→Frame rate mode
==== Frame rate mode ====
There are two frame rate modes for recording, ''Variable frame rate'' and ''Constant frame rate''. To change the frame rate mode, click the selector under '''Frame rate mode''' and choose one of the available modes. In variable mode, a frame is captured and added to the output video only if it is different from the previous frame, otherwise, it gets 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. So in a constant frame rate (''N'') video, there are exactly ''N'' frames per second while there are usually less frames in a variable frame rate video.
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 which causes video/audio synchronizing issues.
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 current recording session.
