Add your SRT or VTT subtitle file to the video, burned in or as a separate track.
You can upload subtitle files in SRT or VTT format.
Burning in permanently renders the subtitles into the video — visible in every player but can't be turned off. A separate track can be toggled on or off if the player supports it, and the video picture itself stays unchanged.
No, it's only supported for MP4 and MOV targets. If you choose WEBM, subtitles are automatically burned in instead.
