When using a resolution different than source, the aspect ratio of the output resolution might be different from the aspect ratio of the source of recording. By default, scaling mode is set to '''Aspect Ratio''' which means Screenbits maintains original aspect ratio of the recording source and adds black bars to the output if needed. Use the '''Scaling''' selector to change the scaling mode.
===Frame rate===
Frame rate is the number of video frames which get captured and added to the output in each second. (also referred as ''Frames per'' second or ''FPS'') Videos with higher frame rate look smoother and more realistic.
Recording in higher frame rates requires more system resources and also produces larger files so choosing a correct frame rate based on your system performance and the use case is a key factor of using a screen recorder. Screenbits uses 30 as the default value for frame rate which is a good choice for many use cases such as making video tutorials and product demos.
