After installing and opening PawEditor on your computer, it will ask you to create a project or select a project on your PC. If you are using it for the first time, create a new project and name it.

Then import the dark videos by double-clicking the empty area in the video library.

Step 2: Light up the video

To make changes to a video in PawEditor, you need to add the video to a timeline track first.

Drag the dark video from the library to a track. Then you can brighten the video using the Brightness color effect.

Dark Videos

Select the dark video on the track, click the color tab, select Brightness and click the "+" icon to add the color effect. You can drag the brightness slider to light up the video. You can preview the brightened video in the Preview window.

Step 3: Export the brightened video

After the dark video is fixed, click Export Video Button to save the video locally. You can adjust the output preferences: name, path, resolution, frame rate, format, and more.

Brighten a video with iMovie on Mac

iMovie is very familiar to Mac users. It is a powerful video editor that provides color correction options to adjust shadow, brightness, contrast, saturation, the temperature of a video. Here is how to brighten dark videos with iMovie.

Step 1: Import a dark video to iMovie

Drag a video to the timeline of iMovie to begin editing.

Step 2: Adjust brightness in iMovie

From the menu bar on the top of the preview window, click Color Correction. There are three bars you can correct video colors.

In the first bar, select the slider of "Adjust Brightness to make the clip lighter or darker" and drag it to the right to make the video brighter.

Adjust Brightness

You also can select the "Adjust shadow" slider to light up the dark area in the video. Or adjust contrast, highlight, saturation, color temperature to further correct the video.

Step 3: Save the brightened video

Click Share > File to save the edited video as a new file. 

Brighten a dark video on Android/iPhone

You can use Instagram filters to brighten dark videos on Android or iPhone directly. The filters are available when uploading videos or in Instagram Stories. But instead of uploading the videos, after adjusting brightness with the filters, you can choose to save the original videos to your device.

Note: Even though you have clicked Save Original Photos option, adding a filter to your videos in Instagram will certainly cause quality reduction. To avoid that, you may import the dark videos from iPhone, Android to PC and edit them with PawEditor.

So how do we brighten dark videos on Instagram?

Method 1

Start an Instagram feed and then select a video from your Gallery or Camera Roll. Instagram will start previewing and allow you to apply filters to the selected video. Select a filter to light up your video. The filter Lark, which can increase exposure, is recommended. Tap the filter twice to adjust the strength of brightening.

Method 2

All the above are the three simplest ways to brighten dark videos on Window, Mac, Android, iPhone. Leave a comment below if you have any question.
