Output Folder

By default, recorded videos are saved in Videos folder inside a folder named Screenbits. You can change the output folder to any location on your storage.

To change the output folder:

  1. Select Settings from Menu to open Settings.
  2. Click Recorder from the side bar to open Recorder settings.
  3. Click Browse... button under Output section to open Browse for folder dialog.
  4. 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.

Output File

You can enter a template for the output file name that is created by Screenbits. File name may include one or more of the following placeholders:

Symbol Meaning Example
$Y Year 2017
$M Month 05
$D Day 10
$H Hour 03
$N Minute 55
$S Second 20

Default file name is $Y-$M-$D_$H$N$S. When a recording process starts, Screenbits will replace the placeholders in the file name with their actual values so using the default file name, output file name for a recording process that started at 14/05/2017 00:48:49 will be 2017-05-14_004849.mp4. If a file with the same name already exist, an underscore followed by a number will be added to the end of the name to make it unique. (e.g. 2017-05-14_004849_0001.mp4)

To use a different name for output files:

  1. Select Settings from Menu to open Settings.
  2. Click Recorder from the side bar to open Recorder settings.
  3. Enter the desired template under Enter a 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.


Screenbits provides multiple options to configure the output which you can either change quickly from output options or open video settings to access to all of the available settings.

To open output options, click Output options button from application window.

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) which means output resolution is equal to dimensions of the source of recording. For example, if you record in 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.


Even though using high resolutions (or Source) increases quality of output video as the output becomes more similar to the source, it might cause 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.


Screenbits supports resolutions up to 3840 × 3840 (also referred as 4K) unless you run 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.


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 from the screen 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. To change the frame rate, click the selector under Frame rate and choose one of the available frame rates or choose Custom to enter a custom 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. To change the frame rate mode, click the selector under Frame rate mode and choose one of the available modes.

Variable and Constant frame rate

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.


Screenbits allows you to configure bit-rate, sample-rate and number of channels for it.

To change format of the output audio:

  1. Select Settings from Record menu to open Settings dialog.
  2. Click Audio from the side bar to open Audio settings.
  3. From Format 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.
