- [Instructor] It's pretty common in my workflow
to separate the audio track from the video track,
and work with it independently.
Maybe I don't need the video track, just the audio.
Perhaps the audio is perfect,
but the video isn't quite right,
and I'd like to realign the audio with another video clip.
Or, sometimes the audio is out of sync with the video,
and I need to realign things.
All of these can be remedied
by working with the audio and video tracks separately.
So the first thing I'm going to do
is show you how to separate those.
I'm going to select my clip, right click,
and just choose Separate Audio and Video.
Now I have two separate tracks,
one for audio, one for video.
I could work with each one independently,
or maybe I just need the audio,
and I can delete the video to keep things simple,
and take a bit of a load off my computer.
Now, keep in mind,
I'm working with a copy of my original clip.
So if things get out of hand,
I can always start over.
I'll just delete my clip,
and drag a new instance here to the timeline.
I can't damage my original clip in the timeline.
Now, another common reason for separating audio and video
is to resynchronize the tracks.
I'm going to resync this,
and bring in a new video clip to demonstrate here.
I frequently get help requests from coworkers
for out of sync videos like this one.
All right!
So you have a few Camtasia projects under your belt,
and you're looking to bump up.
You've probably seen that before
in YouTube videos and stuff.
It's highly annoying.
Now I intentionally created this clip to be out of sync,
but it does happen for a number of reasons.
The fix for this is very similar
to syncing a separate audio source
which we looked at in another video.
So first, I'm going to separate the clips again, right click,
separate audio and video.
Now, I need to find a sync point
on both the audio and video tracks.
If I'm fortunate enough to have a clapboard snap,
this is really easy.
But, if I don't,
and I usually don't,
I'm not completely out of luck.
I just need to find something identifiable
in the wave form like a clap,
or maybe a loud vocal part,
somebody bumped the microphone, music starting,
something like that
that I can use to line up the two tracks.
In this case, I have none of that,
but it's okay.
I'm going to just line up the beginning of the wave form
with my mouth opening,
which I just realized
I stopped on a really lovely frame there.
So what I'm going to do here is scrub through,
and just as my mouth opens,
the audio is clear down here,
it's way out of sync,
I'm going to just trim this up a bit,
and pull it down,
just a little bit more.
All right, and let's see how that worked out.
All right!
So you have a few Camtasia projects under your belt
and you're look.
And they're in sync again!
You just have to find that magic spot.
Now, let's clean this up a little bit.
I'm going to pull this out to align it with that clip,
and then I'm going to trim this clip here so they match up,
select both, and so that they don't get out of sync again,
I'm going to right click and Group.
And now I can move them together
without the audio and video getting out of sync.
The takeaway here is that Camtasia clips
are composed of multiple tracks.
You can work with audio and video separately
by separating the tracks, and editing as needed.
