    A quick forum search would have given you the answer.. But luckily I did it for you...

    Looks like you are not alone with that issue

    hi all,

    Even I am facing the same issue.
    Slow motion videos are getting flickering..


    Any resolution for that ???

    yea i ran that slow motion mode,it became darker ,maybe it's not a problem,just like the higher shutter speed in a frame?less light to record?

    Cupcakes almost solved the mystery ;)

    OK I'll give you two hints...
    1. 480fps is 8x faster than 60Hz and 9,6x faster than 50Hz. What AC power do your lightbulbs use?
    2. at 480fps the phone has roughly 0.0020833333... seconds to record enough light to create a frame. Is is much?

    what are you trying to conclude then with this theory? will it remain the same?

    I'm trying to give you a hint that will lead to EUREKA! And that will be the end of the thread probably

    flickering will be in artificial lighting..

    OK, try to turn of and on the light in a room, 1 second on, 1 second off. Take pictures every 2 seconds. All your pictures will be either dark, or light. Judging by pictures you will not be able to tell what happens with the light in the room.

    If you change the 2s interval to 0,5s, half of pictures will show light room, and half dark room.

    It's the same when you start recording in high FPS (like 240, 480) in a room lit with AC powered lights.

    The dark pictures come from underexposing, so if exposure time for each frame is short, the picture will be darker at the same ISO, and you can't increase ISO too much as you loose quality.

    bingo, but only AC powered, as DC powered might be stable enough :)

    actually understand the mechanism.. the screen will definitely get dark since it takes 480fps.. so the shutter has to be extermely fast.. ISO will be low to reduce noise.. it's happens in all mobile super slow motion tech.. it's not an issue.. and that's why all company opt to advertise their slow motion in good lighting conditions..

    it's nothing to do with ac and DC.. the shutter speed is high as 480fps.. so each frame will be captured in 0.0020833333333 secs .. that's extermely fast man..

    you are mixing flickering with dark frames. Dark frame comes from short exposure, flickering comes from being able to record the light switching cycle equal to voltage switching (50Hz or 60Hz). Remember your eyes are not perfect, sometimes your camera sees more ;)
