How the Add Subtitles Endpoint Works

The /api/add_subtitles endpoint offers a straightforward method to burn ASS/SSA subtitles into a video. To use this endpoint, you need to provide the video URL and the subtitle file URL. The API will download both files and integrate the subtitles into the video.

Additionally, you can choose to process this task in the background by setting the async parameter. This is particularly beneficial for lengthy videos, allowing you to retrieve a job ID and check back later for completion.
