I'm trying to fully understand X-T3 video autofocus, and I'm curious about the above. When I look at the display as I record video, I see "AF-C" in the lower left whether the front dial is set to AF-S or AF-C. (MF comes up too, of course, but let's stay with AF.) My experience, and my interpretation of the manual is that there's basically MF or AF-C as the top-level focus modes for video; and under AF-C there's either "Multi" (full automatic) or "Area" which focuses on what's inside the focus box.
To autofocus on something and hold that focus, I've set the AF-L button to "Switch" rather than "Pressed", so I can lock the focus that's currently acquired until the next press of the AF-L releases it. This is akin to the "Shot" focus functionality, stopping it from refocusing.
The below table doesn't seem to apply to Movie mode. In my testing, AF and Area do the same thing (Area), and they do this regardless of whether the physical dial is set to AF-C or AF-S.
@Cameramoto, @Attila Bakos - Do you also get this, or does your experience contradict this? I would be interested to get the AF-S functionality in video without the AF-L workaround. Maybe I've got something in my settings that's blocking this for me?
