Choosing the Best SD Card for Video – Understanding All the Numbers and Symbols on SD Memory Cards


All right, you have your camera, you have
your lenses; but now you need something to record on. So let’s talk memory cards. Hey everyone, Camber here back with you
in Mississippi, and today we were talking about which memory cards are best for
video; and if you’re new here, this channel is all about teaching you how to
use your camera to make good films so if that’s you, consider subscribing. Now
there are many different types of memory cards. You have SD cards, Compact Flash,
Micro SD, CFast cards. So what’s the difference? Well, SD cards and Micro SD
cards are basically the same except SD cards are used in more consumer level
cameras whereas Micro SD cards are used in smaller cameras like GoPros or in
drones. Compact Flash cards are even faster and are used in more expensive
cameras like the 5D Mark 4; whereas CFast cards are some of the fastest you
can get and are used in more pro level DSLRs and cinema cameras. However, since
most cameras have ports for SD cards, we’re going to use that for our example.
Now as far as hardware is concerned, the only difference between SDHC and SDXC
cards is different filing systems which result in higher memory capacities. The
SDHC cards can hold up to 32 gigabytes whereas the SDXC cards can hold up to 2
terabytes; although you won’t find 2 terabytes out on the market yet. So the
first thing we’re gonna look at on these cards is the number on the top left
which is the maximum read speed of the card, but before we do we need to
understand a few things first. So, 8 bits equals 1 byte, and therefore 8 megabits
equals 1 megabyte. Megabits little b, megabytes big B. It’s important to know
the difference when we get into understanding read and write speeds
because people often see that their camera cords at 100 megabits per
second, little b, and think, “Oh, I need a card that records at a hundred megabytes
per second.” Big B. When actually 100 megabits per second equates to 12.5
megabytes per second. Now manufacturers don’t always advertise their write
speeds so unless the card’s write speed is explicitly stated, then any number
that you see in the top left of your memory card is going to be
card’s maximum achievable read speed. And this maximum achievable read speed comes
more into play for photography because when you start doing this… the maximum
achievable speed of the card will allow you to take more shots without having
buffering issues. But in video we care about sustained speeds because if the
sustained speed drops below the video’s bitrate, you’ll start getting dropped
frames in your video. So the next number we’ll look at represents the memory
capacity of the card, which in this case is 64 gigabytes. And what size card
you’ll need really depends on how much you plan on shooting at once. For example,
if you’re gonna be shooting a full wedding at a hundred megabits per second,
you’ll want a larger capacity card because you’ll fill up a 32 gigabyte
card at that rate in about 35 minutes. Another thing to consider is spreading
your footage among multiple cards so that if you do have a memory card
failure you won’t lose all of your footage. I like to just use one large
card so I’m not switching out cards and don’t risk losing one; however, I haven’t
experienced any memory card failure yet. The rest of the numbers you see on the
right side of the card are various ways of representing the speed class rating
of that card. The letter C with a 2, 4, 6, or 10 enclosed within it represents a
minimum sustained write speed of 2 megabytes per second for a class 2, 4
megabytes per second for a class 4, and so on and so on. However, it’s important
to note that this is the minimum rate, not necessarily the actual rate. And then
you have a U with a 1 or a 3 inside of it, and this represents a minimum sustained
write speed with U1 being 10 megabytes per second, and U3 never slower than 30
megabytes per second. So U1 is identical to class 10 in that both of them are
certified to never write slower than 10 megabytes per second; however, the
difference being that the U card is designed for SD cards that use a UHS 1
or a UHS 2 bus. Non-UHS cards max out at 25 megabytes per second, UHS-1 cards
max out at 104 megabytes per second, and UHS-2 cards max out at 312
megabytes per second. The UHS-2 cards have a second row pins that allows them
to achieve this speed, but if your device doesn’t have
the second row of pins, the card will revert to UHS-1 speeds. There’s also a V
speed that’s being added to memory cards now, and the SD Association created these
video speed class ratings in order to identify which cards are capable of 8k,
4k, 360, or 3D video. The V speed is similar to the U speeds in that it
represents the minimum sustained speed in megabytes per second that the card
can handle. Now, not all cameras are compatible with these higher speed class
ratings so you’ll want to get into your manual or look up online and see which
cards are compatible with your camera. 4K is becoming the new standard, and camera
specs are increasing rapidly. I don’t like having to upgrade things like
memory cards so I like to buy the best I can possibly get so that I’ll be able to
support future larger video formats without having to buy more support
equipment. I have links down below for what I use for my HD and 4k video, and I
suggest getting the fastest card that’s compatible with your camera so that you
never have any issues with dropped frames in your videos. And that’s all I
have for memory cards so if you made it this far, hit that thumbs up and let me know down below if you have any more questions
about memory cards. Go ahead and subscribe if you haven’t and remember
that the only way to get better at something is to practice. So get out
there and film something. See you soon.

  14. You said drone, what's a drone? Did you mean Quadcopters. What assures you 'drone' is a name? You been listening to too many ignorant, poorly educated dunces lately? Okay, then how did 'drone' become a name, a machine, a rc model, a military pilotless aircraft and what ever else every ignorant Tom, Dick and Harry think 'drone' is a name? If you and most other poorly educated illiterates think that 'drone' s a name, what about it's present and past participles, 'droning' and 'droned', its plural – 'drones' and all its definitions, are these also names? Can you call whatever you call a drone a Droning or a Droned? Can you say, "Let's go to fly a Droning", or "I bought a Droned today", can you say that? No. Why not, is it because these are words? So, 'droning' and 'droned', its plural 'drones' and its definitions are words, right? And 'drone' is not a word, is it? It's a name… is it? Really? Unbelievable at how these pathetic, low IQ stooges, these poorly educated dunces worldwide can think that they are educated, yet they're talking complete shit on drone this and drone that without thinking or considering once, that the word 'drone" is not a name, it's a word used in sentences and conversation to describe, indicate or point out a continuous loud sound and cannot be used as a name. But, you see? The ignorant retards haven't got a clue on what bullshit they're talking about, partly because years of drugs and binge drinking, artificial sweeteners in drinks and preservative in foods have destroyed their brain neurons and then they develop a symptom called MCI (Mild Cognitive Impairment), which is the stage between the expected cognitive decline of normal aging and the more serious decline of dementia. It can involve problems with memory, language, speech, thinking, reason, knowledge and judgment that are greater than normal age-related changes. As a result to this impairment from generation upon generation of drugs taking and other poisons, the brain neurons are damaged and signals sent from one cell and another is interrupted and has to be by-passed to whatever neurons are the closet to the others. This, in turn, slows the speed of signalling one another, resulting in… you guessed it, delays in response from thinking, responding, judging and memorize whatever the brains have been able to scramble in a split second to send pulses to the rest of the body, from speech to movement, from memorizing and acting precisely – on a normal level of intelligence. When someone has difficulty in remembering words that another ignorant, low IQ illiterates says, the person with MCI thinks that is the correct words, the correct sentence and, in no time they say the same thing or do the same actions or movements, like the sheep. This is how and why every ignorant, poorly educated dunce has spread this bullshit 'drone' worldwide like the plague, and they are adamant in spreading it further around that 'drone' means this and that, blah blah blah, stooges all the way, I'd say. Go on, attack me with 'drone' means this and that, show me how intelligent you are. All you had to say was, Quadcopter, less the bullshit and senseless 'drone'. And if you think a Quadcopter is a 'drone', how can a military aircraft also be a 'drone', a rc model plane, a bee, a person… fuck! How can a word be all this bullshit? Do yourself a favor, go back to school and learn the definition of 'drone', or seek medical treatment because your brains aren't functioning properly. You can be sure you are a MCI sufferer going towards a more advanced stage called ANCD (Advanced Neuro-Cognitive Disorder. Sit and think for a few minutes on how the fuck did this 'drone' word become a name machine, model, aircraft, etc., when all it means is, a continuous humming sound? No wonder YouTube is becoming a place where they post videos with shit titles and poor English. And then the sheep follow other uneducated sheep and do the same, regardless of whether the titles and comments are of proper grammar. But, what's the use being concerned about it now that there are millions of ignorant poorly educated illiterates who are already droned in their sick heads? They probably have mashed potatoes or scrambled eggs as brains, hardly worth using them for cognitive thinking, right? Stay off the drugs for Chrissake.

  15. Can someone help
    I have a Canon EOS Rebel SL2,
    Will this card work for 1080p 60fps? https://www.amazon.ca/dp/B07H42L4TJ/ref=cm_sw_r_cp_apa_i_t4TGDbTNYFQCD

  16. What a great video. I just purchased a Hero 7 Black. It came with a crappy card so now I'm trying to decide what would work best. I don't mind spending a little more. I would rather buy once cry once. Would you recommend the SanDisk Extreme, the Extreme Pro, or something else?

  17. Hello, I'm going to shoot a video on my Sony A6000 at 60fps and edit the footage in my super old Acer Timeline X (2011). Do you think I should get the Sandisk Extreme or Sandisk Ultra? Thanks!

  18. Just got an Olympus TG 6 & want to shoot photos and video (mostly underwater). What do you think would be the best sd card? Thank you!

  19. Hi Camber, first I just wanted to say thank you so much for the informative upload. Quick question…. Im starting a podcast and was just curious, would the best Micro SD cards for video work just the same if you are just recording audio? Reason I ask is cause I eventually would like to record video podcast and was hoping to use the same brand for both. Any advice will be highly appreciated.

  20. Hi and thanks for the info. What memory card will last the longest with the nine in Lorex monitor for security cameras? I am always having to replace them because they will not record anymore.
