I made a 10 minute cycling video with the different modes of stabiliztion that the DJI Action 4 offers. I do each stabilization mode in full screen, then do a comparision of all four (including no stabiliztion for comparision ) on one screen.
NOTE: for some reason YouTube degraded the quaility when uploaded, even though it was uploaded in 4K. The footage on my computer is very sharp, just not on YouTube.
You forgot the comparison with Gyroflow = stabilisation in the camera off!
Action4 will record gyrodata in :
4K/2.7K 4:3 24/25/30/48/50/60 fps wide. video
4K 16:9 100/120 fps wide video
