Subtitles
Text synced with a video showing what’s said, in the same language or translated, in short blocks that appear and disappear.
Subtitles are the text of what’s said in a video, split into short blocks that appear on screen at the right moment. Unlike a transcript, they have to be readable while you watch the picture, so they follow rules on length and duration.
- At most 2 lines of about 42 characters.
- Each subtitle on screen for 1 to 7 seconds.
- A comfortable reading speed of about 17 characters per second.
- Breaks at pauses, sentence ends or changes of speaker, not in the middle of a phrase.
They can be delivered as a separate file, usually SRT or VTT, which the player shows or hides, or burned into the video picture.
Echo creates subtitles from the transcript following those rules, has an editor to fine-tune them, translates them into other languages and downloads them as SRT or VTT or burned into the video. More on the subtitles page and in the free subtitle generator.
