Tips for auto-generating subtitles

1. Break captions up evenly

Make your captions easier and quicker to read by breaking them up into even line lengths.

2. Look through the translation

Even if you don’t know the language in which you translate the captions, go through the video and check if the auto-translated subtitles correspond to the picture.

3. Ensure the readability

Make sure that the viewers have enough time to read and understand your subtitles. On average, subtitles should not exceed 170 wpm (words per minute) and, if possible, be kept to a maximum of 140 wpm.

4. Avoid obscuring important content

Choose the size and background for your subtitles that won’t let them obscure important elements in your video.
