Hola, hace 2 semanas que adquirí el nuevo Mavic pro 2, y realmente estoy muy descontento de la calidad de imagen en video que tiene. Yo hasta ahora estaba utilizando el Phantom 4 pro, uy la calidad de la imagen me parece muy buenna.
Pensaba que con sensor de una pulgada, la caildad iba a ser practicamente igual, pero veo que no se puede comparar. Me esta probocando ruido en las imagenes grabadas con ISO 100 con un dia soleado.. Me parece increible, que a parte del ruido en las imagenes, tenga tan poca definición.
Una autentica decepción!! DJI a engañado a lños usuarios, vendiendo una camara de una pulgada, y realkmente no utiliza el 100% del sensor.

Puedes colgar algun video o fotos? Yo no tengo ese problema... El M2P rinde 4K 1:1 en Modo HQ utilizando el centro del sensor. En FoV pierde un poco por causa del metodo de downsampling utilizado (pixel binning). En todo caso, la imagen es excelente y puede que no este al nivel del Phantom pero el dron es 1/4 del tamano...

Hi, we're sorry to know about this situation. The Mavic 2 Pro uses a different processor than P4P and has two 4K modes, as stated on the product page, which is FOV mode and HQ mode. FOV mode has a wider view but fewer details than HQ mode. FOV mode's image processing requires raw subsampling, which scales 5.5K raw into 4K raw before feeding it to the image processing pipeline. Raw subsampling is different from line-skipping; it uses the full area (of the 16:9 portion) of the image sensor so the signal-noise-ratio is much better than line skipping. Raw subsampling is also different from pixel binning. It is an optimized filtering & sampling process which is much more advanced than the simple average mechanism of pixel binning. Raw subsampling causes some loss in the finest details. However, this is not as visible in real scenes (like aerial filming) as it is on charts. DJI looked into many solutions for implementing FOV and found that the current FOV mode is the best compromise for the Mavic 2 hardware. Please remember the Mavic 2 is an extremely complex and compact piece of hardware. The current solution represents the best possible way to enable filming using the full 1” sensor wide angle area FOV on the Mavic 2 hardware. However, you may provide us a sample video of this kind of situation and also the camera settings that you've used during this particular video. You may upload the link using google drive or dropbox for further help. Please keep us posted on the latest progress.
