Exporting to video takes FOREVER!
I'm trying to use PowerPoint as the basis for developing some e-learning courses and instructional videos. My initial strategy was to use Mix (and I'm still exploring that), but in the meantime, I'm ...
I've been having problems with slow PowerPoint video export, and I've observed something not mentioned in the original discussion:
PowerPoint (both Windows and Mac) stops exporting when the PC goes to sleep; it does not, as Zoom or Teams video do, prevent the PC from sleeping. In these energy-conscious days we tend to set our computers to sleep within half an hour, which means that a long video export can appear to take forever.
So disable automatic sleep mode while exporting video.
- I suspect that the video export engine in PowerPoint isn’t able to take advantage of multiple cores/threads especially on Windows.
That’s why you don’t see more that 30% resources utilisation.
I’m guessing that this won’t change until MS updates this component and is such a marginal part of the system they’ve probably forgotten that it exists.
Just as an example the same single slide export in PowerPoint vs Keynote takes 1:30 vs 10 seconds.
It’s all about optimisation.
