Credits make most AI video plans hard to compare, so here is what one video costs on each paid plan where the pricing page makes it possible to work out:
| Tool | Cost per video or minute (monthly billing) |
|---|---|
| ContentRoof | $0.35 per video on Starter, $0.30 on Pro ($15, 50 videos) and Studio ($39, 130 videos), for videos up to 3 minutes |

| InVideo AI, HeyGen | Not stated: credits per video vary |
Why ContentRoof can be this cheap
Most AI video tools pay for every second they make: stock footage licences, AI avatars or generative video models that run on expensive graphics cards. ContentRoof's explainers are drawn instead: animated line drawings picked for each sentence, maps, counters and charts, with natural neural voices. That costs very little to make, so the free plan can be a real monthly plan instead of a trial, and paid plans start at $7.
The trade-off is honest: ContentRoof has no stock footage, no AI presenters and no cloned voices. If you need a talking avatar (Synthesia, HeyGen) or real-world footage (InVideo, Pictory), those tools are the better fit. If you want explainer videos for Shorts, TikTok or Reels, lessons or product videos in any of 11 languages, it's one of the cheapest ways to make them, with the lowest entry price here.
ContentRoof plans
| Every calendar month | Free | Starter | Pro | Studio |
|---|---|---|---|---|
| Price | $0 | $7 ($70 a year) | $15 ($150 a year) | $39 ($390 a year) |
| Explainer videos | 5 | 20 | 50 | 130 |
| Cinematic stories and brand films | 2 | 4 | 30 | No limit |
| 3D simulations | 2 | 4 | 12 | 20 |
| Resolution | 720p | 1080p | 1080p | 1080p |
Every plan makes every kind of video, in all 11 languages, with the full editor.

Of the eight tools compared here, ContentRoof has the lowest monthly price: $7 a month for 20 videos of up to 3 minutes, and a free plan with 5 videos every month. InVideo AI starts at $9; most others start between $19 and $39.

How much does an AI video cost per video?
On ContentRoof, $0.35 a video on Starter and $0.30 on Pro and Studio. Minute-based tools work out at about $1 to $1.60 per minute (Pictory, Synthesia); Zebracat is about $2.60 a video.
Why are most AI video tools priced in credits?
Because each feature costs them a different amount to run (avatars, generative video, voice cloning). Credits make the price per video hard to see; check how many credits one finished video uses before you buy.
Is ContentRoof cheaper because it's lower quality?
It's cheaper because it draws instead of licensing stock footage or running generative video models. Every video has a researched script, a natural voice, word-by-word captions and animation matched to each sentence, exported in 1080p on paid plans.
When were these prices checked?
On 8 November 2026, on each tool's own pricing page. Prices change and may differ by country.
