Getting Started with V-Nova PresenZ Player

Use V-Nova PresenZ Player to build and view PresenZ shots and sequences in VR. The player supports basic finishing adjustments and performance monitoring. Use its overlays and graphs to diagnose playback and rendering issues.

Introduction

V-Nova PresenZ Player is a compact application for building and viewing PresenZ-based VR shots. It provides utilities for working with PresenZ files. It also includes performance graphs for diagnosing issues and improving playback.

Features

• View PresenZ content in VR

• Manage files with drag and drop

• Monitor performance with visual graphs

• Apply basic post-processing adjustments

• Customise a focused user interface

Supported media

The primary media type is .prz. This losslessly compressed format is generated from .przRender files. It supports efficient playback in the player. The player supports these file types:

PresenZ formats

• .przShot

• .prz

Background images

• .png

• .jpeg

• .pitex

• .exr

Background video

• .mp4 (HEVC)

Audio

Movie

Open and load media

Load media by dragging files into the workspace. Alternatively, select Movie → Open. The file browser lets you add files or open a .przToc file for editing.

Builder

Use the Builder to create and test shots. It automatically adds files dropped into the workspace. The Builder saves the scene as a .przToc file. See File formats and structures in V-Nova PresenZ for file-type details. The Builder header shows the file location and common directory.

Added files appear in the Files section. Assemble the shot in the Scene section. This layout reflects the PresenZ three-stage construction. Drag files into the appropriate section.

Movie info

View the number of frames and scenes, the current position, and file locations. Use this window to quickly identify sequence and frame numbers when investigating artifacts.

Scene info

View information about the current scene. Create, remove, and switch scenes in the Builder. You can also use keyboard shortcuts.

Frame info

View the current layers, particle counts, motion vectors, compression, and format.

View

Keys

View the current keyboard shortcuts.

Playback

Control shot playback speed and switch scenes.

Log

View information about actions in the scene. Some tools send diagnostic data here.

Display colours

View and change colour settings to match the input material.

About

View the installed V-Nova PresenZ Player version.

Inspect particles

Use this window with motion vectors to inspect particles and asset density. Enable the debug sky to replace the background with bright purple. This helps confirm that the PresenZ render contains complete geometry.

Adjust scene

Make scene-level adjustments that persist until you reopen the movie. Rotate a background HDRI and adjust sound positioning. You can also set the viewing perspective before playback. This lets you position and rotate the VR agent away from the origin.

Post-processing

Apply minor effects and adjustments to every scene. Available controls include fog, glow, brightness, and depth of field. These settings persist until you reopen the player.

Shader tweaks

This developer feature supports adjustments to custom shaders in the player. It is covered in the advanced documentation and is not intended for standard use.

Camera position

Copy values between cameras. This helps maintain a consistent viewpoint between shots and avoids jarring cuts. Use it to check the current camera position across multiple shots.

Performance

Frame loader

View the frames currently loaded in the buffer and the playback frame rate. If the top bars reach the warning lines, the decoded-frame buffer may decrease.

Audio

View the current audio and its load time. Use this information to diagnose sound issues.

Rendering

View the current render speed and active processing. Use the graph to analyse dropped frames and slow playback.

Frame Graph

View the high, low, and average playback frame rates. You can also send this information to the log. The window shows the number of accumulated frames at the top. Enable Report to log, then use Pause to capture data between log entries.

GPU Memory

View current GPU memory usage, broken down by section.
