Hi this is Gary with MacMost.com.
Today let's look at a new feature in Keynote that allows you to play video and audio across
slides.

So Keynote version 10.1 has a new feature that allows you to place a video and audio
on slides like before but if the same video or audio exists on the next slide you can
choose to have the video or audio continue to play from one slide to the next.
So this is a feature in 10.1 so make sure you update to the latest version.
As an example here I've placed a video on this slide.
Typically if I were to create a new slide here I would just have that video on the one
slide.
So I could play that video on the one slide and continue to the next slide without the
video.
But now if I were to select this I'd copy it and paste it onto the next slide.
So the video would exist in both places.
Now when I select the video, under Format, Movie, I can choose the option of Play movie
across slides.
So let's put some things on the slides so we can tell them apart.
So now we have two different slides here.
Let's play this.
I'm going to use another new feature in Keynote and that's the ability to play but in the
window.
So it's not going to take over the screen.
Now here I could see Slide 1.
I'll click on the video to start it and there are the waves crashing down.
If I go to the next slide by clicking you could see the video is uninterrupted but I've
advanced to the next slide.
So you can use this to have a series of slides while the same video plays.
You could also set the slides to advance automatically, not on a click.
The way to you do that, of course, is you select the slide.
Go to Animate and Transitions and you start the transition to the next slide automatically
after a delay of a certain number of seconds.
Here's another example.
This has a video of me talking about something.
Then I've got three slides after that with some captions underneath.
So I want the video to keep going for each of these slides.
I'm going to select the video and then I'm going to go to Format, Movie and make sure
Play movie across slides is checked.
Then I'm also going to uncheck Start movie on click.
I want it to start automatically.
The next thing I'm going to do is Copy the video and then Paste it on each of these slides.
Now I could just play this here and advance the slides manually when it gets to the right
point.
But I could also have it do it automatically.
So I happen to know that the first caption should appear after 3 seconds.
So what I can do here is under Animate, Transitions for the slide I could say start transmission
automatically after 3 seconds.
On the next slide I could say start it automatically after 2 seconds which is when I get to the
next point.
Then on this slide go automatically to the next one after 3 seconds.
I simply got these timings by watching the video in QuickTime player and noting where
each point was that I wanted and jotting them down.
When I play this it will advance to the next slide at the right point.
(Video playing).
So you can see how handy that could be.
You could actually put together videos, kind of like the ones I do, by recording yourself
talking, putting this video down in a corner or something and building a series of slides
to travel through while that video plays.
You could even change the position of the video.
So, for instance, I could you know position it here, here, and here and it will work when
I try it.
(Video playing).
Now, of course, I didn't place them anywhere specific.
But you could imagine actually moving the video to a different corner of the screen
to just make it visually interesting as you advance through the points that you're talking
about.
You could even use a video as a background.
I can stretch this video.
It actually is full resolution here.
I can do it here on this slide as well.
Then have it advance automatically after a few seconds to the next slide.
Now it works as a background when I play it.
(Video playing)
Now you can do this with audio as well.
Here's an example where you may use that.
Say you've got some slides at the beginning of your presentation.
So you have this introduction one here.
You want that to be on the screen for maybe 5 minutes.
Then it will go to this one and be there for 1 minute.
Then this one and remain there until you click or press the spacebar to start the real presentation
on slide four.
It would be nice to have music playing across all three of these.
But only these three slides and not as background music through your entire presentation.
I could drag and drop an MP3 file here to this slide.
It appears here.
I'll set it up under Format, Audio to Start audio automatically.
So not wait.
I'll have it Repeat.
So Loop.
I'll have it play across the slides.
But what I'll do here is I'll take this.
I'll copy it and paste it into these slides here.
Now instead of five minutes and one minute I just set these each to 3 seconds.
I can demonstrate what goes on.
(Audio playing).
Now it will sit on this slide until I click and then it will go to slide four.
So with those examples I'm kind of just scratching the surface with what we can do now because
we can probably come up with other creative things to do when playing video and audio
across a series of slides instead of just only on one slide or in the case of audio
having it play across the entire presentation.
