Hello, I used 2.7k to make some videos since 4k has no stabilization(??) and on my computer they look like a cube, huge black lines on left/right. So please advise me about gopro 5 session, what is the best video mode 2.7k 30/24/48 S/L/M vs 2.7k 4:3 what do all these numbers and letters stand for and what is the best mode for the vids to be watched on MBP 13' retina display? Thanks
