The Khronos Group developed GLB files as a format for storing complex 3D models. The format was first introduced in 2015 and aimed to create a format that could be easily adopted by third-party developers. Subsequent versions have followed this initial release, adding more complex features.
Support for GLB files is growing and has found support in many modern 3D model editors, such as Blender, which currently supports importing from and exporting to the GLB format.
Mesh Geometry
At the heart of the GLB format is its ability to store 3D geometric mesh data, which comprises vertices, faces, normals (both face and vertex normals), and texture coordinates. The data is saved in a compact binary format, ensuring GLB files are compact and easy to distribute.
GLB Converter Capabilities
As materials containing texture and color information are both supported by the GLB format, our tool will do its best to include these materials, including any texture files, in the converted file.

A VID file is a video file format native to the ZX Spectrum Next. It stores uncompressed video as a sequence of images along with 8-bit audio. The only currently supported resolution of the video is 320x240 in 256 colors at around 16.6 FPS. For additional technical information, please see the Spectrum Next developer portal.
The VID format supports additional resolutions and framerates, which may or may not include a separate palette per frame. The conversion currently supported is for 320x256 resolution only, with a palette per frame.
