Ai Video Creation

AI Video Creation

Overview

Video is the highest-effort, highest-impact marketing format. Traditionally, video required a camera, lighting, editing skills, and hours of post-production. AI flips this: you can now generate professional video from text alone. AI spokespersons deliver personalized demos. AI editors cut and caption in minutes. Generative AI creates B-roll from prompts. This skill covers every AI video workflow relevant to B2B GTM — from personalized outreach to social content at scale.

Step-by-Step Workflows

Workflow 1: AI Spokesperson Demo Video (1 hour)

Use case: Product demo, explainer video, "welcome" video for onboarding.

STEP 1 — Script (15 min, Claude):
"Write a 90-second product demo script for [product]. 
Audience: [ICP]. They care about [top 3 concerns].
Structure:
- 0:00-0:10: Hook — the problem they face
- 0:10-0:30: How [product] solves it (3 key features, outcomes-based)
- 0:30-0:60: Screen recording + walkthrough (you record this)
- 0:60-0:80: Social proof + results ('X teams use us, achieving Y')
- 0:80-0:90: CTA — 'Start free trial at [URL]'

Platform: spoken by AI avatar. Keep sentences short — under 15 words."

STEP 2 — Voiceover (5 min, ElevenLabs):
- Paste script into ElevenLabs Text-to-Speech
- Pick a natural voice (Adam, Bella, or similar — test 3+)
- Generate. Listen. Re-generate with pacing adjustments if needed.
- Download .mp3

STEP 3 — Avatar Video (10 min, HeyGen / Synthesia):
- Select AI avatar (matching your target audience's expectations)
- Upload script text
- Upload ElevenLabs voiceover (or use built-in TTS)
- Add: background (office, studio, or branded), on-screen text overlays
- Generate

STEP 4 — Screen Recording (15 min):
- Record product walkthrough (Loom, OBS, or QuickTime)
- Edit to match script timing

STEP 5 — Combine (15 min, Descript / CapCut):
- Layer 1: AI avatar video (talking head)
- Layer 2: Screen recording (when script references product)
- Layer 3: B-roll from Runway (generated visuals)
- Add: captions (auto-generated), background music (low, instrumental)
- Add: intro/outro branding
- Export: 1080p, 16:9

Workflow 2: Personalized Outreach Video at Scale (30 min per video)

Use case: "Hey [first name], I made this quick video for you..." Personalized videos get 3-5x higher reply rates than text-only outreach.

STEP 1 — Template Script (10 min, Claude):
"Write a 45-second personalized outreach video script. 
Personalization tokens: [first_name], [company], [pain_point].
Structure:
- 'Hey [first_name] — [relevant observation about their company/role]'
- 'The reason I'm reaching out: [pain_point is common in their industry]'
- 'We built [product] to solve exactly that. Here's what it does in 10 sec'
- 'I'd love 10 minutes to show you how it works. [Calendly] in comments'"

STEP 2 — Record Template Video (once):
- Record the template script with all personalization tokens clearly marked
- OR: Use HeyGen to generate an AI avatar video template

STEP 3 — Personalize (per prospect, 5 min):
- Research prospect: company, role, recent news, common connection
- Customize the observation: "I saw you just raised your Series A — congrats!"
- Record personalized intro (10 sec on Loom) or use HeyGen's personalization

STEP 4 — Edit & Send (5 min, Descript / Captions):
- Replace template intro with personalized intro
- Add prospect's name as on-screen text in opening frame
- Export. Upload. Send via email or LinkedIn DM.

Workflow 3: Social Short-Form Video at Scale (1 hour for 5 videos)

Use case: LinkedIn video, TikTok, YouTube Shorts, Instagram Reels.

STEP 1 — Batch Scripts (15 min, Claude):
"Write 5 short-form video scripts (60 seconds each) about [topics].
Structure:
- Hook (0-3 sec): bold claim, surprising stat, or provocative question
- Body (3-50 sec): one key insight explained with example
- CTA (50-60 sec): 'Follow for more [topic] insights'

Topics:
1. [topic]
2. [topic]
..."

STEP 2 — Batch Voiceover (10 min, ElevenLabs):
- All 5 scripts → ElevenLabs. Same voice.
- Generate as a batch.
- Download .mp3 files.

STEP 3 — Batch B-Roll (15 min, Runway):
- Generate 3-5 short clips per script (prompt: B-roll concept)
- OR: Use stock footage (Pexels, Pixabay — free)

STEP 4 — Batch Edit (20 min, Captions / Descript):
- Template: voiceover + B-roll + captions + branding
- Apply template to all 5 videos
- Auto-generate captions (Captions does this natively)
- Add: semi-transparent overlay at bottom with your handle
- Add: captions with word-by-word highlighting (95%+ watch time increase)

STEP 5 — Schedule:
- Upload all 5 to scheduling tool (Buffer, Hootsuite, native schedulers)
- Post 1/day for a workweek

Workflow 4: AI Video Ad Creative (2 hours for 5 variants)

STEP 1 — Strategy (15 min, Claude):
"Design a video ad strategy for [product] on [LinkedIn / Meta / TikTok].
Audience: [ICP]. Budget: $X. Goal: [demos / signups / leads].
Generate: 5 ad concepts with hooks, scripts, and visual direction."

STEP 2 — Scripts (15 min, Claude):
"Write 5 video ad scripts. Each: 15-30 seconds.
Variant 1: Problem/solution (hook: pain → product solves)
Variant 2: Social proof ('Join X teams...')
Variant 3: Demo teaser (show product, build curiosity)
Variant 4: Founder story ('I built this because...')
Variant 5: Objection buster ('Common belief: X. Reality: Y')"

STEP 3 — Production (60 min):
- HeyGen: Generate AI avatar delivering scripts 1, 2, 4
- Loom: Record screen for variant 3
- Runway: Generate B-roll for all variants

STEP 4 — Edit (30 min, Captions):
- Add captions (non-negotiable — 85% of social video watched on mute)
- Add branding (logo, colors, end card)
- Add background music (low, instrumental)

STEP 5 — Launch & Kill:
- Launch all 5. $50-100/day each.
- After 48 hours: kill bottom 3. Scale top 2.
- After 1 week: if CPA too high, iterate creative. Repeat.

Workflow 5: Podcast/Webinar Clips (30 min)

STEP 1 — Upload to Opus Clip or Descript:
- Upload your podcast episode (30-60 min)
- AI auto-identifies "viral moments" — high-energy, quotable segments

STEP 2 — Review & Select (5 min):
- Opus Clip suggests 5-10 clips. Pick the best 3-5.
- Each: 30-90 seconds

STEP 3 — Polish (15 min):

AI Video Quality Standards

What's production-ready:

• AI spokesperson videos with real voiceover (ElevenLabs or human)
• Screen recordings with AI narration
• Social clips from longer content
• AI-generated B-roll (abstract concepts, data visualization support)

What needs human touch:

• Customer testimonials (real people > AI avatars for trust)
• Complex product demos (AI can't anticipate all questions)
• Brand films (emotional storytelling needs real footage)
• Executive communications (your face > AI face for trust)

Implementation Checklist

• [ ] Script under 90 seconds (attention falls off a cliff after 90s)
• [ ] Hook in first 3 seconds (the most important 3 seconds of any video)
• [ ] Captions on every video (85% of social video watched without sound)
• [ ] Voiceover quality checked (natural pacing, correct pronunciation)
• [ ] AI avatar matches audience expectations (professional for enterprise, casual for SMB)
• [ ] Background music low enough to not compete with voice (-18dB to -24dB)
• [ ] End card with CTA (URL, follow, subscribe)
• [ ] File size optimized for platform (<100MB for email, <1GB for social)
• [ ] Thumbnail generated (Canva — face + text overlay)

Quality Check

Before delivering, verify:

• [ ] Output matches the user's stated request
• [ ] Named frameworks or sources are reflected in the recommendation
• [ ] The deliverable is specific enough for an agent to execute
• [ ] Any assumptions, risks, or dependencies are explicit
• [ ] No unsupported claims, invented facts, or private/internal references are included

Common Pitfalls

1. AI avatar uncanny valley. Poor lip-sync, dead eyes, robotic gestures =

viewers click away in 2 seconds. Fix: ElevenLabs voiceover with natural pacing. Test with 5 people: "Does this feel real?"

1. No captions. 85% of social video is watched without sound. No captions

= 85% of audience doesn't get the message. Fix: Captions on every video. Word-by-word highlighting increases watch time 95%+.

1. Script too long. 90 seconds is the ceiling for attention on social.

15-30 seconds for ads. 45-60 seconds for demos. Fix: Cut your script in half. Then cut it again. Every word must earn its place.

1. Generative B-roll that doesn't match. Runway generated "a team

collaborating in a modern office" shows 6-fingered people at impossible desks. Fix: Use stock footage or screen recordings for concrete scenes. Use Runway for abstract concepts, backgrounds, transitions.

1. Personalized video at scale that feels mass-produced. "Hey [first_name]"

with an AI avatar that clearly isn't you. Fix: Record the personalized intro yourself (10 sec on Loom). AI handles the rest. The human touch is worth the 10 seconds.

1. Ignoring platform specs. LinkedIn: 16:9 or 1:1, under 10 min. TikTok:

9:16 vertical, under 3 min. YouTube Shorts: 9:16, under 60 sec. Fix: Export in the correct aspect ratio and duration for each platform.
