Record captured video and audio into video or audio files using the recorder. Output file format depends on the selected [[Capture_mode|capture mode]] at the start of recording. If current mode is a video mode such as screen recording, an '''mpeg4''' video output file (.mp4) is generated, otherwise, the output is an '''mpeg4 audio''' file (.mp4a). Output files are compatible with almost any multimedia player and editor software.
== Record, stop and play ==
#From the application window, click '''Record''' button to start recording.
#Click '''Stop''' button when you want to stop recording.
#Click '''Play''' button to view the recorded video using default player on your system.
You can also use [[Hotkeys|hotkeys]] or [[Notification_area|notification area]] to start, pause and stop recording or enable [[Auto_stop|auto stop]] feature to stop recording automatically.
== Pause and resume ==
Recording can be paused and resumed later whenever you want.
#From the application window, during recording, click '''Pause''' button.
#Click '''Record''' button whenever you want to continue recording.
== Location ==
=== Output Folder ===
By default, recorded videos files are saved in ''Videos'' folder inside a folder named ''Screenbits''. You can change the view output folder to any location on your storagefiles from [[Files|files]] section.
Output folder can change to any location on your storage. To change the output folder:
#Select '''Settings''' from '''Menu''' to open ''Settings''.
#Click '''RecorderOutput''' from the side bar to open ''RecorderOutput'' settings.#Click '''Browse...''' button under ''Outputfolder'' section to open ''Browse for folder'' dialog. #Select the folder you want to save videos into.
Note: Make sure your user account has write access to the selected folder and also the folder is in a storage device/drive with enough free space. Your security software might also prevent the application to access the output folder.
To use a different name for output files:
#Select '''Settings''' from '''Menu''' to open ''Settings''.
#Click '''RecorderOutput''' from the side bar to open ''RecorderOutput'' settings.#Enter the desired template under ''Enter a File name template for file name''. Optionally you can use one or more placeholders in the file name. === Output Format ===Output file as saved as mpeg4 (.mp4) files to make them compatible with almost any video player and editor software. Video stream is encoded in H.264 and audio stream is encoded in AAC codec.
== Video ==
To open video settings:
#Select '''Settings''' from '''Menu''' to open ''Settings''.
#Click '''VideoRecorder''' from the side bar to open ''Recorder'' settings.#View and change video settings from ''Video'' settingssection.

Resolution is the number of distinct pixels in each dimension on the output video. You can choose how source of recording (the area on the screen which gets recorded) should transform into the output video by choosing the appropriate resolution and scaling options.
The default value for output resolution is ''100% (source)Source'' which means output resolution is equal to dimensions of the source of recording. For example, if you record in [[Capture_mode#Screen|full screen mode]] and screen dimensions is ''1920 × 1080'', output dimension will be ''1920 × 1080'' which means 1920 pixels horizontally and 1080 pixels vertically. (also referred as ''1080p'')
Depending on the purpose of recording, you might want to choose a different resolution than source. To choose a different resolution, select one of the available resolutions under '''Resolution''' in video options or choose '''Custom''' to enter a custom resolution.
===Scaling===
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 is recommended for screen recording 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 this mode and have video/audio synchronizing issues with 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 current recording session.
===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.
==Audio==
To change format of the output audio:
#Select '''Settings''' from '''RecordMenu''' menu to open ''Settings'' dialog. #Click '''AudioRecorder''' from the side bar to open ''AudioRecorder'' settings.#From ''FormatAudio'' section, select the desired bit-rate, sample-rate and number of channels for the output audio.
Note: If multiple audio sources are selected, Screenbits mixes both audio streams into a single audio track.
