GitHub - eggricesoy/filmkit: Create and manage Fujifilm camera profiles, with ease and speed. Connect your camera and you are good to go!

FilmKit is a browser-based, zero-install preset manager and RAW converter for Fujifilm X-series cameras. It uses WebUSB and PTP (Picture Transfer Protocol) to communicate directly with the camera, letting the camera's own image processor handle RAW-to-JPEG conversion. Features include reading/writing camera presets, a local preset library with drag-and-drop, live preview, preset detection from RAF files, and mobile support. The protocol implementation was reverse-engineered using Wireshark USB captures and open-source references. Currently tested on the X100VI, with community help sought for other X-series models via Wireshark capture contributions.
