I have a couple questions regarding the memory card used with the P3P.
Shooting in 4K 30fps
Factory memory card
No filter


I took it out for a spin for the first time yesterday and I found that the video was very crisp but when I rotatated the drone the video became very blurry even during a slow rotation.  I've seen quite a few videos where similar rotation has looked very crips and clear.  Just curious if this could be attributed to the speed of the memory card?

I'm planning on going out to buy a larger one today, just curious if anybody has some specs on the best card to grab.

Thanks!

WRITE speed is governed by the Phantom, READ speed you want as fast as you can find (95Mb/s) so you can download the files to your computer. Sandisk 64 there is a UH-1 card with read speeds of 95Mb/s. Check more postings.

Below is the fastest SanDisk memory card available right now. It can write at 90MB/s.

There are some other good options here:

In general, you should look for a class 10 card that can write at least at 40MB/s. Those are the specs of the memory card that comes with the Phantom.

Short version - for now it doesn't matter how fast your card is, as long as it is rated class 10, that's as fast as the P3 is capable of writing files. Faster cards will help you transfer the data to your computer more quickly.

Personally I buy U3 rated cards because I can share them with my camera (a6000) using the SD card adapter that comes with most cards. I do recommend purchasing at least two cards so that each time you remove a card to transfer data to the computer you have a second card to place into the P3, which really helps prevent showing up at your filming your location to discover your memory card is at home.

95 Mb/s  Reads.  Check it out.....The FASTEST today. Tomorrow who knows.

The blurry picture during rotations is NOT card speed related, it is simply due to the shutter speed setting. If you leave the camera settings on auto, well then you don't have control over things like that.

DJI says the video bitrate is up to 60 Mb/sec. So that is 7.5 MB/sec. However, DJI claims a UHS class 10 card is required. However, I see no real argument to support that claim. In fact, I tested 4K video 25 Hz with an old class 4 card and guess what, no problem whatsover - no dropped frames, no lag nothing. The card I used has an average writing speed of 6 MB/sec. Now that is actually less then the average bitrate of the video file, so I think the camera even has a decent writing buffer to deal with that. In fact, I noticed the video recording did not stop at once after touching the stop button, but seemingly continued for maybe 2 seconds, probably the buffer at work.
I'd say use anything with a minimum writing speed of 8 MB/sec and you're good. There is no truth in "Class 10 or UHS-1 rating required" as the Phantom 3 specs say.

I recorded some video samples indoor, at night, in low light, on auto. Yes there was some motion blur. The same in the videos on the slow card, as it was on the Lexar class 10 card. No difference at all.

Could it be that DJI claims you need high speed cards, just to suggest the camera is so high end it can't do without?

I'm not lying. Test it yourself.

LOL.  I figure the owners of DJI probably also have money invested in SD card manufacturing.  

For more information on the SD card updates you can see https://techlish.org i have got good information from there.
