Convert MCPR to MP4

Source format

MCPR is a Minecraft replay recording format used by the Replay Mod for Minecraft Java Edition. It stores replay data such as player movement, camera paths, world state, and timing information. It is not a finished video file, so it cannot be opened like an MP4 in a normal media player.

Target format

MP4 is a widely supported video container format used for playback, editing, sharing, and uploading on most devices and platforms. Unlike MCPR, MP4 is a standard video file that can be played without Minecraft or Replay Mod.

Can you convert MCPR to MP4 directly?

No. An MCPR file cannot be directly converted to MP4 by a normal file converter because it does not contain encoded video. The replay must first be opened in Minecraft with Replay Mod, then rendered into video frames or exported as a video file.

How to convert MCPR to MP4

1. Install Minecraft Java Edition and the Replay Mod version that matches your Minecraft version.
2. Make sure the .mcpr file is in the Replay Mod replay folder, or import it if your setup supports that.
3. Launch Minecraft with Replay Mod installed.
4. Open Replay Viewer and select the replay.
5. Set the camera path, resolution, frame rate, and quality options.
6. Use Replay Mod’s Export or Render function to create the video output.
7. If Replay Mod offers MP4 export in your version, save it as .mp4. If it exports image frames instead, encode those frames to MP4 with a video encoder such as FFmpeg.

Example FFmpeg command for numbered PNG frames:

ffmpeg -framerate 60 -i frame%06d.png -c:v libx264 -pix_fmt yuv420p output.mp4

Recommended tools

Replay Mod is the best tool for working with MCPR files because it understands the replay format natively. FFmpeg is the best companion tool if you need to encode rendered frames into MP4. For recording live gameplay instead of replay rendering, reputable desktop recorders such as OBS Studio are a better choice than file converters.

Online converters are not suitable for MCPR files because they cannot interpret Minecraft replay data. If a website claims to convert MCPR to MP4 directly, it is likely misunderstanding the format or offering a screen-recording workaround rather than a true conversion.

Quality and compatibility notes

The final MP4 quality depends on your Minecraft graphics settings, camera work, frame rate, and export settings. Higher resolution and frame rate produce smoother results but take longer to render and create larger files.

Compatibility also depends on the Replay Mod and Minecraft versions used to create the replay. If the replay was recorded with a different version, it may not open correctly. For best compatibility, export MP4 using H.264 video and yuv420p pixel format.

When to use a screen recorder

If you only need a quick video of a replay and do not want to render it inside Replay Mod, you can play the replay back in Minecraft and record the screen with OBS Studio, Bandicam, or similar software. This does not convert the MCPR file itself, but it does produce an MP4 video that can be shared immediately.
