DVB-Sub Output Captions

Where to Specify the Captions

Put your captions in the same output group and the same output as your video.

How to Specify Multiple Captions Tracks

  • If your input captions are the same format as your output captions (passthrough), you need to create only one group of captions settings. The captions selector that you choose under Captions source includes all tracks from the input.

  • If your input captions are in a different format, create one group of captions settings for each track. Put each group of captions settings in the same output. They will appear in the list of settings groups as Captions 1, Captions 2, and so forth. In each group of settings, choose the captions selector under Captions source that is set up for the track that you want to include.

How to Specify the Font Script

AWS Elemental MediaConvert automatically selects the appropriate script for your captions, based on the language that you specify in the output captions settings. If the language that you choose has more than one possible script, specify the script that you want.

To ensure that the service uses the correct font script

  1. In the Captions section under Encoding settings, for Language, choose the language of the caption text.

  2. If the language that you specify has more than one possible script, use Font script to specify the script.

    For example, if you choose Chinese (ZH) for Language, use Font script to choose either Simplified Chinese or Traditional Chinese. In this case, if you don’t specify a value for Font script, the service defaults to simplified Chinese.

    Tip

    In most cases, for Font script you can keep the default value of Automatic. When you do, the service chooses the script based on the language of the caption text.
