Definitions and resources for terms and techniques used in the world of presentations
When your PowerPoint presentation is digitally signed and shared, it helps to validate your identity. At times, you may want to remove a digital signature attached to your PowerPoint presentation. Why? Maybe you want it signed by someone else, you may want to use another signature, or maybe there’s no need for a particular presentation to be signed anymore. Follow these steps to remove the digital signature from a PowerPoint presentation in PowerPoint.
Once you add a sound track, such as a music clip, to your PowerPoint presentation, you can let the inserted audio span across all your slides from the first one to the last by selecting the Play Across Slides option. That’s great if you need the same music playing on all your slides. But what if you want the music to play only across some successive slides? What if you want the music to play from slide 1 to 12, and let all subsequent slides play without any music? Or you may want to add another audio clip for the next set of slides? Either way, it is possible to limit the number of slides that your music will play across.
After inserting an audio file, such as a background music file within your PowerPoint presentation, do you want to play this sound track across slides without any interruption when you move from one slide to another? Firstly, if a live speaker is spearheading the presentation, then you don’t want to add a sound that spans across slides. Why? Because then the sound will distract the audience, and also the speaker. However, if you are showing a sequence of slides that includes pictures and no live presenter is required to speak to the audience, then adding a sound across slides may be a great idea. Even then, a soothing background music score playing across your presentation slides can be a good fit. Stay away from loud or jarring tracks.
PowerPoint allows you to insert video and also online videos files within your presentation. One of the file formats that you can use for these video options is Flash SWF. However, these SWF clips may not play because of security settings. Fortunately, you can use the Developer tab of the Ribbon to insert Flash SWF movies.
Do you want to add a video clip to your PowerPoint slide so that it continues to play across subsequent slides? This means that when you move from one slide to another, the video continues playing without any interruption. In PowerPoint 2007, the Play Across Slides option was available within the interface. But in PowerPoint 2010 and later versions, this option is no longer available. However, there is a workaround to make a video play across slides.
After inserting a video clip into PowerPoint, you can play the clip with minute control over its volume, looping, rewinding, etc. Rather than create smaller tutorials that explore these options, we are exploring them all together. Before we do so, it’s important to understand that these abilities only exist so that you can use them when they are required, rather than using them just because they exist!
You have already explored what a digital signature is, and how a digital signature can be important for use in PowerPoint presentations. To digitally sign a presentation, you need a digital certificate. In these tutorials, we will explore how you can both acquire or create a digital signature using PowerPoint.
When you insert a video clip in PowerPoint, you may find that the inserted video starts playing abruptly when started within the Slide Show view, causing a jarring interruption to the flow of your slides. Fortunately, this is avoidable if you opt to add Fade In and Fade Out effects to the beginning and end of your video clip.
After adding Bookmarks to video clips, you may want to know how you can edit and remove those Bookmarks. PowerPoint does not let you edit inserted Bookmarks. For instance, you cannot change the time of the Bookmark from 25 seconds to 28 seconds. You will have to remove the Bookmark you wanted to edit and add a new Bookmark all over again! On the other hand, removing a Bookmark is easy!
When you insert a video clip within a PowerPoint slide, you’ll find it placed as a traditional rectangular shape. And that’s what most users expect, as it seems safe and conventional. However, PowerPoint allows you to have your video playing in different shapes such as a circle or oval, or a wave, a triangle, or any of the shapes that PowerPoint’s Shapes gallery includes. However, just the fact that a video can be placed within a shape is no reason to forego the conventional rectangle. Do remember that most other shapes may crop out important parts of your video clips.
