Hi. We're running EW7.4.1.9 and since a recent re-install of the laptop that runs it, our video backgrounds have started to stutter at the loop point.

The videos are the same (pre-re-install of windows 10), so there are no other changes in that regard, but at the loop point there is now a noticeable stutter. 

I presume this is a codec issue? But how do I track down what one I'm missing and where does it need to be stored?

Thanks for any help.

mp4 files. They looped perfectly prior, but now it seems we're missing something.

It's not a background that came with EW. I checked a few different videos and they're all stuttering at the loop point (although I can't remember which ones are EW supplied - it's been so long).
