First of all, you need to open Mac’s Keynote software on your Mac. After opening the program, select File and then Open to browse for the PowerPoint file that you want to be converted into a DVD format.
After you have opened the PowerPoint file, click on File menu again and select Export. Then you will have various options to export the file into. Click on “Export as QuickTime.” Select this option and click on the Export button. Your file will be converted into a DVD-friendly format and all the audio and video components will be converted as well.
After the exporting process is complete, you need to open iMovie from your computer and import all the audio and video files exported by Keynote in the step above.
On the timeline of the program, you will be required to drag the audio and video files together. Make sure you set the starting and ending points in line with each other. In case you do not do this, your file’s audio and video will not be in sync.
Once you do that, click on the Share menu. Select the option iDVD from the menu. This will ensure that the file you edited on the timeline is burned onto a DVD. Insert a blank disc in the disc drive of your computer in order to proceed.
After the burning process is finished, your DVD is ready. You can now playback your PowerPoint slideshow on any DVD compatible player.
