Hi Vipitis,
Yes, the M1 I have is the 30Hz version.
I've tried video capture on both a Samsung Galaxy Tab A and my PC, which is a Ryzen 7 1700. On the PC it captures the full 30 fps without an issue. On the Galaxy the captures that I've done have only reached just over 9 fps, so the host processor seems to have a great deal to do with the capture rate.
Once I work out where to post some videos I'll put a link up here. I tried attaching a video previously for my banding question, only to find out that there aren't any supported video formats that are postable, hence the gif.
