Jahshaka Scene File

A Jahshaka Scene File with the .JSF extension is a project file used by Jahshaka, an open source real-time editing, compositing, and effects system. It saves a scene that you are building or editing inside Jahshaka, collecting information about your layers, media, effects, animation, and the structure of the scene. When you save your work within Jahshaka using "Save" (or similar), the JSF file records just the scene you are working on - not fully rendered video, nor your media assets themselves. You then use Jahshaka to open that file later to continue editing, to preview, render, or export the final output.

The file is XML-based and begins with an XML declaration indicating version 1.0 and UTF-8 encoding. Inside it, marked strings like "-- JAHSHAKA SCENE FILE --" help identify it, and tags or fields such as "JAHSHAKA JAH_VERSION", "XML_FILE_VERSION", "SCENE_FILE NAME", "JAHLAYER", and "MEDIA" outline the content structure: defining Jahshaka version, scene metadata, layers, included media references. Only Jahshaka is known to create or read this particular scene file format.
