While Lumiera will be able to handle various kinds of different content and data, the task of editing implies to arrange elements into a temporal dimension. Thus representation of time and expression of relations in time plays a pivotal role.
At first sight, time seems to we well-known, commonplace and trivial to understand — which however is a deception, since anything related to time, timings, duration and time scales is notoriously difficult to spell out with precision and tricky to handle in the practice of programming. A high-level discussion should thus
-
start with an analysis of usage situations
-
alignment to a pre-determined grid scale, the so called Time Quantisation requires careful attention
-
formal representation of Time Code is central to film editing.
