I was using a cheap SanDisk SD card in my Nikon p1000 but decided I wanted a faster card so that I could record 4K. So I bought a Lexar x1500 for around $40 or so. When it came, I put it in the camera and changed the settings to higher res. I did an interview which I paid for and when I got home to edit it, it was crap. Digital noise, blur, lost frames, etc. So I took the card out and noticed it had contacts on the edge like all SD cards, but also contacts half way up the back as well. So I wonder if the Nikon p1000 can utilize these contacts or if they are even necessary to record 4K? I have a newer SanDisk card that says A2 on it that does record in 4K properly and it does not have the additional contacts.

What is the difference between A1 and A2?
What card should I buy that will for sure do the job? Some with higher numbers cost less and I thought the Lexar would be better as it cost more, but I was wrong.

Is it necessary to pay nearly $100 for a card that works for sure? My videos are short so I only need 64GB.

Can someone explain this stuff to me, please?

Check your book. It will specify what card ratings you need.

Every few years, new ratings were needed for cards. One is the "V". A "V30" is good. Then there is the "Class". "C10" is good. The newest might be the "U". "U3" is good.

The "UHS" is "I" or "II" and it is about one or two rows of contacts. The vast majority of our cameras only have one row. The two row "II" card is supposed to act like a one row "I" card when there is only one row of contacts in the camera. Some will use the "II" cards because their computers can have a two row reader that will improve copy speeds.

My current habit is buying Sandisk Extreme V30, C10, U3, UHS 1 cards. I use them in DJI, Sony, Panasonic and Olympus cameras that shoot 4K30. One step up is the Sandisk Extreme Pro but none of my cameras can take advantage of them.

A quality 64GB card is now about $12. I used to buy only 32GB and it was enough. Now the price difference between 32, 64 and 128 is too little to matter.

From the manual it says UHS-I. Don't pay for the second contact strip.

The Nikon P1000 does not have UHS II capability and cannot use the second channel of the interface. UHS II cards will perform at about half of their stated speed in your camera.

Dumb question here, but did you format the card IN the camera. Doing that might just resolve the issue.

Not dumb at all. Yes, I did.

For 4K a V90 is called for.

bsprague Loc: Lacey, WA, USA

That is not my experience. The highest setting on my best camera at 4K is 100Mbps. Half of that works well and makes smaller files. The Sandisk Extreme card writes at 170 and is a "V30" card. The Sandisk Extreme Pro is a little more expensive and writes at 200 Mbps.

If you buy a P1000 with the kit option at B&H, the included card is a Sandisk Extreme Pro (UHS 1, V30, U3, C10, 200Mbps.)

Buying V90 cards is money spent unnecessarily.

That's good to know. The card I bought should have worked. It is rated at 150Mbps. It might just be a defective card. I should have tried it first before depending on it.

Architect1776 Loc: In my mind

If you believe that.
V90 is better for 4K.

I do believe it! I've tested it too.

I was (and am!)enthralled with with the idea of shooting 4K to get enough pixels for post processing induced effects with key frames (like pan&zoom, cropping, etc). There is also the potential of getting 8MP stills or prints from each frame.

So, I switched to a camera that could shoot 4K, take stills and was small enough for travel almost 10 years ago. (Panasonic LX100). Since then I've added a larger camera, a drone, an improved travel camera and an action camera. All shoot 4K and one will go as high as 100Mbps. (bits)

I use all "V30" cards. That rating came along for higher capacity video. "V30" means 30MBs (bytes, not bits) continuous recording. Most of my cards are Sandisk Extremes. Some are micro SD.

In almost 10 years of 4K shooting and editing, I've had never had a problem with V30 cards. Besides, the instructions for all the cameras say the same thing.

I'm not sure I would prefer Lexar over SanDisk.

bsprague Loc: Lacey, WA, USA

I read that the only problem with SD cards is when they might be counterfeit. Buy a known brand like SanDisk, Lexar, Samsung, Kingston or Transcend from a reliable source like B&H or Adorama and you will get a good card.

I don't actually know any more than rumors and a bit of personal experience. It would be nice if these sorts of things were independently evaluated.
