I don't doubt sensor resolution but another important parameter is the speed meaning how fast data can be read from the sensor and for cheap sensors this speed is low so that manufacturers do the binning trick i.e. reading every second row thus effectively reducing resolution at higher frame rates and do upscaling.
If that is not the case then probably the CPU unit is not able to encode using lower quality parameters that again may lower effective resolution.
Perhaps you know that better than I do since I see you are from DJI. I have already sold my Action 2 and deleted the test video but others can try luck shooting resolution charts |
