I believe the binding proposal should state the measurement in the following format:
Horizontal video
Minimum height in pixels:
Minimum width in pixels:Vertical video
Minimum height in pixels:
Minimum width in pixels:
This way, the specifications are clear to both users and judges, with no room left for interpretation.
Additionally, it will be easy for the devs to code that as a requirement in the “Submit Profile” page once this is settled.
