Where in the OP does it say it’s a 7 second video?
It’s right at the bottom right of the video itself.
I just see a white screen with the video arrow. No mention of time.
No idea why. I’m seeing the usual still image with a “play” arrow at the center, and down on the bottom right is the usual elapsed time and total time indicators: 0:00 / 0:07.
Please don’t start barelink OPs with vague titles in the future, I’m leaving this closed.
