Hey Bob

How do you connect the speaker jack to the audio input jack?

thanks

I believe that in the trial version, you can only record audio using the microphone, and not through the internal input. When I record live streaming video, I don't want to record through the microphone. Instead, I connect the speaker / headphone jack to the audio input jack and I am able to record the exact audio signal that is being broadcast, with no loss of signal or background noise that would come from using the microphone.

I'd like the solution too - perhaps someone can post it on here - I'm on a mac so a solution for that would be good - don't want to just record the speaker audio

I don't have an answer and have found this problem too when recording a live video stream of a sporting event - I thought it was just the bad connection from Italy to Australia.

I guess if others are experiencing that it might have something to do with the frame rate the software is recoding at. When shooting video you get jerky movements when you start shooting above 1/50th shutter speed.

I've just done a google search and found this helpful info on a competitor's website http://www.techsmith.com/tutorial-camtasia-recording-performance-prior.html

Basic Tips to Improve Recording Performance

 

Your frame rate is the number of frames captured per second. For the smoothest recordings you want to strive to achieve the highest frame rate. By default the Camtasia Recorder tries to capture 15 frames per second. The recorder will drop frames if the computer becomes overburdened and the recorder cannot keep up. Here’s some ways you can improve performance:

• Record a smaller portion of your screen. Recording the full screen is harder than recording a single window.
  
• Close any applications you don’t need. They’ll hog memory, and since screen recording is a CPU-intensive process, you want to free up everything you can.
  
• On Windows Vista, disable the Aero color scheme. To do so: Start > Control Panel > Appearance and Personalization > Personalization > Change the color scheme. Choose Windows Vista Basic, Windows Standard, or Windows Classic. On Windows XP, you can disable Hardware Acceleration. To disable hardware acceleration globally, right-click on the desktop and select Properties > Settings > Advanced > Troubleshooting. Set the acceleration slider to None. This method will turn off acceleration for all applications until it is manually turned back on.
  Another way to globally disable acceleration is to configure the Camtasia Recorder to turn off acceleration before each recording session and turn it back on when the recording is stopped. Tools > Options > Capture > Disable Display Acceleration During Capture. This has the side effect of blanking the screen each time the recording is started and stopped.
  There are some applications which require hardware acceleration to run properly. Games, CAD programs and TV cards are some examples.
  
• Looking for an excuse to get a new computer? If so, the statistic you want pay the most attention to is CPU. RAM and graphics cards are important, but when you’re specifically talking about recording power, Camtasia Studio is mostly taxing your CPU. Another compromise idea is to borrow a fast computer to get your recording done, then edit on your slow computer.
  

Understanding Challenges when Recording High-Motion Content

 

There are essentially two approaches to capturing screen content. Camtasia Studio uses a lossless approach. Alternatively, some recording software uses a lossy approach. Why do you care about lossless and lossy? Fair question.

Let’s cover lossless first. In this method, the recorder attempts to capture every pixel on the screen perfectly. If the recorder is stressed and can’t do it, the frame is just dropped. One way to think of it is you’ll get a series of crystal clear images, but the dropped frames make the recording jerky. Lossy recording takes a different approach. It attempts to capture every frame, but when it gets stressed it doesn’t necessarily drop the frame—instead it’ll sacrifice quality. So you may end up with a smoother recording, but you’ll see some artifacts and maybe it’ll seem blurrier.

What’s the takeaway?

Lossless recording (Camtasia Studio default) is ideal for capturing typical screen content—websites, various software applications, and PowerPoint presentations. Lossless recording suffers when you try to capture things with a lot of motion—like a streaming video, a video game, and so forth.

it also talks about another codec to record in - DivX - I haven't played around with this

So you need to select an appropriate frame rate for what you are trying to capture and lossless or lossy as per above

hope that helps - I'm no expert though

I'd like an answer to this one too please

perhaps you could share your solution so that others can use it? thanks
