All steps, in writing
Live captions
Open Media Captions and confirm Live captions. Select Caption display, translation & speakers to choose how the shared Captions region looks.
Expected: The destination region is configured before playback.
Captions from the Browser
For a video in SybilSight’s Browser, enable Captions from the Browser and turn captions on in the player.
Expected: The app reads the authored track from its own browser player.
Choose video
Choose a local video with an embedded caption track. Check available languages and play the video.
Expected: Cues appear on the phone and glasses as playback reaches their timestamps.
Choose file
For a screening or external player, load a subtitle file and start its clock when the media begins. Use −0.5s or +0.5s to correct synchronization.
Expected: The caption line matches the current media moment.
Search captions
Review history when you need to return to the text. For unrelated iPhone apps, use microphone captions; Mac media captions are handled in Terminal → Media.
Expected: You use a source the app can actually access.
If something differs
- iOS does not let this app read another app’s player captions or the system Live Captions overlay.
- Missing embedded tracks require a supplied subtitle file or microphone transcription.
- An incorrect offset makes authored text appear too early or late.
