OK, no problem, I noticed that the Windows software doesn't support compressed files. But I tried to use phone app, which DO have mp4 format, but, unfortunatelly, the camera stucks, there are some fluctuations on image, then it frezes. Can ZWO technical support investigate this behaviour? I use a Motorola Edge 30 Fusion with USB3 OTG. I also used original cable and 3rd party cables, same issue.
Please check in the link a small video to see what I mean:
