Seedance 2.0 beat Gemini Omni 1.2 Flash 4 to 2.5 in 5 tests of things video models usually get wrong. Omni was faster and cheaper: 47 seconds and $0.28 per 4-second clip, against about 2m 50s and $0.61 for Seedance. But Omni failed two tests and Seedance failed one.
The setup
Google released Gemini Omni 1.2 Flash on Nov 5, 2026. We asked Claude Opus 5.5 in Claude Code to test it against Seedance 2.0 from ByteDance.
- Models: Gemini Omni 1.2 Flash and Seedance 2.0, both at 720p
- One prompt per scene, the same for both models
- 5 scenes, 4 seconds each in the video
- Test date: Nov 6, 2026
Opus picked what video models usually break: hidden objects staying the same, solid walls, body weight, hits that connect and motion that keeps its direction. It wrote the prompts, ran the Omni clips and scored both models from the frames. We checked every score by eye and changed two of them.
The 5 tests
Each scene checks one thing that breaks often in AI video.
- Hidden objects: a golden retriever runs behind a thick oak and must come out the other side
- Solid walls: a steel ball rolls through a wooden maze and must never pass through a wall
- Body weight: a parkour runner jumps a 3-meter gap between roofs, lands and rolls
- Hits that connect: two fighters trade punches and a spinning kick in a warehouse
- Direction: a longboarder carves down a mountain road while a drone follows
The results
A pass is 1 point, a partial pass is 0.5 and a fail is 0.
| Test | Gemini Omni 1.2 Flash | Seedance 2.0 |
|---|---|---|
| Dog behind the tree | Pass | Pass |
| Ball in the maze | Fail: the ball doubles and teleports | Fail: the ball passes through a wall and rolls by itself |
| Rooftop gap jump | Pass | Pass |
| Warehouse fight | Partial: the hit reaction is off | Pass |
| Downhill longboard | Fail: the rider turns and rolls back uphill | Pass |
| Score | 2.5 | 4 |
Neither model could keep a ball inside a maze. In Seedance's clip, nobody tilts the board, yet the ball keeps rolling and goes through a wall.
The numbers
| Gemini Omni 1.2 Flash | Seedance 2.0 | |
|---|---|---|
| Time per 4-second clip | 47s | 2m 50s |
| Cost per 4-second clip | $0.28 | $0.61 |
| Generations | 8 | 5 |
| Time, all generations | 7m 20s | 18m |
| Cost, all generations | $3.06 | $3.66 |
Omni needed 3 attempts at the 8-second downhill clip and 2 at the parkour jump. Even with those retries, it spent less money and less than half the time. Its third downhill attempt used a prompt we edited to force the rider forward, so we did not use that clip in the video.
Our take
Seedance 2.0 is the safer pick when the shot has to work on the first try. Gemini Omni 1.2 Flash is about 3.6x faster and half the price per clip, but be ready to redo the fails. It matched Seedance on the dog, the jump and most of the fight. Both still break basic physics and a ball in a maze was enough to show it.
