1
00:00:10,520 --> 00:00:15,680
With our drone up in the air,  we can easily capture
 stunning aerial imagery

2
00:00:15,680 --> 00:00:18,440
that would not be possible
 from the ground, 

3
00:00:18,440 --> 00:00:21,960
you will see on your controller
 that we have two shoulder buttons.

4
00:00:21,960 --> 00:00:24,120
One is to start and stop video

5
00:00:24,120 --> 00:00:30,160
recording and the other that acts
 as a shutter button for the stills camera.

6
00:00:30,160 --> 00:00:35,360
By default, your drone will be set
 in automatic mode that takes all the worry

7
00:00:35,360 --> 00:00:38,760
of applying the correct settings
 out of your hands.

8
00:00:38,760 --> 00:00:41,120
To get the most out of your drone however,

9
00:00:41,120 --> 00:00:44,320
we can control a variety
 of the settings ourselves

10
00:00:44,320 --> 00:00:48,320
that will affect your video
 and photos in different ways.

11
00:00:48,320 --> 00:00:53,680
We can access all of these settings
 in the DJI Go 4 app on our smart device.

12
00:00:53,680 --> 00:00:56,480
So let's dive in and take a look. 

13
00:00:56,480 --> 00:01:00,680
Starting with frame
 rates, fps of frames per second.

14
00:01:00,680 --> 00:01:03,080
These indicate how many still images

15
00:01:03,080 --> 00:01:07,160
or frames are recorded
 in each second of footage.

16
00:01:07,160 --> 00:01:11,280
These are then played back in sequence
 to create a moving image,

17
00:01:11,280 --> 00:01:17,280
with the UK standard frame rate for playback been issued at 25 frames per second.

18
00:01:17,280 --> 00:01:20,960
By using higher frame
 rates, this allows us to create smooth,

19
00:01:20,960 --> 00:01:23,640
slow motion footage in post-production.

20
00:01:23,640 --> 00:01:27,320
For example, if you want to slow
 your footage down by 50 percent.

21
00:01:27,320 --> 00:01:32,960
Simply shoot at twice the standard
 frame rate, 50 frames per second.

22
00:01:32,960 --> 00:01:37,240
Some cameras allow you to shoot up to 120
 frames per second, which can create

23
00:01:37,240 --> 00:01:39,960
some extremely slow motion effects.

24
00:01:39,960 --> 00:01:45,360
Resolution: This is the size
 if the image of video file in pixels,

25
00:01:45,360 --> 00:01:51,120
you'll be familiar with HD 1920
 x 1080 and 4K. In photography.

26
00:01:51,120 --> 00:01:54,120
this is measured in megapixels.

27
00:01:54,120 --> 00:01:58,400
The higher the resolution, the more detail
 will be in your video and photos.

28
00:01:58,400 --> 00:02:00,320
If you're editing on a HD timeline, 

29
00:02:00,320 --> 00:02:04,880
but shoots in 4K,
 you'll be able to reframe your shots

30
00:02:04,880 --> 00:02:09,560
and use multiple parts of the image
 throughout the video if necessary.

31
00:02:09,560 --> 00:02:13,440
Resolution doesn't always mean
 your image or videowill be sharper.

32
00:02:13,440 --> 00:02:17,120
This all depends on
 how the camera sensor works.

33
00:02:17,120 --> 00:02:20,080
Exposure refers to how much light
 is hitting the cameras

34
00:02:20,080 --> 00:02:23,760
sensor and determines
 how light or dark your image is.

35
00:02:23,760 --> 00:02:27,440
How well exposed your image is controlled
 by three settings.

36
00:02:27,440 --> 00:02:30,560
Collectively known
 as the exposure triangle.

37
00:02:30,560 --> 00:02:34,000
These are aperture shutter speed and ISO.

38
00:02:34,000 --> 00:02:36,240
The aperture determines

39
00:02:36,240 --> 00:02:40,040
how wide the opening is behind
 your camera's lens and controls

40
00:02:40,040 --> 00:02:42,640
how much light is hit
 in the camera sensor,

41
00:02:42,640 --> 00:02:47,120
which can play a big part
 in how the image looks and feels.

42
00:02:47,120 --> 00:02:51,520
Aperture is measured in F stops
 and the lower the F number

43
00:02:51,520 --> 00:02:54,440
the more light is allowed
 to come into the camera.

44
00:02:54,440 --> 00:02:58,440
With higher the F number, the less amounts
 of light is coming through.

45
00:02:58,440 --> 00:03:01,440
Shutter speed: In photography,

46
00:03:01,440 --> 00:03:05,360
shutter speed is the duration of time
 the sensor is exposed to light

47
00:03:05,360 --> 00:03:08,280
and can massively affect
 how the movement is captured.

48
00:03:08,280 --> 00:03:12,480
A fast shutter speed
 will freeze your subjects in time,

49
00:03:12,480 --> 00:03:14,240
whilst a slow shutter speed 

50
00:03:14,240 --> 00:03:20,040
can be used creatively
 to show motion blur and light trails.

51
00:03:20,040 --> 00:03:22,440
For video, the general rule of thumb

52
00:03:22,440 --> 00:03:26,440
is that the shutter speed
 should be twice as fast as the frame rate.

53
00:03:26,440 --> 00:03:28,800
If you're shooting
 at twenty five frames per second.

54
00:03:28,800 --> 00:03:32,120
Set the shutter speed to one
 fiftieth of a second

55
00:03:32,120 --> 00:03:36,400
for video, for fifty frames
 a second, set it to one 100.

56
00:03:36,400 --> 00:03:38,720
Having a correct shutter
 speed is very important

57
00:03:38,720 --> 00:03:40,920
if you want to shoot cinematic video. 

58
00:03:40,920 --> 00:03:43,640
The use of ND Filters
 will be needed on sunny days

59
00:03:43,640 --> 00:03:47,920
to block out the light from the sun
 and achieve the correct exposure.

60
00:03:47,920 --> 00:03:52,520
ISO refers to the sensitivity
 as a digital sensor.

61
00:03:52,520 --> 00:03:56,520
The higher the ISO number,
 the more sensitive it is to light

62
00:03:56,520 --> 00:03:59,400
allowing shooting and low
 light conditions.

63
00:03:59,400 --> 00:04:03,360
The downside of increasing your ISO
 is that the higher the number,

64
00:04:03,360 --> 00:04:07,000
the grainier your final image will be.

65
00:04:07,000 --> 00:04:09,360
If you don't feel
 confident to manually control

66
00:04:09,360 --> 00:04:14,160
the exposure of the image at this stage,
 the auto settings do a great job.

67
00:04:14,160 --> 00:04:17,000
Many pilots will set the drone
 to automatically analyze

68
00:04:17,000 --> 00:04:20,720
the light available
 and adjust the settings accordingly.

69
00:04:20,720 --> 00:04:25,000
We can fine tune this by using
 the exposure compensation setting,

70
00:04:25,000 --> 00:04:29,880
which will increase or decrease
 how light our image is.

71
00:04:29,880 --> 00:04:31,880
Although manual settings are encouraged 

72
00:04:31,880 --> 00:04:35,160
to have total control
 over the image and final output,

73
00:04:35,160 --> 00:04:37,520
auto settings can be useful
 in changing weather

74
00:04:37,520 --> 00:04:43,760
conditions and brightnesses to ensure
 you capture a usable shots every time.

75
00:04:43,760 --> 00:04:47,080
Moving on to color
 profiles and RAW photos,

76
00:04:47,080 --> 00:04:51,040
some editors prefer a flat image
 or a video file to edit with.

77
00:04:51,040 --> 00:04:55,440
This gives them more freedom
 to colour correct and grade the image.

78
00:04:55,440 --> 00:04:56,960
You will see some drones offer 

79
00:04:56,960 --> 00:05:00,840
normal mode, which is a straight
 out of box contrasty lock,

80
00:05:00,840 --> 00:05:03,680
which can be delivered
 straight to your client.

81
00:05:03,680 --> 00:05:06,800
You will also find D-Log
 and D-Cinelike (or HLG)

82
00:05:06,800 --> 00:05:09,520
which give more flexibility
 in post-production.

83
00:05:09,520 --> 00:05:12,640
These latter profiles
 have a slightly different gamma curve

84
00:05:12,640 --> 00:05:17,440
and lack any contrast or saturation
 straight out of the camera.

85
00:05:17,440 --> 00:05:21,840
Using a less contrasty
 profile gives us more dynamic range.

86
00:05:21,840 --> 00:05:24,760
This gives us more flexibility and data

87
00:05:24,760 --> 00:05:28,640
in both the highlights
 on the shadows in post-production.

88
00:05:28,640 --> 00:05:30,920
If you're comfortable with color
 grading your footage,

89
00:05:30,920 --> 00:05:33,920
it's always best
 to use one of these profiles.

90
00:05:33,920 --> 00:05:36,600
Moving on to raw photos, 

91
00:05:36,600 --> 00:05:41,960
raw photos preserve more data in the image
 file, meaning just like D-Log vs normal.

92
00:05:41,960 --> 00:05:43,720
You have more to work with in the edit 

93
00:05:43,720 --> 00:05:47,520
than just shooting
 a compressed file type like JPEG.

94
00:05:47,520 --> 00:05:50,400
Raw Files, however,
 are much larger than JPEG.

95
00:05:50,400 --> 00:05:55,840
So be sure you have enough space on your
 micro SD card before taking to the air.

96
00:05:55,840 --> 00:06:00,360
Codecs and bitrate:
 A Codec is basically the file type, which

97
00:06:00,360 --> 00:06:05,520
your camera will encode or decode in order
 to play the file back on your computer.

98
00:06:05,520 --> 00:06:10,120
The bits rate refers to the depth
 of information stored in the video file.

99
00:06:10,120 --> 00:06:12,640
This is essentially the compression
 of the video file

100
00:06:12,640 --> 00:06:16,720
and plays a part in how easy it is
 to edit on your computer as well.

101
00:06:16,720 --> 00:06:19,880
The higher the bit rates, the higher
 the quality video,

102
00:06:19,880 --> 00:06:23,640
but also means the file
 size will be much larger and your computer

103
00:06:23,640 --> 00:06:26,880
may find it harder to edit. 

104
00:06:26,880 --> 00:06:32,480
Focus: on the DJI Mavic pro drones
 it's very easy to set your focus.

105
00:06:32,480 --> 00:06:36,320
Assign the focus control to C1 or C2
 so the focus can

106
00:06:36,320 --> 00:06:40,480
easily be reset to the current location
 of the focus rectangle

107
00:06:40,480 --> 00:06:43,280
half press the shutter button
 to focus the camera

108
00:06:43,280 --> 00:06:47,480
or simply tap on the screen
 to tell the camera what to focus.

109
00:06:47,480 --> 00:06:50,440
If you enable autofocus continuous mode,

110
00:06:50,440 --> 00:06:55,760
it'll autofocus when the object
 or the drone stops momentarily.

111
00:06:55,760 --> 00:06:58,440
Now you know all
 you need to go out and shoot

112
00:06:58,440 --> 00:07:01,640
high quality aerial video and photography.
