This is a follow-up to the last post which was about using slide transitions in the role of on-slide animations. One technique I demonstrated was to create a separate file using the transition effect, convert it to a video, and insert it into the presentation.
This post will not make much sense unless you read the last one.
At the end of the post, I suggested that this doesn’t work very well for some transitions. For example, if I try to create a photo carousel effect using a Gallery transition, this is the result:
The black artifacts that appear are probably not desirable. About 11 of the available transitions in my version of PowerPoint have artifacts like this.
I also said that the size and shape of the slides in the presentation used to create the video can also have an effect. Here’s an example with a custom slide size:
Here’s how I did this one:
- I created a new presentation and inserted the contract image into the first (blank) slide.
- The image is about 7″x5.4″. I changed the slide size (Design/Slide Size/Custom…) to the same size plus an inch vertically. I’ll explain the extra inch later. Here’s what the slide looks like:
When you change the slide size, PowerPoint offers two options: Maximize and Ensure Fit. If you pick the first option, PowerPoint will basically leave your slide content alone. If you pick the second option, PowerPoint tries to scale objects on the slide to fit the new slide. This will often lead to distortions. I usually pick the first option and layout the slide manually. Thanks but no thanks.
- Next, I created the second blank slide and added a Crush transition.
- After a few adjustments , I converted the presentation to video and inserted the video in my original presentation. (See the original post for details). Here’s what the resulting slide looks like:
- I did not crop or resize the video frame. I did set it against the bottom margin of the slide so that the crushed contract appears to fall off the bottom of the slide (this is what the extra inch in the slide slide size is for).
Here’s another example announcing a new service:
This example uses the Curtain transition and shows how you can combine the re-sized video with an object (a simple proscenium) on the slide. In some ways, a video is just another PowerPoint object.
Here are some other useful things you can do with videos:
- Crop and resize the video frame
- Change the shape of the video frame
- Synchronize the video with other animations
- Edit (in a limited way) the video
Of course, you can do these things with any video, not just the ones you create. And there are other possibilities that I will explore in later posts.
Here’s an example
This example combines a video created with a Fracture transition with a simple Fly-in animation. Here are some details (again, refer to the previous post if you haven’t already):
- The PowerPoint file from which the video was made has a square (7.5in x 7.5in) format.
- The first slide contains the target image and the second contains the text.
- The first slide has no transition; the second has a Fracture transition with a 0.5 sec duration.
- The first slide is set to advance after 0:00 sec; the second advances on click.
- The file was exported as a video.
- I inserted the video into my presentation file, resized it to fit and changed the shape of the video to a circle.
- The black circle has a Fly In/From Lower Left animation with the Hide After Animation option.
- To get the timing right, I used video Trim to make sure that the video started at the time the Fracture effect started (there is a slight delay in the video – I’m not sure why).
- I also used Trim to eliminate the last 5 seconds of the video; here’s what the Trim pane looks like:
The extra 5 seconds in the original video is the default slide timing for the video conversion. This showed up because the last slide had Advance on Click set rather than a time – it was easier to fix this here than go back and re-make the video.
- I also overlapped the animation with the video to get the timing to look right; here’s the animation pane:
Here’s a similar experiment using the Ripple transition:
The details are similar to the Fracture example except that the Ripple effect has an unwanted “artifact” around the edges. I eliminated that by cropping the video a little more.
