Frustrated with your AI video results? You're probably making one of these seven common mistakes. Here's how to identify and fix each one.

Mistake 1: Being Too Vague

The Problem

A nice video of nature

Why It Fails

The AI has infinite interpretations of "nice" and "nature." You'll get random, unfocused results.

The Fix

A misty forest at dawn with sunbeams filtering through tall pine trees, slow cinematic pan, peaceful and ethereal atmosphere


Mistake 2: Overloading Your Prompt

The Problem

A woman walking her dog while talking on the phone and it's raining and there's a rainbow and cars passing by and birds flying overhead and she's carrying an umbrella and groceries

Why It Fails

Too many elements compete for attention. The AI struggles to render everything well.

The Fix

Focus on 2-3 key elements maximum. "A woman walking her golden retriever on a rainy city street, colorful umbrella overhead, reflections on wet pavement, cinematic urban mood


Mistake 3: Requesting Readable Text

The Problem

A sign that says 'SALE 50% OFF' in clear letters

Why It Fails

Current AI video models struggle with consistent, readable text. Letters often appear distorted or change between frames.

The Fix

Avoid text entirely, or describe the concept: "A bright red sale banner waving in the wind, retail store atmosphere, promotional energy


Mistake 4: Ignoring Lighting

The Problem

A person sitting at a desk

Why It Fails

Without lighting direction, you get flat, uninteresting visuals.

The Fix

Always specify lighting: "A person sitting at a desk, warm lamp light casting soft shadows, cozy evening atmosphere, gentle rim lighting from a window


Mistake 5: Contradictory Instructions

The Problem

A fast-paced action scene that's calm and peaceful

Why It Fails

Conflicting directions confuse the AI, leading to incoherent results.

The Fix

Pick one mood and commit: "A high-energy action scene with dynamic camera movement, intense and thrilling, sharp motion blur


Mistake 6: Forgetting Motion

The Problem

A beautiful sunset over the ocean

Why It Fails

This describes a photo, not a video. You'll get minimal, awkward movement.

The Fix

Explicitly describe motion: "Golden sunset over a calm ocean, gentle waves lapping the shore, clouds slowly drifting, camera slowly pushing forward, peaceful golden hour atmosphere


Mistake 7: Not Specifying Style

The Problem

A cat playing with a toy

Why It Fails

Without style guidance, results vary wildly and rarely match your vision.

The Fix

Add aesthetic direction: "A fluffy white cat playfully batting at a feather toy, soft natural lighting, warm cozy home interior, gentle and heartwarming, lifestyle photography style
