Camera settings, three little circles with legs on the right of the go app, select the camera in the middle top, select video size, choose 1920*1080 then select 120fps with the word slow below it, tap on the main screen on the left and every thing you video is in very slow motion.
I'll find a vid for you.
Well, is it just automatically slow? I picked the 2.4k option at 60fps so I could slow down the video later if I wanted. Am I missing something or is that a viable option as well? I assume you could record at 120fps in "normal speed mode" so to speak then then slow down the video where you want in post production? Sorry if it's a dumb question/assumption. New to this and thinking of how I do that with video on my iPhone to slow down certain frames when I want to later....Much easier. You can play with editing later. Have fun.
The thing is that many apps and displays can play back correctly at different frame rates. The "slow" button probably alters the header so that the recording is at the higher frame rate but tells the app that its a slower frame rate.
