Once your video is uploaded to your YouTube account, follow these steps:
Open the "Creator Studio" and select the video you wish to caption.
In the menu bar above your video, click "Subtitles/CC".
The "Set video language" will appear. This allows you to set the language that is
most spoken in the video. Click the drop-down arrow to select the language. Then click
To the right of the video, click the "Published - English (Automatic)" button. This
will generate a timed transcript of your video using YouTube's speech-recognition
software. It is not perfect and will need editing, but is a quick way to get the bulk of your spoken text transcripted.
You will then see your video with a time-stamped transcript to the left, and an audio
timeline below. The time-stamped transcript will be greyed out initially, so you'll
have to click "Edit" to make changes.
Once you've clicked "Edit", your time-stamped transcript should now be active. Press
play on the video, listen to the audio, and read the captions that appear on the screen.
If you need to make edits to the captions, simply click on the associated box in the
time-stamped transcript. If you need to adjust the syncing, you can drag the handles
on either side of each text box in the audio timeline.
Once you are finished editing your captions, click "Publish edits".
Your video is now ready to be posted. View the video below to see the above-described
process in action:
