AI Video Generation for Beginners: A Step-by-Step Guide
New to AI video generation? This beginner's guide covers everything from writing your first prompt to exporting cinematic clips using free tools like Lehar AI Studio.
AI video generation has gone mainstream in 2026. What once required a film crew, expensive software, and weeks of editing can now be accomplished with a text prompt and a browser. But if you’re new to the space, the terminology and options can feel overwhelming.
This guide walks you through your first AI video generation project — from concept to exported clip — using free tools available today.
What Is AI Video Generation?
AI video generation uses machine learning models to create video content from text descriptions (prompts), images, or other videos. You describe what you want to see — “a drone shot over a misty mountain at sunrise” — and the AI generates the video frames, often with surprising quality.
The best models in 2026 (Google Veo 3, OpenAI Sora, and those accessible through Lehar AI Studio) produce output that’s difficult to distinguish from real footage in many scenarios.
Step 1: Choose Your Tool
For beginners, we recommend starting with Lehar AI Studio for three reasons:
- It’s free — daily credits let you experiment without financial commitment.
- It’s browser-based — no software to install, no powerful computer required.
- It handles complexity for you — multi-model routing means the studio picks the best engine for your prompt automatically.

Step 2: Write Your First Prompt
A prompt is the text description of the video you want to generate. Good prompts share three elements:
Subject
What’s in the scene? Be specific.
- Weak: “a person walking”
- Strong: “a woman in a red jacket walking through a rain-soaked Tokyo street at night”
Action & Camera
What’s happening and how is the camera moving?
- Weak: “camera moves”
- Strong: “slow dolly forward following the subject, shallow depth of field”
Mood & Style
What should it feel like?
- Weak: “looks nice”
- Strong: “cinematic, warm color grading, film grain, anamorphic lens flare”
Putting It Together
Example prompt:
“A woman in a red jacket walks through a rain-soaked Tokyo street at night. Slow dolly forward following her, shallow depth of field. Cinematic warm color grading, neon reflections on wet pavement, film grain.”
Step 3: Generate Your First Clip
In Lehar AI Studio:
- Open the studio canvas.
- Type your prompt in the input area or ask the AI Copilot to help you refine it.
- Select your preferred output settings (resolution, duration).
- Click “Generate Draft.”
Generation typically takes 30–90 seconds depending on the model and output length.
Step 4: Review and Refine
Your first generation will rarely be perfect. Common refinements include:
- Camera motion too fast? Add “slower” or “subtle” to your camera description.
- Character looks wrong? Enable Character Lock after the first generation to maintain consistency.
- Lighting off? Add specific lighting terms: “golden hour,” “overcast diffused light,” “backlit silhouette.”
- Style too generic? Reference specific aesthetics: “Wes Anderson symmetrical framing,” “Blade Runner 2049 color palette.”
The AI Copilot in Lehar can suggest prompt refinements based on your description of what’s not working.
Step 5: Add Audio
Most AI video generators produce silent video. Lehar AI Studio is different — it can generate matching audio (ambient sounds, sound effects, even voiceover) on the same timeline.
To add audio:
- Select your video clip on the timeline.
- Use the audio generation panel to describe the soundscape (“rain, distant traffic, footsteps on wet pavement”).
- Generate and preview the audio match.
Step 6: Export
Once you’re satisfied with your clip:
- Click the export button in the studio toolbar.
- Select your format (MP4 for most uses, MOV for editing in professional software).
- Download to your device.
Your exported video is yours — no watermarks on Lehar’s free tier.
Tips for Better Results
Be Specific, Not Poetic
AI models respond better to concrete visual descriptions than abstract emotions.
- Instead of: “a feeling of loneliness”
- Write: “a single person sitting at an empty café table, wide shot emphasizing the empty space around them”
Use Reference Styles
Naming specific films, directors, or visual styles helps the model understand your intent.
- “Shot like a Christopher Nolan IMAX sequence”
- “Studio Ghibli watercolor animation style”
- “National Geographic documentary cinematography”
Iterate in Short Clips
Generate 3–5 second clips to test your prompt before committing to longer generations. This saves credits and lets you refine quickly.
Leverage the Copilot
Lehar’s AI Copilot can take a rough idea (“I need a product reveal video for a coffee brand”) and generate a polished prompt with camera directions, lighting, and mood — saving you the learning curve.
What to Create First
If you’re looking for project ideas to practice with:
- A 15-second product reveal for a fictional brand
- A nature documentary clip with voiceover narration
- A character walking through different environments (practice with character lock)
- A mood board video combining 3–4 short clips on a theme
Next Steps
Once you’re comfortable with basic generation, explore these intermediate features:
- Character Lock for consistent characters across scenes (read our guide)
- Camera motion presets for cinematic movements
- Multi-clip timelines for longer-form content
- Voice synthesis for AI-generated narration
The best way to improve at AI video generation is to generate a lot of video. Start with Lehar AI Studio’s free daily credits and experiment freely — every prompt teaches you something about how these models think.
