To have a real-time subtitling overlay, you need to select the source file from the Library and then go to the “File info” menu and click on the ”Subtitling” sub-menu. Upload the SRT file by clicking in the window. Remember that the source file timecode has to match the timecode in the SRT file.
You can see the attached SRT here, and in the player window, you have the icon for subtitling where you can select the different languages. You can add as many SRT/ languages files as you need by using the “+” icon and remove them by the “-“ icon.
You can rename the upload SRT to change what will be displayed in the Subtitling player window just by clicking on the title window.
The language menu is to select the right language for auto-detection within your browser.
