AVCaption vs api.video
api.video is the developer’s video platform. The pitch is “video as a service via clean APIs and SDKs”, and the team has shipped client libraries for Node, Python, Go, PHP, Ruby, Java, Swift, Kotlin, React, React Native, and Flutter.
The free encoding is unique. The storage and bandwidth pricing is not.

How they price
This is the comparison.
api.video โ free encoding, paid storage and bandwidth
Encoding really is free on api.video. The entire pricing model shifts onto storage (~$0.45/GB/month at the published rate) and bandwidth (metered per GB delivered).
For a tiny library (say 10 GB total) with low traffic, this can be cheaper than any flat tier โ you pay pennies per month.
For a real production library, the math runs the other way. Worked example for a 5 TB course or content library:
- Storage: 5,120 GB ร $0.45/GB โ $2,300/month before a single view
- Bandwidth: depends on viewership. A modest 5 million minutes of playback at typical 1080p bitrate โ another $1,000โ$3,000/month
- Total: realistically $3,000โ$5,000/month for a moderately active 5 TB library
AVCaption โ $100 per month, fixed
AVCaption Premium is $100/mo flat per 5 TB, regardless of viewership. Encoding, bandwidth, and CDN delivery all included. Whether your video gets 100 views or 10 million views, the bill does not move.
That is roughly a 30ร difference at 5 TB scale โ not a 30% difference. The shape of your bill matters more than the headline.
The pricing rule of thumb
| If your library is… | Choose |
|---|---|
| Under 100 GB and growing slowly | api.video โ pennies per month |
| 200 GB+ and growing | AVCaption Premium โ flat $100 wins |
| Bursty viewership / launch traffic | AVCaption โ bill doesn’t spike with views |
| You need polished SDKs in 10+ languages | api.video โ best-in-class |
Where api.video is genuinely better
This page would not be honest without saying it: api.video wins in a few important categories.
- SDK breadth. api.video ships official client libraries for ~10 languages including React Native, Flutter, Swift, and Kotlin. AVCaption today is REST-API + iframe embed; no mobile SDKs.
- Developer onboarding. The api.video docs and sandbox are among the cleanest in the category. If you’re prototyping a video product over a weekend, the friction is lower.
- Free encoding for tiny libraries. Under 50โ100 GB with low traffic, api.video’s bill is genuinely smaller than any flat tier. For an MVP, that matters.
- Live streaming. api.video supports live with low-latency HLS. AVCaption is on-demand only as of 2026-05-02.
If any of those are deal-breakers, api.video is the right choice.
Where AVCaption is genuinely better
- Predictable bill at scale. Flat tiers vs. variable storage + bandwidth. Above ~200 GB the math flips hard.
- Multi-key rotating encryption by default โ stronger than single-key AES-128 without paying for DRM.
- AI subtitle pipeline โ multi-track player playback with bilingual (dual-language) display, plus the Studio tool for creating subs from scratch.
- Free tier with unlimited storage โ useful for prototyping; api.video’s trial credits evaporate fast.
- Flat $100 per 5 TB regardless of viewership โ bursty launch traffic doesn’t move the bill.
When to choose api.video
- You’re a developer prototyping with the cleanest API on the market.
- Your library is very small (under 100 GB) and you don’t expect rapid growth.
- You ship in many languages and want SDK-first integration.
- You need live streaming today.
When to choose AVCaption
- Your library will grow past 200 GB.
- You need a player that displays two subtitle languages simultaneously for bilingual learners.
- You want flat predictable pricing โ the bill doesn’t move when a video goes viral.
- You want a free tier with unlimited storage.
- You sell access to gated or paid content and want dynamic per-viewer watermarks.
Migration: api.video to AVCaption
For libraries under 1 TB, most teams complete migration in a single working day:
- List your videos via api.video’s REST API or dashboard export.
- Pull source MP4/MKV files (api.video stores originals).
- Upload to AVCaption via the chunked uploader (drag-and-drop with resume support).
- (Enterprise) Script the upload + token-mint via AVCaption’s REST API.
- Update your embed iframes โ AVCaption issues a fresh embed token per video.
Most teams keep the api.video account active for two weeks after cutover as a fallback before tearing it down.
Verdict
api.video is excellent for prototyping, very small libraries, and teams that need polished SDKs across many languages. AVCaption is excellent for actual production workloads where the bill needs to stay flat as the library and audience grow.
If your library is past 200 GB, spin up an AVCaption account and run the math against your last api.video invoice. The flat $100 tier usually pays for itself inside the first month.
