Which videos are eligible for automatic closed captions (Auto CC)?

Automatic captions are only generated for videos that are 8 hours or less in length. They will also only apply to videos uploaded after May 2022. 

Why would Auto CC fail for my video?

Auto CC for your video may fail for several reasons: 

• If it contains silence for the first 30 seconds, the software won't detect any speech to transcribe.
• If it contains music or background noise louder than the speaker, stereo audio that is out of phase, and/or poor audio quality.
• If the language spoken in the video isn’t supported by Auto CC. 

If your video does not have any of these reasons, and you continue to experience issues with Auto CC, please contact Support.

What languages are available for automatic closed captions?

Automatic closed captions are available in English, French, German, Portuguese, and Spanish.

English is available to all users. French, German, Japanese, Korean, Portuguese, and Spanish are available only to Pro/Standard membership and above. 

If your account is set to one of these preferred languages, your videos will be eligible for automatic captioning.

If you would like to offer additional languages to your audience, you’ll need to upload separate subtitle or caption files. 

⚠️Note: Automatically generated captions are labeled as "Autogenerated” to clarify to viewers and distinguish between manually uploaded captions.

Why don't my older videos have Auto CC?

ZenVideo offers automatic closed captioning to all paid members for videos uploaded after May 25, 2022. This means that all videos will be automatically transcribed by our system during the upload process. If your video was uploaded before May 25, 2022, re-uploading your video will generate automatic closed captions.
