What Is AI Video Generation?

AI video generation lets you create videos from text descriptions, images, or existing footage using deep learning models. Instead of hiring a crew, renting equipment, and spending days on set, you can produce professional-quality video content in minutes with nothing but a prompt.

Lumavo gives you access to 12+ state-of-the-art models — including ByteDance's Seedance 2.0, Kuaishou's Kling 3.0, and Alibaba's HappyHorse 1.0 — all through a single interface and API.

How AI Video Generation Works

Modern video generation models use diffusion transformers that have been trained on millions of video-text pairs. The process works like this:

  1. Text encoding: Your prompt is converted into a mathematical representation (embeddings) that the model can understand
  2. Noise initialization: The model starts with pure random noise in the shape of your target video
  3. Iterative denoising: Over many steps, the model progressively removes noise while conditioning on your prompt embeddings
  4. Temporal coherence: Special attention layers ensure motion is smooth and consistent across frames
  5. Decoding: The final latent representation is decoded into viewable video frames

Models like Seedance 2.0 perform this in under 40 seconds for a 5-second 720p clip on Pro hardware.

Choosing the Right Model

Seedance 2.0

ByteDance's flagship model excels at cinematic output with excellent prompt adherence. Two modes give you flexibility:

  • Pro mode: 720p at 40 credits/second. Best for final renders where quality matters.
  • Fast mode: 480p at 14 credits/second. Ideal for rapid iteration and drafts.

Kling 3.0

Kuaishou's model is the best choice for human-centric content. If your video features people dancing, playing sports, or showing natural movement, Kling 3.0 renders motion more convincingly. Priced at 17 credits/second for 720p.

HappyHorse 1.0

Alibaba's versatile model supports text-to-video, image-to-video, and video editing modes. Starting at 9 credits/second, it is the most cost-effective option for experimenting and prototyping.

Writing Your First Prompt

The difference between a mediocre and a stunning AI video often comes down to the quality of your prompt. Here is a framework we recommend:

The 5-Point Prompt Formula:
  1. Subject: What is the main focus? (a person, an object, a landscape)
  2. Action/Motion: What is happening? What moves?
  3. Setting: Where does it take place?
  4. Style: Cinematic, anime, photorealistic, 3D render, etc.
  5. Camera: Static, pan, dolly, drone, handheld?

[Subject] + [Action] + [Setting] + [Style] + [Camera Direction]


Example:


A lone astronaut planting a glowing flag on an alien planet with two moons


in the purple sky. Cinematic style with slow dolly-in camera movement.


Atmospheric fog rolls across the crystalline ground.

Prompting Tips

  • Be concrete, not abstract: "A golden retriever puppy running through a field of sunflowers at golden hour" performs dramatically better than "a happy dog outside"
  • Describe motion explicitly: The model needs to know what moves. "Leaves rustling in the wind" or "water rippling gently" guide the temporal behavior
  • Specify lighting: "Soft morning light", "harsh overhead sun", "neon reflections on wet pavement" — lighting defines mood
  • Use negative prompts for Seedance models: Tell the model what you do *not* want (e.g., "no blur, no static background, no text overlay")
  • Start short, iterate fast: Generate 5-second clips in Fast mode while you fine-tune your prompt, then switch to Pro for the final render

Your First Generation: Step-by-Step

Step 1: Create a Lumavo Account

Sign up at [lumavo.com](https://lumavo.com) to get 50 free credits. No payment required to start.

Step 2: Open the Studio

Navigate to the [Studio](/app) page. You will see the prompt input, model selector, and generation parameters.

Step 3: Choose Your Mode and Model

Select Video mode, then pick Seedance 2.0 Fast for your first test (only 20 credits). Fast mode delivers results in ~20 seconds so you can iterate quickly.

Step 4: Write Your Prompt

Try this starter prompt to see the model in action:

Wide cinematic shot of a misty forest at dawn. Sunlight breaks

through the canopy creating god rays. A small deer steps out


from behind a moss-covered tree. Camera slowly pans right.


Photorealistic style with soft morning lighting.

Step 5: Set Your Parameters

  • Aspect Ratio: 16:9 for YouTube/Vimeo, 9:16 for TikTok/Reels/Shorts, 1:1 for Instagram feed
  • Duration: 5 seconds is ideal for testing
  • Resolution: 480p for Fast mode tests, 720p for final output

Step 6: Generate and Review

Hit Generate and wait 20-45 seconds depending on queue. Your video will appear in the Recent Generations panel. Download it or iterate on the prompt.

Common Beginner Mistakes (and How to Avoid Them)

Mistake 1: Prompts That Are Too Vague

"A cool video" will give you random, often unusable output. The model fills gaps with its own (often unpredictable) priors.

Fix: Always write 2-4 sentences with subject, setting, action, and style.

Mistake 2: Skipping Fast Mode

Beginners often jump straight to Pro mode, burning 40 credits on a first attempt that has prompt issues.

Fix: Use Fast mode for your first 3-5 iterations. Once the prompt is dialed in, re-render in Pro.

Mistake 3: Ignoring Aspect Ratio

Generating 16:9 footage for a TikTok post means awkward cropping later.

Fix: Set the aspect ratio to match your target platform *before* generating. Re-cropping AI video often looks bad.

Mistake 4: Overlooking Resolution Needs

480p looks fine on a phone screen but blurry on desktop or TV.

Fix: Match resolution to your distribution channel. 480p for social previews, 720p for general use, 4K upscale for premium content.

Mistake 5: Not Using Reference Images

For image-to-video mode, many users skip the reference image — but this is the most reliable way to control composition and style.

Fix: Upload a mood board image, a rough sketch, or a style reference for more predictable output.

What Can You Create?

AI video generation is being used across industries:

  • Marketing: Social media ads, product demos, brand teasers
  • Content Creation: B-roll footage, YouTube intros, TikTok content
  • Education: Animated explainers, historical recreations, science visualizations
  • Gaming: Cinematic trailers, cutscenes, environment flythroughs
  • Film/Entertainment: Concept pitches, storyboards in motion, VFX previsualization

Integrating via the API

For developers, Lumavo provides a REST API that makes video generation a single HTTP request:

const response = await fetch("https://api.lumavo.com/v1/txt2video", {

  method: "POST",


  headers: {


    "Authorization": Bearer ${process.env.LUMAVO_API_KEY},


    "Content-Type": "application/json"


  },


  body: JSON.stringify({


    model: "seedance-20",


    prompt: "A serene mountain lake at sunrise with mist rising from the water. Camera slowly tilts up revealing snow-capped peaks.",


    duration: 5,


    resolution: "720p",


    aspectRatio: "16:9"


  })


});



const { taskId } = await response.json();


console.log(Task created: ${taskId});

Poll for completion:

curl -H "Authorization: Bearer $LUMAVO_API_KEY" \
