Is it Legal to Record Someone in Public and Film Prank Videos in India?

No. Filming in public places is generally allowed in India, but prank videos or public filming without consent can become illegal if they violate privacy, cause harassment, defamation, public nuisance, or involve deception and humiliation. 

Under Article 21, the right to privacy applies even in public spaces.

Laws like the IPC/BNS and IT Act can be triggered if content is offensive, misleading, obscene, or disruptive. 

Consent, non-interference, and ethical conduct are crucial, virality does not make content lawful.
