There are two very similar and easily confused advertising terms TVC and CF in TV advertising. The abbreviation of TV advertising is TVC (television commercial). It is mainly aimed at the media of advertising. Whether it is shot with film or tape, it is ultimately accepted by the majority of consumers through TV media.
CF (commercial film) is actually the English abbreviation of "film advertising". It is mainly aimed at the means of TV advertising production, because the film used for shooting movies has strong color tolerance and high sensitivity, which can better ensure the texture and level of the picture, and the light sensitivity is delicate.
So to be exact: TVC includes CF, and CF is the best way to make the overall picture of TVC. It is the same as the hotel logo design. Similarly, hotel logo design can also prevent TV advertising.
