Phillip Bloom says in his unboxing video at around 8 minutes that 10-bit DLog-M is only available in the "4K HQ" mode, which is the cropped FOV, and that you cannot shoot 10-bit 4K with the full FOV of the sensor/lens.
Is this true? This restriction is not mentioned anywhere in the specs on DJI's website and seems like a big omission if so.
