In this short blog post you will learn how you can use the latest advancements in speech recognition to add automatically generated subtitles to your video. We will show you three ways how you can use subtitles generated by a speech recognition software. Let's get started!

Do you know the difference between subtitles and closed captions?

Although people often use the terms subtitles and closed captions interchangeably, there are differences that set them apart. Subtitles represent a text alternative of the spoken language of the video. Often translated subtitles are used when the original audio is in a different language than the viewers mother language.

Closed captions not only provide the dialogue in written form, but also supplement information about background noises, soundtracks and other noises that are part of the scene. If you have Netflix and turn on subtitles, what you see is a good example of closed captions.

In essence, subtitles are targeted towards people who can hear the audio but also need the dialogue in written form. Closed captions on the other hand are targeted to an audience that cannot hear the audio and need a text description of sounds.

Why automated subtitles are the future

The rise of videos that are being uploaded on Youtube, Instagram and Facebook needs a scalable solution, that delivers quick and accurate subtitles. Current speech to text engines are getting better every day and in a few years will reach human-level understanding. AmberScript offers an online solution that combines the speed and scalability of automated speech-to-text engines and a human layer to bring it to 100% correctness. You just upload your audio or video, let the app do the grunt work of transcribing the audio to text, and then you or one of our human transcribers can perfect the text using our online editor.

Three ways to add captions and subtitles to a video

When you have checked and corrected potential mistakes that our robots made, you can export the subtitles in .srt or .vtt format, or directly upload the video with subtitles burned in the video itself. SRT stands for "SubRip Subtitle" and is one of the most common subtitle/caption file formats used. VTT ("Web Video Text Tracks Format") is a newer format that is becoming more popular in recent years, as it is compatible with online video players.

1) Using VLC player

If you have a video and the corresponding SRT subtitle file on your PC, and you just want to see the subtitles in action, do the following: play the video using VLC player and just drag and drop the .srt file onto the video to add the subtitle track.

2) Youtube

After uploading your video to Youtube you can attach subtitles to the video in the Video Manager. Click here for a more detailed description of how to do that.

3) Burn subtitles into video

If you want to have the subtitles directly burned into the video, you can just use AmberScript to export the video together with subtitles. In the export window within the editor, just select "Video with subtitles", let your video be generated and then download when it is ready.
