VOID is a player, a growing review system.

This project is a media player designed for playback and management of visual media files. As development progresses, it aims to evolve into a full-fledged review system—enabling users to view, analyze, annotate, and provide feedback on media content.

The player is cross-platform and currently supports Linux, Windows, and macOS. Ongoing development will continue to target all major platforms.

Below are a few screenshots showcasing its early interface and capabilities.

• Multi project support for Media
• Drag-and-drop support for directories
• Automatically builds structured playlists from media folders
• In-project multi playlist support for further grouping media for quick review & playback

Supports a wide range of media formats:

• Images: PNG, EXR, JPG, TIFF, DPX, and couple more via OpenImageIO
• Videos: MOV and MP4—enabled via FFmpeg

The player also supports media reader plugins, allowing developers to extend format support by writing custom plugins. An example plugin is available here

• Standard playback controls: Play, Pause, Seek, etc.
• Dual-buffer playback: A/B buffers for simultaneous media handling

Dual-buffer mode enables rich media comparison using multiple viewer layouts:

• Horizontal & Vertical Split
• Swipe Compare
• Stack Compare

Blend modes are currently under development.

• Add annotations directly on media for review and feedback
• Useful for collaborative workflows and visual notes

Annotation export is not yet implemented. Exporting annotated frames will be supported once the media writer system is integrated.

Customize player behavior with basic preferences:

• Default media view interface
• Customization of the color scheme
• Handling of missing frames
• Undo history settings

Support for scripting on the player using python bindings.

VOID provides internal API via vortex python binding, allowing interaction with internal components of the system
