You can optimize your current content to be able to reach more
audiences. YouTube provides several features to help you caption and
subtitle your videos for multiple languages and you can use metadata to
capture global searches.
Creating Captions
You can provide your own captions and transcripts, or YouTube has
several features to help you create and translate transcriptions of the
audio in your content. A transcript is a text version of the audio in your
video that you can upload to YouTube along with your video. This can
be used to create captions for the current language of the video, or
subtitles in other languages.
•
If you have a caption track for your videos already created, upload
them to YouTube.
•
If you upload a caption track on your video, YouTube can then
enable Auto-Translate, allowing it to be automatically translated for
users in 58 languages (variable accuracy).
•
To easily create captions for a video, write out the text of all the
audio and upload it. YouTube will auto-sync the timing to match
speech in the video. (English, Japanese, Korean speech only)
•
Use 3rd-party caption creation tools or ask fans to help create
captions.
Publishing & Optimization Reaching All Audiences
Metadata for a Global Audience
•
Adding captions to your videos will help it show up more places on
the site. If your video is captioned for multiple languages it will be
searchable in these languages.
•
When uploading content that is intended for multiple languages,
provide metadata and annotations for both languages, where
appropriate.
•
Using both English & other language metadata – Titles, Tags, and
Descriptions – helps discoverability through different search terms.
Download or edit the machine transcription created by
YouTube’s auto-caption as a starting point and edit for
accuracy. (More info about captioning your videos in
YouTube Support.)
