Step-By-Step Guide
Before creating captions, open the Premiere Pro sequence you want to caption.
Make sure the sequence is active.
Make sure the sequence contains audio clips.
Make sure the spoken audio is on a track you can select.
If there is no active sequence, Caption X will not be able to load audio tracks.
In Premiere Pro, open the extension from Window, then Extensions, then Caption X.
Open Premiere Pro.
Go to Window.
Choose Extensions.
Click Caption X.
Once the panel opens, you'll see the login screen if you are not signed in yet.
Open Caption X from Window > Extensions.
Click Continue with Google.
This opens your browser.
You can sign in with Google.
You can create a new account with Google.
You can use email login if you prefer.
After signing in, return to Premiere Pro. The extension will update automatically.
The sign-in screen appears when you are not logged in yet.
At the top of the panel, choose the language spoken in your video. This helps Caption X transcribe your audio more accurately.
If your video is in English, leave it on English.
If it is in another language, choose the matching option from the language dropdown.
In the Select Audio Track section, choose the track that contains the spoken audio. If the dropdown is empty, click Refresh tracks.
Make sure the correct sequence is active.
Make sure the sequence contains audio clips.
Make sure the clips are actually on an audio track in the timeline.
Caption X only shows tracks that contain audio clips.
Select the spoken-audio track or click Refresh tracks if needed.
Under Select Caption Length, choose how you want the captions split.
Short Captions
Best for faster-paced, punchier captions with more frequent breaks.
Medium Captions
A balanced option for most videos.
Long Captions
Best when you want fewer, longer caption blocks.
If you are unsure, start with Medium Captions.
Caption length controls how the generated text gets split.
Under Caption Mode, choose one of these options.
Unstyled Captions
Creates plain captions you can style later in Premiere.
Styled Captions
Creates captions using the style settings in Caption X.
If you want captions to look ready right away, choose Styled Captions.
