Ai Video Generator Tutorial: Complete Guide for 2026

This tutorial walks through creating videos with AI tools, from text-to-video generators to AI avatar platforms to AI-assisted editing. Each section covers specific steps you can follow to create professional-looking videos without traditional filming.

Tutorial 1: Creating Video from Text Prompts

Text-to-video tools like Runway, Pika, and Kling generate footage from written descriptions.

Step 1: Choose Your Platform

Sign up for one of these tools:

• Runway Gen-3: Best for realistic motion, costs credits per generation
• Pika Labs: Free tier available, good for stylized content
• Kling: Strong at human movement and facial expressions

Step 2: Write Your Prompt

Be specific about what you want to see. Include:

• Subject (person, object, scene)
• Action (walking, spinning, floating)
• Setting (office, forest, abstract background)
• Camera movement (slow zoom, tracking shot, static)
• Style (cinematic, animated, documentary)
• Lighting (golden hour, studio lighting, moody)

Example prompt: "A coffee cup on a wooden desk, steam rising slowly, morning sunlight streaming through window blinds, shallow depth of field, slow motion, warm tones"

Step 3: Generate and Iterate

Generate 3-5 versions. Review each and note what worked. Adjust your prompt based on results. Keep the elements that succeeded and refine the rest.

Step 4: Download and Edit

Export your best clips. Use traditional editing software to trim, combine multiple generations, and add to your larger project.

Tutorial 2: Creating AI Avatar Videos

AI avatar tools create videos of virtual presenters speaking your script. Useful for training videos, product explainers, and content in multiple languages.

Step 1: Choose Your Platform

• Synthesia: Professional-looking avatars, good for corporate content
• HeyGen: Strong lip-sync, custom avatar options
• Colossyan: Designed for learning and development content

Step 2: Write a Conversational Script

AI avatars work best with natural spoken language:

• Keep sentences under 20 words
• Avoid complex jargon
• Write how people actually talk, not formal prose
• Include natural pauses (use periods for breathing room)
• Read your script aloud before submitting

Step 3: Select Avatar and Voice

Browse the avatar library. Match presenter style to your audience and content type. Test 2-3 voices with a short script segment to find natural delivery.

Step 4: Add Visual Elements

Upload slides, images, or screen recordings to appear behind or beside the presenter. Plan transitions between speaker and supporting visuals.

Step 5: Generate and Review

Generate the full video. Watch carefully for:

• Pronunciation errors (add phonetic spelling if needed)
• Unnatural pauses or pacing
• Lip-sync quality
• Awkward gestures

Most platforms allow regenerating specific sections without redoing the entire video.

Tutorial 3: AI-Assisted Video Editing

AI editing tools speed up common tasks on existing footage.

Automatic Transcription and Captions

1. Upload video to Descript, Kapwing, or CapCut
2. Wait for automatic transcription (1-5 minutes)
3. Review and correct errors
4. Edit the transcript to edit your video (delete text to delete footage)
5. Style captions with fonts and colors
6. Export with burned-in captions

Removing Filler Words

1. Upload video with spoken content to Descript
2. Enable "Filler Word Detection"
3. Review suggested cuts (ums, ahs, like, you know)
4. Approve or adjust each removal
5. Export cleaned version

Creating Social Clips from Long Videos

1. Upload long-form video to Opus Clip or similar tool
2. AI analyzes and suggests highlight moments
3. Review suggested clips
4. Select best options for your platform
5. Reformat to vertical if needed
6. Add captions and export

Best Practices Across All AI Video Tools

• Always review output: AI makes mistakes. Never publish without human review.
• Iterate on prompts: First attempts rarely perfect. Treat it as a conversation.
• Combine AI with real footage: Use AI for b-roll and supplementary content, real footage for authenticity.
• Keep expectations realistic: AI video is improving rapidly but still has limitations.
• Document what works: Save successful prompts and settings for future reference.
