1
00:00:00,005 --> 00:00:02,000
- [Instructor] It's pretty common in my workflow

2
00:00:02,000 --> 00:00:05,002
to separate the audio track from the video track,

3
00:00:05,002 --> 00:00:07,003
and work with it independently.

4
00:00:07,003 --> 00:00:10,000
Maybe I don't need the video track, just the audio.

5
00:00:10,000 --> 00:00:11,008
Perhaps the audio is perfect,

6
00:00:11,008 --> 00:00:13,007
but the video isn't quite right,

7
00:00:13,007 --> 00:00:17,003
and I'd like to realign the audio with another video clip.

8
00:00:17,003 --> 00:00:21,000
Or, sometimes the audio is out of sync with the video,

9
00:00:21,000 --> 00:00:23,003
and I need to realign things.

10
00:00:23,003 --> 00:00:24,007
All of these can be remedied

11
00:00:24,007 --> 00:00:28,008
by working with the audio and video tracks separately.

12
00:00:28,008 --> 00:00:30,000
So the first thing I'm going to do

13
00:00:30,000 --> 00:00:31,008
is show you how to separate those.

14
00:00:31,008 --> 00:00:35,000
I'm going to select my clip, right click,

15
00:00:35,000 --> 00:00:39,004
and just choose Separate Audio and Video.

16
00:00:39,004 --> 00:00:41,009
Now I have two separate tracks,

17
00:00:41,009 --> 00:00:44,008
one for audio, one for video.

18
00:00:44,008 --> 00:00:46,009
I could work with each one independently,

19
00:00:46,009 --> 00:00:48,006
or maybe I just need the audio,

20
00:00:48,006 --> 00:00:51,004
and I can delete the video to keep things simple,

21
00:00:51,004 --> 00:00:54,003
and take a bit of a load off my computer.

22
00:00:54,003 --> 00:00:55,004
Now, keep in mind,

23
00:00:55,004 --> 00:00:58,006
I'm working with a copy of my original clip.

24
00:00:58,006 --> 00:01:00,003
So if things get out of hand,

25
00:01:00,003 --> 00:01:01,007
I can always start over.

26
00:01:01,007 --> 00:01:02,008
I'll just delete my clip,

27
00:01:02,008 --> 00:01:05,005
and drag a new instance here to the timeline.

28
00:01:05,005 --> 00:01:10,006
I can't damage my original clip in the timeline.

29
00:01:10,006 --> 00:01:14,003
Now, another common reason for separating audio and video

30
00:01:14,003 --> 00:01:16,008
is to resynchronize the tracks.

31
00:01:16,008 --> 00:01:17,009
I'm going to resync this,

32
00:01:17,009 --> 00:01:21,009
and bring in a new video clip to demonstrate here.

33
00:01:21,009 --> 00:01:25,002
I frequently get help requests from coworkers

34
00:01:25,002 --> 00:01:30,006
for out of sync videos like this one.

35
00:01:30,006 --> 00:01:31,004
All right!

36
00:01:31,004 --> 00:01:34,000
So you have a few Camtasia projects under your belt,

37
00:01:34,000 --> 00:01:35,007
and you're looking to bump up.

38
00:01:35,007 --> 00:01:37,002
You've probably seen that before

39
00:01:37,002 --> 00:01:38,007
in YouTube videos and stuff.

40
00:01:38,007 --> 00:01:40,005
It's highly annoying.

41
00:01:40,005 --> 00:01:44,001
Now I intentionally created this clip to be out of sync,

42
00:01:44,001 --> 00:01:47,006
but it does happen for a number of reasons.

43
00:01:47,006 --> 00:01:49,005
The fix for this is very similar

44
00:01:49,005 --> 00:01:51,005
to syncing a separate audio source

45
00:01:51,005 --> 00:01:53,006
which we looked at in another video.

46
00:01:53,006 --> 00:01:57,008
So first, I'm going to separate the clips again, right click,

47
00:01:57,008 --> 00:02:00,006
separate audio and video.

48
00:02:00,006 --> 00:02:02,007
Now, I need to find a sync point

49
00:02:02,007 --> 00:02:05,006
on both the audio and video tracks.

50
00:02:05,006 --> 00:02:08,004
If I'm fortunate enough to have a clapboard snap,

51
00:02:08,004 --> 00:02:10,000
this is really easy.

52
00:02:10,000 --> 00:02:10,009
But, if I don't,

53
00:02:10,009 --> 00:02:11,009
and I usually don't,

54
00:02:11,009 --> 00:02:13,009
I'm not completely out of luck.

55
00:02:13,009 --> 00:02:16,002
I just need to find something identifiable

56
00:02:16,002 --> 00:02:18,003
in the wave form like a clap,

57
00:02:18,003 --> 00:02:20,000
or maybe a loud vocal part,

58
00:02:20,000 --> 00:02:22,008
somebody bumped the microphone, music starting,

59
00:02:22,008 --> 00:02:23,007
something like that

60
00:02:23,007 --> 00:02:26,007
that I can use to line up the two tracks.

61
00:02:26,007 --> 00:02:28,004
In this case, I have none of that,

62
00:02:28,004 --> 00:02:29,003
but it's okay.

63
00:02:29,003 --> 00:02:32,004
I'm going to just line up the beginning of the wave form

64
00:02:32,004 --> 00:02:33,006
with my mouth opening,

65
00:02:33,006 --> 00:02:34,005
which I just realized

66
00:02:34,005 --> 00:02:37,001
I stopped on a really lovely frame there.

67
00:02:37,001 --> 00:02:39,006
So what I'm going to do here is scrub through,

68
00:02:39,006 --> 00:02:41,005
and just as my mouth opens,

69
00:02:41,005 --> 00:02:43,000
the audio is clear down here,

70
00:02:43,000 --> 00:02:44,006
it's way out of sync,

71
00:02:44,006 --> 00:02:46,009
I'm going to just trim this up a bit,

72
00:02:46,009 --> 00:02:49,003
and pull it down,

73
00:02:49,003 --> 00:02:53,001
just a little bit more.

74
00:02:53,001 --> 00:02:55,005
All right, and let's see how that worked out.

75
00:02:55,005 --> 00:02:56,003
All right!

76
00:02:56,003 --> 00:02:58,009
So you have a few Camtasia projects under your belt

77
00:02:58,009 --> 00:02:59,009
and you're look.

78
00:02:59,009 --> 00:03:01,003
And they're in sync again!

79
00:03:01,003 --> 00:03:04,009
You just have to find that magic spot.

80
00:03:04,009 --> 00:03:07,002
Now, let's clean this up a little bit.

81
00:03:07,002 --> 00:03:09,006
I'm going to pull this out to align it with that clip,

82
00:03:09,006 --> 00:03:12,007
and then I'm going to trim this clip here so they match up,

83
00:03:12,007 --> 00:03:16,006
select both, and so that they don't get out of sync again,

84
00:03:16,006 --> 00:03:20,000
I'm going to right click and Group.

85
00:03:20,000 --> 00:03:21,004
And now I can move them together

86
00:03:21,004 --> 00:03:24,009
without the audio and video getting out of sync.

87
00:03:24,009 --> 00:03:27,004
The takeaway here is that Camtasia clips

88
00:03:27,004 --> 00:03:30,006
are composed of multiple tracks.

89
00:03:30,006 --> 00:03:33,001
You can work with audio and video separately

90
00:03:33,001 --> 00:03:36,006
by separating the tracks, and editing as needed.
