PPT ---> MP4: Automation

[NathanMarder]

PPT Slide ---> MP4: Anyone have experience automating the extraction of video content from a powerpoint slide so that you can store it as an .mp4 or .mov on a local device? Perhaps someone has tried to do something similar:

For some context, I have already written a python script using the python-pptx library that creates a PowerPoint from a directory of images and videos — where each slide is one file, fit to the height and width of the ppt slide (16:9). Then I have a bash script that integrates this with a linux file system. This is relatively straight forward to do — however I am also trying to create a script that can work in the reverse direction, which the pptx library does not support. PPT natively exports slides as PNGs or the ENTIRE presentation as a movie, however it can not do both. For example, if I want slides 1-6 to be a png file, but slide 7 is an embedded movie – I want to just extract that movie and save it as a mp4 or mov file in the same manner and in the same directory as the pngs are saved. I'm not really up to speed on how ppt handles its media or xml file structure - but wanted to see if anyone had any ideas on where to start or had already taken a stab at this.

Thanks!
