====Performance====
Even though using high resolutions (or ''Source'') increases quality of output video as the output becomes more similar to the source, it might cause [[Output#Frame_rate|fps]] drops. Size of the output also become larger in higher resolutions. You can choose lower resolutions to increase frame rate, reduce size of the output file and prevent performance issues.
====Scaling====
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.
====Limit====
Screenbits supports resolutions up to ''3840 × 3840'' (also referred as ''4K'') unless you are running x86 version of the app. However since recording in very high resolutions might cause performance issues which affect quality of the output video, Screenbits by default limits the output resolution to ''1920 × 1920''. To remove this limit, you need to turn '''Limit resolution to Full HD''' switch off from video settings.
