Edit caption properties in Compressor
You can edit caption content, placement, formatting, and timing in the Closed Captions
inspector (for jobs that contain CEA-608 closed captions) or Subtitles inspector (for jobs
that contain iTT subtitles or SRT subtitles). Because CEA-608, iTT, and SRT captions have
different specs, each Compressor inspector contains slightly different controls.
Specify the caption language properties
Before transcoding, you need to specify the language and country of the captions. For iTT
subtitles, you must also choose a subtitle type (or “purpose”).
1. In the Closed Captions inspector or Subtitles inspector in Compressor, choose options
from the Language pop-up menu and Country pop-up menu.
Tip: You must choose a language before you can choose a country. If you don’t
choose a language and country, your transcoding job won’t process.
2. For iTT subtitles only: In the Subtitles inspector, click the Purpose pop-up menu and
choose a subtitle type:
• Translation (Full): Use for a full translation of all words spoken in the video (in the
language you chose in step 1). During playback, viewers can turn these subtitles on
or off.
• Forced: Use when a person in the video speaks a language different from the main
language of the video—for example, for a French speaker in an otherwise English-
language film. Forced subtitles can’t be turned off because they’re necessary to
understand the content of the video.
• Deaf and Hard of Hearing (SDH): Use for a full translation of all the words spoken
in the video, as well as for song lyrics and sound effects (owl hooting, scream in
distance, and so on). During playback, viewers can turn subtitles for the deaf or hard
of hearing (SDH) on or off.
Choose an animation style (CEA-608 closed captions only)
The CEA-608 format allows for several different styles of caption animation.
1. In the Captions list at the bottom of the Closed Captions inspector in Compressor,
select one or more captions.
Each line in the list, which represents a single caption, displays the caption’s timecode
start point, end point, and text.
2. In the Formatting area of the Closed Captions inspector, click the Caption Style pop-up
menu, then choose an option:
• Pop-On: The caption appears suddenly on the screen at the caption’s timecode start
point. If multiple captions overlap in time, they’re stacked vertically onscreen, with
each new caption appearing beneath the previous caption.
