The production of exhibition films is an offer from production agencies. In addition to the filming at the event itself, the service provider is also responsible for the cutting of image and sound, the editing of music, effects and comments and the final supply. Prior to the film production, the purpose and the target group of the film should be discussed in detail. These trade fair films can profitably affect a company's image and extend the benefits of the participation at the trade fair beyond the event itself. It is also possible to book a film production with an agency prior to the event. This film can then be shown at the exhibition stand as a means of information, for the acquisition of potential customers or as a means of drawing attention to the presentation of the company itself. As professional films are complex and costly, it is advisable to negotiate with multiple agencies before signing a contract.
