Regarding your question about transferring files, see below. I can’t offer any advice on editing tools for the iPad.
I have used the DJI Fly app Quick Transfer feature to copy from the drone to my android phone (Google Pixel 6 Pro with latest updates). The DJI Fly app on the Apple store says it can be installed on an iPad. I would give that a try. Here is a video explaining how it works.
FYI, on my android phone I had to establish a bluetooth connection to the drone (DJI Mini 3 Pro) the first time to get it to recognise the drone in the app. Subsequently it has prompted me to use Quick Transfer each time I connect to the drone. Personally I find this works at a similar speed to a USB cable connection to my laptop, which I prefer, otherwise I have to copy again from the phone to the laptop. If you want to consume the footage on the iPad then I think this will be a good solution.
As I don’t use Apple hardware I can’t guarantee it will work, but maybe some Apple users can confirm they have used this…
The two iPads I have at the moment are the third and fourth I have bought for myself, and my partner is looking forward to her third one. I edit my films using Final Cut on the Macintosh M1. Both the kids are Apple iPhone/Macbook fans too…
However, give some thought to not using an iPad for flying a drone. Firstly, they are heavier than your iPhone/Android, making the whole system more cumbersome. Secondly, to get great film, we tend to fly when it’s sunny. What the iPad does when it’s sunny is dim the screen, making it very hard to see what’s going on. This is not a small problem.
Around these parts, if you want a big screen and control your drone in bright conditions, people are recommending the Tripltek - see here: https://www.tripltek.com/tripltek8. I haven’t tried it, but if I wasn’t already invested in Apple kit, and was only buying a tablet for flying, I would go for the Tripltek despite the dreadful operating system. Nothing beats brightness in the sun.
I have no intention of flying my drone with an iPad, I have the RC remote with screen. The iPad would be for editing video/photos after a days flying, especially when I am away from home for a few days staying in hotels.
I use the new ipad pro 12.9 with the M1 chip both when flying and editing.
It handles all the 4k footage with ease ,and is an amazing experience when flying with the Mini 3 pro.
An all in one package for the budding drone and editing drone bloke.
Go get one you wont be disappointed.
I chose not to get the rc with the diplay as the screen is too small ,.
When connected to the ipad the screen real estate is beyond awesome.
