Video Sync Controller is a free Chrome extension developed by bnjmnnrtn. It falls under the category of Browsers with a subcategory of Add-ons & Tools. The program allows users to pause and play local videos across a virtual private server.

The extension, along with a Python VPS/WebServer and JS Chrome extension, synchronizes the playing of local movie files. To use the Chrome extension, users simply need to click "Start" in the extension, input the VPS IP and Port 2023, and then either host or connect to a room.

Hosting a room gives the user control over the video position and whether it is paused or not. The host also determines which video file will be available to clients. Users can download video files by clicking on the "Download" button and selecting the desired file from the "Video Input" field. Once downloaded, the video will appear below.

For those hosting a room, they can upload a video file by selecting it in the "Video Input" menu and pressing "Upload."

Overall, Video Sync Controller is a useful tool for those looking to synchronize the playback of local videos across a virtual private server. With its simple interface and easy-to-use features, it provides a convenient solution for managing and sharing videos remotely.
