How to add subtitles and voice-over for social videos

There are plenty of reasons why the subtitle is needed for social videos. A lot of people use mobile phones to watch social videos in places where sound may be a hindrance. For example, many people watch social videos when they're commuting on busy public transport, cafes, and offices. As posts and videos are mixed together on social feeds, you don't want to annoy the audience by blasting sounds right away. Therefore, all videos are muted by default on Facebook and Instagram. Only on Tiktok - a video-only platform, the sound is turned on by default. Did you know that 75% of people admit to using their phones on the toilet? We bet you're doing too! According to Facebook, as many as 85% of people watch videos on its platform silently; therefore, you should make your videos optimized for soundless watching. Creating subtitles for social videos nowadays is the best practice.

Even for Tiktok, a video-only video platform with the sound turned on by default, many people on that platform still watch videos muted. TikTok is among the top 3 most popular social platforms for videos, having amassed over 138 million active users in the U.S. .
