Twiceout is a startup based in Roma that designs and creates audiovisual content using the most sophisticated technologies. Since 2017 we have been making immersive audiovisual productions for virtual reality, both with 360 ° shooting and computer graphics. Our core business is the enhancement of the Italian artistic and cultural heritage through the production of immersive content, both for location based installations and for stand alone viewers using headset. In all our productions we use the latest generation ambisonic immersive audio. During 2020 Twiceout created an ambitious project called GrandtoVR, which allowed us to digitize some of the main Italian cultural sites: from the Colosseum to Pompeii, from the Royal Museums of Turin to the Valley of the Temples in Agrigento. This impressive operation allows the creation of online virtual guided tours, performed on our proprietary platform, using the virtual production workflow, via remote camera on Unreal Engine. Twiceout uses this cutting-edge technology to make independent productions such as documentaries and corporate products for companies.
