A:AnswerI am using the card for a 4K video camera and it seems to work fine. I have an iPhone and so don't have a smart phone application for the SD card.
I don't know enough about other smart phones to give advice.
A:AnswerI am not a Technical Professional. My opinion is most important is your cameras processing and their writing speeds. The cards running at 90 mbps would give a high quality result and the shortage of 10 would be hard to visualize.
A:AnswerIt will work as long as you have a SD card slot. However if any or your video file is greater 4gb, make sure you format the card in exfat in order to support file size greater than 4gb. Good luck!
A:AnswerI'm a canon guy however if Nixon 5600 can take the SD card it will work in it and any camera that does take this type of card I have these cards in 3 different canons a power shot a to and a t6i and have no problem it is nice not to have to see orly about new cards for a month or 2 for me I'm sure depending on the size frame you shoot in you will not worry about space for a while
