How to edit audio AFTER recording video/audio from PowerPoint?

  • Updated 5 years ago
I am using Camtasia 7.1.1. 

Here is what I want to be able to do:

1) Record video and audio from PowerPoint

2) Extract the audio portion from Camtasia...and take it over to Audacity for audio processing / clean-up / editing (but NOT change its length)

3) Replace the original audio with the processed audio...while keeping all the screen transitions in place as they are.

Is there any way to do this?

easy

with project on timeline, export audio [on file menu, ctl-D], that will give you a WAV file; open the WAV in Audacity and edit; export the edited WAV from Audacity; import that new file into the project and put the new audio clip on timeline; silence the original audio

Yeah, it sounds like you already have it planned out.

Here's what I do a little differently than previously suggested...

1. Export video from PowerPoint to .mp4 format.
2. Open video imported into Camtasia and drag into timeline.
3. Separate Audio and Video from that file in timeline.
4. Export audio as stated above and then open in Audacity.
5. Make edits in Audacity as required then export from Audacity,
6. Import new audio into Camtasia.
7. Line it up with the old audio on the timeline.
8. Delete old audio.

I'm extra weird about how I do things like this, but I've had nothing but perfect results thus far.

Thanks,

Kyle

I do PowerPoint videos ALL the time. Here's a 3 video tutorial series I call, "The Ultimate Guide To PowerPoint Video Recording". It uses Audacity for audio narration:

Video 2: The Better Method:



Video 3: The BEST Method:

I just noticed the question was for CS version 7. The "Best Method" tactic I use won't really work as shown in my tutorial but the first two videos can be applicable...

I'd highly recommend upgrading to CS 8 if you do videos seriously? ;-)

Kyle, where would I learn more about "7. Line it up with the old audio on the timeline"?

Well, it depends on what you're doing to your audio in Audacity. If the audio is the same exact length when you bring it back into the timeline, you can just line it up on another layer with the beginning of the older audio then delete that old audio.

I pull my audio into Audacity because the noise reduction is better in there in my opinion. Camtasia had noise reduction, but...
