    What do you use for playback of SJ8 4K 60fps videos? I have both a PC (GTX660 video card) and android box and neither plays the video smoothly. Audio/video out of sync, or freezes, etc. Tried Kodi, VLC, PotPlayer, etc, nothing works.

    First of all you need to copy the footage to your computer, i doubt you can play off the camera in mass storage mode, or the memory card in a card reader.

    So yes all I do is copy the mp4 files to my PC, not edited in any way.

    Maybe more powerful PC would help?
    What connection do you use for monitor, DP or HDMI? Google search gives, that GTX660 can handle 4K @60 only through the DP. HDMI supports up to 30 fps.

    Have you used H.265 ? that will make a lesser computer choke on the footage.

    I don't have display port on my computer monitor, so cant try. Maybe on the android box the hdmi is the bottleneck - or getting downscaled to 1080 for my tv.

    I believe when choosing 60fps on camera only H.264 is available (4K).

    I guess there's no hope of this being fixed. Using f/w 1.31. It's related to having FPV mode On, so it's not my PC. The video 'skips' or jumps when you pan side to side. Turn FPV mode off, and it's smooth. You can actually see it on the SJ8 display as you're recording so it's not a playback issue. It's obvious what's happening: the processor is insufficient to do 4k60p + FPV mode at same time. :|
