I am using Comtasia 8.1 version for video recording ( ppts and camera) on my laptop. It seems difficult to have both. In addition, the sound is not good at all.

Am I making some technical errors?

Often, the machine is not powerful enough to encode the camera video + screen video, plus 2 audio streams (microphone, system audio).  Depending on the recording dimensions, particularly the camera dimensions, it is possible to over-tax the CPU.  When this happens, the audio can sound poor or drop out completely.  Unfortunately, there are limits to how many full dimension video streams can be encoded in real time, even by higher end PCs.

This happened far too often with version 8.  In version 9.x, we made some performance improvements and placed some constraints on the camera dimensions to try to prevent this from happening.

The solution is to lower the load on the CPU during recording.

One option is to use a phone or hardware camera to record the camera video separately as an MP4.  Then download the video to your computer and import it into your project.  Most phones can record to MP4, and the quality is usually quite good.  Camtasia does not support all camera formats, so please make sure you check format compatibility before you spend a bunch on a hardware camera.  This approach does require a little extra file management, but it should lessen the CPU load during recording, which should help with the audio quality problem you describe.

Another option is to lower the dimensions of the camera video as much as possible.  This is less ideal, because if you record at smaller dimensions, the video may look blurry if you try to size it to fill the full frame later.  It's always best to start with the highest quality recording possible.  But if you only need a small camera video in the corner, you might be able to reduce the camera dimensions enough to make this option work.

Sorry for the trouble.  I hope this information helps you get the most out of Camtasia v8.
