What tools can convert Powerpoint presentations to video formats?
Free (as in beer or as in speech) preferred, since this is a one-time thing.

Techsmith's Camtasia Studio can record the whole of a Microsoft Pwerpoint presentation, including voice narration. Not a free product but a fully-functional limited-time trial version is available to allow evaluation before purchase.
As @saveenr describes, you can do this in Powerpoint 2013. Unfortunately the quality isn't great if you use the menu option directly but you can relatively easily overcome that with a touch of VBA.
ALT F11to open the VBA editor
Insert > Module menu and paste in the code below:
'''' Export the current presentation to a mwv movie
If ActivePresentation.CreateVideoStatus <> ppMediaTaskStatusInProgress Then
ActivePresentation.CreateVideo FileName:=Environ("USERPROFILE") & "\Desktop\FromPowerpoint.wmv", _
Else: MsgBox "There is another conversion to video in progress"
Main Menu > Run > Run Sub/Userform menu item
This will execute the macro which exports a file
fromPowerpoint.wmv to your desktop. You'll see at the bottom of the main Powerpoint window, in the middle of the status bar, a progress indicator of the export. It's likely to take at least a a few minutes.
The code above exports to 720p resolution. You can change the
720 value about to
1080 for full hd resolution. See MSDN reference for other options (although the documentation is pretty rubbish).
If you want
mp4 output format just change
.mp4. I believe the
mp4 is supported from PowerPoint 2013 but this might work with
wmv in 2010.
(Thanks to John SR Wilson for the code example).
