How to write prompts that actually render well

Wulo AI's ad and story concepts already write a detailed master prompt for you — but if you're editing that prompt, or writing one from scratch, these are the patterns that make the biggest difference in what comes back.

1. Name the shot, not just the subject

A text-to-video model has no idea what "cinematic" means on its own — it's inferring tone from concrete details. The fastest upgrade to any prompt is naming a camera angle and a lens the way a cinematographer would: wide shot, close-up, dolly-in, handheld, aerial. "A car driving" is a guess. "A low-angle tracking shot of a car driving through rain-soaked streets at night" is a shot list.

2. Lighting and time of day carry more weight than adjectives

"Beautiful" and "stunning" do almost nothing — the model has no fixed idea of what those mean. Lighting direction and quality do a lot more: golden hour, hard overhead light, soft window light, neon reflections on wet pavement. Pair lighting with a specific time of day (dawn, twilight, midday) and the result reads as considered rather than generic.

3. Describe motion, not just a static scene

These are video models — a prompt that only describes a still image leaves the motion entirely up to guesswork. Say what moves and how: slow rotating reveal, waves crashing, camera pushing in, steam drifting upward. If nothing in the prompt moves, expect a mostly static shot with incidental camera drift.

4. Keep one subject, one consistent look

If a product or character needs to look the same across a longer, multi-segment render (anything using "Continue this clip"), describe it once, precisely, and reuse that exact description rather than re-describing it slightly differently each time — small wording drift between segments is where inconsistency creeps in.

5. Say what you don't want

A negative prompt (Wulo AI's ad and story concepts generate one automatically) heads off the most common failure modes: warped hands, flickering, text artifacts, a logo that subtly changes shape. It's the cheapest fix available and it's easy to forget when writing a prompt by hand.
