Hey - I have a new Pocket 2 and tested it in a church.  I've posted the video for you to see the "shadow-lines."  Any idea what's going on?  2K 60fps / 60hz in United States

No idea,
It could be due to some light reflections to the lens protector?
Were you using some ND filter?

Turn off the lights, then you will see no shadows.
Look at the case of the lights.

Hi, thanks for reaching out. Could you please retry by shooting somewhere outside or inside with natural light to see if the shadow still exists? If so, please provide us any original video on google drive, our engineer will help to check further,

Thanks!

Would u plz provide the original video?or just show the caption so that i can check the shutter.

my guess is about the shutter speed and light AC freq.

AC generate light with a fixed freq. say 60hz.
the light goes dark and dim with a freq of 120hz.
since it is so fast, human eye cannot notice.

if the video shutter is much smaller than 120hz, each frame captures not enough light of a AC freq. the shadow will be seen.

it is common for any kind of video recorder.(modern lights freq is different, this issue may not happen. usually some old AC light)

Try shooting outdoor. Could be something related to the frequency of the lights.
