How to use Replay Mod is easier to learn as a workflow than as a list of buttons. Every project follows the same path: record a session, open it in the Replay Viewer, place camera keyframes and render the result. Once that loop makes sense, every advanced feature slots neatly into it.
Recording a Session
Recording is configured in the mod's settings, where separate options control recording in singleplayer worlds and on servers. With recording enabled, the mod captures your session while you play, and the replay is saved when you leave the world.
- Check the recording options before an important session.
- Play normally, because the camera can be changed later.
- Leave the world properly so the replay finishes saving.
- Find saved replays in the
replay_recordingsfolder.
Recording on servers
Replay Mod runs only on your client, so you can record on many servers. Some servers restrict certain features, so respect each server's rules about recording.
Opening the Replay Viewer
A Replay Viewer button appears on the main menu once the mod loads. It lists your saved replays, where you can load, rename or delete them. Loading a replay places you inside the recorded world as a free camera.
| Control area | What it does |
|---|---|
| Free camera | Fly through the recorded world from any angle |
| Timeline | Jump to any moment of the session |
| Speed control | Slow down or speed up playback |
| Keyframe tools | Mark camera positions and times for a path |
Exploring and Reviewing Footage
Fly around the scene and scrub through the timeline to find the moments worth showing. Slowing playback helps when reviewing fast action, while pausing lets you frame a shot calmly before adding keyframes.
The mod's event markers can flag moments in a recording, making long sessions easier to navigate. Marking highlights during review saves time when you plan several shots.
Placing Keyframes
Camera paths are built from keyframes. A position keyframe stores where the camera is and where it looks, while a time keyframe stores which moment of the recording plays at that point. Combining both controls camera movement and the flow of time.
- Place the first position keyframe where your shot begins.
- Move the camera and the timeline, then add the next keyframe.
- Preview the path and adjust any keyframe that looks rough.
- Use time keyframes to create slow motion or timelapse effects.
Rendering Your Video
Once the path looks right, open the render settings. Choose an output preset, resolution and file location, then start the render. FFmpeg must be installed for this step, as the documentation explains in its installation section.
Rendering processes the path frame by frame, so longer clips and higher settings take more time. A short test render shows whether the motion and quality match your expectations before a full export.
Building Good Habits
A few habits make every project smoother. Keep recordings organized by naming them clearly in the Replay Viewer. Back up important replays, since they are the raw material for future videos.
- Plan shots before placing many keyframes.
- Keep paths smooth with evenly spaced keyframes.
- Render short tests whenever you change settings.
- Keep your mod and FFmpeg installations updated.
Understanding the Main Settings
Replay Mod settings control recording behavior, replay playback and rendering defaults. Spending a few minutes in these menus before your first project avoids surprises later.
| Setting area | What it controls |
|---|---|
| Recording | Whether singleplayer and server sessions are recorded |
| Replay | Playback behavior and camera options |
| Keyframes | Interpolation and path behavior |
| Rendering | Output defaults used in the render screen |
Planning Your First Project
A short, simple project teaches the workflow faster than an ambitious one. Record a few minutes of building or exploring, then aim for one smooth camera move and a short render.
Writing down three planned shots before opening the Replay Viewer keeps the session focused. Each shot needs a starting point, an ending point and a reason for the viewer to watch it.
- Pick one location with interesting scenery.
- Plan a slow, steady camera move.
- Render a short clip and review it on another device.
Working With Recorded Players
Recorded players appear in the replay just as they moved during the session. The camera can follow them, frame them from the side or watch from a distance, which makes recorded action far more flexible than first-person footage.
Rendering Checklist
Running through a short checklist before each render prevents wasted time. Most failed renders come from a missing step rather than a real bug.
- FFmpeg is installed where the game can find it.
- The camera path has been previewed from start to finish.
- Output resolution matches where the video will be published.
- The output folder has enough free disk space.
Sharing Your Work
Finished renders can be uploaded like any other video file. Replay files themselves can also be shared with collaborators who use the same mod setup, allowing a teammate to pick their own shots from your session.
Keeping replays after rendering is worthwhile. Returning to a recording months later lets you create new edits or higher-quality renders without playing the session again.
Learning Advanced Features
Once the basic loop feels comfortable, explore 360-degree rendering, spectator keyframes and creative time effects. Each feature builds on keyframes and rendering, so the skills you already have transfer directly.
Mistakes Beginners Often Make
A few early mistakes are very common, and each has a quick fix. Knowing them in advance shortens the learning curve noticeably.
- Forgetting to check recording settings before an important session.
- Quitting the game abruptly, which can prevent a replay from saving properly.
- Placing keyframes too close together, causing jerky movement.
- Starting a long render without a short test first.
Avoiding these four mistakes covers most problems new users report, and the remaining issues are usually solved by checking FFmpeg placement or the mod loader profile.
Conclusion
How to use Replay Mod comes down to one repeatable loop: record, review in the Replay Viewer, build a path with keyframes and render with FFmpeg. Practising that loop with short clips builds confidence quickly.
After a few projects, advanced options such as 360-degree rendering and complex time effects feel like natural extensions of the same workflow.
