No FFmpeg installation found: Ensure ffmpeg.exe is in the .minecraft folder. If using a custom launcher (MultiMC, GDLauncher), place it in the specific instance's .minecraft folder.
Crash while rendering: This is usually caused by invalid Command Line Arguments or unsupported resolutions. Reset to "MP4 - Default Quality" and try again.
Shaders Compatibility: Replay Mod is compatible with Iris and Sodium. If using shaders, ensure they are enabled before starting the render process.
Frequently Asked Questions
How long can I record? Theoretically up to 24 days of continuous footage.
Does recording cause lag? Recording world data is significantly less taxing than recording video. Most players will notice zero impact on FPS.
Can I record on servers? Yes. The mod records all data sent by the server to your client. It does not record chunks that the server hasn't sent to you (outside your server-side view distance).
