This article discusses common reasons why auto-generated captions would not generate for an uploaded video, and provides solutions to resolve the issues.
What is causing the Auto CC to fail?
These are the most common reasons Auto CC will not appear on videos, along with what to check for to fix the issue in the video file.
- Audio is missing or difficult to hear: Check if the audio is present and clear in your source video file.
-
Multiple audio channels in the video file: If there are large gaps in the transcript, be sure to check that the video doesn’t have multiple audio channels by using editing software such as Adobe Premiere.
- If so, try condensing the multiple audio channels into one and re-exporting the video.
- Language detection failed: Check if there is spoken word within the first 30 seconds in the desired language. The language detection uses the first 30 seconds of the video to determine the set language.
- Upload date: Ensure that the video was uploaded after May 2022; any videos that were uploaded before then will not have Auto CC generated. You can re-upload the video if you would like to generate Auto CC for it.
How to solve Auto CC failing
If you’ve identified one of the above as the cause of your Auto CC failing, adjust your video or settings as needed, then replace or re-upload your video to allow the captions to regenerate.
