Editing down 140 days of recorded footage to 36 minutes of film was a challenge , but Hammer always wanted "Do Not Split" to be a short: "I like the power of short documentaries, and that's what Field of Vision specializes in. (...) I think more people tend to watch a short documentary, which is published in a way we try to make it accessible." [IndieWire, 2021]
To shoot "Do Not Split," Hammer used a still camera with video capabilities, the Canon X Mark II, which he calls "very robust." He used only a small microphone on top of the camera, and wore his zoom recorder across his body, which was protected from teargas in a small plastic case he designed: "I have a backpack, lots of batteries and memory cards. Then I have a quite small camera and just the sound system and everything is on my body so I can move and I can run and I can film all time." [IndieWire, 2021]
