What is a .PROJECTOR file?
A .PROJECTOR file is a type of document specifically used to store the transcript of a screencast, which is a digital recording of a computer screen output, often accompanied by audio narration. This file format is generated by the Google Screencast application, which is designed for use on ChromeOS devices.
The content inside a .PROJECTOR file is formatted in JSON, which stands for JavaScript Object Notation. JSON is a lightweight data-interchange format that is easy for humans to read and write, and easy for machines to parse and generate. In the context of a .PROJECTOR file, the JSON structure is used to record the exact words spoken by the user during the screencast. This transcript is crucial for accessibility purposes, such as providing text for those who are deaf or hard of hearing, and for creating searchable text that accompanies the video content.
When you play back a screencast recording on the Google Screencast app, the .PROJECTOR file works in tandem with a .WEBM video file. The .WEBM file contains the video recording of the screencast, while the .PROJECTOR file provides the textual transcript. During playback, the transcript is displayed in the Transcript pane of the Google Screencast app, allowing viewers to read along with what is being said in the video.
To open a .PROJECTOR file, you can use any standard text editor because the file is essentially a text file with JSON data. Text editors are available on all platforms, including Windows, macOS, and Linux. Examples of text editors include Notepad on Windows, TextEdit on macOS in plain text mode, and Gedit on Linux. Additionally, since the .PROJECTOR file is associated with ChromeOS and the Google Screencast app, you can also manage and view these files directly within this operating system and application. Google Chrome, which is included with ChromeOS, can also be used to view and edit .PROJECTOR files.
In summary, a .PROJECTOR file is a valuable component of a screencast recording on ChromeOS, providing a textual transcript of the audio content. It can be opened and edited with any text editor across different operating systems, or managed directly within the Google Screencast app on ChromeOS.
