Combined video/audio tracks vs. separate video/audio tracks

When I record in PowerPoint, the audio and video tracks are combined.  When I record from the screen, the audio and video tracks are separate.

1.  Why are they combined when I record in PowerPoint?

2.  When I record from the screen, how can I get both tracks to be combined on the timeline?

Normally when you record from the screen you have an option to also record "System Sound".

My guess here is that the separate audio track is that "System Sound" and the video track actually has the microphone track combined with it just as you see when you record from PowerPoint.

You can combine audio and video, audio and stills, video and graphical effects, or heck, select every thing in the timeliness and combine it as a stream of audio visual delight by going this: select (by pressing and holding down the CTRL key on your keyboard) and click the items you want to combine. You can now release the ctrl button. Right mouse click on one of the selected items. Choose "Group". That's it!

Tip: edit your sound track/video first BEFORE you add you special effects (especially Pan/Zoom), select all and group everything. Add your effects now and they will act just the way you would like them to, even between hard Cuts in edits.

Rick,

Your comment was helpful, especially since I just started this.  Two questions:

1.  How do you define system sound?  What are some examples?

2.  How could you eliminate the sound of typing on the keyboard as well as mouse clicks?

Imagine you were to play a streaming video. You would use the System Sound to capture the audio track of the video.

As for the sound of typing, we need to clarify a bit. If you were using a laptop, it's possible that the laptop microphone could have recorded the sound of typing. And that typically sounds like a herd of elephants clomping through. If that's the sound you are referring to, you would need to separate the audio and video, then perhaps delete the audio. Then you could re-record it.

As for the click sounds, they appear to be recorded in that system audio track. So deleting that track should take care of that.

Cheers... Rick :)

JulianF1970,

Interesting comment.  I didn't know you  could group everything together.  What is the benefit of grouping tracks together?  Why might somebody do this?

Look at your library and try adding a Motion Graphic Lower Third. These are usually grouped elements.

Michael,  Another reason is for convenience for moving.  If a section of "video" were to be moved then you have, at least, two options.  Select all elements (callouts, video, audio, etc.) to be moved on the various tracks and move.  Reselecting for minor adjustments.  Or, select all elements, group, move.  (Cuts might need to be made first before moving.)

I just installed Camtasia  9 and I do not see an option to separate the audio and video. Does this version have that capability?

Hi Pam,
If your recording is a TREC created using Camtasia Recorder, and you recorded audio, then you can right-click on the recording on your timeline and choose Separate Video and Audio from the menu.

Just for others who might come to this post, I am including links to two help topics here.
