I shoot the video, it goes on to my Macbook Pro where I edit it. I export it as a mov file to my desktop. Now I want to transfer it to my iPad Air. I have Yosemite OS and I can Airdrop to my iPhone no problem but when I Airdrop to my iPad it says it's sending, there is a progress bar, my iPad says it's receiving with a progress bar, but the file never appears on my iPad , so where's it gone ?? I've tried it at 4K, 1080p, mov and mp4 files, but none work. Even very small video don't work. The only thing that will Airdrop are JPEG photos.
