Subtitling for the Web

Web subtitles appear below the image for easier reading, unless you set the preferences for on-image subtitles.   The length of web subtitles is recommended to be longer than the usual short movie subtitles due to latency, slow loading, and digital "freeze".  

Creating subtitles that are full sentences will give people more time to receive the subtitles than traditional subtitles that are only a few words.   Because the subtitles appear below the image rather than on the image, this approach works well.   But if you prefer to create short subtitles, you are in control.
