Hi,I'm a complete beginner so excuse me for maybe asking a stupid question. But, I don't get the 4k logo on the film roll above the red record button in the screen that everyone talks about on youtube. Under the settings it says that I have it in 4k. Does this matter? I also think the quality when I transfer to IG is very poor. Thanks for any reply.

For instagram it's best to convert your footage to the IG preferred format otherwise IG is terrible for converting the footage for you.  More information here -
