What are automated subtitles?
Automated subtitles are the words displayed at the bottom of a video’s screen to show what’s being said. Automated subtitles are commonly referred to as closed captions in the television industry, and it’s a way to make videos more accessible.
How to add automated subtitles
Step 1: Record
Open the Tella app on your computer and log in or sign up within a couple of clicks. From there, pick the screen and webcam you want to record. You can create as many clips as you need. Once you’ve got the footage you want, you can move to the next step.
Step 2: Edit
You can trim together the recordings you made in the last step. With Tella, you can trim clips, rearrange recordings, go back and re-record if you need to.
Step 3: Share or Download
When you’re done, click “Finish.” You’ll go to a new window where you can watch your recording. To share it, you can export it, share it with a link, add a thumbnail, and change permissions. Your subtitles will be added automatically — viewers can toggle them on and off when playing the video.
How do automated captions work?
Video hosting platforms like YouTube have AI technology that generates closed captions for videos on their platform. The common name for this technology is ASR (Automated Speech Recognition). Tella’s app uses voice recognition technology to add subtitles to the recordings made on the app if creators choose to add them.
How long does it take to put subtitles on a video?
Most automated subtitles only take a few seconds to add to a video’s recording. What takes more time is the effort it takes to clean up the automated subtitles to make sure they’re 100% accurate. Automated subtitles usually get 70-80% of what’s said, but background noise or unclear audio can make it harder. That is where the creator has to go in and correct it themselves.
