00:00:00,199 --> 00:00:06,200
welcome to another episode of how to here on lineus Tech tips today we'll be

2
00:00:04,400 --> 00:00:11,080
doing something that's a little bit more complicated but we'll give you a truly

3
00:00:08,840 --> 00:00:15,040
awesome results if it is done correctly what I'm talking about is streaming

4
00:00:12,400 --> 00:00:19,520
mixed reality footage what's that well if you have a VR headset such as the HTC

5
00:00:17,560 --> 00:00:23,400
Vive that we have here in the office you can actually stream footage of yourself

6
00:00:21,400 --> 00:00:28,080
doing things in a virtual game environment so to the viewer it will

7
00:00:25,720 --> 00:00:33,079
look like you're walking around in a Fantastical World instead of just your

8
00:00:30,599 --> 00:00:41,519
living room it does this by transposing the in-game environment onto a green

9
00:00:43,800 --> 00:00:51,480
screen cooler Master's new master keys Pro L and pro s keyboards feature 16.7

10
00:00:49,239 --> 00:00:55,440
million color RGB back lighting genuine Cherry MX switches and an

11
00:00:53,039 --> 00:00:59,079
industry-leading ARM cortex processor learn more at the link in the video

12
00:00:56,879 --> 00:01:03,760
description today we'll be showing you how to do this in fantastic Contraption

13
00:01:01,359 --> 00:01:07,560
a game from Northway games we'd also like to take this opportunity to give

14
00:01:05,199 --> 00:01:12,159
Northway a shout out as we base this guide on the mixed reality information

15
00:01:10,000 --> 00:01:15,880
that they provided on their website you can find a link in the video description

16
00:01:13,840 --> 00:01:21,079
down below all you need to get started other than a VR headset and a gaming rig

17
00:01:18,200 --> 00:01:25,759
is a green screen an HDMI camcorder and either an internal or external capture

18
00:01:23,200 --> 00:01:30,600
card with an HDMI port we'll be using an a media live gamer portable in our

19
00:01:28,320 --> 00:01:35,159
demonstration today also make sure you have an HDMI cord long enough to reach

20
00:01:32,759 --> 00:01:38,520
from your capture card to your camcorder as this will allow you to move your

21
00:01:36,640 --> 00:01:43,200
camcorder to different places around the room so that you can adjust how your

22
00:01:40,720 --> 00:01:46,640
stream will end up looking this is especially important if you're getting a

23
00:01:44,640 --> 00:01:50,360
friend to act as a camera person instead of just putting your camera on a tripod

24
00:01:48,640 --> 00:01:55,240
to get started go ahead and set up your HTC Vive according to the manufacturer's

25
00:01:53,000 --> 00:01:58,840
instructions then get your capture card installed although external capture

26
00:01:57,320 --> 00:02:03,719
cards are generally connected with a simple USB cord there are also internal

27
00:02:01,560 --> 00:02:08,319
capture cards that slot into a PCI Express 1X slot if you'd like to keep

28
00:02:06,479 --> 00:02:12,160
things a little bit tidier after you've gotten your Vive and your capture card

29
00:02:09,959 --> 00:02:16,400
ready go ahead and start setting up your green screen green screens come in lots

30
00:02:14,280 --> 00:02:20,920
of different sizes so you want to get something that can surround your play

31
00:02:18,200 --> 00:02:24,560
area on at least two sides as well as something to cover the floor green

32
00:02:22,840 --> 00:02:27,640
screen fabric actually works pretty well for this and it's not that bad to adjust

33
00:02:26,360 --> 00:02:32,040
but you will need something to hang it on make sure your lighting is adequate

34
00:02:29,519 --> 00:02:36,280
as well well generally bright light is better as it will allow your camera and

35
00:02:34,280 --> 00:02:39,760
your software to more easily separate the green screen from everything else

36
00:02:38,720 --> 00:02:45,959
next you'll want to set up your camcorder if you don't have one don't worry about buying something super

37
00:02:43,640 --> 00:02:51,280
expensive as realistic effects can be achieved with many fairly inexpensive

38
00:02:48,159 --> 00:02:52,800
models such as a Sony handicam just make

39
00:02:51,280 --> 00:02:56,680
sure you aren't using something like a webcam or a phone camera as it probably

40
00:02:55,120 --> 00:03:00,200
won't be good enough place your camera in a spot that will capture as much of

41
00:02:58,599 --> 00:03:04,959
the play area as possible possible without placing areas outside of your

42
00:03:02,599 --> 00:03:08,440
green screen setup in the frame you don't want to have your stream or

43
00:03:06,720 --> 00:03:14,120
recording ruined because it looks like some far away world is directly bordered

44
00:03:11,280 --> 00:03:18,360
by your living room couch connect your camera to your capture card's HDMI input

45
00:03:16,519 --> 00:03:23,360
and you're ready to go at least on the hardware side next is the software setup

46
00:03:21,200 --> 00:03:27,120
not all games support mixed reality but the Vive does have a number of games in

47
00:03:25,000 --> 00:03:32,159
its library that do such as fantastic Contraption which has a setting that

48
00:03:29,360 --> 00:03:36,959
enables multiple virtual cameras within the game this allows your capture

49
00:03:34,120 --> 00:03:42,280
software to use depth information to combine the VR graphics and the feed

50
00:03:39,280 --> 00:03:44,360
from your real life camcorder accurately

51
00:03:42,280 --> 00:03:49,080
just open the settings menu in game make sure toggle depth camera is checked and

52
00:03:46,760 --> 00:03:53,120
enter all zeros in the field labeled foreground color key you'll need to set

53
00:03:51,280 --> 00:03:57,760
up your capture software next which can be a little bit more complicated as it

54
00:03:55,400 --> 00:04:02,599
needs to combine three layers the game foreground The Game background and the

55
00:04:00,239 --> 00:04:08,959
feed from your camcorder we're going to use open broadcasting software or OBS

56
00:04:06,560 --> 00:04:14,519
download install it open it then hit the plus sign underneath sources and pick

57
00:04:11,560 --> 00:04:19,600
window capture name this layer VR background and select fantastic

58
00:04:16,680 --> 00:04:23,240
Contraption turn off cursor capture then enter the correct streaming resolution

59
00:04:21,519 --> 00:04:28,120
for fantastic Contraption since the depth camera option splits the screen

60
00:04:25,320 --> 00:04:31,120
into four quadrants you can only stream at one quarter of your computer

61
00:04:29,680 --> 00:04:37,080
computer's resolution so if you're running a monitor at 1080p you'll need

62
00:04:33,600 --> 00:04:39,039
to enter a resolution of 960x 540 but if

63
00:04:37,080 --> 00:04:43,800
you have a 4K display you can stream at 1920 by 1080 once you've done this make

64
00:04:41,840 --> 00:04:49,120
sure that you grab the corner of the layer and expand it to fill the entire

65
00:04:45,880 --> 00:04:51,720
canvas next under sources add the webcam

66
00:04:49,120 --> 00:04:55,800
layer by picking video capture device and then name it camcorder or honestly

67
00:04:54,120 --> 00:04:59,960
whatever you'd like fill the whole cameras with the camera layer like you

68
00:04:57,400 --> 00:05:04,520
did in the previous step then select color key under effects filters so that

69
00:05:02,840 --> 00:05:09,240
your computer will process the green screen properly play with the similarity

70
00:05:07,360 --> 00:05:13,600
and smoothness settings until things look good the last layer is the VR

71
00:05:11,360 --> 00:05:17,720
foreground which you should now add by following a similar procedure to the

72
00:05:15,360 --> 00:05:23,400
background however this time deselect the capture any full screen application

73
00:05:20,000 --> 00:05:25,800
option and select allow transparency

74
00:05:23,400 --> 00:05:31,160
make sure again to deselect capture cursor to enter a proper resolution and

75
00:05:29,240 --> 00:05:35,039
to expand the layer to fill up the canvas the last step is to sync up your

76
00:05:33,280 --> 00:05:39,680
camcorder with what's going on in the game make sure both the game and OBS are

77
00:05:37,479 --> 00:05:45,759
open then adjust the virtual camera with the w a s d q and E keys this is a lot

78
00:05:43,919 --> 00:05:50,840
easier if you can get a friend to stand in the play area with the controllers in

79
00:05:48,199 --> 00:05:55,759
hand so you'll have a point of reference but this can be done by just placing the

80
00:05:53,080 --> 00:05:59,759
controllers on something as well this will allow you to match up the in-game

81
00:05:57,840 --> 00:06:04,000
camera system and your camcorder precisely so that the stream will look

82
00:06:01,680 --> 00:06:09,039
realistic also be sure to adjust the feel the view settings by dragging the

83
00:06:06,280 --> 00:06:13,479
third person fov slider in the in-game settings until the in-game virtual

84
00:06:11,120 --> 00:06:17,440
controllers match up with wherever your friend is holding the real ones however

85
00:06:15,680 --> 00:06:21,199
if you want to use a moving camera you can do this by taping a third Vive

86
00:06:19,160 --> 00:06:25,800
controller to your camcorder which will cause the game to track its position

87
00:06:23,440 --> 00:06:30,800
making for an even more interesting visual presentation just select handheld

88
00:06:28,639 --> 00:06:35,440
mode in the in-game settings menu and sync the cameras using the previous

89
00:06:32,599 --> 00:06:38,840
steps so after you've done all of this you're finally ready to stream or record

90
00:06:37,599 --> 00:06:42,280
or whatever you want to do although there are a lot of steps involved the

91
00:06:40,759 --> 00:06:47,000
result should make it look like you're firmly in the middle of a virtual world

92
00:06:44,680 --> 00:06:50,199
it won't look exactly James Cameron like but you will be able to give your

93
00:06:48,120 --> 00:06:53,240
viewers a really cool experience that can set your channel apart don't stop

94
00:06:52,000 --> 00:06:56,560
don't stop don't stop oh my God I just killed the cat

95
