The Sandisk Ultra series of SD cards are not recommended, as they are borderline in terms of writing speed, you should be buying the Extreme Pro series of Sandisk cards. But in any event, the card will have no effect whatsoever on your perceived issue of grain, it is a digital recording, and it cannot affect the quality of the video image. I looked at you two clips, the one in the forest is quite obvious, it is humungeously under-exposed, hence the grain. The one at the seaside is better, but still under-exposed. The small sensor of the Mini requires you to get the light levels up as high as you can without over-exposing.
Grain would be a result of the sensor not getting enough light and not being able to write to the card fast enough, so instead of detail it records artifacts or grain to fill in the space it can't draw data for. So that means no good for night footage haha, although the scene at the beach is underexposed also but only slightly it shouldn't have caused grain at any point.
It's either over exposed or under exposed, never perfect exposure as the lighting conditions would of blown out the entire image. May look into getting ND filters, a shame the mini doesn't come with any in the fly more kit and at the moment there's no official ND filters from DJI... |
