5 Simple Ways to Add Captions to A Video for YouTube & Facebook

By Cecilia Hwung | Last Update:

Since not everyone can hear or turn on the audio while watching videos, captions become very important to improve comprehension. Lots of recent researches show that video with captions is more engaging and gains more social reach. For instance, Instapage found that captioned videos on Facebook had 16% higher reach than those without. If you have finished basic video editing and want more touch-up, consider captioning the video.

Note: Captions are different from subtitles even though sometimes people use them interchangeably. Subtitles are translated texts of dialogues and narratives for foreign audiences, while captions contain more elements like audio effects, relevant musical cues, etc. for people who cannot hear the audio.

Generally speaking, there are 3 ways to get captions for your video:

1. Auto-generate.

Google Doc Voice-typing, YouTube Automatic Subtitles, and Subtitle Horse are great audio to text extractors. Microsoft is also making strides in auto-transcribing. The audio transcription feature into Word for the web is newly-added for Microsoft 365 subscribers in Aug. 2020. But note that these tools generate plain transcript without time codes.

2. Write by yourself.

The second way is to type the texts line by line and sync the text to the audio. You can take a look at professional tools including Aegisubs, Jubler, VisualSubSync, and AHD Subtitles Maker. Meanwhile, online video platforms allow captioning videos in their studios like YouTube and Facebook.

3. Search and download from websites.

You can download closed captions for released movies and TV shows from subtitles sites that collect multilingual captions in SRT or ASS format. They are all embedded with synced timecodes so that you can save much energy to sync the captions to the video. But if you want to add captions to your own video, this is not workable.

To provide you the most comprehensive solution to captioning a video, we have made these 3 rough methods into detailed instructions with specific tools, including desktop software, online studios, and more. Check them now.

How to Add Captions to YouTube Video

The best part of YouTube studio is that it can do automatic captioning for free, which can free you from copy/pastes or typing workloads. It extract transcript from the audio and auto generate timing to help you easily extract text and added to video. Although the auto-created caption from audio may suffer from timing disorder and letter case issues, all you need to do is to fine-tune those minor problems in the corresponding boxes with video caption preview.

But if the video does not have the corresponding audio of the same language for the text, auto-sync feature won't be available.
