What you actually get for $5 of AI video
Late 2024 → early 2026 was the inflection. Sora 2, Veo 3, Runway Gen-4, Kling 2.0, and Luma Ray 2 all cleared the 'good enough for ad use' bar. A $5 generation is now reliably 8–10 seconds of 1080p, coherent motion, intelligible faces (in close-up), basic physics, and — with Veo 3 — synced ambient audio. Where it still fails: hands, text overlays, multi-character continuity, long takes (>15s), and tight brand consistency across scenes.
Why your reject rate decides the budget
Reject rates on AI video are higher than image work — typically 60–80%, vs 50–70% for images. Drivers: motion artifacts (faces morphing, limbs duplicating), failure to honor prompt details (wrong product color, wrong setting), and physics breaks. A campaign that needs 30 final clips at a 75% reject rate is really 120 clip generations — $480 at $0.50/sec/10s, not $120. Reference-image conditioning (Runway, Sora) and longer-prompt control (Veo 3) typically cut reject rate 15–25 points.
When AI video doesn't make sense yet
Skip AI video for: regulated industries (pharma, financial services with disclaimer requirements), brand-character continuity over a full campaign, anything needing legible UI screen recordings, and anything where on-screen people are recognizable named talent. Hybrid workflows — AI for B-roll and transitions, real footage for hero shots — currently get the best of both at 30–40% lower budget than full traditional production.
Pricing the AI vs. real-shoot decision
Use this rule of thumb: if your traditional per-clip budget is under $400 (TikTok content, internal training, social proof), AI usually wins on cost AND speed. If it's $400–$2,000 (paid social, mid-tier ads), AI wins only if creative latitude is high. Above $2,000 (TV spots, brand films, hero campaigns), AI is currently a complement, not a replacement.

FAQ
Is Sora the cheapest AI video model?
No — Kling 2.0 standard tier is roughly 40% cheaper per second. Sora 2's premium is for prompt fidelity, length stability up to 20 seconds, and better human motion. Test 5 clips on the same prompt before committing to a provider.
How long does a 10-second generation take?
Sora 2: 30–90 seconds. Veo 3: 60–180 seconds. Runway Gen-4: 20–60 seconds. Kling: 60–240 seconds. Plan for batching — 100 clips queued overnight is fine, 100 clips needed in 30 minutes is not.
Can I use AI video commercially?
Paid tiers of Sora, Veo, Runway, Luma, and Kling grant commercial rights to output. Check the specific plan — some 'standard' tiers grant rights with watermarks; commercial-clean output requires the higher tier.
What about lip-sync and dialogue?
Veo 3 generates synced ambient audio; for proper dialogue lip-sync, layer ElevenLabs or HeyGen on top of the AI-generated video. Adds $0.10–$0.30/sec on top of the video gen cost.
Are there usage limits on Sora?
ChatGPT Plus includes a small monthly quota; the standalone Sora API tier scales with credits. Heavy users go through Azure OpenAI for enterprise terms.
How does Veo 3 differ from Veo 2?
Veo 3 added native audio generation (footsteps, ambience, dialogue lip-sync) and 1080p out-of-the-box. Roughly 50% more expensive than Veo 2 but typically halves the post-production sound design step.
Can I generate clips longer than 20 seconds?
Generate multiple 8–10 second clips and stitch in your editor. Continuity is the hard part — use image-to-video with the last frame of clip N as the first frame of clip N+1 to maintain scene consistency.
Should I buy a year's worth of credits upfront?
Generally no — providers have been launching cheaper and better models every 3–6 months. Buy 1–3 months of credits at a time to preserve flexibility.
