The seven contenders
We produced the same three deliverables in each: a 30-second product ad with a spokesperson, the same ad dubbed into three languages, and a 60-second cut-down from a 10-minute webinar.
- HeyGen — avatar ads + video translation at marketing volume
- Runway — generative footage and editing, Gen-4.5 plus 20+ third-party models
- Synthesia — corporate presenter video with governance
- Pika — playful, meme-native text-to-video clips
- Captions — mobile-first short-form ads with AI Twins
- Descript — edit-by-transcript repurposing pipeline
- Canva — brand kits, templates and social publishing with AI video
Pricing verified on official pages, October 2026:
| Tool | Free plan | Paid entry | Commercial use | Metering |
|---|---|---|---|---|
| HeyGen | 3 watermarked videos/mo | Creator $29/mo, $24/mo annual | Paid plans | Credits/min by avatar model (16–48) |
| Descript | 60 min/mo, watermarked | Hobbyist $24/mo, $16/mo annual | Paid plans | Media hours + AI credits |
| Canva | 5 lifetime silent clips | Pro $15/mo, ~$10–13/mo annual | Free tier OK (design) | Shared AI allowance; video = Ultra tier |
| Captions | Limited credits | Max $24.99/mo | Paid plans | 8 credits per 8s of avatar video |
| Runway | 125 one-time credits | Standard $15/mo, $12/mo annual | Paid plans | Gen-4.5 = 12 credits/sec |
| Synthesia | Basic: 10 min/mo, watermarked | Starter $29/mo, $18/mo annual | Paid plans | ~100 credits per video minute |
| Pika | Credit packs only | Starter $10/mo ($8 annual) | Creator $35/mo onward | 900–3,150 credits/mo |
Structural note: this category meters almost everything. Runway’s Standard 625 credits is about 52 seconds of Gen-4.5; Captions’ Max plan covers roughly 7 eight-second avatar clips; Canva’s video generation draws from the same monthly pool as Magic Write.
How we tested the best AI video generator for marketing
Each tool got the same 120-word brief for a fictional B2B SaaS product, the same three target languages (German, Japanese, Portuguese), and a 10-minute webinar recording to cut down. We scored:
- First-draft quality — was the ad usable after light edits? (blind score /10)
- Time to publishable — generation + our edit + language versions
- Cost per finished asset — subscription ÷ real outputs, including regenerations
- Commercial rights & brand fit — license on the plan we paid for, watermark policy
- Team scale — seats, brand controls, collaboration, admin
Results
| Tool | First-draft (/10) | Time to publishable | Cost per asset | Rights & brand | Team scale | Overall |
|---|---|---|---|---|---|---|
| HeyGen | 8.4 | 47 min | $1.90 | 4.6 | 4.5 | 4.4 |
| Descript | 7.6 | 39 min | $1.40 | 4.5 | 4.2 | 4.2 |
| Canva | 7.2 | 44 min | ~$1.30 | 4.4 | 4.4 | 4.2 |
| Captions | 8.2 | 34 min | ~$3.20 | 4.2 | 3.6 | 4.1 |
| Runway | 8.8 | 62 min | ~$4.80 | 4.4 | 4.0 | 4.0 |
| Synthesia | 7.4 | 51 min | ~$2.60 | 4.6 | 4.6 | 4.0 |
| Pika | 7.5 | 49 min | ~$2.10 | 3.4 | 3.0 | 3.6 |
The pattern held across all three deliverables: Runway made the most striking raw footage and the slowest workflow; Captions shipped the fastest short-form; HeyGen was the only one where all three tasks finished on a single mid-tier plan. Pika is genuinely fun and cheap — its weakness for marketing is that the commercial license only starts at Creator ($35/mo) and team features are thin.
Tool-by-tool
1. HeyGen — best overall
Avatar ads with the most photorealistic stock presenters in the test, plus Video Translate that re-lips your existing footage into 175+ languages while preserving the voice — on Creator, not gated to enterprise. Creator $24/mo annual gives 600 credits; burn depends on the avatar model (16 credits/min on an Avatar IV photo look, 48 on Avatar V), so budget by look, not by plan. Weakness: SCORM and SSO need Business at $149/mo + $20/seat.
2. Runway — best generative footage
Gen-4.5 (12 credits/second) plus Kling, Seedance, Veo and more in one workspace, with an agentic prompt-to-finished-video flow. Standard $12/mo annual is about 52 seconds of Gen-4.5 — enough for one ad, not a campaign. Commercial volume means Pro ($28) or Max ($76, 9,500 credits) plus top-ups. Note: Runway retired its old Unlimited seat, so there is no unmetered queue anymore.
3. Synthesia — best for governed corporate video
For brand-controlled explainer and enablement video, not consumer ads: ISO 27001/42001, workspace brand locking, 140+ languages, and a 2026 credit model that bills only the seconds you change. Free Basic tier is real (10 min/mo); Starter $18/mo annual removes the watermark. Weakness: 1080p ceiling, stock avatars read as synthetic, tight minute caps.
4. Pika — best for playful social clips
Fast, stylized, and cheap to enter: Starter $10/mo ($8 annual) for 900 credits, Creator $35/mo for 3,150. Watermark-free on every plan — but the commercial license starts at Creator, so Starter output is not for paid ads. Fancy tiers run $95–880/mo for unlimited parallel generation. Weakness: no team controls, and stylized output fights brand guidelines.
5. Captions — best for short-form ad volume
AI Twins and AI Ads generate talking-head and UGC-style creative from a script, then AI Edit cuts it — the fastest path to 20 vertical variants a week. Max $24.99/mo (500 credits) is about seven 8-second avatar clips; Frontier $69.99/mo (1,400 credits) for volume. Listed prices are iOS plans and only Frontier 4x can buy credit top-ups. Weakness: long-form and team admin are afterthoughts.
6. Descript — best for repurposing
Not a generator first: edit video by editing the transcript, strip filler words, apply Studio Sound, then let Underlord cut clips from your webinar. Hobbyist $16/mo annual for 10 media hours and 400 AI credits; Creator $24 for 30 hours, 4K and the full AI suite. Cheapest cost per finished asset in our test. Weakness: two meters (media hours and AI credits) push you up a tier faster than the sticker price suggests.
7. Canva — best for existing Canva teams
Video is Ultra-tier AI in Canva’s shared allowance: Pro (~$10–13/mo annual) gets up to 20 Ultra uses a month if you spend nothing else on AI — roughly 20 eight-second Veo clips. Where it wins is everything around the video: brand kit, 3.6M templates, bulk creation, and social scheduling in the tool your designers already use. AI Pass ($100/mo add-on) exists for heavy users. Weakness: the free plan gets five lifetime silent clips and no access to the real generator.
How to choose in 60 seconds
- Spokesperson ads in many languages: HeyGen, entry $24/mo annual.
- Repurposing webinars, podcasts, demos: Descript — $16/mo annual, lowest cost per asset.
- Daily vertical/UGC ad testing: Captions Max at $24.99/mo, watch the credit burn.
- Cinematic generative footage for hero campaigns: Runway Pro/Max, budget for top-ups.
- Corporate explainers under compliance: Synthesia Starter at $18/mo annual.
- Playful social clips, no paid media: Pika Starter at $8–10/mo — but upgrade to Creator ($35) before running ads.
- Already paying for Canva Pro: use it for social video; add a specialist only when drafts disappoint.
The bottom line
AI video for marketing in 2026 is no longer gated by quality — it is gated by rights and meters. Generate the same 30-second ad in HeyGen’s free tier, Captions, and your incumbent tool this week; then read the license on each plan, not just the price. Two market shifts shaped this list: OpenAI discontinued Sora (apps April 26, 2026; API September 24, 2026), so there is no OpenAI option, and every surviving vendor now meters in credits or seconds — all figures here were verified on official pricing pages, October 2026.
