Screenberry v3.3 Release Notes

New Features

macOS Support

Screenberry now runs on macOS. Mac users gain access to powerful Screenberry features with native support for the Mac platform.

Improved Uncompressed Sequence Playback

The playback for uncompressed sequences has been significantly optimized. The media server now makes better use of hardware resources, enabling the smoother playback of TGA, TIFF, and DPX image sequences in higher resolutions and with higher frame rates.

Dedicated GPU for TouchEngine

The TouchEngine node now allows users to select a specific GPU for TOX rendering. This enhances consistency, improves rendering speeds, and optimizes overall performance by leveraging users' specific hardware configurations.

Advanced Color Management

The new Color Space Transform node utilizes the OpenColorIO library to apply accurate color space transformations, enhancing visual consistency and fidelity across different types of media.

Occluded Area Calibration

Automatic camera-based projection alignment is now possible even when the calibration camera’s view is partially obscured by objects between the camera and the screen. Objects can be masked before calibration, and the algorithm will reconstruct the image for the obstructed screen areas using data from adjacent sections of the screen.

Global Undo Stack

A global Undo Stack has been implemented along with a dedicated Undo History widget to track and manage changes more efficiently. New keyboard shortcuts have been introduced: Ctrl+Shift+Z is now available for redoing actions (Ctrl+Y also remains functional).

Hot Backup

A new Hot Backup node has been added that manages the synchronization of project data and mirrors control commands from the Panel to the backup server.

Redesigned 3D Scene

Enhanced Toolbar with New Tools

The redesigned toolbar now includes Move, Rotate, and Scale tools for the precise manipulation of 3D objects within the scene, improving user interaction and experience.

Improved Navigation Experience

New navigation tools such as the Fly, Pan, Orbit, and Zoom modes provide comprehensive control over viewport navigation, making scene interaction more intuitive.

Objects Lock and Hide

Lock and hide objects within the Scene Inspector pane, facilitating the simpler and more efficient management of scene elements by securing objects from accidental modifications and decluttering the view.

Ortho Viewports

Orthographic camera views have been introduced, which are essential for tasks that require more precision and clarity. These views complement the perspective view, which offers a more realistic representation of how objects appear in the real world.

Enhanced Pose Estimation

The pose estimation algorithms have been reworked, enhancing accuracy. Accessing the pose estimation functionality has become more intuitive. Point selection is now possible when using a free camera in pose estimation tasks.

Projection Simulation Mode

A new experimental Projection Simulation mode has been added, allowing users to conduct projector studies and preview a projection within the 3D scene.

Axis Indicator

An axis indicator is now displayed on the bottom left of the 3D viewport, providing a constant reference for spatial orientation within the scene.

New Shortcuts

Keyboard shortcuts have been added for all navigation and object interaction features within the 3D Scene, enabling quick and easy access to these tools and functions. For more detailed information, refer to the Working in the 3D Scene section.

Media Player Improvements

High Bit-Depth Audio Support

The Media Player now supports 24-bit and 32-bit audio, enabling uploads in their original native sample format to preserve audio quality.

AUX Audio Inputs

AUX audio inputs have been integrated into the Media Player node for the independent handling of multiple audio sources. Users can now rename AUX inputs for better management.

Media Player Copying with Content

When a Media Player node is copied, all the associated playlists and media they contain are copied with it. Additionally, restoring a deleted Media Player node using the Undo action also recovers all its content.

Item Replace Feature

This feature allows users to replace media items in playlists or timelines while preserving all the settings of the original media item.

Timeline Improvements

The ability to duplicate tracks on the timeline has been introduced, simplifying content replication and enhancing editing workflows.

The timeline view options have been expanded. Users can now select from three track heights: the default wide tracks, medium-height tracks, and narrow tracks. Updated video thumbnail display options allow users to show preview frames continuously, display just the first and last frames, or hide preview frames completely.

Matrix-based Playlist Improvements

Users can now duplicate, insert, move, and rename rows and columns, getting extended control over matrix layouts for precise content placement and adjustments.

The Ignore button has been added to the row header, enabling users to exclude specific rows when the particular column playback is started.

The Reveal Currently Playing Row Item button is now available, allowing users to quickly identify the currently active item in the row.

System Info Widget Redesign

Screenberry's System Info widget has been redesigned to provide more comprehensive system data along with new controls for GPU fan management.

Automatic Project Saving

Screenberry now features an option to automatically save projects when the Screenberry Server application is being closed.

Auto Save Project Settings

In Preferences, users can set intervals at which to automatically save the current project.

Reverting to the Saved Project

The File Menu now includes a Revert to Saved option, allowing users to easily revert their projects to the last saved state, thus safeguarding against accidental changes and unwanted modifications.

Text Rendering Enhancements

The Text Image node settings now include options for background color and shadow, providing additional customization capabilities for displaying text.

Gamma Correction Node

A new (experimental) Gamma Correction File node has been added, allowing users to load T3D files for precise gamma correction. This node enables the accurate adjustment of brightness and color balance by applying custom Look-Up-Tables (LUTs), ensuring accuracy and consistency across different projectors during calibration.

Parent Calibrator Parameter

The Parent Calibrator Patch input parameter has been added to the Calibrator node, allowing multiple Calibrator nodes to connect directly to simplify multi-camera calibration setups.

Rectangle Patch Circular Mask Option

The Rectangle patch now includes a Circular Mask option, allowing the creation and manipulation of circular shapes.

Shape Patch Warp Feature

An experimental feature has been added to the Shape Patch, enabling users to warp rectangular shapes using manually placed points. This feature allows for more flexible and customized shape manipulation.

Audio Analyzer

A new Audio Analyzer node allows for the visualization of the audio spectrum of the incoming audio.

Media Library Update

The Main Server menu now includes the Rescan Media action for refreshing media content associated with the project.

Timecode Offset

An Offset parameter has been added to LTC and MTC Decoders, allowing users to customize timecode offsets.

New Equal Nodes

A range of new Equal nodes for various data types has been introduced including Float, Int, Vec2, Vec3, Vec4, IVec2, and String, streamlining node setups when performing data comparisons.

New Round Node

A new mathematical Round node has been added that’s specifically intended for rounding input double-precision floating points.

Render Target Reference Image Input

A new Reference Image input parameter has been added to the Render Target node, allowing users to utilize images received from other nodes as references within the Patch Editor, thus enhancing the accuracy and ease of content creation.

Accessing the User Control Widget

Double-clicking any node related to user controls (Button, Checkbox, etc.) now opens the User Control widget.
