Streamlabs OBS (SLOBS) is a popular streaming software, but resizing movie clips can sometimes lead to unexpected darkening. This article explains why this happens and provides solutions to restore your videos' brightness.

Understanding the Issue: Why Resizing Darkens Movies in SLOBS

When you resize a video in SLOBS, the software often uses scaling filters to adjust the size. These filters, while necessary, can sometimes negatively impact the image quality. The most common effect is a decrease in brightness or contrast, resulting in a darker-looking video. This isn't a bug; it's a side effect of the scaling process. Different resizing methods handle brightness and color differently.

Factors Affecting Brightness After Resizing

Several factors contribute to the darkening effect:

• Scaling Algorithm: SLOBS uses various scaling algorithms (like bilinear, bicubic, lanczos). Each algorithm handles pixel interpolation differently. Some are better at preserving detail but can darken the image. Others prioritize speed over quality.

• Source Video Quality: A lower-quality source video is more susceptible to darkening after resizing. The already compressed video data suffers more information loss during scaling.

• Bitrate and Compression: If your source video has a low bitrate or aggressive compression, the scaling process will exacerbate the compression artifacts. This leads to noticeable darkening and loss of detail.

How to Fix the Darkened Movie After Resizing in SLOBS

Fortunately, there are several ways to combat this issue and regain the original brightness of your videos:

1. Experiment with Different Resizing Filters

SLOBS offers different resizing filters. Experimenting with different options might yield better results. Try these steps:

1. Add your movie source to SLOBS.
2. Right-click the video source.
3. Select "Transform" and then "Filters."
4. Add a "Resize" filter.
5. Experiment with different resampling filters (like Bicubic, Lanczos). Lanczos often offers a sharper result but can be computationally expensive. Bicubic is a good balance.

2. Adjust Brightness and Contrast Manually

If changing filters doesn't work, you can manually adjust the brightness and contrast of the resized video:

1. Add your movie source to SLOBS.
2. Right-click the video source.
3. Select "Transform" and then "Filters."
4. Add a "Color Correction" filter.
5. Adjust the brightness and contrast sliders until you achieve the desired look.

3. Use a Higher-Quality Source Video

Using a higher-quality video from the beginning is always ideal. This means opting for a higher resolution and bitrate source file. This reduces the strain on SLOBS during resizing.

4. Pre-Process Your Videos

Before importing them into SLOBS, consider pre-processing your videos in a video editing program like Adobe Premiere Pro, DaVinci Resolve, or even simpler tools like iMovie. Here, you can resize and adjust the video's color and brightness without the limitations of SLOBS's built-in filters. This often provides the best results.

5. Check Your SLOBS Settings

Ensure your SLOBS settings aren't contributing to the problem. Look for settings related to output resolution or scaling, and try adjusting them.

Conclusion: Achieving the Right Brightness for Your Streams

Resizing movies in SLOBS can sometimes result in a darker video, but the problem isn't insurmountable. By experimenting with different filters, manually adjusting brightness and contrast, or pre-processing your videos, you can restore the original vibrancy of your movie clips and maintain a high-quality stream. Remember to use a high-quality source video whenever possible. This simple troubleshooting can significantly improve your streaming experience.
