In VLC you can fix it like this:

- Press the J to advance them by 50 ms.
- Observe the dialogs and adjust until they match.
You can also do this in the menu:

A key detail is readability. If the subtitles are too small or use an awkward typography, you can customize them:
- Open Tools > Preferences > Subtitles/OSDs.
- Choose the source you prefer (Arial, Verdana, Times...).
- Change the font size.
- Select the color and style (bold, italic).
- You can even add a border or shadow for better readability on light backgrounds.
💡 This is ideal if you watch movies on a large screen or projector.
How to edit subtitles permanently 🛠️
If you want the changes to depend not on VLC but on the file itself, you will need to edit subtitles with an additional program such as Subtitle Edit o Aegisub.
Basic steps:

In this way, the subtitles will be ready for any player.
