I'm using a logitech c903e webcam and a blue yeti usb microphone on my HP Pavilion 15 laptop to record tutorials for my upcoming ecourse and the audio skips right around 1:30-1:40. It continuously slows until the end of the video. I am behind on course creation and need to get some videos made asap. Any help would be greatly appreciated! 

Here is a video of what it looks and sounds like when I record.

I am not familiar with your hardware, but I do all my screencasting, with/without built-in webcam, and using external USB mic on my laptop, without issues

the behavior you describe suggest that your system is stressed trying to capture both screen and webcam?

do you have issues if you do not record webcam?

John, I keep task manager open [minimized] all the time when working with Camtasia;

when doing system-stressful stuff with the CS editor, I watch CPU usage, CS process memory use, and total system memory use [process tab and performance tab]; I can usually spot approaching issues in time to stop, save, exit, relaunch, and reload; this has saved me from losing work on many occasions, and allows me to avoid degraded editor and production performance, as well as preventing hangs and crashes

there may be better software tools for tracking system resources being used, but I'm not familiar with them

Could notes on this older post offer you any clues?

(Sorry long thread) The 1 step or 2 step method noted should help you.

Do you have webcam audio turned off, and only the Yeti mic on? I assume yes
The Logitech camera you have is a good one.
It records webcam video direct as an h.264 MP4 video file.

Best step for now, may be to record your screen, then record your webcam as a 2 step process. Record your screen first then, webcam second. Add the Logitech recorded & saved MP4 video file onto the time line, edit & produce your project.

What may be happening during recording is that while CS8 is recording your screen, CS8 is re-encoding, re-recording the MP4 video output from your camera, and your PC is running out of system resources. Windows easily can use 3 gigabytes of RAM. If installed RAM is 4, or better 6gig., this may help a bit, but a solution today is perhaps best by using the two step method.

In a future product update, it would be nice to be able to configure Camtasia to accept & auto-store a Logitech MP4 recording video direct onto a user defined timeline track, without doing anything to the video during capture/recording process. At present this is not possible, and might never be possible.

As a side note, you can make 2 recordings of your voice at the same time while recording the screen. 1. in Camtasia, 2nd in Audacity software. Now you could have two voice recordings to compare. See this TechSmith blog post for more about Audacity.

Pls post any test results or solution you might find.
Hope this may start to help.

PS. This blog post may also offer you some tips.

Hi Krissy~ I'm having similar issues as well, but mine skips and jumps which is frustrating. I have a music page on FB and YouTube and want to record some songs live on video, but cannot because of this issue. I love the quality of my webcam so I want to continue using it. Tried plugging the mic into a laptop and the video still lagged a bit and was hard to line up together. Here is a sample of my issue. (also, I found this link when researching the problem just now, so I don't know if it will help any....?? Haven't tried it yet...)

Please let me know if you find any solutions! :)

In my life on a Fender Ukulele. First off. You sound great, nice job.

This may or may not help. Camtasia has issues when working with some audio formats. I don't know what type of mic you use but I suspect it must be a nice one.
If you can change you mic settings to 44,100 Hz at 16 bits. Camtasia handles that setting very well. 48,000 seems to be a real sticking point for Camtasia.

44,100 is DVD Quality and still produces highs nobody can even hear. So I think 48,000 only really helps for studio editing. But you probably know more about it than me. 

Good Luck, Joe

Thank you for the nice compliment on In My Life Joe~ Always appreciated!

The mic isn't great actually, just a $100 M-Audio. I record all of my songs on it in my walk-in closet (shhhh...don't tell anyone).

Thank you for the suggestions. I will give them a try! :)

Hi Joe~ Just wanted to give an update on my webcam audio-skipping/jumping issues.

Because the videos that I want to record are solely for my music page, I really want the audio to be superior and the webcam mic isn't adequate for vocal recording.
So I did some fiddling around this morning and just figured out a solution. I disabled the webcam mic and plugged my regular recording mic into a laptop and recorded the vocal onto the recording program on there. Then I synced the audio and video in my computer video editing program and aligned them. Worked great. Obviously more work to do it that way than just using a webcam mic to record it, but since these will be for the music page the quality of the sound and my voice is the most important component. Then I can edit and mix the audio track in Pro Tools before aligning it with the video so the sound will be at it's best. Happy I figured it out!

Thank you again for your quick response and help!

Ha! Yes!  Working on the next song right now actually. It's for a dear friend who is terminally ill. Hence the wanting to record the song in a more personal form; singing it live on video.

I'll attach the link to it here once it's done so that you can see the difference sans the hop-skip-and jumping audio :)
