  • Subtitling has become one of the most important aspects of a video or an audio file. It reaches a wider audience, including those new to the language, those who have difficulty hearing, and those who, at the moment, cannot play the video with sound.

    A YouTube video containing subtitles tend to perform better than one does not, with 12% more view time. It boosts SEO, engagement, sharing rate, and search rank for content producers. Video and audio streaming platforms, apart from YouTube, also see the difference. 85% of all social media content is watched with the sound off. In such cases, captions and subtitles are almost the only determining factor of viewer retention.

    There is a minor difference between “Captions” and “Subtitles”. Captions are comprehension accessories for people who have difficulty hearing, while Subtitles are helpful for non-native speakers of the language. Captions describe the dialogues, background sounds (like a door opening or a gunshot), music, and speaker switching. On the other hand, subtitling merely converts the audible speech to visible text and excludes the invisible sounds.

    So how does one go about generating subtitles for audio and video?

    YouTube Videos

    To create captions for your YouTube video with timestamps, follow these steps:

    • Sign up or log in to your YouTube Studio account.
    • Select “Subtitles” from the expanded menu on your left.
    • Select which video you want to add the subtitles to.
    • Click on “Add language” and pick the language that you want the text to be in.
    • Under “Subtitles”, select “Add”.

    There are options for manually typing, auto-translating, automatic subtitle generating, and auto-syncing the text with the video. Transcript text is usually in sync with your video automatically if the language spoken in the video is the same as the text.

    You can add subtitles to an already uploaded video or even if you haven’t uploaded it yet. You can later download the YouTube video for circulation on other platforms.

    Non-YouTube Video and Audio content

    Platforms like Dailymotion, IGTV, Metacafe, and Vimeo also offer video and audio streaming services. To add subtitles to videos here, you can work with the following tools:
