I got myself extra batteries with hub and ND filter just now. Got the bag and strobe light. Registered the Drone because with Strobe light its very close or over 249g.
I calibrated the compass. Do i have to do that before every flight?
I calibrated the Gimbal. Same question do i do this before every flight?

I am still messing with Photo and Video settings.
Do i want more FPS or less for cinematic shots?
I get 4k 30fps but i've seen some YouTubers suggest 4k 25fps with ND filters using the 180-degree rule (Set your Shutter double your FPS)

I was thinking 2.7k 60fps would be good enough for YouTube videos and such.

What are your go to resources for DJI Videography?

Check your props each flight for damage,  dont calibrate unless you are prompted too,   I personally like 4k 30fps for my YouTube content.  

Make sure you are very comfortable flying the thing before looking into video / photo.
