you have the correct camtasia codec? What are you using for audio?

usually it's not the codec, but how you've got Camtasia set up to work, and how you have resources allocated. there are many optimizations to use/set up for the best Camtasia experience, and some of them are machine-dependent.

DSE, i found that MOST of them are machine dependant. to disable HW gfx acceleration is one fo them, also, the screen resolution of what youre trying to capture is another, in turn, if your truing to capture 1280x720 powerpoint slides, with GFX acceleratation OFF, it puts more weight on the CPU as not only does it have to draw these res' but also cpature from these res with a decent enough framerate.

I use it all the time, but it takes a while to get the best config for your system

I used the free one, posted here a few days back, and the audio worked fine. Would only record an .avi at 15 fps though. I chose "What you hear" in Camtasia, which isn't even an option from my sound card and it seemed to work.

I would guess your audio settings are different between vegas and camtasia. Can you set them to the same sample rate?

You can change the frame rate -
in the recorder application, go to tools->option
Select the streams tab
remove the auto configure checkbox.
Than you can set the frame/sec.
Also, they recomend to use the Microsoft Mpeg-4 V2 to reduce the CPU load. I am capturing 800x600 at 25fps.
I don't capture audio - i add it in vegas.

Another point. Once you capture and save, you can extract the camrec contents - in the main camtasia window, import the camrec media, use right button to extract - it is faster and doesn't touch the content.
