TTML and WebVTT (ABR) Output Captions

Where to Specify the Captions

Put your captions in the same output group but a different output from your video.

After you add captions to an output, delete the Video and Audio 1 groups that the service automatically created with the output. To do that, pause on Video, and then choose the X that appears to the right. Repeat for Audio 1.

How to Specify Multiple Languages

Put each captions language in its own output.
