The problem is not with the microscope but with the computer displaying the video.
A video stream’s demand on a computer’s hardware depends on the resolution and video frame rate, as well as factors like number of colors and intensity levels that are displayed. As each of these quantities increases, more processing power is needed. Any motion recorded by the camera also takes more number crunching by the computer.
Video processing in a computer is done by both the CPU and the hardware on the video or graphics card. Older computers and small computers such as netbooks and tablets have relatively low-power CPUs and either no graphics card or one with modest capabilities. When these devices are used with one of our microscopes at high resolution and/or with rapid image motions in the microscope’s field of view, the computer is using 100 percent of its video processing power and is still not enough to keep up with the camera’s output. Not every video frame is displayed–resulting in gaps that make the video look choppy or the subject appears to jump.
A possible solution is to use the microscope at a lower resolution. To do this, use the settings in the image capture program you are using. For example, if the resolution giving the "jerky" video is 1200x1600, try settings of 1280x1024 or 1024x768, etc. You can also adjust the frame rate and shutter speed to lower numbers to see if this helps.
A PC with a 4-core processor design or better, 2.6 GHz or faster processor and 2 GB free RAM or more is recommended to minimize these problems.
