Hardware acceleration. On Windows 2000 or Windows XP, disabling hardware acceleration can dramatically increase capture frame rates (or reduce CPU usage at a given capture frame rate). To disable hardware acceleration on Windows 2000/XP, open the Control Panel "Display" applet. On the Settings tab, click the Advanced button. Then set the Hardware acceleration setting to None in the Troubleshoot tabbed dialog.
Capture dimensions. As a general rule of thumb, the lower the capture dimensions used, the faster the computer will be able to capture the screen. If the video recorded is choppy, try decreasing the capture dimensions, and either resizing the application that is being recorded to fit into this new dimension, or enable the Zoom & Pan option in Camtasia Recorder. The smaller the size of the capture area, the better.
Codec choice. (The following codec tips only apply to Camtasia Studio ). Always use the TSCC video codec during capture for low complexity, low motion content. With very high complexity, high motion, real-world content, capture performance may be improved by using a lossy video codec (e.g., Microsoft Video 1 or Microsoft MPEG-4 v2). You may also manually bump up the capture frame rate to try and improve the capture frame rate.
Desktop color depth. The lower the better. Of course, some applications require at least 16-bit color. Note that some graphics cards perform better at 32-bit color than at 16-bit color. You may need to experiment with capturing at 16 vs. 24 vs. 32-bit color on any particular system..
CPU speed. The faster the better. This is pretty much the dominant factor in capture performance when all of the other parameters are fixed.
Graphics card. Some graphics cards and/or drivers have better 2D performance than others.
Hard disk speed. Always use the fastest local hard drive available when specifying the temporary file folder.
