Buttons over Video Using Text Buttons and 16:9
If you create subtitle buttons by typing text and using the text as the buttons on a 16:9
track, the highlights will work as expected when played on a 16:9 monitor.
How the track plays on a 4:3 monitor depends on whether you are using the letterbox
or pan-scan mode.
• If you play the 16:9 track on a 4:3 letterbox monitor: The highlights will not match the
text, because the highlight areas have been scaled along with the video.
• If you play the 16:9 track on a 4:3 pan-scan monitor: The highlights will match the text.

Creating Subtitles
Based on this behavior, it is recommended that text buttons not be used when creating
buttons over video on a 16:9 track that is set to play in the letterbox mode on a 4:3
monitor.
