Nine prices for one 5-second 720p AI video, from 25 cents to $2.00
A 5-second 720p clip on Luma Ray 3.2, LTX-2.5, MiniMax H3, Runway Gen-4.5, Veo 3.1 and Sume rows, with each vendor's own arithmetic. Cheapest to dearest.

The cheapest 5-second 720p clip among the services checked this week is Veo 3.1 Lite at $0.25, then Luma Ray 3.2 at $0.30; the dearest is Veo 3.1 Standard at $2.00. The table orders the same clip across vendors and Sume's catalog, as of 2026-10-09.
| Service | Rate used | Arithmetic | 5 seconds |
|---|---|---|---|
| Veo 3.1 Lite | $0.05 per second | 5 x $0.05 | $0.25 |
| Luma Ray 3.2 | $0.30 per 5-second video | Flat total | $0.30 |
| Sume minimax-h3 (768p) | $0.075 per second | 5 x $0.075 | $0.375 |
| MiniMax-H3 (768P) | $0.08 per second | 5 x $0.08 | $0.40 |
| LTX-2.5 Fast | $0.09 per second | 5 x $0.09 | $0.45 |
| Veo 3.1 Fast | $0.10 per second | 5 x $0.10 | $0.50 |
| LTX-2.5 Pro and Runway gen4.5 | $0.12 per second (LTX); 12 credits at $0.01 per second (Runway) | 5 x $0.12 | $0.60 |
| Sume wan-3.0 (720p) | $0.125 per second | 5 x $0.125 | $0.625 |
| Veo 3.1 Standard | $0.40 per second | 5 x $0.40 | $2.00 |
Reading the table
The table is a price list, not a quality ranking. The vendor pages give no comparable quality measures and we do not invent any. The spread from $0.25 to $2.00 is eight times, but seven of the nine rows sit between $0.30 and $0.625, about a 2x range, so within that band the choice is likely to depend on inputs, audio, duration limits and moderation rather than on the price of the clip.
Runway's page lists gen4.5 at 12 credits per second, and a Runway credit is one cent, so 5 seconds is 60 credits. Luma's figure is a flat 5-second total, so it does not scale with seconds the way the others do. MiniMax direct and Runway-hosted H3 differ because Runway adds per-image credits.
Which of these Sume lists
Sume lists minimax-h3, minimax-h3-max, wan-3.0 and gemini-omni-flash-1.1 among the cheaper video rows, but not Luma, LTX, Runway or Veo. On Sume the cheapest 5-second 720p-class row is minimax-h3 at $0.375; gemini-omni-flash-1.1 at 720p is 5 x $0.125 = $0.625.
The minimax-h3 row sits under MiniMax's own $0.08 per second, so do not assume every Sume row is the vendor list plus 25 percent; read the catalog.
A hundred clips
At scale the table multiplies plainly. A hundred 5-second clips cost $25.00 at the cheapest row, $37.50 on Sume's minimax-h3, $60.00 at the Runway and LTX Pro rows, $62.50 on Sume's wan-3.0 and $200.00 at the dearest. Resolution, audio, input fees and duration limits differ by row, so match them to your brief before you read a saving into the numbers.
How to keep the comparison fair
Four things change what a clip costs without changing the headline rate: audio, input images, resolution naming and minimum durations. Veo and Omni rows on Google's page are priced with audio. MiniMax and Runway add fees for reference images. Luma sells fixed totals, so a different clip length does not scale. Sume's models each have a duration range, for example 5 to 15 seconds on minimax-h3 and 3 to 10 on gemini-omni-flash-1.1, and a request outside that range is not valid.
Before you pick a row, write down the clip length, resolution, whether you need audio and how many input images you will attach, then re-price each vendor with those four inputs. The ranking in the table can change once you do.
