PowerPoint 2016 exported mp4 video "jerks" on some slide transitions

I am using PowerPoint 2016 - Windows 7. When I export to an mp4 video, I notice that at some slide transitions the video "jerks" (quickly flashes back and forth from previous slide). I am at a total loss as to why. I'm hoping this is something I am doing wrong and someone can help figure out how to prevent this from happening.

where it jerks: 55 seconds, 1:45, and 2:36

The same behavior occurs in original mp4 file exported from ppt. If you download the mp4 file and run in Windows Media Player you will see the glitches at the time points. For some reason, when I just run the mp4 in a browser, the jerks do not show up, I guess are "smoothed over" by whatever video player the browser is using.

You will notice there is kind of a pattern. Approximately 50 seconds between the glitches. I have noticed a more or less similar pattern, approximately one minute between the glitches, in some other tests I have done.

I also see this happen when I remove the slide timings and set the mp4 video export to advance slides every 5 seconds. In that case, the jerks happen exactly at 1 minute and 2 minutes.

The transition "jerk" never happens when I run a slideshow from within PPT. Only happens in exported mp4 video.

Slide transitions set to "none".

Any help appreciated. Please let me know if additional information needed.

If a bug in ppt, any suggested workaround?

I too have this issue. The exported MP4 from O365 PP 2016 is experiencing the same "glitch" on transitions. After the transition completes, the previous slide pops up, sometimes the entire slide, sometimes only parts of it.

I've been using PP for this purpose for many years and never had this issue, even with Win 10 x64 and O365 2016 until recently. I'm suspecting it has something to do with one or more of the updates pushed out by Microsoft. (remember the debacle where the Win 10 update 1809 would delete your user profiles if you didn't store them in a "traditional" location?)

Anyway, in October this was working fine for me (we are a corporate entity that updates much slower than public users).

I've had to resort to two rounds of encoding making the process more lengthy.

Length of video is irrelevant unless of course it's shorter than the 55 seconds (yes mine also initially happens at 55 seconds go figure)

I am a software engineer and I can tell you that this is most definitely an encoding problem. It is NOT a player problem ... I suspect that the encoding is screwed up and some players more readily ignore them. But what do I know, I only design and write software for a living.

    The issue has been persistent for over about 2 years now for me; I think though, even when a fix finally does come out for export to .mp4 file type, I'll still revert to my current 'workaround' method, which is export to wma and then use 'Handbrake' file compression converter. It is an excellent and free program here: https://handbrake.fr/downloads.php .

    I guarantee, you wont find a better, higher quality video compression & conversion software. It's also portable which means you don't need admin rights to run the app and it also does batch file conversions.

    Hope this helps!

    I have this issue across multiple players. I create a couple of these every month. I export the file as. wmv and then convert it into mp4.

    Microsoft should say they offer export to "faulty mp4"

    Hi Stef,

    Thank you. I will try this and see of it helps. I like the simple PPT and recording and also hat I can record slide by slide and decide where to be at the screen. Simple and good enough for me. It's just the export .... Thank you!
