00:00:00,520 --> 00:00:06,520
video cards they're good for you know

2
00:00:04,040 --> 00:00:11,040
anything to do with video right I mean it's it's right in the name video card

3
00:00:09,000 --> 00:00:15,640
they've got features to enhance video playback in real time they've got

4
00:00:13,440 --> 00:00:20,760
dedicated Hardware to accelerate video games and they're a necessary component

5
00:00:18,320 --> 00:00:26,960
of any system that needs to Output video to a display at all but what about video

6
00:00:24,599 --> 00:00:33,120
editing this capability has been featured prominently on the boxes of

7
00:00:29,439 --> 00:00:35,960
video cards for over a decade but do

8
00:00:33,120 --> 00:00:40,840
they actually make any bloody difference or should you just get a beefy CPU and

9
00:00:38,160 --> 00:00:47,609
Tackle your video rendering that way let's find out shall

10
00:00:50,480 --> 00:00:57,480
we the master case 5 by Cooler Master gives you the freedom to truly make your

00:00:55,120 --> 00:01:01,399
midtower PC case your own with a variety of modular parts and accessories check

12
00:00:59,519 --> 00:01:06,600
out the l in the video description to learn more let's start with a little bit

13
00:01:03,920 --> 00:01:12,600
of background on why it is that we are doing this we make videos and one of the

14
00:01:09,600 --> 00:01:14,520
most tedious and timeconsuming processes

15
00:01:12,600 --> 00:01:19,600
that slows us down aside from our servers being broken is transcoding

16
00:01:17,479 --> 00:01:24,479
footage for faster performance in Adobe Premiere a process that you can learn

17
00:01:21,400 --> 00:01:26,600
more about here and encoding our

18
00:01:24,479 --> 00:01:30,640
finished videos using the optimal resolutions and video codecs for the

19
00:01:28,640 --> 00:01:36,200
various platforms that we publish on including YouTube vessel and billybilly

20
00:01:33,560 --> 00:01:41,520
docomo when we were developing our copor workflow that GPU usage in our

21
00:01:38,840 --> 00:01:45,880
workstations was much higher than we expected with certain workloads which is

22
00:01:43,560 --> 00:01:49,240
funny because we originally thought the GTX Titan class cards in our editing

23
00:01:47,680 --> 00:01:54,799
workstations were basically a because we can thing but something we never really

24
00:01:51,799 --> 00:01:58,360
had the time to investigate was which

25
00:01:54,799 --> 00:02:00,360
video cards are best for this process we

26
00:01:58,360 --> 00:02:05,719
just stuck with what NVIDIA had provided us back when we did our whole room water

27
00:02:02,399 --> 00:02:07,920
cooling project well now we've got an

28
00:02:05,719 --> 00:02:13,520
opportunity to answer that question for the Adobe editors out there for an

29
00:02:10,560 --> 00:02:21,560
unrelated project super micro just sent us one of their super server Sy 4028 gr-

30
00:02:17,400 --> 00:02:24,000
trt servers this freaking badass of a

31
00:02:21,560 --> 00:02:30,319
machine is going to be used in a project where we run eight gaming rigs off of a

32
00:02:26,239 --> 00:02:34,400
single box with gtx980 ti amp card from

33
00:02:30,319 --> 00:02:37,400
Zotac more to come but in the meantime

34
00:02:34,400 --> 00:02:40,599
it presented an opportunity for me and

35
00:02:37,400 --> 00:02:42,280
Ed to quickly and with relative ease

36
00:02:40,599 --> 00:02:48,440
without any physical access to the machine use on raid as a virtualization

37
00:02:45,440 --> 00:02:51,000
host and then use this thing as a remote

38
00:02:48,440 --> 00:02:55,800
test bench so Ed could shut down a Windows Virtual Machine virtually swap

39
00:02:53,560 --> 00:03:01,080
the video card to any one of the ones in here turn it back on and be ready to

40
00:02:58,319 --> 00:03:06,440
rock with a new set of bench marks this led us examine how a wide cross-section

41
00:03:04,000 --> 00:03:11,920
of different video cards on both the AMD and NVIDIA side of the fence behaved in

42
00:03:08,920 --> 00:03:13,840
our typical video encoding tasks so the

43
00:03:11,920 --> 00:03:18,440
virtual machines were set up with eight core hyperthreaded virtual processors to

44
00:03:16,040 --> 00:03:24,680
represent a high-end consumer or mid-range Zeon processor and 32 gigs of

45
00:03:21,840 --> 00:03:30,040
RAM the tests were done using the 200 gig boot SSD as a source and as a Target

46
00:03:27,920 --> 00:03:34,760
and we used actual Linus media group video projects for all the scenarios

47
00:03:32,920 --> 00:03:41,200
let's start by looking at the time it takes to export a timeline containing

48
00:03:37,280 --> 00:03:43,480
mostly cfor video clips in cfor this is

49
00:03:41,200 --> 00:03:47,360
how we would normally send the project to the final export server for

50
00:03:45,280 --> 00:03:52,920
processing into h264 and the only real conclusion that

51
00:03:50,720 --> 00:03:58,599
we can draw from this is that whether you go with AMD and therefore opencl

52
00:03:56,040 --> 00:04:02,959
acceleration or NVIDIA and therefore Cuda acceleration for your video

53
00:04:00,480 --> 00:04:08,840
workstation you're going to be getting a very similar experience just make sure

54
00:04:05,840 --> 00:04:11,280
that you do have a video card as relying

55
00:04:08,840 --> 00:04:16,000
on the CPU to do this work on its own is clearly a bad idea for the next scenario

56
00:04:14,360 --> 00:04:20,519
we're looking at something that would be more applicable to most prosumer and

57
00:04:18,600 --> 00:04:26,759
professional video editors so we're taking the 1080p cfor export from the

58
00:04:23,240 --> 00:04:29,800
first test and transcoding it to 4K

59
00:04:26,759 --> 00:04:33,520
h264 no separate encoding server

60
00:04:29,800 --> 00:04:36,320
involved our GPU usage hovered around

61
00:04:33,520 --> 00:04:41,560
30% and the advantage that our video cards enjoyed over the CPU only workflow

62
00:04:38,960 --> 00:04:46,160
diminished significantly here which might lead one to the conclusion that

63
00:04:43,919 --> 00:04:50,520
which graphics card you choose doesn't matter or even that a graphics card is

64
00:04:48,680 --> 00:04:56,280
really optional if you're exporting videos directly from your editing

65
00:04:52,960 --> 00:04:59,759
workstation except that our third test

66
00:04:56,280 --> 00:05:03,800
using chroma keed copor 4K footage and

67
00:04:59,759 --> 00:05:06,680
exporting to 1080p cinor showed us what

68
00:05:03,800 --> 00:05:12,240
we were finally looking for the scenario in which a powerful video card

69
00:05:09,120 --> 00:05:15,680
demonstrates not just better performance

70
00:05:12,240 --> 00:05:18,520
against pure CPU encoding but also

71
00:05:15,680 --> 00:05:24,400
lesser video cards so the beefiest gaming GPU in this case the

72
00:05:20,960 --> 00:05:26,960
gtx980ti in the system comes out on top

73
00:05:24,400 --> 00:05:31,720
with the Lesser cards performing about as much worse as you would expect given

74
00:05:29,400 --> 00:05:36,800
their overall horsepower and this would be applicable not just to chroma key

75
00:05:34,479 --> 00:05:42,240
green screen footage but also to any project with other effects like lumry

76
00:05:39,000 --> 00:05:44,840
color uh or warp stabilizer which leads

77
00:05:42,240 --> 00:05:51,440
us then to a really interesting final conclusion here AMD versus NVIDIA in

78
00:05:48,560 --> 00:05:56,840
this case doesn't seem to matter much the 970 and the r9290 which is about

79
00:05:54,360 --> 00:06:01,840
equivalent to its 300 series replacement are similar enough across the board that

80
00:05:59,479 --> 00:06:06,759
I I couldn't recommend one brand over the other for editing an Adobe Premiere

81
00:06:04,400 --> 00:06:12,240
with that said that might not be the case if you use other tools but the

82
00:06:09,919 --> 00:06:17,720
takeaway here then is that for video editing and Adobe Premiere you should

83
00:06:14,720 --> 00:06:21,319
get a GPU even if it's just a mainstream

84
00:06:17,720 --> 00:06:23,160
model and that much like for gaming once

85
00:06:21,319 --> 00:06:27,800
you get into the performance and Enthusiast product range you are getting

86
00:06:25,520 --> 00:06:33,280
diminishing returns for the money you spend neat

87
00:06:30,520 --> 00:06:39,520
speaking of which this is pretty cool this is a brand new sponsor for us Blue

88
00:06:36,599 --> 00:06:44,520
Apron allows you to create delicious chef-designed recipes at home they

89
00:06:42,440 --> 00:06:48,199

00:06:46,400 --> 00:06:52,720
exactly the right proportions so no trips to the grocery store are required

91
00:06:50,440 --> 00:06:57,800
and there is no waste from unused ingredients they offer two types of

92
00:06:54,880 --> 00:07:02,000
plans the two-person plan and the family plan the recipes are delivered in a

93
00:06:59,919 --> 00:07:05,560
refrigerated box so the ingredients stay fresh even if you're not at home when

94
00:07:03,479 --> 00:07:09,800
your package arrives and they offer a large selection of recipes and are

95
00:07:07,840 --> 00:07:14,720
always adding new dishes to the menu every week there is no commitment you

96
00:07:12,240 --> 00:07:20,479
can skip or cancel the service at any time and each menu is between 500 to 700

97
00:07:18,160 --> 00:07:24,680
calories per person the ingredients are sourced from quality suppliers and

98
00:07:22,560 --> 00:07:30,360
Artisans and all meals can be prepared in 40 minutes or less so blue apron lets

99
00:07:28,440 --> 00:07:34,720
you learn to make new new recipes and Cuisines so you can get out of your

100
00:07:32,199 --> 00:07:38,879
dinner rut of making the same old dishes or relying on takeout and the best part

101
00:07:37,280 --> 00:07:43,400
is that blue apron is available Nationwide in the US and the first 250
