Sorry if this has been asked before but a search found answers all over the chart so I thought I'd ask it here for my specific camera in case that makes a difference. I have a SJ7 Star camera. I'm new to this but I'm heading out on a trip in about 10 days where I'll be using my camera on my motorcycle. I'll probably be shooting most of my bike video at 1080P / 60 fps with gyro on. That's based on what seems to be a consensus I'm seeing. But I'm also curious about what amount of time I could shoot in 4K / 30fps for other stuff. I'm trying to just get a general idea of what to expect. I have a 64GB card but when I saw how memory is eaten up so fast, I ordered a 128GB card today - one that is verified to work with this camera on another thread in this forum.
