Closed Captioning workflow in Premiere Pro
Premiere Pro CC provides a full set of closed caption features.
You can import closed caption files into Premiere Pro, and add them to a sequence. You can edit the closed caption text, color, background, and the timing. Once you finish editing, you can export the closed captions files as a closed caption "sidecar" file or embed them in a QuickTime movie file.
Premiere Pro lets you import:
- Stand-alone closed caption files or "sidecar" files
- Files with embedded captions
You can import media with closed captions into your project in Premiere Pro just like you would import any other media by using one of the following options:
- Select File > Import
- Import through the Media Browser using the file's context menu
- Import the Closed Caption clip as a separate Closed Caption "sidecar" file
If the file contains embedded closed captions, Premiere Pro imports the closed caption data automatically into the project. To detect and automatically import embedded closed caption data in an embedded closed caption file, select the preference to import the closed caption data into your project. In the Preferences dialog, under Media, select the Include Captions On Import check box.
When you import a QuickTime clip that contains embedded captions, the captions are automatically imported. If a QuickTime clip has an accompanying "sidecar" caption file, then you import the "sidecar" file just like you import any other file.
When you import closed caption clips into a project, the captions are displayed as caption blocks in the Captions tab.
To display the Closed Caption clips in the Source Monitor and Program Monitor, do one of the following:
- Click "+" at the lower right of a monitor to open the button editor, and click the Closed Captioning Display button. You can add the Closed Caption button to the button bar by dragging it from the button editor. You can also assign keyboard shortcuts to those commands.
- In the Source or Program Monitor panel pop-up menu, select Closed Captioning Display > Enable.
You can select the captioning standard for a caption clip loaded in the Source Monitor. In the Source Monitor panel pop-up menu, select Closed Captioning Display > Settings. For example, you can select CEA-608, CEA-708, CC1, CC2, and so on. You can toggle the Closed Caption display on and off.
The Closed Caption clip when linked to video behaves similar to a linked audio channel clip. The text clip is represented in the Timeline's source indicators, and can be enabled/disabled or linked to any video track like other video clips.
When a track is expanded, the Closed Caption blocks in a caption clip are visible, along with End Of Caption (EOC) indicators that denote where the Closed Caption blocks begin and end.
The Captions tab in Premiere Pro lets you make word-level edits of the closed caption clips. You can also make changes to the timing and formatting, like, text alignment, text color, from an intuitive user interface.
Example usage scenario
Consider a scenario where you have a program that already contains closed captions. You may need to create a different version of the program, say with a shorter duration, to add more commercials. In such a scenario, you can make the necessary edits using the Captions tab. The text clips are visible from the timeline. From there, you can adjust the captions to be in proper sync with the media after any trims, ripple deletes, and rearranging of segments.
After you finish editing or creating closed caption clips, you can do either of the following:
- Export the sequence containing the closed caption clip to tape using third-party hardware that support closed caption encoding.
- Export the closed caption tracks through Premiere Pro or Adobe Media Encoder using the Export Settings dialog. You can do so by following these steps:
In the Export Settings dialog box, specify the following options under the Captions tab.
Select one of the following export options:
- Create Sidecar File
- Embed in Output File
Select one of the following file formats to export the closed caption data:
- Scenarist Closed Caption File (.scc)
- MacCaption VANC File (.mcc)
- SMPTE Timed Text (.xml)
- EBU N19 Subtitle (.stl)
Note: The default option for NTSC regions is SMPTE Timed Text, and for PAL regions, it is EBU N19.
Depending on the format that you select, a list of supported frame rates are displayed in the Frame Rate pop-up menu. A default frame rate is chosen based on the known frame rate of the sequence that you are exporting.

Alternatively, you can also click Queue to send the sequence into the Adobe Media Encoder queue.
With QuickTime exports, you have the option of embedding captions in the video file or exporting them to a sidecar file. With all other export formats, you can export captions only as a separate sidecar file.

Closed Captioning workflow using third-party applications
If you are using any third-party captioning applications to create closed captions, here is a typical workflow you can follow:
Step 1: Export the sequence to a third-party captioning application
After you complete the video and audio editing in Premiere Pro, you export the sequence as a reference movie to a third-party Captioning application.
This movie can be sent to a Captioning service bureau or a Captioning specialist, where the movie is used as a reference to create a closed caption track from scratch. A third-party captioning application, like MacCaption from CPC, lets you create the closed caption track from scratch, and then encodes the closed captioning data in the necessary format.
Step 2: Import Closed Caption files into Premiere Pro
Once you receive the Closed Caption file from a third-party Captioning application, you can import the file into your project in Premiere Pro. Premiere Pro supports importing Closed Captioning files in .mcc, .scc, .xml, or .stl filename formats.
When you import a Closed Caption sidecar file into your project, a video-only clip is created containing the Closed Caption text blocks. You can make any further adjustments to the text blocks to keep it in sync with your media, as required.
A Closed Caption sidecar file contains multiple caption streams, for example, CC1, CC2. When such a clip containing multiple caption streams is added to a sequence, the Timeline shows separate track items for each stream. To switch among different caption streams, in the Captions tab, select a stream from the Caption Stream pop-up menu.
Step 3: Export the edited video
Once the closed captions are in sync with the media, you can export the edited video along with the Closed Caption file. You can export closed caption sidecar files and embedded QuickTime movies (QuickTime 608 captions) through Premiere Pro, as well as through Adobe Media Encoder.
Supported caption formats
- Premiere Pro supports reading and writing captions for MXF OP1a files. The captions are read from and written to the SMPTE 436M ancillary data track in the MXF OP1a file.
- Premiere Pro supports importing and exporting CEA-708 captions. CEA-708 closed caption files can be exported as a Sidecar file with a .mcc or .xml filename format. Or you can embed the CEA-708 captions within the SMPTE 436M ancillary data track in MXF OP1a files.
- Premiere Pro reads captions in QuickTime movies regardless of the video codec used.
- Premiere Pro lets you import caption files with a *.dfxp filename extension.
DFXP caption files are XML-based files. So besides viewing the captions in the Captions panel, they are also viewable from a text editor.
