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
