Make a screensaver out of a tv-clock

[StarMike]

Hello! I'm completley new in this "business". I have two questions:

I wonder how to make a screensaver from a youtube-clip or a youtube-clip as a model? It's an old tv-clock from the danish TV-station DR 1 I'd like to have as screensaver. But I want the clock to be synced with my computer's clock.

My other questions is: Making a screensaver out of a testcard with webradio and synced clock.

I have nor or slight skills in programing.
I'd be nice to have it both for Mac and PC.
Is it possible to make screensavers like this?

Here are the examples.

I understand what you are trying to achieve, however, I am afraid this is not possible with screen saver development software. There is no way to synchronize video with your system clock. So if you would like to create something like that, you would have to do your own programming.
