Help me upgrade my gaming laptop

[ApusDot]

I've been wanting to upgrade my almost absolute (if not already obsolete) gaming laptop. I would like to make it faster for video editing purposes, gaming is definitely secondary). I know that upgrading the graphics card is the obvious thing to do, but I can't figure out whether it's even possible, it may be soldered to the motherboard (can't figure out if it is). Am I better off buying a whole new PC/Laptop instead of upgrading the parts of this/my current laptop? I can't afford a whole newer system at the moment, but upgrading this one is something I can do with time. Thank you!
