Tips and Tricks on How to Edit Youtube Videos on Screencast-O-Matic

Do you have some video content that you want to share on YouTube? The most important part of post-production is editing, whether you’re making a video for family, friends, or your YouTube channel.

YouTube has a built-in video editor that lets you do basic things like trim, cut, add music, and blur the video. But if you want to make high-quality videos with titles, effects, and other things that keep people interested, you’ll need a more powerful video editor.

How To Use Screencast-O-Matic To Edit Youtube Videos


Many free software options exist for editing and converting YouTube videos, but some are better for new creators than others. Most free online video editors for YouTube require you to sign up for an account. Many put a watermark on your video, which could be better if you edit it for YouTube.

Screencast-O-Matic is an easy-to-use YouTube video editor that does not add a watermark to your video or require an account to edit.

1- Open the free video editor

Visit the Screencast-O-Matic website to use the free video editor.

2- Upload your video

Click “Choose Video to Edit” and find the videos you want to change on your computer. You can change video files that are MP4, MOV, or web-m. If you want to combine multiple video clips, upload the first one. You can always add more clips in the editor.

Next, click edit video, under recent videos to start. Users who have never used the app before will be asked to download and open it.

3- Set the size of your YouTube video

On the right side of the editor, you’ll see options to change the size of your video canvas or the ratio of its width to its height. Click “Resize” and pick a canvas size from the list or make your own. The 1080p and 720p presets are the best sizes for YouTube videos, with a 16:9 aspect ratio.

4- Trim your video and cut it up

The first step in editing videos for YouTube is to trim your video and cut out any parts you don’t want in the final video.

  • Select “Cut” from the “Tools” menu.
  • Move the red bar along the video’s timeline to choose the part to cut.
  • Or, you can click the beginning or end of the video clip and then use the arrow keys to move back and forth to find the part you want to cut. You can preview your video to see how it will look with the selected area cut out, then click “OK” or press Enter to miss your video.
  • You’ll see a dashed red line where you cut your video on your timeline. If you decide to undo the cut later, you can do so by clicking on the line, the red scissors icon, and then “Remove.”

5- Cut, resize or style your video

You can crop your video, zoom in or out to change its size, or add a background color or some simple effects to make it look better.

  • Click “Main Video” to access the video editor’s global editing tools.
  • You can crop your video by clicking “Crop” or zoom in or out by clicking “Resize.”
  • Click “Style” to change the shape of your video or add a shadow to it. You can also change the color of the background of your video canvas. To move your video to a different part of the canvas, click and drag it. It’s easy to add images and other videos as overlays, and you can also change the size and style of these overlays.

These simple video edits are great for the tutorial, instructional, webinars, and other educational videos you want to put on YouTube.
