Abstract: Techniques for capturing videos of content displayed and/or generated by a web-based application are described herein. The videos may be captured by automating screenshots of the content within a headless browser at a fixed frame interval. The headless browser may be used to automate control of the web-based application to generate the content and capture screenshots of the content as the content would appear if the web-based application was being accessed through a traditional web browser graphical user interface. The screenshots may be captured at specific frame intervals while the content is being generated. Additionally, the headless browser or a server executing headless browser may wait for the web-based application to load individual frames of the content before capturing screenshots. The captured screenshots may then be combined to generate a video of the content.
