Prezi allows you to add up to three background images to your presentation that will appear as you zoom into your canvas. These 3D backgrounds can be a visually impressive way to reveal content and can allow you to make striking thematic changes in a single Prezi.
- [Instructor] Now that we've talked about how the Prezi canvas is a 3D space and how you can change the stacking order of objects, I'd like to show you a cool feature that really takes advantage of this space. For this exercise, I'll create a new Prezi, and this time I'm going to click Start Blank Prezi. I'm going to zoom out a bit. I'm going to get rid of this default frame here, so we have a completely blank canvas to start with. I'm also going to come up to the settings button here and set the ratio to 16:9 for the monitor I'm currently using. Now so far we've been mostly working with templates, and we've seen that each template usually has a background image.
Let's take a look at how to place our own background image. Going to come up here and click Customize, and this is where we can set our background image. I'll click Choose File, and in my Exercise Files folder, I'm going to go into 04_04_3D_backgrounds, and if you have access to the Exercise Files for this course, you can work along with me. Otherwise you can do this with your own images. And here I'm going to select the file Red_phone_booths_bg. All right and there it is. Zoom in a bit. Let's close this for a moment. Now when you're creating your own background images, keep in mind that they can be up to 3,000 pixels wide.
Bigger is definitely better, especially if you're going to be zooming in to the canvas, making the background image larger on the screen. All right, so this will act as the background for this Prezi. Actually, it's going to be one of three backgrounds for this Prezi. For this example, let's say I'm building a presentation for our fictitious chain of hotels called the Landon Hotel. In fact, let's take a moment to add some text. I'm going to make this title text, and I can add a background color to this. Although, you know, I kind of like these red phone booths here, so let me turn that off. I'm going to go back to the Customize panel, and I'm going to change this to the Inferno Theme.
Now it doesn't look like anything has changed because we're zoomed into our image, but you can see the background color here has turned green, but what I want to do here is select the text, and then add this background color, giving us this nice red, and I'm also going to make the text white against that. There we go. And I'll make that just a little bit larger. All right, I'll click the home button, which takes me into my text frame, so this will be the starting frame of my presentation. To make this the starting frame, I'm going to go to Edit Path and choose Add Current View, and you can see that adds that to my path navigation, and I'll click Edit Path again to leave that view.
All right, so maybe in this presentation, I'm going to walk through the various cities in which we have hotels, starting here in London. I'm going to zoom out a bit. So I'm going to add a bracket frame, and drag this up here above the phone booths. Make that a little bit larger, and let's zoom into that frame, and here I'll add some text. Make that a little bit larger. And I also have a photo that I want to add here, so I go to Insert Image. I'll select my file. In this case, I want the one called front_of_hotel_London.
Make that a little bit larger. Now that doesn't look very old, so let's make it a sepia tone photo, so I'm going to go to Effects, Effects again, and let's find the sepia effect, Apply that, and Save it. All right, so there's my frame for the London Hotel. Let's continue adding frames along this section of the wall here. Scroll out a bit, and again, I'll add a bracket frame. I'll make sure it's a little smaller than the London frame here. I'll zoom to it and again we'll add some text.
Move that up there, maybe just a little bit larger, and again I'll add a photo. This time I want the one called San francisco_cable_car. This is telling me it's too large. Again when you see this message, it's a good idea to hit resize image. And let's make that a little bit bigger. All right, now let's add one more. I'm going to zoom back out again to get my bearings. I'll add one more bracket frame right about here. Make sure that's even smaller still. We'll zoom to that frame, and I'll add some more text.
Once again we've got an image we can add. In this case we'll choose the lion statue. I'll make that a little bit larger. Let's move that probably to about there. All right, I'm going to click my Home button to zoom back out. So that's what we have so far, so now I have this presentation started where I'm going to be talking about the various hotels we have in cities around the world, but my background image for each location is still a London background. It would be much more visually interesting and cohesive if I could place more appropriate backgrounds for the other cities.
Now we've already seen that to place the main background, we just come over here to the customize panel and click choose file, but that only allows us to pick a single main background image. So this is where 3D backgrounds come into play. 3D backgrounds let you select up to two additional background images that will appear when you zoom into a certain level of your Prezi. Now like everything else with Prezi, there's no way to easily know what that zoom level is, so you'll have to do some experimenting to find the right level each time. Let me show you what I mean. To add 3D backgrounds, scroll down here and click Advanced.
Here in the Theme Wizard, click Edit next to 3D Background. And here's where you can upload up to two additional backgrounds. Notice it says here that these backgrounds will fade in as you zoom in on your Prezi. So I'll click upload, and I'll select the one called Golden_gate_dusk_bg, and once we upload that second background, the option to upload a third one becomes available. And this time, I'm going to choose Hong_Kong_skyscrapers. All right, and I'll click Done and Done again. Right now it doesn't look like anything has changed, but watch what happens if I start zooming in with my scroll wheel.
At a certain zoom level, the San Francisco background appears. Now right now I'm starting to get this "Can not zoom in more" message. We'll fix that in a moment. Let me zoom back out and find our content. Let's select the London frame. Now notice at this zoom level, we start to see the San Francisco background start to appear, so if I don't want that to appear, and I don't in this case, I need to make this first frame a little bit larger, and again this is a lot of guess work. We'll zoom into that frame again, and that looks about right. Next I'll zoom into the San Francisco frame, and there we're firmly into the San Francisco background, which is fine.
I'm going to zoom back out again just to check the relative size of these. It's looking okay. Now I'm going to go back to the Hong Kong frame. Again, I'm getting this can't zoom more message, but let's make this even smaller, and watch what happens. All right, there we go. All right, so even though I saw that cannot zoom more message, I was able to force the issue by making this frame a little bit smaller. Let's go back out again. Now I just might want to reposition some of these here on the screen.
Maybe like so. Now to make sure this is really working, let's go into present mode. And I'll use the right arrows on my keyboard to step through my presentation as it is so far. So we start with this overview here, go into The Landon Hotel. There's the first one, and I can sort of see the Golden Gate Bridge starting to appear here, so I'm going to have to adjust that. Go to the next one. That looks fine. And that looks fine as well. So as you can see, it's a good idea to test this to see if the zoom levels work when you're actually presenting. So I'll press escape and go back out.
Actually, and while I'm here, I'm going to go to Edit Path and add this current view and make sure that's my first frame right there. Click Edit Path again to leave, and I'm going to make the London frame here even larger just to make sure it works. So I could go to present again. Let's just go back here. All right, so that looks like it's working now. So we start here, we still see the London background. Here's San Francisco. And here's Hong Kong.
All right, so that's working with 3D backgrounds. This is a really cool feature, but as you just saw, it does take some experimenting to find where the zoom points are that cause the background to change. If you're going to work with 3D backgrounds, I suggest placing at least one frame at the right size for each background. That way you'll know approximately what size to make other frames that need to use that background. Also bare in mind that you don't have to start with the main background image and zoom in. You could start your presentation zoomed in all the way to the level of the third background and then work your way back out. So this can be a really cool and visually impressive way to reveal content, and it can allow you to make striking thematic changes in a single Prezi.
