If you ever uploaded a video to YouTube only to find it darker than expected, you’re not alone. Why are my YouTube videos dark, and how can I fix it? Let’s dive into the common reasons behind dark YouTube videos and actionable solutions to ensure your footage shines from MiniTool Video Converter.

Why Are My Videos Dark on YouTube

The following are some of the reasons for dark YouTube videos.

1. Poor Lighting Conditions During Recording

The most frequent reason behind dark videos is inadequate or poor lighting during recording. If you’re in low light or facing a bright source of light, the video might appear darker than it really is.

2. Incorrect Camera Settings

A narrow aperture reduces the amount of light hitting the sensor, leading to darker footage. Some cameras automatically lower ISO in bright environments to reduce noise—but this can overcompensate, making the video darker than intended.

3. Low Video Quality

YouTube automatically adjusts video quality based on your internet speed. Lower video quality might enhance pixelation and make videos appear darker.

4. Accidental Activation of Dark Theme

Why are my YouTube videos so dark? The last reason is the accidental activation of the dark theme. Dark Theme (or Dark Mode) converts YouTube’s interface to a black/dark-gray background. It deactivates pixels in dark areas, which can create an illusion that the entire screen – including videos – is darker.

2. Improve Lighting or Adjust the Camera Settings

If you want to re-record your video and make it become more lighter, firstly, you need to find a good place where the light hits the object directly.

In addition, even with decent lighting, incorrect camera settings can turn your video dark. Cameras have auto-exposure modes, but they don’t always get it right. Widen the aperture to let more light in. Don’t use too low an ISO to avoid noise, and don’t hesitate to raise it slightly in dim environments.

3. Improve Video Quality

Here’s how to improve video quality for a YouTube video.

1. Go to YouTube and log in to your account.

2. Play the dark video and click on Settings below the video.

3. Expand Quality and choose a high resolution.
