Replay Mod is a Minecraft mod that allows users to create great-looking Minecraft videos in minutes. Recordings can be edited without any installing additional video-editing software, then shared with the community via the Replay Center. Replay Files are in a lightweight format - An average recording over 1 hour is less than 10 Megabytes large. You can easily share your Replays with your friends using the Replay Center. Coming with a built-in video creator, the Replay Mod allows everyone to make perfect clips without any external software.

+RoadHog Main so what I could guess is that another mod is present or left traces, you might want to make a backup of your.minecraft folder or just rename it, try a clean installation and it should work. My guess is one of your mods got injected in the main jar file or something else happened.

MadCat 馃幃 I also tried 1.9 but it didn't work as well. 1.12 worked but there was an error with the rendering.

+RoadHog Main but in your case it happened with the 1.8 version, I remember that one not being stable at all, also it could be that they used a different version of java even, there are many factors that could go wrong in old versions of the game.

the same happens to me, I read some threads but I don't understand it. I don't think it is because of Optifine but Replaymod itself, 'Description: Failed to load entity tracker, pathing will be unavailable.' It is saying that it failed to load entity tracker, and someone said in a thread you need to delete something in a zip folder of MCPR. Its stressing me out, can you please help us?
The Replay Mod

How to install:
- Download and install the correct Minecraft Forge 1.9.
- Run Minecraftonce to ensure that Minecraft Forge is installed correctly. A Mods button should now be available in the main menu.
- Download a copy of the Replay Mod jar (zip) and save it to the directory %appdata%/Roaming/.minecraft/mods. The modsdirectory is created by Minecraft Forge in the previous step.
- Run Minecraft and enjoy!
