David Cox: There are several different ways that you can create a slideshow
on your Mac using nothing more than the tools that come with it.
The best method for you depends on what type of audience you're cater
to, as well as how much time and effort you wanna put into making it.
There are basically two types of slideshow audiences: active and passive.
With an active audience, everyone is sitting in front of a screen
watching simultaneously, and no one is talking to each other while it plays.
If that's the type of slideshow that you want to create,
that's great, but this is not the video for you.
The type of slideshow that I'm going to teach you how to create is perfect for
passive audience situations, meaning that this slideshow is going to be
played on a monitor in the background.
This is perfect for large gatherings like weddings, fundraisers, dinner parties,
reunions, business conferences, etc.
My favorite way to create a slideshow coming up next on Tech Talk America.
Hey folks, and welcome to the class.
The type of slideshow that I'm going to teach you how to create is
referred to as a virtual photo wall.
Here is a preview of what the final product will look like.
As you can see here is added virtual frames around each of my images,
and it places them on a wall.
The photos move slowly across the screen, so there is plenty
of time to view each image.
Before we create the slideshow, we first need to gather all of
our photos together and bring them into an album using the Photos app.
For this example, I'm going to be creating a photo wall of my best drone photos,
So I'm going to hold down the command key on my keyboard and select a bunch of
those images in case you didn't know it.
The shortcut to create a new album from what you have selected is Command N.
If you want to add photos to your album after creating it, just drag
and drop them into that album.
So here's the funny thing.
That photo wall effect is technically a screensaver.
There's just one little problem.
You can't export a screensaver as a video file.
That is, unless you do this.
Let's start by closing the Photos app, and now I want you to go to
the Apple icon at the top left and go into system preferences.
If you're on a desktop, I want you to click on Energy Saver Settings, or if
you're on a laptop, go into Battery and then click on power Adapter.
By the way, if you are doing this on a laptop, you should probably plug into
a power source for this next step.
For the time being, I want you to disable this feature, which turns
your display off after a period of.
At this point, let's click the show all button here at the top
to go back to system preferences.
And now I want you to go into desktop and screensavers.
Then click on the screensavers tab.
We don't want our screen recording to be interrupted by the actual screensaver.
So for the time being, let's turn off the screensaver.
Then let's click on the photo wall effect.
Let's now change the source to photo library, and then click into albums and
select the album that you just created.
In a moment, we're going to set up your Mac to record your screen for however
long you want your slideshow to run.
Now before we proceed, I want to give you an expectation about
how big this file is going to be.
Full screen video recordings tend to run around one gigabyte per
minute, but depending on your setup, it can be more or less.
I bring this up because if you are running low on disc space, you might want to
save this file to something like a flash.
Let's get the screen recording ready on your keyboard, I want
you to press command shift five.
Now, I want you to click this button on the toolbar, which will
allow you to record the entire.
Next, let's click on options and tell it where we want this file to be saved.
In my case, I have plenty of storage space, so I'm going
to save it to my desktop.
At this point, we're good to go.
So let's click capture and then immediately click
here where it says preview.
Now just let it play for however long you want the video to be.
When you're ready to end the recording, just move your mouse, which will stop
the preview, and then click the stop button here at the top right of the.
You'll see a preview of the file appear at the very bottom, and after
a moment it disappears off to the.
As you can see, that file is now here on my desktop, and the first thing that I
want you to do is to rename this file.
You'll see why in a moment I'm going to call this drone slideshow.
The last thing we need to do is to edit out the first few seconds of the
beginning as well as the end of the video.
So let's double click on the file to open it up in QuickTime.
And now you can press command T on your keyboard to go into trim.
I'm now going to grab this bar on the left hand side and drag
it to the right just a little bit until I get to the black screen.
That looks good.
Now I'll do the same thing at the end of the video so that I can cut out the
part where I end the screen recording.
Now that everything looks good, I'll click Trim to make those edits.
The last thing that we need to do is to save this file, so let's go to file and
click save To Prevent from duplicating the file, just type in the exact
same name that you gave it a moment.
When you go to click save, you'll get this dialogue box confirming
that you're replacing the unedited version with the edited version, and
now click replace When you're done.
Don't forget to go back into system preferences and reenable your energy
saver as well as your screen saver.
