Thank you for bringing this to our attention. There is likely an issue with the setting of the flight speed when DNG is in use with the new Virtual Stick controls. Usually when DNG is selected we set the flight speed to 1 image per 10 seconds because that is what DJI specifies as being the max DNG frame rate. That might not be being done properly with the new manual controls system.
From the DJI documentation:
"When the photo file format is RAW, the time interval between two photos cannot smaller than 10 seconds. If the input exceeds the camera's capability, the taken photos may be less than expectation."
So Map Pilot Pro was likely telling it to take images assuming it was going to be able to do it once every 2 seconds but the camera only supports readout at 10 second intervals. If this is in fact the issue we will likely have to slow the aircraft down significantly as we have done for other waypoint flights in order to collected the designated amount of overlap properly.
