I'm about to release an add-in for this, but it'll only be available for Windows PPT, at least for now. But you can manually do a lot of what it does: Save a copy of your original presentation. Let's call the original O and the copy C. Open C Change it to 16:9 Leave C open while you also open O and arrange the view so the two presentations are side by side. Step through the presentations a slide at a time.
A dropdown menu will open with several options. Click on Custom Slide Size to open the Slide size menu and modify your presentation's dimensions. The Slide Size menu opens, and now we can change the slide size using the dropdown options. Slide size menu in PowerPoint.
On each slide, delete any shape/picture in C that's gotten distorted, select the same shape in O and copy/paste it into C. A bit tedious but you get into a rhythm and it goes by pretty quickly. And definitely it beats re-creating/recropping all those images. PowerPoint Help: PPTools: http://www.pptools.com.
I would like to report a bug in PowerPoint 2001 for Mac.ppt files saved by PowerPoint 2011 for Mac are considerably larger than the originals. If I edit a.ppt file created in PowerPoint 2003 for Windows and save it in PowerPoint 2011 for Mac then the result is almost ten times larger than the original. The amount of the size increase seems to depend on the number of shapes, that is, the more shapes you have in the source.ppt file, the larger is the output saved by PowerPoint 2011 for Mac. Below is some statistics: #slides #shapes Original size Size after save in PowerPoint 2011 1 103 29 KB 299 KB 5 1059 250 KB 3.1 MB 10 2355 508 KB 6.6 MB 20 4190 864 KB 11.5 MB 50 11426 2.4 MB 31.4 MB 77 15880 3.3 MB PowerPoint dies Also note that the time to save a.ppt file in PowerPoint 2011 growths exponentially with the number of shapes. Saving of a file with one slide and 100 shapes takes less than a second, but saving of a file with 50 slides and more than 10K of shapes takes more than a minute! The worse is that PowerPoint 2011 dies when saving really large.ppt files, with more than 15K of shapes. PowerPoint 2003 for Windows and PowerPoint 2008 for Mac have no problems reading / writing the observed files, so it seems to be a regression in PowerPoint 2011.
The trouble is only with saving in the.ppt format. Saving as.pptx always works OK. I analyzed the saved files using the tools included in the Apache POI project (Apache POI is a set of APIs for Microsoft Documents and provides a programmatic way to walk the PowerPoint stream and examine the low-level structures.
It appears that PowerPoint 2011 attaches additional data to every shape in the presentation and this addition data is a mini-OOXML package containing two entries: downrev.xml and shapexml.xml. Very schematically it can be outlined as follows: Original shape container as saved by PowerPoint 2003: EscherSpContainer(type=0xF004) EscherSp(type=0xF00A) EscherOPT(type=0xF00B) Modified shape container as saved by PowerPoint 2011: EscherSpContainer(type=0xF004) EscherSp(type=0xF00A) EscherOPT(type=0xF00B) EscherUserDefined(type=0xF122) The contents is a OOXML package containing the following entries: rels ContentTypes.xml drs downrev.xml shapexml.xml The size of the attached OOXML package varies from 2100 to 2600 bytes. Multiplied by the number of shapes it perfectly explains why the resulting.ppt is larger in size. It would be good to not include this OOXML attachment in every shape in the presentation. If it is some kind of round-trip data required to preserve features not avaiable in earlier versions of PowerPoint, then include it only if necessary. I'm testing on MacBook 2 Ghz and 2GB of memory, MAC OS X 10.6.5. PowerPoint 2011 for Mac update 14.0.1 (101012).
