As more and more moving images are consumed on mobile devices, often in upright format, i.e. without turning the mobile phone, the German Football League is pragmatically considering offering a special game transmission for these smartphone viewers -- and instead is tilting some cameras: Recently the Bundesliga game between VfL Wolfsburg and SV Werder Bremen was produced as a test balloon in 9:16 format (UHD) in addition to the usual broadcast format (but only for internal evaluation).
For this, however, the usual broadcast recordings were not simply cropped, but for maximum resolution five cameras were used, which were tilted 90° to the side. The direction´s monitors were also installed on edge. The production in standing image format requires a complete rethink by all participants, because logically there is not much space in the picture at the side, while new areas open up at the top and bottom. One of the things that was at stake in this trial run was to find out where the cameras could be optimally positioned; filming the action as usual from the sideline, with running movements from left to right, would probably be less appropriate than the perspective from the goal lines. Interesting is also the remark of a cameraman, now everything has to be kept nicely in the middle (unlike otherwise), so that nothing slips accidentally out of the framing.
The DFL is satisfied after his experiment -- when a first official transmission will take place, however, it is open whether actually whole games should be streamed in 9:16, or only summaries.
