How to Convert a Video File to WebM Format on a Mac or PC and Preserve Transparency

In this tutorial, we will guide you through the process of converting a video file to WebM format with alpha transparency using the application Shutter Encoder. This could be to reduce the size of the file, or to make it compatible with your streaming software. Let’s get started!

Step 1

Download and install Shutter Encoder for PC or Mac from the developer’s website.

Step 2

Launch the Shutter Encoder app. To import the video file you want to convert, simply drag and drop the file into the Shutter Encoder window. Alternatively, you can click on “Browse” to locate the file on your machine.

Step 3

Shutter Encoder allows you to convert files to lots of different video formats, but for WebM you need to select VP9 under the “Choose Function” drop down menu.

Step 4

To ensure that the transparency is preserved you need to click on “Advanced Features” and then select “Enable alpha channel”. You can ignore this step if transparency is not required.

Step 5

Now that you’ve selected the VP9 conversion function and enabled alpha channel, you’re ready to start the conversion process. To convert the video to WebM format, click on “Start Function”.

Congratulations! You have successfully converted your video file to WebM format. Consider supporting the Shutter Encoder developer with a donation if you find the application useful.
