Four minutes is a long time. This is why SciCast films are limited to 2:30: filling four minutes requires far more material than people expect. What they guess will take four minutes can invariably be done in 2:30, and if you think maybe 10,000 might see a film, that’s two hundred and fifty person hours right there that the world isn’t going to get back.

So keep it short.

In fact, four minutes is so long, you can cram an overview history of Saudi Arabia into it. Wow.

Mind you, it helps if you have seriously good graphic designers, mad skillz with 3D compositing, lots of time, and a vast archive budget.
