shoot at 24,,,,,,,,,,,,,,,,,,,,,, cool channel, I like your voiceover
Was hoping I could help if you were using an iPhone. There's a great editing program for iOS and iPadOS called LumaFusion that would fix your issue.With the LG G6 at 4K 30. Unless I learn something different, I believe this is an iMovie hiccup as the phone is always set to 4K 30. Sometimes iMovie just brings in footage, or changes the footage to 24. What I'll do for now is when I begin a new project, bring in a single short clip and export it right away to YouTube to confirm it's at 30. Kind of a pain in the neck but I can work with it for the time being.
