By Cecilia Hwung | Last Update:

How to brighten a dark video on iPhone? At the mere mention of the iPhone video brightening idea, the first response for most people may be: do it with a video editing app on iPhone. However, unlike the Photos app, many third-party apps or even  iMovie cannot brighten a dark iPhone directly, and they would use filters and special effects to do the work instead, which might be a little farfetched. Thus, it is not a common solution for everyone in every situation.

But is there any workaround? Well, here in this post, we have laid out the top 4 ways that you can dig in to brighten a dark video on iPhone and make a dark iPhone video brighter on PC/Mac. In addition, we have illustrated the respective pros and cons of each solution so that you can find the most proper way to polish up your dark HD/4K dark videos that are shot in low light without a hitch.

Plan Ahead: How to Brighten a Dark iPhone Video When Recording

If you can get thing right in pre-production, why leave it to post-production? Focus and exposure values are at the heart of brightening a video properly. There is no 1-tap magic to bring up the luminance value of your video, because when you change it, the brighter part will be overexposed. Follow these steps to properly brighten an iPhone video before or while recording:

Step 2. Tap on that sun icon and swipe it up and down to adjust the brightness. If it is not ideal, you can tap on the screen again to slightly change the focus point, and re-adjust the exposure level.

Step 3. If you want the video to have a same brightness level the entire time, go firmly press on the box, and you shall see an AE/AF LOCK on top of the screen. It will ensure that the camera will not automatically adjust focus point and exposure.

Bonus Tips: If you are shooting an iPhone video in an environment with constant light changing, or you want to combine several iPhone videos together, but find out that the clips have different brightness level, you will need professional color grading software to balance out the footage.
