On that video I was using the card that came in the mavic. Not sure how to get the logo off as I sent it to you tube from my djigo4 app
If I'm not mistaken, the default resolution on the DJI Go4 app is 720p. I would consider a change to different rendering software, like Resolve 15 (-free), and while there's a learning curve, you'll be infinitely more satisfied with the end results. The Mavic Pro is capable of crazy sharp images, but you must have it set up correctly. My video settings are:
Manual mode
ISO 100 -200 for best images (-use lowest ISO possible) ND filters almost always to get the proper 1:2 ratio
Shutter to around 60 (-should not be more than twice the frame rate)
Set white balance for ambient conditions (-Plenty of Youtube videos to show you how)
Set 4k/24 fps (4096x2160 (2.7k is great too)
Now for your jerky remote responses:
Go to ADVANCED, then EXP to adjust sensitivities
Throttle down - 0.25
Rudder Left - 0.20
Backward/Left - 0.25
Sensitivity
Attitude (-how aggressive it reacts to control input) = 100
Brake - 130
Yaw Endpoint - (left/right rotation limit) - 50
Urgent Stop Mode = DON'T set to "always", set to "Breakdown"
Gimbal Settings (-the camera icon)
Gimbal Tilt Limit - OFF
Gimbal start/stop buffer - 18
Gimbal Pitch EXP - 23
Gimbal Taw settings - ON
Gimbal Pan Synchronous Follow - ON
These will smooth things out for you, and you can tweak from there. Everyone's different.
