Software that display high-motion graphics take up a lot of CPU resources and may result in blocky screen recordings. A high-end computer is required to handle both the graphics and recordings together. You can smoothen the recording significantly by: Increasing the frame rate to 75 or higher (as high as possible) so every frame in the graphic is correctly recorded. Decreasing the area of the screen to be recorded. If the software displays graphics in a window then use Region recording to record only that portion of the software.
