Slow motion videos in 720p vs 1080p

Some iPhone users may not find the 720p option on the Record Slo-mo settings screen, it is because they have changed the camera formats to High Efficiency from Settings > Camera > Formats. Here you have options to switch between High Efficiency and Most Compatible. If High Efficiency is selected, you will see only two options, 1080p HD at 120 fps and 1080p HD at 240 fps. If Most Compatible is selected, you see an additional option 720p HD at 240 fps. In general, you should set the camera format to High Efficiency, so photos and videos will be encoded with the high efficiency HEIF and HEVC and thus reduce image and video file size greatly. In general, images saved in the HEIC format may only take up around 50-60 percent of storage when compared to those captured in the .JPEG format.
