You may not have noticed, but PowerPoint allows you to record your presentation. This can include recording yourself through the camera, recording your voice with a microphone, and recording notes right on the slide with a laser pointer, highlighter, and pen.
Voice recording is easy and allows you to present your information without having to write it all down on the slide for viewers that will not watch you present live. That is useful for listening to yourself present or for distributing the presentation online like Canvas. Voice recording
You can record using Camtasia or the built-in PowerPoint record function. To use Camtasia, finish creating your PowerPoint presentation then click the Add-Ins tab at the top. Next, select whether you will record with a microphone, webcam, or view camera options, record options, or access help. Most laptops have built-in microphones, but if you don’t have a microphone, you will need to get one or use headphones or webcam with a built-in microphone.
To use the built-in PowerPoint function, you will need to go to the Insert tab, then select Audio, Video, or Screen Recording.
Make sure you confirm recording with any application or device you are using. Camtasia uses a popup window to begin and end recording. If your recording does not work, try checking that the camera or record options are set to your preferences.
