      Getting a good result

      Burned-in or separate captions

      Burned-in (open) captions are drawn into the picture. They show for everyone on every platform and cannot be switched off, which suits social video, where most people start watching with the sound off. A separate caption file can be switched on and off and read by a screen reader, which suits YouTube and course platforms. Many creators do both.

      Check the captions before burning them

      Once captions are in the picture, a typo needs a new export. Run the file through the readability checker for lines that are too long or too fast, and fix any wrong word in the caption editor first.

      Sizes follow the video

      Caption size is set relative to the height of the frame, so Medium looks the same on a 720p and a 4K video. For vertical video viewed on a phone, Large is usually right.

      Add subtitles to video: common questions

      Can viewers turn burned-in captions off?

      No. They are part of the picture. Keep your original video if you may want a version without them.

      My captions show strange characters. Why?

      The file was saved in an older text encoding. The tool reads such files as Windows-1252 and tells you; if accents are still wrong, open the file in the subtitle converter and save it again.

      Which languages can it draw?

      Latin alphabets with accents, Cyrillic and Devanagari. Other scripts are not supported yet.

      How long can the video be?

      Up to 5 minutes and 100 MB. Studio captions a whole recording of any length as part of the edit.
