Alternating fragments of scenes with events occurring simultaneously in different places, you can emphasize their relationship, compare or contrast characters and phenomena, make an analysis of events, that is, separate cause from effect, background from result.
Parallel mounting is also used to resolve difficulties when connecting frames. With this method, the total duration of scenes and episodes is significantly reduced, and the film as a whole becomes more dynamic, since it becomes possible to exclude routine and uninteresting actions of the characters without causing jumps in the development of the action.

Two or three storylines can be combined into one chain, since it is very difficult to track more parallel events. It is better to break the scene in the most dramatic place, then the viewer will expect the continuation with interest and attention.
And in order not to waste extra time on re-introduction to the course of events, a significant change in the situation in the storyline should occur on the screen, but not outside it, the environment of the continued scene should be easily guessed by the viewer. You can return at the moment of the break, but it is better to avoid even a short-term repetition (overlap) of the same action.
Multiple interruptions of the scene quickly get boring, let's remember the TV series! Something interesting or significant must necessarily happen in each separate fragment, otherwise the gap in the representation of some event will look far-fetched and superfluous. To emphasize the relationship of events, it is enough to switch to a parallel line just once. To indicate the equivalence of actions, fragments of alternating scenes are made approximately equal in duration and in the size of the plans.
"Simultaneous" outdoor events occur (must be presented on the screen) at the same time of day and time of year, with the same weather, etc. The impression of filming inside the building can spoil the landscape outside the window, contrary to other circumstances and the situation.
Simultaneity can additionally be emphasized by the influx of a parallel scene, and overlapping of sound tracks will be appropriate. When parallel events develop and echo for a long time, we should not forget that summer comes after spring, then autumn, winter, etc., as after morning comes day, evening and night.
