How to Generate a Video with AI

To generate a video with AI, choose an AI video platform (like PuppyDog, Synthesia, or HeyGen), write or paste a script, select an AI avatar or visual style, customize branding, and click generate. Most AI video generators can produce a professional-quality video in under 5 minutes without any filming, editing software, or video production experience.

AI video generation has gone from a novelty to a core business workflow. Marketing teams use it for product explainers, sales teams use it for personalized outreach, and customer success teams use it for onboarding and training content. Here’s how to get started—from choosing the right tool to generating your first video.

Step 1: Choose the Right Type of AI Video Generator

Not all AI video tools are the same. The right choice depends on what kind of video you need:

AI avatar video generators: These create videos with realistic AI presenters who deliver your script on camera. Best for training videos, explainers, and personalized outreach. Examples include Synthesia and its alternatives, HeyGen and its alternatives, and PuppyDog.

AI product demo generators: These turn screen recordings or screenshots into polished demo videos with AI narration and personalization. Best for B2B SaaS sales teams who need to create product demos with AI at scale. PuppyDog specializes in this category.

Text-to-video generators: These generate entirely new video footage from text prompts. Best for creative content, social media, and visual storytelling. Examples include Sora, Runway, and Kling.

Screen recording + AI editors: These enhance raw screen recordings with AI-powered editing, transitions, zooms, and cleanup. Best for tutorials and software walkthroughs. See our comparison of AI screen recording tools.

Step 2: Write Your Script (or Let AI Write It)

Every AI-generated video starts with a script. You have three options:

• Write it manually: Best for high-stakes content where messaging precision matters. Follow your company’s messaging framework and keep sentences short (AI voices handle shorter phrases more naturally)
• Use AI to generate it: Most AI video platforms include script generation. Provide a topic, key points, and desired tone—the AI produces a first draft you can edit
• Paste existing content: Repurpose blog posts, help docs, or email copy into video scripts. This is especially effective for turning SaaS explainer content into conversion-focused videos

Script best practices for AI video: aim for 130–150 words per minute of final video. Use conversational language, avoid jargon, and front-load the most important information. Break long scripts into scenes or chapters for better viewer retention.

Step 3: Select Your Visual Style

Depending on your tool, you’ll choose from:

• AI avatar/presenter: Select from stock avatars or create a custom avatar from a short recording of yourself. The avatar will lip-sync your script
• Screen recording with AI overlay: Record your product’s interface (or upload screenshots) and let the AI add narration, zoom effects, and transitions
• Fully generated visuals: For text-to-video tools, describe the scenes you want and the AI creates the footage from scratch
• Template-based: Many platforms offer pre-designed templates—just swap in your content, colors, and logo

Step 4: Customize and Brand

Before generating, add your brand elements:

• Upload your logo and set brand colors
• Choose a voice that matches your brand tone (professional, friendly, authoritative)
• Add intro/outro slides with your branding
• Set the aspect ratio for your distribution channel (16:9 for YouTube/website, 9:16 for social)
• Include a call-to-action (booking link, free trial URL, or next-step button)

Step 5: Generate, Review, and Iterate

Hit generate and wait for your video to render. Most tools produce output in 2–5 minutes for a 3-minute video. Then:

• Watch the full video: Check for pronunciation issues, awkward pauses, or visual glitches.
• • Edit specific scenes: Most platforms let you regenerate individual sections without redoing the entire video
  • A/B test versions: Try different avatars, voices, or script angles to see what performs best
  • Export in multiple formats: Download for your website, generate a GIF for email, or publish directly to hosting platforms

AI Video for B2B SaaS: The Biggest Use Cases

This approach delivers personalized demos that drive powerful results.

Sales prospecting videos: Sales reps generate personalized video messages for outreach—significantly increasing response rates compared to text-only emails. Learn how PuppyDog empowers sales success with AI-generated video at scale.

Customer onboarding and training: AI-generated videos help scale onboarding without overwhelming the CS team. Each customer gets tailored feature walkthroughs based on their plan, role, and usage stage.

Feature announcements: When shipping new features, AI video lets product marketing create professional announcement videos in minutes—no production team or studio time needed.

Tips for Getting Better Results from AI Video Generators

• Keep scripts under 3 minutes: Shorter videos perform better. Break long content into a series
• Use simple sentence structures: AI voices handle short, declarative sentences better than complex nested clauses
• Add visual variety: Mix avatar scenes with screen recordings, slides, or product shots to maintain engagement
• Test pronunciation: Industry jargon and brand names may need phonetic spelling in your script
• Include closed captions: Most viewers watch without sound. AI tools often auto-generate captions—always review them for accuracy

Copyright and Commercial Use

Before publishing AI-generated videos commercially, understand the licensing. Most B2B-focused AI video platforms grant commercial usage rights, but terms vary.
