In this lesson, one concept at a time, you will start editing video footage. You will use Keynote and ScreenFlowto insert a video into the larger YouTube video. This will be accompanied by moving text.
To make this exercise a bit more challenging, you will download video footage from three YouTube videos and edit them to make a single 21 second video. Then you will insert that into a Keynote slide. Let’s get started.
audio video lesson. Then return to this page.)
Click on the camera icon.
Watch the YouTube video below.
Watch the 3-second video. Note that some YouTube video footage is choppy before it gets fully downloaded. So, you may have to download it several times before you get really smooth action. (In case you are wondering, that video was created with Adobe Flash.)
Then watch these 3 examples of YouTube video footage.
Stop the ScreenFlow recording.
Save with a descriptive name.
Edit the video footage from point #3 above and save it in your clipboard (Cmd C). Click File > New Empty Document. Paste your video footage there (Cmd V) and save it with the descriptive name UploadOldMan.
In order to make sure your video footage is at least 3 seconds long, you may have to take your scrubber to the beginning of the video footage and add a freeze frame.
If your ScreenFlow clips are too tiny to work with, you may have to stretch them with the slider in the lower left-hand corner of the screen.
After your ScreenFlow clips have all been edited, Click File > Export to export your video as an MP4 file. Save it to the desktop as UploadOldMan.mp4.
One of the first things you will notice about your laser machine video footage is that it is narrow and high. So, you will end up inserting a narrow and high MP4 video into Keynote.
To get an idea of what the ratio really is, give it an initial aspect ratio of 1280 to 720. Then drag the slider so that the video is the correct height. You will be able to tell that it is about 3 times as long as it should be.
So, you click the aspect ratio icon again and change the length to around one third of 1280. Keep changing the length until you video footage is the ideal size.
Decide in which order the video footage was recorded.
Split clips, choose the best ones, arrange them in an order you like and create a 21 second video.
Save it as LaserEtchingMachine and then export it as LaserEtchingMachine.mp4 to the desktop.
