How to Increase or Decrease Brightness of Video in BLENDER
Film & Animation
Introduction
Editing videos shot in low-light conditions can be challenging, but with Blender’s video editing capabilities, you can enhance the brightness and contrast to improve the overall look of your footage. In this guide, we will walk you through the process of adjusting brightness and contrast in a sample video using Blender.
Step 1: Importing the Video
Start by importing the video you want to edit. To do this, open Blender and navigate to the video editing section. Click on the "Add" button, and then select "Movie" to import your sample video file. For this example, we will be working with a 31-second video that appears quite dark.
Step 2: Setting the Review Range
Before making any adjustments, it is crucial to set Blender’s review range to the entire video duration. By default, Blender plays videos at a slower rate, which may cause some alterations to the effects. To set the review range, follow these steps:
- Click on the "Render" tab.
- Select "View" and adjust the frame range settings to match your video duration.
Step 3: Modifying Brightness and Contrast
Next, to enhance the video, you need to access the modifiers. Here’s how:
- Click on the video clip in the timeline.
- Navigate to the "Modifiers" panel on the right side of the screen. If this panel is not visible, click on the 'n' key to toggle its visibility.
Once you have accessed the modifiers:
- Click on the down arrow and select "Add Modifier."
- Choose "Brightness/Contrast."
Step 4: Adjusting Brightness
To increase brightness, you will find a slider for adjusting the brightness levels. Move the slider to the right to increase brightness.
For our example:
- I set the brightness value to 20.
Although the change may appear subtle at first, it significantly improves the overall lighting of the video.
Step 5: Adjusting Contrast
After adjusting brightness, it's important to also adjust the contrast to enhance the video further:
- With the same modifier, locate the contrast slider.
- Move the slider to the right to increase contrast.
For this clip, I set the contrast value to 20, which provided a pleasing enhancement to the video.
Step 6: Previewing Changes
After making these adjustments, use the I button to toggle between the original and modified versions of the clip. This will allow you to see the drastic improvement in brightness and the overall visual appeal of the video.
You can watch the clip to see the effect of the adjustments. The difference is remarkable; what was once a dark video now appears vibrant and sunlit, resembling an afternoon setting.
Conclusion
By following these steps, you can easily adjust the brightness and contrast of your videos using Blender’s video editing workspace. These adjustments can help to enhance your video's visual quality and make it more engaging for viewers.
