Hi. This is Karen McKee, the Scientist Videographer. And in this tutorial, I'm going to show
you how to create a video of a slide presentation in which your voice is recorded along with
a full-screen image of your slides.
First, you create your slideshow in PowerPoint or a similar application. And so I'm using
an example of a Powerpoint presentation that I prepared previously for a conference, and
I'm going to use that in this example. Then you need to get a screen capture software
program such as Quicktime, Screenflow or Camtasia Studio. And for this demonstration, I'll
be using Screenflow.
When you open the application, select file and new recording and you'll get a dialog
box that looks like this. And what you want to do is, well first of all it's going to
record your desktop from your color LCD.
And then if you want to record your own image as you are giving your presentation, you select
this first box, and it's going to open up the camera on your computer. And in my case,
it's the FaceTime HD Camera. Then if you want to record the audio from a different
microphone from than what is built in to your computer, then select the external microphone
that you prefer. And then you can see that I've got this hooked up to my external microphone,
and it's picking up my voice on that external microphone.
And then all you do is tap the record button and the recording, you will be given a 5 second
countdown, and then it will start recording. And now what you want to do is open up your
Powerpoint file and begin your slide show. And so now I'm in my slide show and what
I would be doing is talking about what is in my slide show and what I am presenting
during this presentation.
This is the title slide and this is the first slide of my presentation. The screen capture
will get, will record animations that appear on your screen as I'm showing here. And
as I go through my presentation, all of those screens and animations will be recorded along
with my voice explaining my presentation.
And then when you finish, all you do is tap "stop record", and the recording will
stop, and your file will automatically open up in Screenflow.
OK, so now we are in Screenflow, and what you see are two windows. The upper window
here is the viewer window, and you can see the file that was recorded. And in the lower
window, this is the timeline, and you can see the two recordings that were taken simultaneous.
The one on top here is the file that was recorded by the FaceTime HD camera on my computer,
and the second one is the recording of my computer screen.
And let's play a little bit of it so you can see what this looks like in the viewer
window. [playing the recording].
OK, so you can see what has happened here. The program has put the upper recording of
my image into a picture in picture window. And what you can do is you can resize this
window. Now to constrain the scale, you want to hold down your shift key when you are dragging
these corners, so that the proportions are retained. And so you can make that window
showing your image as large or as small as you wish. And that's going to depend on
your particular situation and preferences. So I'm going to leave it at about that size.
And so if we go forward..
[playing the recording]
You can see..you can see how your presentation is going to look and whether you even want
this window showing your image in here at all. Some people find this distracting to
have the speaker showing. You can also choose to show this at just at intervals or you can
switch back and forth between your computer screen and your presentation slide and the
image of yourself. Just depending on how you want to set this up.
OK, what you next want to do is to trim your footage in the timeline window so that it
cuts out any extraneous footage. And to do this you want to select both of these files
by holding down the shift key and tapping on both of them. Now what you can do you'll
see that when I move the cursor over, it changes and now what you want to do is..move the
playhead to the point in your presentation where your presentation actually starts. Because
this first part just shows your desktop, which you don't want to show.
So let's say you want to start your presentation right at the beginning at this point, and
so now what you want to do is trim your clip to that point. And you want to go down and
do this at the end of your presentation.. down here. And you want to cut out all that
stuff at the end. And so we'll find where the end of that presentation was and we'll
trim the other end of that clip. And then you can move this back to the beginning and
reposition your playhead and so now your presentation is going play from the beginning and you're
not going to have all of that extraneous footage.
Now the other thing you that can do, which is quite useful, is you can use the tools
over here to edit your footage. And, for example, let's look at the picture in picture window
here showing my image. What I can do is I can select the video option, the video properties.
I can scale that image here. I can change the opacity if I want to. I can change the
brightness if it's too dark or if it's too light. I can change the saturation.. and
whatever needs to be done to modify that image so that it appears the way you want it.. similarly
you can do some editing of the audio properties; you can do some editing of the screen recording
properties. You can add callouts. Now you can only do this actually to your screen recording.
You can add callouts, you can add annotations, you can add text boxes, and you can add additional
media such as music.
So once you have everything the way you want it, then you want to save your file and prepare
it for publishing. To do that, you go to file, and you see that you can publish it directly
to YouTube or Vimeo or other sites. or you can export it as a movie file. And here you
can select the export format depending on where it's going to end up...the web, iPad,
iPhone, whatever. I usually rescale mine to 100%. And then all you do is tap export, and
that file will be exported with a .mov file extension on it.
You can customize the settings. I usually export it as H.264. You want to make sure
the sound is selected, and for now I'm going to leave all of the settings on their default
position. And I'm going to export this. And now it's exporting.
Now that file is exported. Let's minimize that window. And here is the movie file over
here on my desktop. And we'll open it up. And here you can see that movie, and it will
play and all of the slides are there as well as my embedded image.
So this is a great way to create videos of your conference presentations or seminars
to post perhaps on your website or you might want to send them to someone. You can also
create lessons to augment a course you are teaching. You can record class lectures for
students to review your lectures as many times as they wish. There are lots of possibilities.
Virtually anything that you can show on your computer screen can be captured this way and
published as a video.
I hope you found this tutorial informative and that it has given you some ideas for creating
videos to show off your work. This is the Scientist Videographer. Thanks for watching.
