Media-rich presentations are great, but can result in a huge file size. This can cause problems when trying to share your presentation, or even cause PowerPoint to crash. But is there an answer? Absolutely. In this article we share five ways to compress PowerPoint file size for easy emailing and speedy running of your presentation.
You know when you’ve got a conference call and you’re first on, and there’s that blissful silence when you can contemplate anything in the world? What do you do? I found myself in that situation the other day, and I ended up being a bit like Darth Vader…
No, not like that. I wasn’t the heavy mouth breather on the conference call. I built a Death Star. In PowerPoint. Just because, you know, I could. And then I invented an ion drive to move at sub-light speeds around it. Pretty nifty. And it took how long? About two minutes. Let me show you how, using Bevels, 3D rotation, and the new Morph transition in PowerPoint 2016.
The content from the video can be found in the article below.
Let’s start on the spheroid, with a large concave dish in the northern hemisphere – or Death Star and superlaser emitter as you might know it. How would you do it – without getting a whole load of Geonosians and a Galactic Empire?
Start with a circle and then go to the Format tab on the ribbon, then the Shape Effects function. From there, choose Bevel and then 3-D Options, which will bring up the full 3D Format Options menu. This is where the construction begins.
Use the bevel, Luke
Let’s take a moment to understand the bevel function. If you imagine a shape in PowerPoint, like a circle, as a flat piece of paper laying on a table that you’re looking down on, the bevel function works on the shape in two ways. The top bevel provides height and form to the top of the shape – the part that you’re looking at. The bottom bevel provides depth and form to the other side of the shape – the part that’s resting on the table.
Then you need to understand what the bevel options mean. If you choose the standard round bevel for example, you can see that the shape gets a bit of a 3D edge to it. It’s now like a cookie, rather than a piece of paper, with a bit of height and rounded edges that curve to the flat top. The height is how much the shape sticks out towards you, while the width determines how rounded the edges are, and how far the bevel gets stretched into the shape.
If you increase the width, the shiny edge created by the bevel function gets closer to the centre, and stretches as the curve becomes flatter. If you increase the height it becomes more defined again, as the shape gets taller.
To make it easier to see and understand, put things into 3D using some 3D rotation. In the Shape Effects menu, under the 3D Format options open up the 3D Rotation options, go to presets, and choose the Perspective: Relaxed option. This spins the shape around and you can more easily see the height and the curve of the shape. If you increase the height on the 3D Format options you see the shape getting taller, and if you increase the width, you see it getting rounder.
If you’re keen eyed, you’ll notice that the top of the shape is rounded, but it cuts off sharply at the bottom. That’s where the bottom bevel comes in. If you do the same using the bottom bevel, clicking on the options to choose a round bevel, and then increase the height and the width, you see how the shape starts to fill out underneath now as well. So that’s how the 3D format options and bevels work.
The bevel is strong with this one
Our spheroidal Death Star needs to closely resemble a ball. This requires a careful balancing and matching of the height and width of the bevels you use, and typically, I find that they should be similar numbers. If you create a circle, put a round bevel effect on it and increase the height to maybe 100 and the width to the same, you start to get a nice hemisphere on the top. The actual numbers you use for height and width will vary, depending on the size of your original circle. Larger circles need larger numbers, so try a few to see which gets closest. Once you have a nicely rounded top, do the same to the bottom to get your basic sphere. Marvelous.
But what about the large concave dish in the northern hemisphere for the superlaser emitter? It wouldn’t be any use without that.
This is where you need to think about the type of bevel you need. If you look back at the bevel options, you’ll see that there are several choices. We’ve used the basic round bevel shape so far, but the next one along in the list – beguilingly called relaxed inset – gives you a different profile. Rather than being rounded and smooth, this one is rounded at the edges and then dips into the middle. This has some promise and is a feature that all leading mega death laser designers look for.
If you choose the relaxed inset bevel, it doesn’t look quite right initially. The dish will probably be far too large, which as you well know would lead to a diffuse laser that is difficult to focus. So adjusting the width of the bevel to bring in the curve is needed, which in turn reduces the diameter of the dip. And when you bring it in just enough, you end with the perfect dimensions.
The final thing to create the Death Star like appearance is the skin of it. This is achieved using a texture flood fill effect. Go to the fill options and select texture, where you’ll find a whole load of choices that I’d never recommend you use. But amongst them, the newsprint option in the middle gives, at a distance, a rough approximation of the pattern on the Death Star. Ta dah! Or should I say, Ta DAH DAH DAH, DAH DAH DAH DAH DAH DAH! [imagine to the tune of the Imperial March theme].
It’s a Morph!
Now, what about that cool trick where you get to fly around it and view your new creation? That’s achieved using the Morph transition, which, sadly for many, is only available in PowerPoint 2016, and even then, not the early versions of 2016, so make sure that you’re up to date in your Office 365 account.
Morph works across two slides and recognizes any objects that are on both and seamlessly transitions from one slide to the next. If you reposition the object on the second slide, during the morph transition, the object will move. Change the colour and it will blend to that new colour. You can even change the shape and size of an object. And amazingly, if you change the 3D rotation of the object, it will spin the object around to the new orientation, which is pretty funky.
To enhance the effect, put an image of a starry sky in the background and then copy it onto the second slide. There, you should resize it and reposition it, so that during the transition you get a nice parallax effect with the Death Star in the foreground and the stars in the background moving independently of each other.
And there you have it, your very own mobile, planet-destroying superweapon. Please, use it carefully and don’t leave the plans lying around.Leave a comment

By applying some key principles of presentation design, you can make your PowerPoint design really standout and deliver both a more ‘popping’, but also more effective presentation.
PowerPoint maps are great tools to tell visual stories – showing locations around the world and how they might all connect, global route maps for travel or logistics and different options, or really anything in the universe that you can show on some kind of map. What’s really neat, is that Office 365 has maps for PowerPoint built-in. Read on to find out everything you need to know about to make the most of this functionality in your presentations.
We were notified on Friday that we’ve been successful in our renewal bid. They were particularly complementary about our presentation and claimed it was one of the best they’ve had.Greg Tufnall Siemens
