FAQ

Frequently Asked Questions

Common questions regarding VideoSync Studio network setup, kiosk displays, and audio ducking.

No. Once installed, VideoSync operates 100% locally across your Wi-Fi router or wired local network (LAN). Internet is only needed if you choose to stream live YouTube links or download new videos from YouTube.

When you click "Start Speaking" on the Admin Panel (from the Server PC or your smartphone), VideoSync automatically signals all connected client screens to smoothly fade their video volume down to 15% (or full mute). Your live voice streams with ultra-low latency to venue speakers. When you stop speaking, background music seamlessly restores to normal volume.

There is no software limit. VideoSync Studio supports unlimited client displays across your local network. A standard gigabit router can comfortably sync 30+ Full HD screens simultaneously with zero buffering.

The VideoSync Client installer configures Windows auto-login and unattended boot. When the client PC turns on, it automatically launches the dedicated full-screen kiosk, connects to the server, and locks into the current video stream in sync with all other screens!

Yes. VideoSync Studio is 100% free freeware developed by Buddy Technical Solution (ebuddy.lk). There are no per-screen monthly fees, no cloud subscription bills, and no hidden limitations.
