CallMarcus

CallMarcus is an independent software publisher distributing its work through GitHub, with a catalog currently focused on a single specialized utility for drone videography workflows. The publisher's product, DJI Metadata Embedder, addresses a common post-production challenge faced by drone operators, aerial videographers, and surveying professionals: preserving and integrating the telemetry information captured during flight. DJI drones record flight data such as GPS coordinates, altitude, speed, gimbal orientation, and camera settings into separate SRT subtitle files that accompany the captured footage, but this data is typically detached from the video itself. DJI Metadata Embedder solves this by embedding the telemetry data from these SRT files directly into MP4 video files, producing a self-contained media asset in which flight information travels with the footage. Typical use cases include professional aerial cinematography, where telemetry overlays add production value; inspection and surveying work, where location and altitude data must remain linked to visual evidence for documentation and compliance; and mapping or photogrammetry pipelines that benefit from synchronized positional metadata. The tool also serves hobbyist pilots who wish to archive their flights with complete flight-path information intact. As an open-source project hosted on GitHub, the software can be inspected, modified, and integrated into larger automated workflows, making it suitable for both individual creators and organizations building custom drone data processing toolchains. CallMarcus's catalog exemplifies the category of narrowly scoped, purpose-built utilities that solve a well-defined technical problem within the broader ecosystem of UAV (unmanned aerial vehicle) software, complementing editing suites, flight log analyzers, and geospatial data tools commonly used alongside drone-generated media.
