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 interested in exporting my decks as MP4 videos that I can post to our Office 365 Video portal or Screencast.
The presentation is around 50 slides, some of which contain conventional narration over animation, while the others (probably half) contain a screen recording as a video object. The videos within the deck auto-play, and every slide has timing so they auto-advance.
Here's the problem: when I go to export this presentation as a 1080p video, it takes a FREAKING AGE! I've been sitting here watching it export now for about an hour, and it's only 50% complete. It seems to get exponentially slower as it goes. There shouldn't be much to do here, just sequence the slides into a video stream and save it to a file. I can do the same thing in Camtasia in 6-8 minutes. Any ideas? Thanks!
Hi
I came across this solution by sheer coincidence.
Shortly after starting to create the video file and while doing it, try "save as" for the PPT file.
Just save it to the same location with a different name.
What happens - at least with me - is that the video file is immediately complete and ready.
Don't know why and how but works for me.
So, time has moved on and I just spent the last 7 hours waiting for my 43 minute video to export. I am here simply to inform others that this issue has not been rectified Greg Edwards
Greg Edwards Did you pause the sync function on your cloud (lower right on taskbar)? Cloud sync slows video rendering. Sync pausing improves performance from extra slow to slow/medium.
Hi All....I have been through this 🙂
Its best if u use other free desktop recording software like VSDC which saves the ppt video or anything instantly as soon as u hit the 'stop recording' button
Follow is the download link. Hope this helped.
Download VSDC — Free Screen Recorder for Windows PC (videosoftdev.com)
Same issue here, mp4 export took forever but there's no bug, only an Intel i5 processor with 8Gb ram and low performance integrated GPU.
86 slides and 4 hours of audio comments (it's a training course) took 7-8 hours to be exported, sometimes it seemed to be stucked for half an hours (!) but then the job has been completed.
I hope this helps, it's a slow process done this way.
Same here, 3h studio, sadly neglected to share the show when recording with Skype for Business. Presently I just have the sound and matched up that to the slides to send out everything to a 1080p video.
After three hours now and the advancement bar is all things considered at 20 %. I don't think this will complete inside a full business day. All in all, what is happening here? There should be immense space for execution upgrades for whatever calculation is being utilized. Kindly deal with that!
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.
I had the same problems using MP4 format as it is very large of course it will take forever so a friend of my ages ago told me if you wane have the same resolution of DVDs or any formats or your personal from the phone Mp4 vids you need to download DivX or Xvid software it should be free but it will make a big difference in size and no video quality loosing it is same as cd or wave file to Mp3 so that's it, there is all sour of different formats u can choose and give it time first convert and share over network Greg Edwards
To everybody who's following and reading this thread: it might be useful to use some kind of screencasting software to capture the Powerpoint. I think this is faster than the internal converter of Powerpoint.
I'm using Screencast-o-matic, it has a free version for videos under 15 minutes.*
A) If your Powerpoint already has narrating (and annotations) embedded
1) Then you open up your screencasting software (I'm using Screencast-o-matic, it has a free version for videos under 15 minutes)
2) Replay the Powerpoint in fullscreen while recording using Screencast-o-matic. Don't forget to add the system audio. This way the embedded audio in your Powerpoint-file will be captured by the screencasting software.
B) If your Powerpoint doesn't have narrating (and annotations) yet
1) Then you open up your screencasting software
2) Play the Powerpoint in fullscreen while recording the full screen using Screencast-o-matic. This time, you'll be speaking in the microphone.

* No, I'm not affliated to Screencast-o-matic, but I do have a subscription.
I have the same problem trying to save the video as .mp4. Would this be faster in another format?
Same here, 3h workshop, unfortunately forgot to share the presentation when recording with Skype for Business. Now I only have the audio and synced that to the slides to export everything to a 1080p video.
Three hours later now and the progress bar is at most at 20 %. I don't think this will finish within a full workday. So, what is going on here? There must be vast room for performance improvements for whatever algorithm is being used. Please take care of that!
- best, tb
Ok, my issue was quite another. I totally got timing wrong and was putting the absolute time at each slide, not the relative one from the last slide. Mea culpa.
Eventually I used some macro voodoo to recalculate that time and waited for about as long as the presentation itself was for the video to be finished.
