Google Drive supports caption tracks for stored videos, including uploaded caption files and account-dependent automatic generation. Captions need their own accuracy and timing checks. They also follow the video’s access controls, so do not treat a caption track as a separate private attachment.
Prepare a supported caption file
For a straightforward upload, use a supported format such as basic SubRip SRT in plain UTF-8. Check the timecodes, spoken text, speaker information where needed, and relevant sound descriptions. Google’s guide limits uploaded caption files to less than 2 MB.
Keep the source caption file and verify that its timing matches the actual video version. A transcript without appropriate timing is not automatically a complete synchronized caption track.
Add and review the track
On Drive’s web interface, right-click the video and open File information, then Manage caption tracks. Add a new track, select the file, choose its language and name, and upload it. Play representative sections with captions enabled and check the complete content where accuracy matters.
Automatic caption availability and generation can be controlled by Workspace administrators. When offered, review the generated words rather than assuming that proper names, numbers, or technical language are correct.
Check changes and sharing
Use the track management controls to update its name, language, availability, or replacement as appropriate. Google warns that captions apply to the video version they were uploaded to; replacing the video version can remove them. Recheck captions after any version update. People who can edit the video may also manage its captions, so verify the video’s audience and roles before adding sensitive caption text or translated material.
