What are the limitations of slow-motion recording on the iPhone 15 Pro

1. Resolution is limited to 1080p HD - The slow-motion options max out at 1080p resolution, even though the iPhone 15 Pro can record regular video at up to 4K60 with all cameras[5].

2. Frame rates are limited to 120fps or 240fps - While 240fps allows for very dramatic slow-motion effects, 4K 120fps slow-motion recording is not supported[5].

3. Slow-motion is only available in the dedicated "Slo-mo" mode - You cannot record slow-motion video in other modes like Video or Cinematic[1][2][3].

4. Editing slow-motion clips is limited - You can adjust the slow-motion section by dragging the white vertical bars beneath the frame viewer, but advanced editing options are not available[1][2][3].

5. File sizes for 1080p 240fps slow-motion videos are very large - This can quickly eat up storage space and make sharing and editing more challenging.

So in summary, while the iPhone 15 Pro has excellent video capabilities overall, the slow-motion mode is limited to 1080p resolution and 240fps max frame rate. 4K 120fps slow-motion, which would provide the best balance of resolution and frame rate, is not supported. More advanced editing options would also be welcome.
