Hi all,
We've finally had some nice days of weather here where I am, so opted to go out and finally test Waypoints 2.0, and must admit, it has let me down, when I compare it against Litchi Waypoints with my old Mavic Air...
First off, not being able to program a mission offline (with the drone off), is a HUGE omission from DJI... I know some people who program missions with dozens of waypoints, with custom actions and behaviours at each waypoint, and can easily drain many % from a battery while programming the mission, which is inexcusable.
But to me, an even more important point, is how the M2P performs movement interpolation between each waypoint. It appears movement interpolation is performed logarithmically, in pre-programmed jumps, even in Arc mode with maximum curvature between waypoints, instead of a smooth, linear fashion.
Allow me to explain further... My intended use for Waypoints is to program cinematic movements that would otherwise be difficult to smoothly execute using manual controls, such as starting a shot with the drone yawed to the right and gimbal down to -30 degrees, whilst flying straight ahead, and having the drone gradually straighten out the yaw of attack and having the gimbal gradually raise up to 0 degrees by the time it reaches the next waypoint, to create a type of sweeping reveal shot. Yes it can be done manually, but being able to do this automatically using a Waypoint mission is a huge time saver.
With my old Mavic Air and Litchi, this was done in a linear fashion, and the results were sublime, generating completely smooth cinematic movements.
With the Mavic 2 Pro and Waypoints 2.0, the movement is jerky, and looks as if the drone is constantly hitting the proverbial gas pedal with a lead foot, leading to jerky footage. I believe it is the drone itself performing this logarithmic motion, as I can leave the gimal at 0 degrees, and just have the drone perform a simple right or left turn at 14km/h, and I can see the motion lurching.
I feel this is either a deficiency in the way DJI has implemented Waypoints 2.0 in the M2P's firmware, or a bug in the DJI GO 4 app and how it uploads the mission to the drone for execution.
We've started having snow here again so cannot test Waypoints in Litchi with the M2P, but that will be my next test, to see if the drone is actually capable of smooth, linear Waypoint movements, which if smooth, would leave me to believe it's a software issue with GO 4.
Sorry for the long-winded post, but I wanted to try and make myself clear with what I'm experiencing.
Has anyone else seen this sort of jerky movements using Waypoints 2.0 in Arc mode? I've seen a few sample flight videos post here that also seem to be jerky...
Cheers
