Hiya, and welcome to BYC!

To upload a video, you can post it on YouTube, then share the link here.

It's probably the embryo moving. That looks like veins.

Let your broody sit on it for another 15-17 days.

That's a blood vein. Sometimes they move when the chick moves. All perfectly normal and signs of a healthy baby growing.
