I am using Avid Pro Tools 10 on Mac OSX Lion, and want to create some demo videos.

I have set up Pro Tools to utilize both a single audio device for playback, and an aggregate device for playback.

However, when I try to capture system audio, I am seeing the audio gets captured, but it is double speed, and double pitch. Plus, only the top half of the waveform is shown in the timeline.

I had also tried recording a demo with Jing, thinking I could then import the resulting SWF file into Camtasia, but Camtasia will not accept it.

I also tried using Quicktime, and got the audio recorded -- but only the left channel!

Any ideas?

I have an update: I was able to successfully record audio with video using a demo of a program called ViewFow (I think is what it's called -- $39 from the Mac store) and also Soundflower/SoundflowerBed.

It is sad that no one has responded on this issue. I have been a long time user of Camtasia on Windows, but am now looking at setting up a system for my own ventures, and Camtasia for Mac falls flat on its face right out of the shoot.

The fact that Jing properly records the audio, even without Soundflower, and another program works along with Soundflower, convinces me that the blame cannot be laid on OSX.

Anyone from Techsmith care about making another sale? Get this fixed or I will have to find something else.

Another update: I found another program called Voila that properly records audio when capturing screen video -- not system audio -- but at least I can capture whatever I route through Soundflower using Soundflowerbed. Even at 48khz, the capture is perfect.

This is very sad, really. Is there a possibility that someone from Techsmith at least acknowledge the existance of this problem, and that they will perhaps consider maybe thinking about possibly looking into a potential solution?

Side note -- I had not noticed before that the way the clips are displayed on the timelime, only showing the top half of the waveform is actually intentional. So the various sound problems I have been seeing have nothing to with that.

Hi,

So sorry we didn't reply to your post. I know it's frustrating to be talking into a black hole.

We are aware that some customers are experiencing issues with the new system recorder. Those problems have been fixed for the next release, but until that goes live you can get a special build from our technical support.

UPDATE:

I'm glad to report that after I submitted a ticket to Customer Support at the link Conan provided, I was given access to impending build of Camtasia:Mac 2.2.2.

I got it installed, got the system audio add-on installed, and the system audio now records properly.

FWIW: When I installed the system audio add-on, it never "appeared" as available for use in the screen capture interface. I tried installing it several time, but always had the same results. Only after I rebooted OSX (which does not seem normally required) was I able to see the system audio option appear in the screen capture interface as I expected.

A big Thank you goes to Techsmith Customer Support!

I consider this topic "answered".

I'm closing this thread since Camtasia Mac 2.3 is now released and 2.2.2 solved the problem.
