Why Black Bars Appear?
Have you ever experienced this: after hours of editing, you finally upload a video, only to be surprised to see frustrating black bars on both sides of the screen when you play it?
You’re not alone. These black bars, also known as letterboxing, are black areas on the top, bottom, or sides of a video, and they can appear when the video’s aspect ratio doesn’t match the screen’s aspect ratio.
There’s no doubt that in most cases, black bars will make your video look unprofessional and ruin the immersive viewing experience. Therefore, you need to remove these bars to provide a better viewing experience for your viewers.
In the following content, you’ll learn how to remove black bars from video online with Clipchamp and CapCut online video editors.
How to Remove Black Bars from Video Online No Watermark
Before learning the specific methods to remove black bars, let’s quickly review the common aspect ratios and application scenarios.
Common Aspect Ratios
- 16:9: modern standard for YouTube, Vimeo, widescreen TVs, and most computer monitors.
- 9:16: mainly used for smartphone videos, such as Instagram and Facebook Stories/Reels, TikTok videos, YouTube Shorts, Snapchat Snaps, Stories, and ads, etc.
- 4:3: the standard for older televisions and film. You can now select this ratio for your video to create a vintage feel.
- 1:1: a perfect square format, mainly used in Instagram posts.
Generally speaking, there are 2 strategies to remove black bars from video:
- Cropping: the most common solution and best for videos where the main subject is in the center.
- Zooming: directly enlarge the entire video frame until the black bars disappear from view. However, this can make the video look blurry.
- Add background fill: Replace those black bars with a colored, gradient, or blurred version of your video.
