Also found High frame-rate doesn't guarantee fast shutter speed. In my case: I have 60 fps with 1/30 shutter speed: This is actually completely normal and possible! Here's why: Frame Rate (60 fps): This means a new frame is captured every 1/60 second (≈16.67ms) Shutter Speed (1/30 second): This means each individual frame is exposed for 1/30 second (≈33.33ms) How this works: The camera sensor can be exposing one frame while simultaneously reading out the previous frame. This is called rolling shutter operation, which is standard in CMOS sensors.
