Hi,
in the newest version of the Mavic 2 Pro manual are some suggested settings to correct the barrel distortion in DLOG-M:

But where should I apply these settings?
They don´t look plausible in the fisheye lens effect:

no correction:

0.05 has nearly no effect:

-5 looks better, but thats not what is stated in the manual?!:

So my question is: where should I apply those values in FCPX??

Here is a video on the matter, plus an 'effect' you can download and easily apply in FCP, etc

Hi theothernt.
Thanks for the info.
I know this effect and it works ok, but the manual doesn’t state that we have to download anything to correct the distortion.
So my understanding is that it can be fixed just with fcpx.

Are you referring to the DJI Mavic 2 Pro manual?
The 'effect' file is just a convenient way to apply the fix - it's the same as if you'd applied the correction manually via the panels on the right (in FCPX)

I am referring to this section of the manual.
Sorry, forgot the picture in the original post.

I've just tried those values out in FCPX, and like you... they don't seem correct...

(in the meantime, I'll do some research - maybe someone else will chime in!)

It would be terrific if someone from DJI could explain how those settings are supposed to be used.

...well, in the meantime I made my own effect that works quite well using Apple Motion, but the values I used for the distortion have nothing in common with the ones from the manual.

I'm in the exact same boat... I'll just wait here for someone cleverer than me to tell me how to do this, because I cannot figure it out for the life of me!

...so there is no-one who could tell me how to use these values in FCPX??
@DJI: I think at least the guys who wrote the manual should know!

In case you are still looking for the  answer to this, DJI has given instructions for how to use the distortion correction in FCP X and the other packages, in the DLogM to Rec. 709 User Guide available from the support pages. You have to download and install the Alex4D Wide Angle Fix plugin and use the correction factor in there. I hope that helps.

Hi Drone filmer.
Thanks for the heads up. I didn't know this manual. Wondering why no one from DJI pointed me in this
direction?
I wrote my own FCPX plugin in the meantime but now I can compare it with the recommendations .

Hi, Sorry for the late response. Please kindly perform IMU calibration. I have clarified your concern with our higher team and I would recommend keeping an eye on the DJI website for any further updates. Thank you for understanding and patience.

Hi Wingspeed,
thanks for the response, but how should an IMU calibration help me finding settings in Final Cut Pro?
