Passing through the best of 2 video signals based on other input

Projects General Guidance
1

Just getting started with Arduino circuitry- here’s what I WANT to accomplish.... I’m not sure it can be done with an Arduino or not.

I will have four total signal inputs.
Two of these will be video signals.
Two of them will be in a range of 0-1V representing the strength of each one of their respective signals. The voltages are updated every 0.1S

I know the Arduino can differentiate the differences between 0-1V and make a “decision” which is better.... but what I want to know if the Arduino can then take ONE those 2 signals and pass it through to an output.

The main question is can can an Arduino passthrough a video signal out of one output?

Sorry if this is a stupid question but I’ve spent 20 hours trying to find the answer anywhere.

Thanks in advance for any help with this project.

No.
Get a video switch

Not by itself. You could use something like the NJM2233B 2-input signal video switch ($0.67 each at Mouser) and select the video using two GPIO pins..
