Update: In November 2023, Google announced a native video slide narration capability.
The process below can still be used if you need video editing capabilities.
There are times you may want to record a voiceover on top of a Google Slides presentation.
Your Slides voiceover may be for internal sharing within your organization. Or, your recording may be for sharing publically on YouTube.
An easy way to record a voiceover on Google Slides is with Camtasia from TechSmith. Techsmith publishes both Windows and Mac versions. You can try Camtasia free for 30 days.
Camtasia allows you to record a custom region on a screen. This means you can record your voiceover directly from Google Slides edit mode, which is easier than trying to do a full-screen recording.
Here are the steps:
1. Click the red Record button in Camtasia.
