Bad starter? Cb750sc 1982

I'm holding the starter button and this is what is happening... See vid.
What the heck is that all about?
I tried to upload the video but it's too large. Working on it now. I've tried mp4 and mpeg but no success

Any link to the video?

The Pinterest video link is working, with audio.

You sure that battery is fully charged and has adequate voltage? That's always the first suspect.

What are all those yellow connectors on the left side of the video, and why do you have a pair of jumper cables hooked up to the bike?
