Help would be appreciated

To get slo-mo video, what you do is shoot at a higher frame rate than the video will play back. Since in the U.S. we use a format that plays back ~30 frames per second (fps), when we shoot at a higher frame rate (generally in multiples of 30), playback at 30fps will be slowed. Many devices are capable of 60, 120, and even 240 fps, and the corresponding playback speed is probably obvious to you: 60fps=1/2 speed playback, 120fps=1/4 speed, and 240fps=1/8.
Think of this as the antithesis of timelapse. In a timelapse we might record, for example, one frame every tenth of a second (not a frame every 1/30 of a second like in normal-speed 30fps recording). That gives us only 10 frames per second, so it takes three seconds worth to get the 30 frames that play back per second, which gives us a video playing three times faster.
Recording video at higher frame rates takes more resources, so we suffer an inverse correlation between resolution and frame rate. For example, few hybrid cameras shoot 4k resolution at 60fps, and fewer still at 4k 120fps -- but many shoot full HD (1080p resolution) at 60fps or 120fps.
Cameras refer to the frame rate with p, by the way, so you're likely to see 4k/30p and 4k/60p, or maybe HD/30p and HD/60p, as options, with the p meaning fps. This is not to be confused with video or display resolution of, say, 1080p or 1440p, which has nothing to do with frame rate.
