ReplaymodForge

 ReplayMod for NeoForge is an unofficial NeoForge port of the popular ReplayMod (https://www.replaymod.com/). The
  original mod only supports Fabric, so this port brings full replay functionality to NeoForge players.

  What it does:
  - Records your Minecraft sessions automatically in the background
  - Lets you replay recordings from any perspective — fly around freely, spectate any player
  - Set up smooth camera paths between keyframe points
  - Render replays to video for content creation
  - Works alongside other mods — records items, entities, and world events from all installed mods

  Requirements:
  - NeoForge (see version list for supported MC versions)
  - Client-side only  does not need to be installed on the server

  Notes:
  - This is an unofficial port, not maintained by the original ReplayMod team
  - For the original Fabric version, visit replaymod.com (https://www.replaymod.com/)
