→Frame rate
Recording in higher frame rates requires more system resources and also produces larger files so choosing 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.
==== Frame rate mode ====
There are two frame rate modes for recording, ''Variable frame rate'' and ''Constant frame rate'' and . In variable mode, a frame is captured and added to the output video only if it is different from the previous frame. If the frame is identical to the previous one, it is skipped. In contrast, when recording in constant frame rate mode, frames are added based on the frame rate only, regardless of the difference between them. To change the frame rate, click the selector under '''Frame rate mode''' and choose one of the available modes.
Using variable frame rate for screen recording is recommended as it improves recording performance and reduces size of the output file without affecting quality of the output video. However, some video editing software might not be compatible with variable frame rate videos since in a constant frame rate (''N'') video, there are exactly ''N'' frames per second while there is usually less frames in a variable frame rate video.
Recording in constant frame rate mode is not always possible depending on the frame rate and system performance. If the system does not perform good enough, Screenbits automatically switches to the variable frame rate mode to be able to continue recording. You can check [[Statistics]] section to see the actual frame rate mode.
