Key takeaways
- Cheapest serious plan: Runway at $12/month. Cheapest way to make a video at
all: the per-second APIs, from $0.05 a second. - Only three of the ten give you a usable free tier — Synthesia (10 min/month),
Descript (60 min/month) and HeyGen (1-minute videos, watermarked). - Almost nobody sells you minutes. Nine of the ten bill in credits, which is
why two plans at the same price can differ threefold in what they actually produce. - If you write code, skip the platforms. $0.05 a second is roughly $3 an hour
of output — an order of magnitude below any subscription here.
“AI video platform” covers two different products that get compared as though they were one.
Some generate footage from a prompt. Others assemble a finished video — avatar, voice-over,
captions, edit — around a script. They are priced differently, they fail differently, and picking
from the wrong category is the most common way people waste a subscription.
This page ranks the platforms you sign up for. If you want the underlying models compared on
output quality instead, that is our
AI video generator comparison. Every price here was

Quick answer: which AI video platform should you use?
For talking-head and training video, Synthesia — it has the only genuinely
useful free tier at 10 minutes a month, and paid starts at $18/month billed yearly.
For editing footage you already have, Descript, free for 60 minutes a month.
For generated footage, Runway at $12/month, or the per-second APIs at $0.05 a
second if you can write a script to call them. For turning long videos into clips,
OpusClip at $15/month. The rest are variations on those four jobs.
The ten, compared
| Platform | Best for | Free tier | Entry price | Top tier |
|---|---|---|---|---|
| Runway | Generated footage, control | 125 one-time credits | $12/mo | $76/mo |
| Synthesia | Avatar and training video | 10 min/month | $18/mo yearly | Custom |
| HeyGen | Avatars, marketing | 1-min videos, watermarked | $29/mo | $149/mo |
| Descript | Editing by editing text | 60 min/month | $16/mo | $50/mo |
| InVideo | Prompt to finished video | None published | $17/mo yearly | $900/mo |
| OpusClip | Long video into clips | Watermarked, 3-day | $15/mo | $29/mo |
| Pictory | Script and blog to video | Trial only | $25/mo yearly | $199/mo |
| Fliki | Voice-led video, many languages | ~5 min, watermarked | Not published monthly | Custom |
| Veo 3.1 (API) | Highest quality generation | — | $0.05/second | $0.60/second |
| Kling / Wan (via fal) | Cheapest generation | — | $0.05/second | $0.07/second |
1. Runway — the cheapest real subscription
Generated footage with the most control on this list: motion brushes, camera direction,
image-to-video. Its pricing
page lists Standard at $12/month, Pro at $28 and Max at $76 on annual billing. The free tier
is 125 one-time credits that do not renew — enough to judge it, not to use it.
Pick it if you want generated footage and a real interface. Skip it
if you need talking-head video; that is not what it is for.
2. Synthesia — the only genuinely free start
Avatar video from a script, aimed at training and internal comms. Its
pricing gives
10 minutes of video a month free with 9 avatars and no card, which is the most
generous free tier here by a distance. Starter is $18/month billed yearly ($29 monthly) with 125+
avatars; Creator is $64/month yearly ($89 monthly) and adds API access.
Pick it if you make explainer or training video regularly. Skip it
if you want cinematic footage — avatars against backgrounds is the whole product.
3. HeyGen — avatars aimed at marketing
The same category as Synthesia, tuned for marketing rather than training.
Free allows 1-minute
videos with a watermark; Creator is $29/month with 600 credits and videos to 30 minutes; Pro
$49 with 1,000 credits; Business $149 with 1,500 credits and 60-minute videos.
Pick it if you are making short promotional video with a presenter.
Skip it if Synthesia’s free tier already covers your volume.
4. Descript — editing video by editing text
The odd one out, and the most useful for people who already film. It transcribes your footage
and lets you cut the video by deleting words.
Free gives 60 minutes a
month plus a one-time 100 AI credits; Hobbyist starts at $16/month with 10 media hours,
Creator at $24 with 30 hours, Business at $50 with 40 hours. Transcription covers 25 languages.
Pick it if you record yourself and hate editing timelines. Skip it
if you have no footage to edit — it generates very little.
5. InVideo — prompt in, finished video out
Generates a complete video, including stock footage, voice-over and captions, from a text
prompt. Plus is $17/month
billed at $200 yearly with 75 credits; Max $85 with 390; Generative $170 with 800; Elite $900
with 4,250. All paid tiers export without a watermark, and unused credits do not roll
over. No free plan is published.
Pick it if you want a finished video fast and are not precious about it.
Skip it if you need control over any individual shot.
6. OpusClip — long video into short clips
A single job done well: take a long recording and cut it into vertical clips with captions. Its
free tier exports
watermarked clips up to 1080p with a 3-day limit; Starter is $15/month and Pro $29.
Pick it if you already publish long video. Skip it if you
have nothing long to cut up — it creates nothing from scratch.
7. Pictory — script and blog to video
Turns written material into narrated video with stock footage.
Starter is $25/month billed
yearly or $29 monthly for 200 video minutes a month; Professional $35 yearly or $59 monthly for
600 minutes; Team $119 yearly or $199 monthly for 1,800. Notable as one of the few here that sells
you minutes rather than credits, which makes the bill predictable.
Pick it if you repurpose written content at volume. Skip it if
you want anything that does not look like stock footage.
8. Fliki — voice-led video across many languages
Script to narrated video, with unusually broad language coverage. Its
free plan gives 36 credits a
month — roughly 5 minutes — with a watermark and 720p output, across 300 voices and 80+ languages.
Paid tiers are sold as annual credit bundles (2,160 and 7,200 credits a year) and the page does not
publish a monthly figure, so check it before committing.
Pick it if you publish in several languages. Skip it if you
need the pricing to be legible up front.
9. Google Veo 3.1 — the quality ceiling, priced per second
Not a platform you subscribe to but an API you call, and the highest-quality generation
generally available. Priced per second of output: $0.05 on Lite at 720p, $0.08 at 1080p, $0.10 to
$0.30 on Fast, $0.40 to $0.60 on Standard. A 30-second clip therefore costs $1.50 at the cheap end
and $18 at the expensive one.
Pick it if you can call an API and want the best output per dollar.
Skip it if you want an interface.
10. Kling 2.5 Turbo Pro and Wan 2.5 — the cost floor
Reachable through fal at $0.07 and $0.05 per second respectively. At $0.05 a second, an hour of
finished output costs about $180 — but the honest number is higher, because a usable shot commonly
takes several attempts. Our per-second pricing page
covers the full table.
The credit problem
Nine of these ten bill in credits, and a credit is not a unit of anything. It is worth different
amounts of video depending on the model you pick, the resolution, and the length — which is why two
$29 plans can differ threefold in output.
Three things to check before subscribing:
- Do credits roll over? InVideo’s do not, and most do not.
- What does one minute of your actual output cost in credits? Not the headline
allowance — the number for the settings you will use. - Is commercial use included? Free tiers frequently exclude it, and that is the
line that matters if the video is for work.

Frequently asked questions
What is the cheapest AI video platform?
Runway at $12/month is the cheapest full subscription, and OpusClip at $15 the cheapest for
clipping. Cheaper still is calling a model API directly at $0.05 per second, which suits anyone
comfortable writing a short script.
Is there a genuinely free AI video platform?
Three are usable free: Synthesia at 10 minutes a month, Descript at 60 minutes a month, and
HeyGen for 1-minute watermarked videos. The rest offer a trial or a one-time credit deposit.
What is the difference between a platform and a model?
A model generates footage from a prompt. A platform wraps a model in an interface and usually
adds voice, captions and editing. You pay a model per second of output and a platform per month.
Why do credits make plans hard to compare?
Because a credit buys different amounts of video depending on model, resolution and length. Work
out the credit cost of one minute at your settings, then divide the plan price by it.
Which platform is best for talking-head videos?
Synthesia or HeyGen — both build video around an avatar reading a script. Synthesia’s free tier
is more generous; HeyGen is aimed more at marketing output.
