So some media players don't know if you wanted to record a slow motion clip or a normal motion clip with a high frame rate.
Consider a normal 5 second video is shot 30FPS. When you play it back it will be 5 seconds long.
When you shoot at 60FPS this is doubling the frame rate. If you play back the 5 second clip you recorded it will take 10 seconds to play back as you shot it at double the frame rate. So If you shoot 5 seconds @ 30FPS it takes 5 seconds to play back. If you shoot 5 seconds at 60FPS it will take 10 seconds to play back. If you shoot 5 seconds at 120FPS it will take 20 seconds to play back (and so forth).
Usually media players will play back the files at normal speed with a high frame rate and to achieve slow motion you will simply reduce the playback speed. However some media players will insist on playing back the files at 30FPS and as a result, this is giving you slow motion playback.
