How to Convert a PowerPoint or Keynote file to Slides

PNG is the recommended export format for generating high-quality slide images for your presentation video. However, Presto can work with a wide range of image formats, including:

 

 

Converting from Microsoft PowerPoint

Renaming slide files using Windows Explorer

If a single presentation video is based on multiple presentations — for example, you have several PowerPoint or Keynote presentation files to work with — you may need to rename the slide image files that you export from PowerPoint or Keynote, because Presto requires that each slide image has a unique filename.

In Windows Explorer, it's easy to rename a group of slide image files. When you select multiple files in a folder, Windows automatically adds a number in parenthesis after each filename. The following steps explain how to use this multiple file renaming feature:

  1. First, make sure all the slide files are sorted by name, then select them all, as illustrated below.


      Select all the files to rename


  2. Right-click on the first item and choose Rename from the drop-down menu.

    Select rename


  3. The text of the first item will now be selected, as illustrated below. Type a name for this presentation that is unique and will ensure that the multiple presentations sort in the correct order (like Presentation 1, Presentation 2, and so on).

    Enter presentation name


  4. Now when you press Enter, Windows will rename all the files, adding a number in parenthesis to make each filename unique, as illustrated below.
