Question: How much time in HD video will this hold?
Document: Plenty of storage for shooting regular JPEGs. Holds a fair amount of HD video from my camera too. Works great and very reliable.
Just got a my new nikkon, and this 16g sandisk is working perfect for the past few months, I take HD video and lots of pic great.
Brought this SDcard for my Kodak Camera it stores alot of pictures and video I would buy this SD card again much for the money.
I bought this to go with my video camera and it worked great. I love how much storage it has between having to change out cards. Really makes it easy.
I received it the day of the first due date. It works fine. It holds some over 700 pictures and 30 minutes of video time.
This card works quite well in my Nikon D40. It will hold about 1,100 highest-quality JPEGs or about 500 NEF (RAW) files at a time. I have not had a problem with through about 7,000 shots. Download time is slowish, but it isn't really a problem unless you actually take 1,100 pictures at a time and import them to a computer all at once. The price is great.
never written a review for this type of item but I have been very satisfied with the memory card. No problems using it, works well and the price was right! I use this for an underwater camera and it does a great job with both videos and photos. Has enough capacity to be able to take all he photos or video I want with out holding so much I cant remember what I was using it for :)
There's not much you can say about a SanDisk digital card except that it works just fine in the Kodak Easy Share camera I bought for my granddaughter!! It arrived on time.
There really isn't much to say about SD cards. I use them to speed up my laptop, which has slowed down over time. (on some PCs, you can plug in some form of removable storage, and use it to speed up your computer.) My computer's boot up time has been shortened a lot, so I would assume this is why!
There is nothing negative I could say about this product. It was a great price. Came as shown. It has a huge amount of space (I upgraded from 4GB). Shipped very quickly.I am impressed. So far, my images load quickly on my computer. I love this size disc because my computer has a slot for it. Makes my life so much easier versus finding the cord every time.
Answer: This is a NO BRAINER.........   If you  look at the size of the video file ???   then  play the video ?????   you can figure this out....example.....video size is 40gb ----- play time is 100 min...    40/100=.4gb per min ... so 4gb = 10 min...  Got it????
