Legal analysis: If selling film and television cards is a legal and formal operation, it is generally not illegal. However, if the source of the video card is illegal, that is, it is not authorized by the merchant, it is illegal and is suspected of infringing the trademark and property rights of the merchant. If the perpetrator knowingly buys or sells a black card, it may also constitute the crime of covering up, concealing criminal proceeds, or criminal proceeds. Trademark rights refer to the exclusive and exclusive rights enjoyed by trademark owners over their trademarks. In China, since the acquisition of trademark rights follows the registration principle, trademark rights are actually exclusive rights applied by the trademark owner and confirmed by the State Trademark Office, that is, exclusive rights arising from trademark registration.

Legal basis: Article 213 of the Criminal Law of the People's Republic of China and the People's Republic of China, the crime of counterfeiting a registered trademark, uses the same kind of goods or services with the registered trademark without the permission of the owner of the registered trademark. If the circumstances are serious, they shall be sentenced to fixed-term imprisonment of not more than three years and concurrently or solely with a fine; if the circumstances are particularly serious, they shall be sentenced to fixed-term imprisonment of not less than three years and not more than ten years and concurrently to a fine.
