Is that some misspelling of Sunrises? How'd you manage to do it on the video too?
Sunrives comes from "Sun Arrives" to replace Sunrise
I made the video from 10th floor of an apartment using a camera of cheap cellphone. It's likely, only such cellphone can capture the view of "black dot sun".
Ah okay.
Still see your using that debunked video out of your prideful ignorance.
The video claims the sun gets cut off from view before it can change apparent size.
One. The sun on a flat earth wouldn’t be blocked from view. The only way the horizon can block the sun from view, block its light, and block the sun so it can’t be brought back into view with the zoom of a telescope if the sun goes relatively below the horizon. This indicates a rotating spherical earth where the curvature of the earth blocks the sun from view.
Two. The sun on a flat earth would change apparent size throughout the day.
Three.
As the sun traveled overhead on a flat earth, it would look like this.

It would appear to slowly come out of the east. Appear to pickup apparent speed and size. Zoom overhead. Then appear to slow down and shrink as it passes westward.
This is reality where the sun stays the same speed and size as it arch through the sky. Not travel straight on.

Four. The sun would have to turn relative north and travel roughly along the west coast after passing over flat earth California.
