Ever since the 17.4.1 update, any iPhone videos I import to windows stutter and strobe. The audio is fine. Vidoes I imported before the update still play fine in Windows and they all play fine on the iPhone. I've rebooted all, updated graphics drivers, disabled autobrightness/true tone and a dozenother internet remedies....... but still no joy. How can I fix this? Best, Kelly
I found the problem or at least a fix. I’ll post it here so some other poor soul like me doesn’t have to lose hours of their life to resolve same problem…..but first…….
At the point I posted here, I was less interested in classing and assigning blame than I was identifying what was causing the problem, so I could correct it. Having found the problem, or at least fix, I’ve moved on from that position now. FWIW, I posted the same issue at the MS/Windows community help forum, and I'm sure you can guess where the finger was pointed there. If you search the net or even this board, there are zillions of examples of video stuttering/lagging caused by iP updates not only on third party software but on the iP itself.
The fact that the problem appeared when I attempted to view iP videos made the first hour after 17.4.1 update when using Windows based viewers and editors and was not present on any previous iP video I’d ever made is a
pretty solid indication of when/how the problem occurred. This particular Windows machine doesn’t get updates because I use it to run machinery and many other things and just don’t want to be subjected to the same compatibility issues nonsense from updates. I didn’t initiate the iOS update. It occurred automatically. I have not disabled auto updates on the iP, because, well, frankly, iOS needs them as should be obvious to anyone by the frequency which they occur.
To answer the other question, I transferred the videos the Windows machine the same way I have for the last 10 years. I connected the iP, copied and pasted them onto my windows machine, and then viewed them locally. However, the problem is identical if I attempt to select and view the video directly from the connected iP directory viewed from my Windows PC. I also checked and made sure I had ample memory on all devices.
By coincidence, about the same time this issue started, I started getting emails from folks with pictures attached in HEIC format which I couldn’t view from W10 machine but could on my iP. I asked why they started sending pictures in that format and they were unaware they were…….so I of course asked if they were iPhone users……and YES they were. So for grins, I went to my newer MS Surface tablet, and sure enough, I could view those pictures and also the post 14.7.1 iP videos from that machine.
So instead of fiddling with the brightness, true tone, and other lighting settings recommended on all the other net sources, I changed the camera capture setting(s) from high efficiency to compatibility. Now other than this problem, it’s been a while since I’ve looked at these settings but reading the setting description, it appears to be a new option directly affecting FPS and (new) video and picture capture and formatting.
This change solved the problem.
I went back and re-read the iOS updates. I see no mention of such a change to video/photo format settings, but I do know that I didn’t change it and given the high efficiency formats are relatively new, I think it’s safe to conclude it was indeed an unmentioned part of the 17.4.1 update.

It's not always the iOS update's fault! Many things can cause phone problems. If you tell people you think it's an iOS update, it might make it harder to fix or find a solution for the real issue.
Remember, the right question often leads to the solution!
iOS updates aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. The majority of the issues after updates might stem from underlying, unmentioned factors. Updates won't typically alter personal data but may refine settings or features. Backup before major updates for safety. Review Apple's update details and backup advice for a smooth process.
Kindly consider checking your settings and addressing any device issues before attributing the issue to external factors. This could be a pure coincidence that the iOS update affected the iPhone functions.
Before initiating a standard iOS update, it's advisable to create a backup. Have you completed this step? If yes, proceed with the restoration from the backup.

I am not clear how you did the transfer.
Microsoft support says --> Import photos and videos from an iPhone to PC
Videos imported form iP-13 pro to Windows viewer editor stutter and strobe since iOS 17.4.1 update
