Hey guys, flew my Mavic for the first time yesterday in 4K 30fps. I noticed the feed was really laggy / choppy. When I turned the aircraft around it would take a second or two for the feed to catch up. I'm wondering if the 4K footage is too much for my iPhone 6 to cope with? When I played the video back on my Mac it was great. I know 4K needs a lot of processing power, so I feel my phone is struggling? Or is the feed not streamed back as 4K? I have bought a Sandisk 128GB ultra sd card type 3 (somewhere along those lines) hoping that may fix it. Has anyone had any similar issues? Remember, the video is fine on playback on a Mac the issue is when flying. Thank you in advance for any help The Mavic Pro rocks by the way! I friggin love it!
