ReplayView: Free Camera and Replay Controls for NFS4 High Stakes

ReplayView is a module for Need for Speed: High Stakes that adds a free camera, vehicle tracking, replay rewind and fast forward, and custom camera presets.

The module works through the n4patch system, so there is no need to modify nfs4.exe.

Version: 0.7.4 Module file: replayview.n4p
SHA256: f303ca5828969adf6b9bd5aa940aad169eed3855154d94dfda9fcec2ef3189ef

Features

• Free Camera: Move freely around the track in any direction using the keyboard and mouse.
• Vehicle Tracking: Make the camera follow a selected car, match its rotation, or combine both modes.
• Replay Rewind and Fast Forward: Return to earlier moments of a race and navigate through individual simulation ticks.
• Camera Presets: Save up to 10 custom camera angles for each track.
• Movement While Paused: The free camera remains fully controllable even when replay playback is paused.
• Customizable Controls: Adjust key bindings, movement speed, and mouse sensitivity.

Installation

Step 1: Install the n4patch Loader

ReplayView requires the n4patch loader.

If you have not installed it yet, download it and follow the installation instructions:

https://nfs4.com/mods/n4patch-loader

The recommended loader is version.dll.

If your game already uses version.dll, choose another supported loader DLL.

Step 2: Install ReplayView

Copy replayview.n4p into the patches folder inside your game directory.

Copy replayview.ini into the same folder as nfs4.exe.

Example folder structure:

NFS4/
  nfs4.exe
  version.dll
  replayview.ini
  patches/
    replayview.n4p

The replayview.ini file is optional. If it is missing, the default settings will be used.

Step 3: Start the Game

Launch NFS4 normally.

The loader will automatically detect and apply replayview.n4p.

If the module does not work, check n4patch.log in your game directory.

How to Activate Free Camera

1. Start a race and enter Replay mode.
2. Cycle through the available cameras until you select Camera 7.
3. You can now move the camera freely using the keyboard and mouse.
4. Press L to switch to the next replay camera and exit Free Camera mode.

By default, Free Camera is available only during replay playback.

While Free Camera is active, moving the mouse will not cause the replay control panel or in-game cursor to appear.

Free Camera Controls

Key	Action
W / S	Move forward / backward
A / D	Move left / right
R / F	Move up / down
Mouse	Rotate the camera horizontally and vertically
Q / E	Camera roll
Shift	Move 3 times faster
Ctrl	Move 12 times faster
L	Next replay camera (exit Free Camera)
Space	Pause / resume playback

When Shift and Ctrl are held simultaneously, the Ctrl speed multiplier takes priority.

Tip: Use Ctrl to move quickly between distant parts of the track, and Shift for more precise camera positioning.

Vehicle Tracking

ReplayView allows you to attach the camera to any car participating in the race.

Key	Action
Z / X	Switch between vehicles
V	Toggle position tracking
C	Toggle rotation tracking
B	Move the camera behind and slightly above the selected vehicle

Position Tracking (V)

When position tracking is enabled, the camera moves together with the selected vehicle.

Its relative position is preserved. For example, if the camera is positioned beside the car, it will remain beside it as the car turns.

You can still use WASD, R, and F to adjust the camera's position relative to the vehicle.

Rotation Tracking (C)

When rotation tracking is enabled, the camera follows changes in the vehicle's orientation.

The mouse and Q/E keys remain active, allowing you to adjust the viewing direction without disabling tracking.

Example: Creating a Custom Chase Camera

1. Select a vehicle using Z and X.
2. Press B to move the camera behind the vehicle.
3. Press V to make the camera follow the car.
4. Press C to make the camera follow its rotation as well.
5. Adjust the distance and viewing angle using the keyboard and mouse.

This allows you to create your own chase camera variations, side views, overhead shots, or almost any other perspective.

Replay Rewind and Fast Forward

In the original NFS4, replays are played back by re-simulating the race. ReplayView adds the ability to return to earlier moments using saved snapshots of the game's simulation state.

Rewind and fast forward work with any replay camera, not just Free Camera.

Keys	Action
, / .	Backward / forward by 1 tick (1/64 second)
Shift + , / .	Backward / forward by 1 second
Ctrl + , / .	Backward / forward by 10 seconds
Space	Pause / resume playback

When a rewind or fast-forward key is held down, automatic key repeat starts after one second.

If you fast-forward beyond the recorded snapshot history, ReplayView uses accelerated simulation to reach the selected point.

Rewind Buffer Size

By default, ReplayView stores 768 ticks, corresponding to approximately 12 seconds of replay history.

With visual effect snapshots enabled, this buffer requires approximately 130 MB of RAM.

You can increase the history buffer size in replayview.ini, but longer recording periods require more memory.

You can also customize the rewind step sizes and automatic key repeat intervals.

Limitations: Some audio and visual effects may not be restored perfectly. Rewind is still an experimental feature.

Camera Presets

ReplayView allows you to save up to 10 custom camera configurations per track.

This is especially useful for creating videos when you need to switch quickly between predefined camera positions.

Keys	Action
Ctrl + 0–9	Save the current camera configuration
0–9	Load a saved camera preset

How to Save a Camera Preset

1. Enter Free Camera mode.
2. Position the camera and adjust its viewing direction.
3. Optionally enable vehicle tracking using V and C.
4. Press Ctrl and any number key from 0 to 9.
5. To return to that camera configuration, simply press the corresponding number key.

Camera position, orientation, and vehicle tracking settings are saved.

Presets are stored in:

Data\Tracks\<track_name>\freecam.ini

Each track has its own set of 10 presets. These settings are preserved between game sessions.

If the vehicle associated with a saved preset is no longer available, the last available vehicle will be used instead.

Configuring replayview.ini

The replayview.ini file should be placed next to nfs4.exe.

It allows you to customize:

• Camera control keys.
• Normal and boosted movement speeds.
• Mouse sensitivity.
• Camera position when teleporting to a vehicle.
• Rewind buffer size.
• Rewind and fast-forward step sizes.
• Automatic key repeat intervals.
• Visual effect snapshots during rewind.

For example, RewindTicks determines how many simulation ticks are stored in the rewind history.

Setting Rewind=0 completely disables snapshot recording and rewind controls.

To reverse a camera movement direction, you can swap the corresponding key assignments in the configuration file.

If the configuration file is missing, ReplayView uses its default settings.

Known Limitations

ReplayView is still under development, so some features have limitations:

• By default, Free Camera is only available during replay playback.
• Field of View (FOV) adjustment is not currently supported.
• Rewind does not guarantee complete restoration of all audio and visual effects.
• Compatibility depends on the version of nfs4.exe and the n4patch loader.

Uninstalling ReplayView

To disable the module, remove or move replayview.n4p from the patches folder.

You can also delete replayview.ini if it is no longer needed.

Saved freecam.ini camera presets can be kept for future use.

There is no need to modify or restore nfs4.exe.

Known Issues

• Stuck AI Horn: During fast-forward, an AI car's horn may occasionally get stuck and continue playing until the replay is restarted.
• Camera Preset Hotkeys (1–3): Using camera presets assigned to keys 1, 2, or 3 also triggers the game's audio messages.
