Code:

InterpolateCameraPos(playerid, Float:FromX, Float:FromY, Float:FromZ, Float:ToX, Float:ToY, Float:ToZ, time, cut = CAMERA_CUT)

You need to use the params correctly.

If i is the playerid to be shown, then you should have (i, firstx, firsty, firstz, lastx, lasty, lastz, 5000)

That's why it's showing arguments not meeting definition, because it's expecting what is above, in that format, not what you are handing it.
