How to remove BLACK BARS from video (Screen recording tips)

In this tutorial I'll show you how to remove black bars from your videos when recording your screen using tools like Camtasia, ScreenFlow, OBS, or Screen-O-Matic.

WINDOW RESIZING BROWSER EXTENSIONS

EXPLANATION:
Black bars appear when the recorded video doesn't match the proportions of the video player used to reproduce it.
The most common video formats have a 16 by 9 aspect ratio, so if your recorded screen area doesn't match that aspect ratio, you will get the unsightly black bars.
Standard 16:9 high definition formats are 1280 by 720 (720p), 1920 by 1080 (1080p), and 3640 by 2160 (4K).
In this short tutorial, you'll learn a nifty trick to avoid those pesky black bars once and for all.

Peace, Love, Cookies.

Thanks for this! Do you know how to avoid the black bars of death when using an iphone to record on a zoom meeting? The meeting is 16x9 but my iphone records in 4x3 and I get the black bars whenever my iphone is the speaker. Is there a solution for this? Thanks!

Problem is that i dont have a computer, is it possible to do it with a phone?

Do you know how to post process a zoom recording that has the speakers side-by-side so that each speaker is in a square window next to each other on a single 16:9 screen? I want to take some recordings where I was doing interviews and we were side-by-side and eliminate the black bars at the top and bottom, but to do this seems to require way to isolate the left and right images and then combine them into a single output stream. Thanks!
