Keynote and Recorded Presentations

audiokeynoterecording

If you "Record Slideshow" in Keynote then it'll listen to your computer's microphone and make well-sync'd presentation you can save to .mov and share, but it's pretty damned big, even for a short presentation.

Is there any way to export only the audio and the slide timing info from Keynote once your recording has been made?

The options I can see are iPod, HTML, Images, PDF, PPT and Quicktime. With a bit of faff I can extract the audio from the Quicktime, but I'll have lost the timing info.

Ideally I'd be able to export "Images with Timing info" which would give me the images and a file of timestamps linked to filenames which I could use to pair the two up.

Does such a thing exist?

Since keynote files are just zip archives with XML documents and assets stored in a fairly obvious folder structure, I'd start with moving your Keynote into a folder with nothing else and use the terminal unzip command to extract everything.

The index.apxl file will have your timing information stored in plain text and encoded as XML - so you might be able to parse that with an XML tool or otherwise extract your timing.

I don't think the file is documented publicly other than the various public namespace declarations in the header of the file, but it's a start to cracking your timeline problem if you don't mind spelunking in XML and reverse engineering the commands recorded within the file.

AppleScript or Automator Workflow for Bulk-Converting Powerpoint Presentations to Keynote

I couldn't figure out how to get Automator to do it, but I was able to beat AppleScript into submission. Just save the following as an Application in the AppleScript Editor, then drag the files you want to convert onto the icon. It will prompt you to choose a folder where the converted files will be placed.

on open droppedFiles
    set theDestinationFolder to (choose folder with prompt "Choose destination folder") as Unicode text
    repeat with theFile in droppedFiles
        tell application "Keynote"
            open theFile
            set theSlideshow to slideshow 1
            set theDestinationPath to theDestinationFolder & (name of theSlideshow)
            save theSlideshow in theDestinationPath
            close theSlideshow
        end tell
    end repeat
end open

(I don't really know what I'm doing with AppleScript. If there are improvements that can be made here, I'd like to know about them.)

How to generate dynamic keynote presentations

You could create your keynote presentation as a series of separate files (either slides, or sections, eg. slides 1-20, slides 21-25, slides 26-40) and then merging them using Automator. This way you could simply replace slides 21-25 with alternative versions prior to merging?
