There is only one file type that uses the .MD5CAMERA extension:
id Tech 4 Model Camera File
3D camera file used by id Tech 4, a game engine developed by id Software for Doom 3 and Quake 4; contains 3D camera paths, including the position, rotation, and field of view for each path; used for controlling cameras during cinematic sequences and cut scenes in id Tech 4 games.
MD5CAMERA files are stored in a plain text format. They are often packaged into id Tech 4 packages, which use the .PK4 extension.
NOTE: id Tech 4 is also known as the "Doom 3 engine."
