How to Prompt AI Videos: 10 Tips for Better Results in 2026

Let's face it. Prompting AI-generated videos is 10x harder than prompting ChatGPT.

If you have ever used an AI video generator, you know how hard it is to get the exact video you want. What's worse, you often have to spend time waiting for your videos to finish just to iterate on your prompt.

It's not uncommon to spend hours just to create one video, not to mention all the credits you waste doing so.

Getting better at prompting can save you time, effort, and money. In this guide, we'll demystify the mystery of prompting by sharing our top 10 tips for AI videos.

These tips are drawn from the experience of creating 50,000+ AI-generated videos and posting the best ones on TikTok, Instagram, and YouTube, where they've received hundreds of millions of views.

Tip 1: Find Inspiration First

Like art, the easiest way to come up with video ideas is to steal, tastefully.

The great thing about prompting videos is that you can use both image and video prompts as inspiration.

The key is to find prompts that others have used, then customize them based on your vision.

One place to browse is Magic Hour's explore page, which has video templates with prompts that have been tested extensively. The Video-to-Video section has some of the most battle-tested prompts, including fictional characters, marble statues, and art styles.

For image prompt inspiration, browse creative communities like Pinterest, Behance, or Reddit's r/aivideo. Enter one word at a time in the search to see what types of variations people have created.

Once you find something you like, copy the prompt into your preferred AI video generator and try it out. You're already off to a great start.

Tip 2: Understand Prompt Structure

The way to think about video prompts is that they're like a bowl of soup.

The more ingredients you throw in, the less influence each ingredient will have.

Moreover, the ingredients you put in first — the words at the beginning — carry more weight than the words at the end. So when crafting a prompt, include the most important things first, then add supporting details like the background toward the end.

Note that there are diminishing returns. After a certain point, the words you're adding aren't likely to be impactful at all.

One important difference in 2026: Modern transformer-based models like Kling 3.0, Runway Gen-4.5, and Veo 3 understand natural language much better than the older diffusion-based models this article was originally written for. You can write more conversationally with these newer models. "A woman walks through a rainy Tokyo street at night, neon reflections on wet pavement, cinematic wide shot" works better than a keyword dump.

For Magic Hour's Video-to-Video and older style-transfer tools, the keyword-heavy approach still applies. For modern text-to-video models, lean toward descriptive sentences.

Tip 3: Be Specific

Prompts are not sentient. They cannot understand what you have in your head. There is no smart human on the other end deciphering your words.

You need to be specific. Include anything and everything you'd like to see, unless you want the AI to fill in the rest by chance — which is also okay depending on your goal.

Below are categories of words to include for a rich, complex video:

• Subject: Person, animal, character, location, or object
• Action: What is the subject doing? Walking, jumping, turning, speaking?
• Medium: Photo-realistic, painting, sculpture, animation
• Artist or style reference: In the style of Studio Ghibli, Van Gogh, cyberpunk, film noir
• Environment: Indoors, outdoors, another planet, a fictional realm
• Lighting: Cinematic, golden hour, neon, fog, God rays, bokeh
• Color: Dim, colorful, vibrant, muted, flat
• Composition: Wide shot, close-up, aerial view, over-the-shoulder, Dutch angle
• Camera movement: Slow dolly in, tracking shot, handheld, static

Camera movement is a newer category worth calling out specifically. Models like Kling and Runway respond well to explicit camera instructions. "Slow dolly in toward the subject" or "camera orbits left around the character" produce distinctly different and often better results than leaving camera movement unspecified.

Tip 4: Use Quality Modifiers — But Know Which Models They Help

If you've ever seen prompts for images and videos, you might have seen words like:

masterpiece, best quality, extremely detailed 8k wallpaper, ultra-detailed, high contrast, trending on artstation, award-winning, professional

Do these words matter in 2026? It depends heavily on which tool you're using.

For diffusion-based tools and Magic Hour's Video-to-Video mode, these modifiers still have a real effect. They work because they were used to tag high-quality images in training data from sites like ArtStation and DeviantArt. Including them nudges output toward those images.

For modern transformer-based models like Kling 3.0, Runway Gen-4.5, and Veo 3, these modifiers have a much weaker effect. These models understand meaning rather than keyword patterns. On these tools, descriptive quality language works better: "photorealistic," "cinematic lighting," "film grain," "shallow depth of field" are more effective than "masterpiece" or "trending on artstation."

On Magic Hour, art style templates come pre-loaded with quality modifiers relevant to each style, so you do not need to worry about this for those workflows.

Tip 5: Add Visual Flair

There are certain words that add an extra bit of touch that really brings a video to life:

energy swirls, aura, glowing runes, motion lines, motion blur, particles, light trail, glowing eyes, lens flare, god rays, volumetric fog, chromatic aberration, depth of field

These give videos a lifelike, post-production quality that makes them visually engaging. For example, modifiers like "energy swirls" and "aura" produce dramatic effects in action and fantasy content.

When choosing flair modifiers, try them all and see which ones suit your style. Different modifiers work better for different aesthetics. Sometimes stuffing a few into the same prompt produces surprisingly good results — the interaction between modifiers is part of the experimentation.

For 2026 models specifically, lighting flair terms like "volumetric fog," "god rays," and "lens flare" tend to have the strongest effect. Motion terms like "motion blur" and "light trail" work well for action sequences.

Tip 6: Specify Face Directions

AI models still struggle with faces that are not fully front-facing. If your video or source footage includes people facing away from the camera, AI models will sometimes render a face on the back of someone's head.

The best workaround is to include "from behind, facing away from viewer" in your prompt if a substantial portion of your video includes people facing away.

Even if only part of your video involves this, it is worth including the modifier. The opposite problem — AI rendering the back of someone's head on their face — is much less common.

For 2026 models, you can also specify the camera angle more explicitly: "subject's back to camera," "rear view," or "watching from behind" all signal to the model what you want.

Tip 7: Test Before Committing Credits

Before running a full-length render or burning credits on a long clip, test your prompt first.

For Magic Hour's Video-to-Video mode: You can watch the video render frame-by-frame in real time in Animation and Video-to-Video modes. Use this to catch problems early rather than waiting for the full render.

For text-to-video models (Kling, Runway, Veo 3): Generate a short 3 to 5 second version of your clip before committing to a longer generation. Most platforms charge by the second, so a short test at 540p costs a fraction of a full-quality 10-second render.

For style testing: Enter your prompt into a fast image generator first. The results will not be identical to your video output, but they give you a rough sense of composition, lighting, and color direction before you spend video credits. This is especially useful for Magic Hour's Video-to-Video workflows.

Tip within the tip: Keep the camera mostly static during test prompts. Camera movement adds complexity that can obscure whether the core subject and style are working as intended.

Tip 8: Store Your Favorite Prompts

Keep a running document with all your favorite prompts, prompts you are testing, and new ideas. Iterate on it regularly and remix past prompts that worked well.

This builds your own "taste library" over time — a repository you can draw on rather than starting from scratch every session.

A simple structure that works well:

• Working prompts: Ones that produced results you liked, with a note on what they were used for
• Testing queue: New ideas and variations you want to try
• Style notes: Which modifiers work well together for your preferred aesthetic

On Magic Hour, many tested prompts are already available as templates in the Video-to-Video section. These are a good starting point if you are building your own library.

Tip 9: Match Your Prompt to the Right Tool

Each prompt performs differently depending on which model you use. A prompt that produces excellent results in Runway may look flat in Pika, and vice versa. The reason is that each model has different training data, architecture, and aesthetic tendencies.

In 2026, here is a rough guide to matching prompt style to the right model:

• Kling 3.0: Responds well to narrative scene descriptions with explicit camera instructions. Strong on photorealistic human characters and multi-shot sequences. Use it for: cinematic B-roll, character-driven content, anything requiring realistic human motion.
• Runway Gen-4.5: Responds well to structured prompts with reference images. Strong on character consistency across shots and controlled camera movement. Use it for: branded content, multi-shot narratives, any content where the same character needs to appear consistent across multiple clips.
• Veo 3 / Google Flow: Responds well to descriptive, natural language prompts with environment and atmosphere detail. Strong on realistic outdoor scenes, physics, and native audio generation. Use it for: cinematic scenes, content requiring synchronized audio and dialogue.
• Pika 2.5: Responds well to stylized, effect-driven prompts. Strong on creative transformations and social-ready content. Use it for: TikTok and Reels content, stylized effects, fast iteration.
• Magic Hour Text-to-Video and Video-to-Video: Responds well to style-reference prompts with quality modifiers and art direction terms. Strong on stylized aesthetics across anime, cinematic, realistic, and artistic styles. Use it for: social content, creative transformations, and style-driven output from existing footage.

One approach that works well is entering the same prompt on two or three models side-by-side to benchmark which produces the best result for that specific type of content. Most models have free tiers that make this comparison affordable.

Tip 10: Share Your Work and Learn From the Feedback

Share your videos on social media. The main reason is to see what types of content viewers actually respond to, which tells you which prompts worked.

Then create more content using similar prompts and craft variations from what performed well.

For example, through posting consistently it becomes clear that viewers love marble statues and superhero content in Video-to-Video content. Without regular posting, you would never learn which aesthetic directions resonate.

On Magic Hour, you can also submit your videos as templates. Each submission is reviewed manually, and if accepted you earn 100 free credits every time the template is used by another creator.

Bonus: Common Prompting Mistakes and How to Fix Them

Mistake: Prompt is too vague "A person walking" produces inconsistent, generic results. "A woman in her 30s in a dark trench coat walks through a rain-soaked Tokyo alley at night, neon reflections on wet pavement, slow tracking shot from behind" produces something specific and compelling.

Mistake: Conflicting instructions "Bright, sunny outdoor scene with dramatic dark shadows and moody fog" sends contradictory signals. The model will interpret one or average between them. Pick a consistent visual direction.

Mistake: Using Stable Diffusion quality modifiers on transformer models "Masterpiece, trending on artstation, 8k ultra-detailed" has little to no effect on Kling, Runway, or Veo. On these models, replace with descriptive language: "photorealistic," "shallow depth of field," "natural film grain."

Mistake: No camera or motion direction Leaving camera movement unspecified means the model decides. Sometimes that is fine. When you have a specific shot in mind, say it explicitly: "static camera," "slow push in," "handheld," "orbital camera moving right."

Mistake: Too many competing subjects "A dragon, a knight, a wizard, and a castle in a storm" splits the model's attention across four subjects. One or two focal elements produce stronger, more coherent results. If you need multiple elements, establish hierarchy in the prompt: start with the primary subject and treat others as supporting details.

FAQs

Why does my AI video look nothing like my prompt? The most common causes are: vague subject description, conflicting visual instructions, or using prompting conventions from one model on a different model. Be specific about subject, action, environment, lighting, and camera angle. Test with a short clip before committing to a full render.

Do quality modifiers like "masterpiece" still work in 2026? For diffusion-based tools and Magic Hour's Video-to-Video mode, yes. For transformer-based models like Kling, Runway Gen-4.5, and Veo 3, these keywords have little effect. Use descriptive language instead: "photorealistic," "cinematic lighting," "natural film grain."

How long should an AI video prompt be? For most models, 50 to 150 words covers the sweet spot. Shorter prompts leave too much to chance. Longer prompts dilute the influence of individual words. Front-load the most important elements: subject, action, visual style, lighting. Add environment and camera direction toward the end.

Can I use the same prompt across different AI video tools? You can, and it is a useful benchmarking exercise. But expect significantly different results. Each model has distinct aesthetic tendencies, strengths, and weaknesses. A prompt optimized for Runway's character consistency may need adjustment to get the best out of Kling's scene generation.

How do I get consistent characters across multiple clips? Use a reference image whenever the model supports it. Runway Gen-4.5's reference image system is currently the strongest for character consistency across separate clips. Kling 3.0's multi-image reference input also helps. Describe specific, unique character details in the prompt text — hair color, clothing, distinguishing features — to reinforce the visual identity beyond what the reference image alone provides.

What is the fastest way to improve my prompting? Generate the same scene on three different prompts and compare the results side-by-side. The differences reveal which elements your prompt is actually controlling versus which elements the model is interpreting freely. Adjust the elements where the model diverged from your intent and re-generate. This feedback loop produces more learning per credit spent than any other method.
