What each video plan limits: credits, minutes, seats or concurrency
Runway, Luma, HeyGen, Synthesia and Sume gate plans on different things. A dated table of the limit that binds, from pricing pages read 2026-10-11.
Video plans do not all limit the same thing. Runway meters monthly credits and parallel generations, Luma meters credits, Synthesia meters credits shown as video minutes, HeyGen meters credits plus video length and seats, and Sume plans limit concurrent jobs while usage comes from a separate prepaid wallet. Knowing which limit binds for your workload matters more than the sticker price.
Which limit does each plan tier set?
The table lists what each vendor's own pricing page shows, read on 2026-10-11. It is not exhaustive; it picks the limits that differ most between tools.
| Tool | Plan ladder (monthly) | What scales with the plan |
|---|---|---|
| Runway | Standard $15, Pro $35, Max $95 (regular; lower if billed annually) | Credits 625 / 2,250 / 9,500; parallel generations 5 / 15 / 20 |
| Luma | Plus $30, Pro $90, Ultra $300 | Credits 10,000 / 40,000 / 150,000; Luma Agents usage 4x on Pro, 15x on Ultra |
| HeyGen | Creator $29, Pro $49, Business $149 | Credits 600 / 1,000 / 1,500; video length 30 / 30 / 60 min; team seats on Business (+$20 per seat) |
| Synthesia | Starter $29, Pro $89 | Credits 1,250 / 6,000 (about 12 / 60 minutes); guests 3 / 5 |
| Sume | Free $0, Pro $40, Startup $120, Scale $400 | Concurrent jobs 1 / 4 / 8 / 20; usage billed from the wallet at published USD rates |
When does concurrency matter more than credits?
If you render one clip at a time, concurrency never binds and the credit or wallet balance decides. If you run a batch, such as a catalog of product loops, the number of jobs allowed at once sets how long the batch takes. Runway lists parallel generations by plan and Sume lists concurrent jobs by plan, so these two are directly comparable on that axis; the other pages we read do not state a parallel-job number.
When do credits or minutes bind?
For a steady monthly volume, the allowance binds. Runway's Max plan lists one-month credit rollover, and Synthesia expresses its allowance as minutes. On Sume there is no monthly allowance to burn: the wallet balance is the limit, and you top it up from $10 to $1,000 per purchase when you need more.
A short checklist
- Count how many clips you start at once on a busy day.
- Count finished minutes per month, not credits.
- Note whether the plan also gates a feature you need, such as 4K export, custom avatars or API access (Sume's Pro plan lists API, CLI and MCP access).
- Re-read each pricing page on the day you buy.
