Possible choices:
Showing films online via your own website or your own virtual platform has advantages: you remain in control of the presentation, branding and data collection. Parties that can help with this include Medialoc and Shift72.
By collaborating with an existing platform for virtual cinema, you can reach a larger and new audience that would otherwise not easily visit the physical cinema. Also, joining an existing platform can generate greater brand awareness and revenue, and avoid having to solve technical problems yourself.
Another possibility is to collaborate with a partner website for virtual cinema, for instance from a cultural institution, film festival or media platform. This is another way to increase your brand awareness and audience.
You can also use the technique of virtual cinema to facilitate offline film screenings, so that you can also show a virtual offering at a physical location. For example, Medialoc developed the Offline Stream Player for this purpose, a technique to show films at locations without a DCP projector or with an unstable internet connection.
