Mainly iPhone related- what is the slow motion video setting good for when I can take a normal video and edit it slower in iMovie? Mainly which would result in higher quality, a 1 minute video slowed down in iMovie that is therefore longer or a 1 minute slow motion video that is automatically slower when played back?

You only have so many frames in a video. If you capture 30fps video and try to slow it down to 1/100th regular speed, youll be left with a “video” running at 0.3 FPS, so basically more of a slide show than a video.
A slow motion video captures more FPS before it’s slowed down, e.g. if you film at 3000 FPS you can then slow the video down to 1/100th speed and be left with a 30 FPS Video.
Additionally the higher frame rate means a much higher temporal resolution, e.g. you can see fast stuff happening. If you film at 30 FPS and something only takes 1/60th of a second to happen, you can’t film it happening. On one frame it won’t have happened yet, and on the next it’ll already be over. If you film at 3000 FPS you can actually capture frames in between the thing starting and ending
