00:00:00.280 --> 00:00:05.600
are we ready yeah are you sure you're ready for this actually hold on a second

00:00:03.840 --> 00:00:09.440
let me just let me just fix the uh well no you don't it's it's already I I set

00:00:07.240 --> 00:00:15.559
it up before we did anything so you don't have to change oh right this one

00:00:11.880 --> 00:00:18.000
no no oh oh oh oh okay you know what

00:00:15.559 --> 00:00:21.880
just for forget it I'll just I'll host it you you operate the camera let's just

00:00:20.519 --> 00:00:27.960
go back to the normal way doing things what's uh what's this video about again SD

00:00:24.599 --> 00:00:28.960
cards no right now I remember why you're

00:00:27.960 --> 00:00:32.599
doing this okay let's

00:00:36.559 --> 00:00:43.399
go cooler Masters case mod World Series is your opportunity to show off your

00:00:41.360 --> 00:00:48.559
modding skills and win great prizes entries close February 7th 2015 click

00:00:46.079 --> 00:00:53.840
now to learn more hey guys what's up Brandon here so SD cards they're boring

00:00:51.320 --> 00:00:57.600
right line us obviously thought so but they're way more exciting than you

00:00:55.239 --> 00:00:57.600
probably

00:00:58.920 --> 00:01:01.920
realize

00:01:19.960 --> 00:01:26.000
mine's changed no okay fine but onto my actual

00:01:24.439 --> 00:01:29.960
point SD cards are one of the most important things I personally use on a

00:01:28.119 --> 00:01:33.560
day-to-day basis and while I get some black for the number of them I've

00:01:31.320 --> 00:01:36.560
collected over the years i' if I didn't have them I wouldn't be able to do my

00:01:35.000 --> 00:01:41.880
job so learning about them for me was worthwhile investment and I'm going to share some of that knowledge with you

00:01:39.200 --> 00:01:44.520
guys to start with we need to demystify some of the confusing numbers and

00:01:43.040 --> 00:01:51.560
letters associated with the different classes of SD cards cuz there's a lot of

00:01:46.960 --> 00:01:54.320
them class 4 class 6 class 10 UHS 1 UHS

00:01:51.560 --> 00:01:58.079
3 does your brain hurt yet let's break it down each of these numbered classes

00:01:56.320 --> 00:02:03.719
represents an increase in the minimum right speed in megabytes that a card can

00:01:59.840 --> 00:02:06.119
can handle with UHS 1 and UHS 3 denoting

00:02:03.719 --> 00:02:09.520
the most recent Ultra high-speed cards recently there's been a lot of hype

00:02:07.520 --> 00:02:14.440
about consumer devices that can shoot 4K video and 4K support and SD cards which

00:02:12.200 --> 00:02:18.760
is why the UHS 3 standard was introduced and is the focus of our video today does

00:02:16.400 --> 00:02:22.760
it matter do I need a UHS 3 card to shoot 4K video well I wanted to know and

00:02:21.200 --> 00:02:28.400
I also wanted more SD cards to play with so I asked lus if I could put in a few sample requests and he said oh yeah I

00:02:26.920 --> 00:02:32.480
guess as long as you do the benchmarking on them so I did I ended up with nine

00:02:30.959 --> 00:02:38.040
cards in total and I ran a number of different benchmarks including Crystal dismark as well as some real world

00:02:35.360 --> 00:02:44.040
testing on a Canon 60 DSLR and our lovely Panasonic GH4 which is a 4K 30fps

00:02:41.040 --> 00:02:45.360
capable camera these two cameras will be

00:02:44.040 --> 00:02:49.480
amongst the most demanding cameras that can run on SD cards with the higher

00:02:47.239 --> 00:02:54.280
performance options like our fs700 requiring SSD or proprietary media

00:02:52.120 --> 00:02:58.200
something that you can see in this video here so how do we do well the numbers

00:02:56.840 --> 00:03:01.800
speak for themselves most cards performed in Crystal dismark as expected

00:03:00.120 --> 00:03:05.480
within the range of their rating benchmarking was done in an MSI gs70

00:03:04.120 --> 00:03:08.799
with the built-in card reader which I used out of convenience when I observed

00:03:07.239 --> 00:03:13.799
its results were pretty much identical to the one we were getting with the Standalone and Kingston USB 3 reader now

00:03:12.040 --> 00:03:17.360
crystal dismark is only a synthetic benchmarking software and those numbers

00:03:15.400 --> 00:03:20.599
are not necessarily representative of real world performance where other

00:03:19.000 --> 00:03:25.319
factors like cam former can come into play so on to our real world tests for

00:03:23.040 --> 00:03:29.920
the GH4 test I shot multiple 30 second and 1 minute Clips on each card the

00:03:27.400 --> 00:03:34.519
first clip is in 4k at 30 FPS shooting at a bit rate of 100 megabits per second

00:03:32.200 --> 00:03:38.640
the second clip is in 1080P at 30 FPS shooting in a very stressful bit rate of

00:03:36.519 --> 00:03:41.239
200 megabits per second I was astonished to discover that every single card in

00:03:39.959 --> 00:03:45.959
our Roundup worked perfectly with the GH4 I did a combination of static shots

00:03:44.000 --> 00:03:48.920
with a slow pan and tilt with each card when playing back the footage in

00:03:47.159 --> 00:03:53.760
Premiere none of them had any drop frames moving on to the Canon 6D test I

00:03:51.599 --> 00:03:57.599
shot 30 raw Stills per card using the burst shooting mode here are my camera

00:03:55.560 --> 00:04:01.120
settings to give a visual representation of this I recorded audio of the shutter

00:03:59.159 --> 00:04:05.360
during the T test the audio bunches that you see here are the 18 raw Stills that

00:04:03.519 --> 00:04:08.680
can be taken within the camera's buffer and every Spike after that is the

00:04:06.959 --> 00:04:12.439
following picture leading up to a total of 30 to my surprise the Sony card came

00:04:10.760 --> 00:04:16.639
in the slowest in this test even with its higher read right speed compared to

00:04:14.159 --> 00:04:20.000
the lower-end ad and Kingston cards with sandis cards taking the win with very

00:04:18.479 --> 00:04:25.000
solid performance in the shortest amount of time so conclusion time is One SD

00:04:22.560 --> 00:04:29.280
card really better than another yes is it absolutely necessary to have a UHS 3

00:04:26.880 --> 00:04:32.199
card for 4K video the short answer seems to be no

00:04:30.360 --> 00:04:35.840
for now while only half the cards in this test are classified as UHS one they

00:04:34.360 --> 00:04:39.960
all manage to have high enough speeds to handle the 100 to 200 megabit bit rates

00:04:37.680 --> 00:04:42.440
of the G4S recording modes but in future cameras we might see higher supported

00:04:41.280 --> 00:04:47.320
bit rates and you'll need to be careful to get the card that can handle the right speeds to match it should be noted

00:04:45.919 --> 00:04:51.960
that if you're shopping that read speeds are far less important since they'll only come into play when ingesting

00:04:50.400 --> 00:04:55.639
footage that you've already shot something that is rarely the bottleneck

00:04:53.400 --> 00:04:58.520
with our workflow so thanks for watching let me know what you guys thought of the

00:04:56.880 --> 00:05:02.880
video If you enjoyed it if you want to see me talk about tech on the other side

00:05:00.320 --> 00:05:07.120
of the lens more lonus said he would pay for me to go to NAB this year so please

00:05:05.400 --> 00:05:12.560
leave lots of honest feedback under the video I really want to go to NB so even

00:05:09.199 --> 00:05:15.080
if you hated it you probably should tell

00:05:12.560 --> 00:05:18.840
him that you loved it and all right all right all right all right all right all

00:05:16.360 --> 00:05:23.240
right all right all right yeah just getting pathetic over there so guys like

00:05:21.440 --> 00:05:27.199
you did say though please do leave comments if you enjoyed Brandon's first

00:05:25.240 --> 00:05:30.880
on camera appearance ever he really is our resident expert when it comes to

00:05:28.680 --> 00:05:34.360
this stuff and uh we really appreciate you guys watching this video and we also

00:05:32.680 --> 00:05:39.720
really appreciate our sponsor Dollar Shave Club Dollar Shave Club is the way

currency of these different regions now they don't just have razors they've also

00:06:03.039 --> 00:06:08.479
got shaving cream they've got well shouldn't say cream because it's more of

00:06:06.639 --> 00:06:11.800
a butter it goes on clear so you can see what you're doing they've got their

00:06:09.759 --> 00:06:15.599
aftershave and they've got their and this is always a fan favorite one WIP

00:06:20.639 --> 00:06:26.880
start shaving time and shaving money it's one of those things shaving time

00:06:25.000 --> 00:06:30.720
and shaving money I get Flack from you guys when I do the shave time shave

00:06:28.680 --> 00:06:34.000
money thing and when I do save time save money I feel kind of bad cuz their
