Audio cutting shorter than video when screen capturing .
at first it seems the screen capture is short but after separating audio and video the video can be extended but the audo is the one that is actually short/missing. 

I tried importing the temp file but its the same issue. the screen capture feature doesnt record all the way through. i didnt do pauses or start overs. 

im on mac sierra 10.12 and capturing the system audio.

 below is the image showing the audio shorter. sometimes is more , sometimes is less.

That has happened to me with an external audio interface attached.
I'm suspecting you have one given what's in your screenshot...

If memory serves, it might have something to do with using both your USB device and system audio capture.   In this case if your Kontakt has to be connected that could be an issue. 

Some audio folks also own a tool called Audio Hijack, by Rogue Amoeba (Piezo from the same company might also work at a lower price point)

You could try disabling Camtasia system audio capture, and use one of those product to capture the audio, then drop that audio into your timeline.  Naturally try the demo of those product and only buy them if it makes sense and fits in your workflow. I bought a tool from them called "loopback" and that might be another option, but it's pretty technical/specific.

And finally, you might try demos of other similar tools to Camtasia, they each have their own method of audio capture and one might not suffer from the same bug (though i think I tried this with another tool once and found it had the EXACT same problem at the time.)

Just a quick update, with some bad news as it relates to Camtasia,  I just tried this with version 3.1.5 (the latest as of this writing) on MacOS 12.13.4 (the latest as of this writing) and the problem still persists. I also tried the latest version of a similar product and that worked fine.

While it's unfortunate that this specific issue exists, Camtasia is still a great product and does many many many things right, so please don't take this to mean that the other product is 'better'. Both products have their plusses and minuses, and this just happens to be a case where the other product might be a better fit.

its great. love it. my workaround is to record the audio inside a daw or via the headphone output on another device and then import it. not ideal but editing is much easier and nicer than premiere or fcp.

Audacity is great for recording audio. I record 3-4 takes of each scene there, assemble the best voiceover track from all the takes, then import that one track to Camtasia. Then the real editing begins...

Yes. Many programs are great for audio recordings. And plenty of workarounds. The best and easiest would be for tech smith to resolve the issue.. but thanks.
