VideoScreenCapture
creates a temporary interactive interface for capturing from the main screen into a video.
VideoScreenCapture[source]
captures from a screen or part of a screen specified by source.
VideoScreenCapture[Dynamic[var]]
creates a non-blocking asynchronous interface to capture video and saves the result in var.
VideoScreenCapture[Dynamic[var],source]
captures asynchronously from the specified source.
Details and Options
- VideoScreenCapture can be used to record videos from screens as well as parts of the screens such as notebooks.
- Once stopped, VideoScreenCapture[] returns a Video object that includes the captured video.
- Once stopped, VideoScreenCapture[Dynamic[var]] assigns the captured video to the variable var.
- VideoScreenCapture by default captures the whole first screen.
- Possible settings for source to capture other screens or parts of a screen are:
-
n recording from the n 
connected screen{{xmin,ymin},{xmax,ymax}} recording from the region bbox of all the first screen {n,{{xmin,ymin},{xmax,ymax}}} recording from the region bbox of the n 
screenNotebookObject[…] recording from a notebook displayed on screen - VideoScreenCapture takes the following options:
-
AudioInputDevice None audio input device to use for capture CaptureRunning False whether to immediately start the capture MaxDuration ∞ maximum duration for capture - By default, VideoScreenCapture places the new video under the "Video" directory in $WolframDocumentsDirectory.
- Options to control properties of the output video are:
-
BitRate Automatic approximate bit rate to use CompressionLevel Automatic compression level to use FrameRate Automatic the frame rate to use GeneratedAssetFormat Automatic the format of the result GeneratedAssetLocation $GeneratedAssetLocation the location of the result OverwriteTarget False whether to overwrite an existing file RasterSize Automatic raster size of the output video VideoEncoding Automatic video encoding to use
