Lesson 4 — Name the effect instead of describing the move

Module 2 · ~12 min

The most common way to waste credits is describing camera movement in prose. You write something that sounds cinematic, the model renders its reading of it, and you spend a generation finding out that "sweeping" meant something else to it than it did to you.

There's a shortcut, and it's the highest-return habit in the whole course: stop describing the move and name it.

How to do it

1. Before writing anything, decide what the camera does — orbit, rise, push in, freeze and rotate.
2. Open the effects library and find a preset that already does it. There are dozens with fixed names: BULLET TIME, EARTH ZOOM, TRACKING, STUDIO SLIDE, FLOATING FALL, INCLINE, HIGH FLIP, FROZEN IN MOTION.
3. Pick the preset. Use the prompt text only for what the preset doesn't control — who is in frame, where, in what light, wearing what.
4. Generate one take. If the move is right and the content is wrong, you fix the prompt. If the move is wrong, you change the preset. Never change both at once — you lose the ability to tell which one fixed it.

Why it works

A named preset isn't a hint, it's a fixed motion path. "Bullet time" has one meaning in the system and no meaning that needs guessing. Your prose version has as many meanings as the model has training examples.

It also fixes the thing that most gives AI video away as amateur: inconsistent movement between shots. If three clips in a sequence use the same named preset, they move identically. Three clips described in three slightly different sentences will move in three slightly different ways, and the cut between them will feel wrong without anyone being able to say why.

Where presets stop working

A preset is fixed, which is the entire advantage and also the limit. If what you need is a move nothing in the library does — a specific focal-length change, an unusual arc, a handheld feel with a particular rhythm — you're back to describing it, and back to spending takes to find it.

The working rule: use a preset whenever one fits, and only write prose for the move when nothing fits. Most people do the opposite — which is why most people's first ten generations are a loss.
