Before You Bring Phone Subtitles to the Cinema: A Practical Checklist

Before you buy the ticket

1. Confirm the showtime’s dialogue language, dub and on-screen subtitle language. The cinema may already offer the right option.
2. Check the listed runtime and, when possible, the theatrical cut or regional version. A streaming or home-video subtitle may use a different timeline.
3. Check the venue’s phone and accessibility-device rules. Do not assume every cinema accepts a lit personal screen.

Before you leave for the cinema

1. Choose a subtitle file you are entitled to use. CinemaCC displays the file you choose; it does not grant rights to that file.
2. Open the file and check the first spoken lines against the same version when you can.
3. Prepare a second file if another release has a similar runtime. A backup is faster than searching after the lights dim.
4. Import the file into the installed iPhone app or Android beta before you need to go offline. For the Web player, load the page and import the file before you leave. Keep the tab open, and do not expect it to reopen or reload without internet.
5. Charge the phone and, if you plan to use it, the supported watch. Check whether battery-saver settings pause the app on your device, and change them only if needed.

Before the lights dim

1. Turn on Do Not Disturb and silence vibration if it could distract you or the people around you.
2. Set the display to the lowest brightness that remains readable to you.
3. Open the subtitle session, choose the correct primary and optional second track, and complete text-size or SDH settings now.
4. Place the device where you can glance at it without holding it up in another viewer’s line of sight. If that is not workable in your seat, do not force the setup.

When the film starts

1. Start the subtitle clock at the first frame or the start point you tested.
2. If the text is slightly early or late, use the ⏪ / ⏩ timing buttons instead of repeatedly restarting the session.
3. If the gap keeps growing, the file may match a different cut rather than having a simple one-time offset. Switch to the backup file when that is faster.
4. Do not photograph, film or record the movie. Personal subtitles are a text display, not permission to capture the screening.

How synchronization and microphone use work

If the setup is not working

• Stop adjusting for a moment and compare one clear line to determine whether the file is early, late or from a different cut.
• Switch files if the offset changes after scene transitions, logos, recaps or an intermission.
• Put the phone away if the screen cannot be used without distracting other viewers or if staff ask you to stop.
• After the screening, note the version and file that worked so the next visit starts with a known setup.
