ChrisJ4203, you’re saying that by default, the entire video is not slo-mo when you choose the slo-mo option. Not that you can answer this, but why not? If this is the case, I have to wonder why Apple arbitrarily decides what to put in slo-mo and what to put in regular speed. I do see the option in edit mode to change it. But I would think if I choose slo-mo, the whole thing would be in slo-mo, THEN if I want part of it in regular speed, THEN I go into edit mode. I want to decide, not let Apple decide.
The white circle isn’t the toggle for front and rear camera. That’s something else. The white circle appears after pressing the record button. It appears to be a pressable button of some sort.
***I just found out the purpose of the white button: it captures a still of the video at the point in the video you’re at when you press it.***
