Important: using the beta

VTR-PON is a personal hobby project distributed free of charge. This beta is intended for people willing to help test its operation and report bugs.

As a beta under development, it may have bugs or behave unexpectedly. Stable operation at live events, during streaming, or in recording is not guaranteed.

The author accepts no liability for trouble, damage, or loss arising from use of this software, including use at live events. Use it at your own discretion and responsibility.

Before use, test it thoroughly with your actual PC, media, and video and audio outputs. Please share any issues using the contacts on the Development & feedback page.

Main features

Separate controls and output

The control and checking interface is completely separate from the fullscreen player, keeping controls out of your audience's view and delivering a clean media output.

Play video, audio, still images, PPTX and PDF documents, and live inputs such as UVC in fullscreen.
