Dell Vostro V13 Graphics Card Upgrade?

Hey Everyone,

I'm wondering if anyone can help me. I have a Dell Vostro V13 Laptop and I considered upgrading the graphics card because I plan to use various video editing software. Specifically I'd like to use FXHome's HitFilm (minimum specs to run here).

The laptop has an integrated video card, the Mobile Intel(R) GMA 4500MHD and has 64MB dedicated video memory where as HitFilm and programs alike need a minimum of about 512MB dedicated video memory.

Is there any way, like at all, that I could possibly install a better graphics card, given the extremely compact size of my laptop?

Forgive me if this post seems naive, hardware has never been my strong point!

Thanks a lot,
Lewis
