Issue
When car is moving and there is enough movement recorded by the cameras, video becomes broken. Seems like MCU1 cannot keep up with HW3 for storing video stream and parts of the MPEG stream is lost.
Note: Issue only manifests with a moving car and enough movement in the picture (when MPEG steam rate increases sufficiently). When car is still or there isn't enough movement in the video stream, recordings are ok.
At worst the video can at times look like this:

Affected cars
Hypothesis: Every car with MCU1 + FSD/HW3 combination is affected
Note:
How to test your car
Check if your car has FSD/HW3 + MCU1.
In your car, select Software > Additional vehicle information. If the dialog has the following info, your car has FSD/HW3 + MCU1:
If all video seem clear and fluid, your car likely does not have this issue.
What can I do about this?
Open up a service case in mobile app, explaining the issue. Ask them to solve the issue under warranty.
Currently only known solution is to pay for Infotainment (MCU2) upgrade. If you choose to pay, archive documentation of the service conversation and receipts in case Tesla is forced to refund those later.
Share your test report in this thread (whether your car has the issue). If it turns out that most or even all of the MCU1 + FSD/HW3 cars have this defect, Tesla might be forced to fix the issue on their own cost for all of us. In the best case, this might give free MCU2 upgrades to affected car owner and refunds to one who paid for MCU2 upgrade themselves.
Note to admin: There are related threads previously at the forum (some of which are linked from this post). Discussions on those threads are focused on figuring out what the problem might be. This thread is separate to allow collecting reports to either support or disprove the specific hypothesis that all MCU1+FSD/HW3 cars are affected. If hypothesis turns out to be true, this would help affected car owners to have Tesla fix the issue.

Hypothesis: Every car with MCU1 + FSD/HW3 combination is affected
Note:
- Affected cars later upgraded to MCU2 are cured of the issue
- Replacement MCU1 with fixed eMMC does not solve the issue
- Issue appears regardless of the storage media
- MCU1 + FSD/HW2.5 or FSD/HW2.0 cars are not affected unless upgraded to FSD/HW3
How to test your car
Check if your car has FSD/HW3 + MCU1.
In your car, select Software > Additional vehicle information. If the dialog has the following info, your car has FSD/HW3 + MCU1:
- Autopilot computer: Full self-driving computer
- Infotainment processor: NVIDIA® Tegra®
- Connect a USB drive to your car
- Format it if needed
- Go for a drive
- While car is moving, start dashcam recording
- Repeat couple of times
