Set up the initial slide format

- Go to the View tab.
- Click Slide master.
- Click on the top most slide on the left hand panel
- Then click on Slide Size on the ribbon.
- Click Custom slide size and change the height and width.
Create and Animate

- To animate elements
- Go to Animations tab.
- Select item.
- Click on the type of animation.
- Tune the effect options and timing. Showing the Animation Pane may help if you have anything complicated.

- Go to the Slideshow tab
- Click Screen recording
- The presentation may get minimised and replaced by a recording toolbar. Re-maximise the presentation (the recording toolbar will stay visible on top).
- Using the select area tool from the Recording toolbar, select the slide outline so that its highlighted by a red dashed rectangle.
- Navigate back to the Animations tab on the ribbon.
- Click the Record button on the Recording toolbar.
- A 3 second countdown timer will start
- Once the recording starts, click the Animation preview button (top left)
- Stop the recording (by pressing the Square in the Recording toolbar) when the animation is complete.
- A video of the animation will be inserted into the slide.
- Right click on that video and click "save media" save the mp4 file
Converting the file
- Go to https://cloudconvert.com/mp4-to-gif and upload the mp4 for conversion to gif.
- Click the spanner icon to change the default settings.
- Use a custom resolution of 240 x 64
- A video codec of GIF
- A frame rate of 15FPS.
- You can also trim the start or end if needed, e.g. if you were a little slow with triggering the animation or stopping the recording.
- Click convert.
- Download the resulting file
NOTE: The exact process may vary slightly with different versions of PowerPoint, but the functionality should still be available with any relatively modern version. Instructions here are specifically for PowerPoint 2013.
