The following describes how to create an animated gif from a series of PowerPoint slides in PowerPoint 2003, 2007, 2010 in Windows. It requires you have GIMP installed.

PowerPoint

1. Open the powerpoint presentation.
2. Select "File" -> "Save As" (File being the large round office button)
3. Either click on "Save As" or click on "Other Formats"
4. Select where to save (this will save as a folder of images)
5. Under "Save type as", select "GIF" and click Save

GIMP

1. Open GIMP
2. Select "File"->"Open As Layers"
3. Navigate to the folder of images with down "Ctrl" and click to select several files, or click on a file and then hold "shift" and click on one further below to select those in between.
4. Select "Open"...Gimp will now load the images.
5. Select "File" -> "Export As"
6. For the "Name", make sure it ends in ".gif" such as "example.gif" and click save
7. An Export File Dialog will pop up:
8. Another dialog will pop up:

Specify if you want to loop forever, the delay between frames (1000 ms = 1 second), click use delay entered above for all frames, and do "one frame per layer".

9. Hit Save and you're done.

PowerPoint resolution

You may need to adjust PowerPoint's resolution. Currently, this can only be done via the registry or an addon. You may adjust the image size in GIMP, but doing so is more lossy (less clear image). The following script will automate the change of the image resolution.

Instructions

1. Open a plain text editor, such as notepad
2. Copy and paste the code below into notepad
3. In notepad, select File->Save as and select "All files" at "File Save as Type"
4. Right click on PowerPoint.vbs in the directory and select "Open with command prompt". It should run. You should get a command prompt window (a black window) with output.
5. It will ask you what to set the resolution to.
