Discover how to integrate and enhance video and audio to create a more engaging PowerPoint presentation. In this course, author Alicia Katz Pollock emphasizes the technical details necessary to make a multimedia presentation work: from working with appropriate file formats, to applying video styles, to reducing the file size of multimedia presentations for sharing.
It's a good idea to keep your multimedia focused on material that supports the specific point you're making and trim out extraneous material from the beginning or end. If your audio clip is too long but you don't want to trim it, which would physically delete the beginning and end material, or if you just want to skip to relevant content, you can also specify a start time for your clip. I'm on slide 3 on my presentation. Play the clip. And note what time you want the clip to start to play. (Female speaker: Hansel and Petal?) For example, when I play this audio clip, I want to cut out the sound of the cellophane, so I'll the play the sound and then pause it at the moment I want.
I'll even press my Back button to go back a quarter of a second. Make note of the approximate time here. Now, go to the Animations tab up on the ribbon and then open up the Animation Pane with this button here on the right. Here's my sound. It's going to take place after my bullet points. Click on the drop-down arrow to the right of the sound and choose Effect Options. By default the sound is set to start from the beginning, but you can also set it to pick up where it left off, if you'll be revisiting a long audio clip.
You can also specify a custom starting point. That's what we need here. I'll set it to start 3.21 seconds into the sound clip. There's no way to enter a specific stopping time, but you can change the behavior of the clip. By default, if I click on the slide during a presentation, it will move on to the next slide, which is why this is After Current Slide. Here I can also click on the dot in front of On click and when I click the slide, the audio would stop. The next click after that would move me on to the next slide.
There's also a setting here for playing your sound clip across slides, but we are going to explore that option in the later video. I'll put this back to After Current Slide and click OK. Now when I click Play on my Speaker icon, it still has the original starting point. But when I play my slideshow and I click directly on my speaker? (Female speaker: Hansel and Petal for years has been providing me?) The sound starts at my specified time signature. When you don't want to play an entire sound clip, but you don't want to trim it, the ability to specify a start time for audio gives you control over what part of your clip you do want to hear.
