In computer science and AI research (such as the UCF101 or Kinetics datasets), video files are often renamed to short codes like "g01_v01.mp4" for easier processing.
Many DVR and NVR systems (such as those from Lorex, Swann, or Hikvision) auto-save clips using "g" (for group/channel) or "ch" prefixes followed by timestamps or sequence numbers. g4_0123.mp4
