Video filters can be applied to any Source or Scene by right clicking on the title and selecting Filters. New Filters can be added to OBS when specific plugins are installed. Similar to Sources, Filters can have their visibility toggled on and off in the Filters management window. By default, OBS organizes Filters into Audio/Video Filters and Effect Filters. You can add a filter by selecting the “+” plus button, which will open the Filter and allow you to adjust the Filter settings. There is a plugin called OBS Filter Hotkeys that will allow you to toggle the visibility on and off for Filters using Hotkeys without having to open the Filters management window.
