You might be better off with a dedicated video camera if video is your main objective.
If the OP has old Nikon AF lenses, they may not autofocus on the D5x00, or D3x00. Only AF-S compliant lenses that have their own focus motors will work on those bodies. Earlier, non AF-S lenses require a D90 or D7x00 or above to autofocus, as those bodies have their own focus motors, while Nikon's less expensive DSLRs do not.
