No

The next update, due soon if FCPX export and bug fixes

I don’t know, yet, what the plan is after that

I'm also a Mavic 2 Pro owner filming in 10bit, thus without lens distortion automatically applied, as many and many other owners of this popular drone (the most popular maybe...), and the lack of built in barrel lens correction, a standard effects in all other NLE I know, is the main concern I have using LumaFusion !
Otherwise it is a incredible solution as it could smoothly display and use the 4k 10 bit videos from this drone on my iPad Pro where my high end MacBook Pro is in pain and where I have to use proxy files !

I've only got a Mavic Pro

Can you tell me why you get distortion in 10 bit ?

The Mavic 2 Pro can‘t correct it by itself. Lens correction only works for 8bit videos and photos with the built-in processor of the drone.

An automatic correction of the barrel distortion is applied natively when recording video in 8-bit, but the distortion is not corrected when filming in 10-bit (DLog-M and Hybrid Log Gamma or HLG).

Here‘s a good article about it and how you can correct it with other software, perhaps you can copy to LumaFusion ;)

I wonder why it doesn't do it in 10 bit?

I suppose it's a speed/buffer thing

I'm sure I read somewhere that it buffers 8 frames??

Apparently there isn’t enough overhead in the Mavic’s Processing unit to correct this..

Now I corrected the files on SD card with Premiere Pro with my PC. It worked very well.
I only did the lens correction (-9 for Full FOV and -4 for HQ mode, H265 4K 10-bit Mavic 2 Pro).
I imported the corrected video file on my iPad Pro and colour corrected it.

It would be better to do this all in LumaTouch, but this way is also ok.
