Most AI dubbing tools were designed for clips, and their pricing shows it: monthly minute quotas, per-minute overage fees, and hard caps of 30–60 minutes per video. If your content is a 90-minute lecture, a 2-hour podcast, or a 3-hour livestream, those models either refuse the upload or turn one video into a three-figure bill. aitrans.video accepts up to 3 hours in a single task, prices in credits instead of a monthly minute meter, and — just as important at this length — gives you a sentence-level workbench so one bad line at minute 97 doesn't mean redoing the job.
See it on your own footage first: dub 3 minutes free — no signup. No account, no email — a step below the usual "no credit card required."
Here is the math for one 3-hour (180-minute) video on the major platforms. Every number below comes from each vendor's public pricing pages and FAQs, verified 2026-07-03 — pricing changes, so check the date before quoting this table.
| Tool | 3-hour (180-min) video: what happens | Effective cost / limit |
|---|---|---|
| Rask AI | Creator plan ($60/mo) includes 25 min; the other 155 min bills at $3/min overage. Rask's own FAQ recommends splitting videos over 3 hours; uploads cap at 1GB. | ≈ $465 overage + $60 plan ≈ $525 for one video ($540 at the flat $3/min rate) |
| ElevenLabs | Automatic dubbing costs 3,000 credits/min without watermark (2,000 with). 180 min × 3,000 = 540,000 credits — ~90% of the Pro plan's 600k monthly credits ($99/mo). The editable Dubbing Studio rate is 5,000–10,000 credits/min → 900k–1.8M credits, beyond Pro entirely. | ≈ an entire Pro month ($99) for one automatic dub; editable dub needs a $299 Scale-class allowance |
| HeyGen | Not a cost problem — a length wall: single-video caps are 30 min (Creator $29/mo, Pro $49/mo) and 60 min (Business $149/mo). Only Enterprise removes the limit. | Can't run as one video on any self-serve plan |
| VEED | Credit-based plans (Pro $22/user/mo, Studio $39/user/mo); Studio explicitly caps Translations at 12 hr per year (~1 hr/month) on the live pricing page. | One 180-min video ≈ a full quarter of Studio's annual translation quota |
| Kapwing | Exports cap at 2 hours even on paid plans; dubbing quota is 50 min/mo (Pro $16/member/mo annual) or 200 min/mo (Business). | Can't export 3 hours; dubbing quota lasts ~4 months for one video |
| aitrans.video | One task, up to 3 hours. Credit-based: the job is priced, not the calendar month. | See pricing — no per-minute overage, no monthly minute meter |
Two honest footnotes: HeyGen's dubbing credits are actually affordable (2 credits/min for audio dubbing) — the blocker is the per-video length cap, not the rate. And VEED's plan details render client-side on their site, so we captured the figures above directly from the live pricing page with a headless browser on 2026-07-03 (Pro $22/user/mo, Studio $39/user/mo with 12 hr/yr of Translations).
Per-minute subscriptions are rational for their target customer: marketing teams localizing a stream of 2-minute clips. The model breaks when a single video is 5–10× the monthly allowance:
This is the core of how we price: long videos shouldn't be punished by the minute. Subscriptions exist for regular volume; pay-as-you-go credits exist for everyone else.
Full transparency: a 3-hour upload cap is rare, not unique — a few other tools accept videos of similar length. If raw length were the only requirement, you'd have more than one option. What's rare is pairing that length with a sentence-level editing workbench and an editable draft hand-off.
The differentiator at this length is what happens when something is wrong at hour two.
A 3-hour interview can easily run past two thousand subtitle lines. Even at a very good 98% transcription accuracy, that's dozens of misheard lines — each one translated fluently and wrong, then spoken confidently in the dub. On a one-shot tool, your options are: ship it with errors, or re-run the whole job and hope. Tools that do offer editing often price it as a premium tier — ElevenLabs' editable Dubbing Studio costs 1.7–3.3× the automatic rate (5,000–10,000 vs 2,000–3,000 credits/min, verified 2026-07-03).
On aitrans.video the workbench is the standard workflow, at one price:
Long videos usually feed a bigger workflow — a channel, a course platform, an editing team. So the output is a working set, not just a file:
From real long-form jobs, in the spirit of saving you a re-run:
Most mainstream tools cap single videos at 30–60 minutes (HeyGen: 30 min on Creator/Pro, 60 on Business) or meter by the minute (verified 2026-07-03). aitrans.video accepts up to 3 hours per video (a small number of other tools reach similar lengths); Rask sets no hard cap but recommends splitting videos over 3 hours.
It varies wildly by pricing model (verified 2026-07-03): ≈$525+ on Rask via overage, ≈540,000 ElevenLabs credits (about a full $99 Pro month) for an automatic dub, impossible as a single video on HeyGen's self-serve plans, and roughly a quarter of VEED Studio's annual translation allowance (12 hr/yr). On aitrans.video it's a single credit-priced task — see pricing.
ElevenLabs doesn't publish a hard duration cap, but at 3,000 credits/min (watermark-free automatic dubbing), 180 minutes consumes ~540,000 credits — nearly the entire 600k monthly allowance of the $99 Pro plan. The editable Dubbing Studio rate (5,000–10,000/min) puts a 3-hour job at 900k–1.8M credits. Verified 2026-07-03.
Yes — 2 hours is comfortably inside the 3-hour single-task limit, with speaker detection and per-speaker voices for multi-host formats.
Not up to 3 hours. Beyond that, yes — but one split beats the five or six that 30-minute caps force, and voice consistency holds within each task.
Chinese⇄English, both directions. That's a deliberate depth-over-breadth choice — if you need other language pairs, broad platforms like Rask (130+) or ElevenLabs (90+) are the right tools.
Yes — the 3-minute anonymous preview runs the same transcription, translation, and dubbing pipeline as full jobs (it currently demos the English→Chinese direction; Chinese→English is covered by free trial credit at signup). It's the fastest way to judge quality on your own audio instead of a demo reel.
