What is a G3 file?

G3 files mostly belong to GoPro Player.

File Purpose: G3 files serve different functions depending on their origin. They may contain JSON-formatted video metadata for GoPro devices, hold raw fax image data, or store game data used by arcade systems.

Video Metadata: These files carry metadata (like camera settings and time codes) in JSON format. They work with GoPro Player or GoPro Studio and may support Logitech webcam recordings.
Fax Image Data: Some G3 files are used to store raw fax image information. Programs such as GIMP can open these images.
Game Data: Other G3 files are used for storing game data files by engines like PlayMechanix Wave Engine, as seen with arcade titles such as Big Buck Hunter Pro. More details can be found on the RawThrills website.

FilExt.com tip: Identify the source of your G3 file to choose the correct tool for viewing or editing it.
