TODO – How to shift clips around ∞

TODO – detailed instructions

You are limited by the size of the nearby clips.

Subtitle entries are red ∞

Entries are flagged red if Subtitle Edit thinks there is not enough time for the viewer to read your text. You can edit your preferences to set this time. Options > Settings > General and the various Rule entries on the left.

This is only a warning and you can ignore it.

Use less text, or break up your text into multiple subtitle entries.
