This likely comes down to exposure time. When taking a video there are several frames being captured in a steady sequence, often 30 or even 60 frames per second. With a photograph though the phone can take its time capturing the highest resolution single frame it is capable of, and to do so it exposes the sensor for longer than it does for the video. Because the sensor is capturing data for longer it is also capable of capturing undesirable movement of the camera for longer, increasing the potential for motion blur. This can be mitigated by forcing the phone to reduce the exposure time and increase the sensitivity of the sensor to compensate, which reduces the overall quality but makes motion blur less of an issue. Sometimes this adjustment is summarized in a “sports” or “action” setting in the camera app.
