Why it matters
max-video-preview sets the maximum number of seconds of a video preview in Search: 0 allows only a static image and -1 means no limit. Google said it does not expect -1 to produce an hour-long preview.
How to meet it
Add max-video-preview:-1 to the robots meta tag of watch pages unless licensing requires a limit.
How to test it
curl the watch page and check the robots meta content.
