Using The Same Video in Different Resolutions as Splashscreen

Hey Guys!
Someone can help me?
i worked hard on sony vegas creating a splashscreen for my studio, and i know i can use a video as splashscreen with scripting, but i have a idea and i don't know if this is possible, but:

can i render a lot of versions of the same video in different resolutions, and create a script for the game detect the player screen resolution and use the appropiated splashscreen resolution

EXTRA:
"you can create a splashscreen in unity editor"
Yep i know, but the problem is: i used some effects that are VERY hard to simulate with splashscreen scripting for Unity, and i worked hard on that splashscreen

 

Detect the current resolution:

As far as different resolutions of the same video, I'd assume you'd just make them different videos and play whichever one you want.

 

Who says that your very first scene cannot be a "splash screen"? (Or second if the very first one is just an initialization empty scene like for me...)

 

Thanks Dude!
