Frequently Asked Questions
What are subtitles?
Subtitles are text originating from a dialog or commentary transcript or screenplay in movies, TV shows, video games, and the like, generally shown at the bottom of the screen, but may also be at the top of the screen if the text at the bottom of the screen is already present.
How can I generate subtitles for my videos?
By using HappyScribe's automatic subtitle generator you will be able to generate subtitles in 150+ languages. Just upload or add a link to your video and our subtitling software will extract the speech from your video file and convert it into subtitles with 85% accuracy.
Is the HappyScribe subtitle and caption generator free?
HappyScribe offers both free trials and paid plans. You can test the subtitle generator for free and upgrade for more features or longer videos.

How accurate are AI-generated subtitles?
The automatic subtitles are up to 85-95% accurate. For professional results, you can choose human-made subtitles with up to 99% accuracy.
Why should I use subtitles on my videos?

Is it safe to upload my videos to HappyScribe?
Yes, all video and audio files are securely stored and processed using industry-standard encryption and data privacy practices.
What is the difference between subtitles and captions?
Subtitles show the dialogue as text, often translated, for viewers who can hear the audio but may not understand the language. Captions also include sound cues and speaker changes, which makes them essential for viewers who are deaf or hard of hearing and for videos watched on mute. HappyScribe works as both a subtitle generator and an auto caption generator: upload your video, let the AI create the text, then export SRT or VTT files or burn the captions into your video.

By far the easiest service for transcriptions and subtitles I have found. I like that you can customize the font size and move the subtitles to the top or bottom of the video as needed.
