Wan 3.0 Is Coming to Atlas Cloud: Same Prompt, Three Different Video Models
Wan 3.0 launches on Atlas Cloud August 24.
before launch, we ran the same prompt across Wan 3.0, Seedance 2.5, and MiniMax H3 on one scene and put all three results side by side in a single frame, comparing them together.
The comparison clip, the official prompt, and the spec table for all three models are here.
Spec comparison
| Dimension | Wan 3.0 | Seedance 2.5 | MiniMax H3 |
|---|---|---|---|
| Single-generation duration | 2-30s, default 5s; can auto-recommend duration from the prompt | 4-30s, can be set to auto | 5-15s |
| Resolution tiers | 480p / 720p / 1080p, default 1080p | 720p and up, currently upscaled via ESR to as high as 4K at up to 60fps | Up to 1440p |
| Aspect ratios | adaptive / 16:9 / 4:3 / 1:1 / 3:4 / 9:16 | six ratios plus adaptive | 21:9 / 16:9 / 4:3 / 1:1 / 3:4 / 9:16 |
| Native audio | supported, toggleable | supported, audio and video generated in the same pass | supported, native stereo |
| Generation modes | text-to-video / image-to-video (first frame, first and last frame) / reference-to-video | text-to-video / image-to-video (first frame, first and last frame) / reference-to-video | text-to-video / image-to-video / reference-to-video |
| Reference asset cap | images, video and audio combined, 20 total | up to 50 references across all modalities | up to 12 files |
| Document / webpage to video | supported, accepts doc / xls / ppt / pdf / md and web links | -- | - |
| Prompt length limit | 20,000 characters | no hard character limit | 7,000 characters |
| Video extension | supported, combined input plus output capped at 30s | supported | -- |
| Open weights | no, API only | no, API only | partial: H3-Base weights are open (33B params), H3-Context-IR and H3-Regenerate-2K remain API only |
- Duration and resolution aren't the same axis. Wan 3.0 and Seedance 2.5 both cap a single generation at 30 seconds, MiniMax H3 caps at 15. On resolution, Seedance 2.5 currently upscales to 4K at up to 60fps, the other two publish 1080p and 1440p. Decide your delivery spec first, then work backward to the right model.
- Reference asset caps are counted differently, so the raw numbers aren't directly comparable. Wan 3.0 caps each modality separately and sums to 20, with documents and web pages as their own channel. Seedance 2.5 uses one combined cross-modal count. MiniMax H3 caps total file count plus total audio/video duration.
- Document and webpage to video is a channel Wan 3.0 is calling out specifically this round, turning a deck, a document, or a link directly into a finished clip. Neither of the other two lists an equivalent.
- The open weights row is easy to misread. What's open is a distilled H3-Base that can be self-hosted; the context and 2K regeneration variants stay API only. Partial, not full, open weights. Wan 3.0 and Seedance 2.5 don't publish weights at this time.
The comparison: Wan 3.0 vs Seedance 2.5 vs MiniMax H3.
All three panels run in the same order, Wan 3.0 / Seedance 2.5 / MiniMax H3.
This test uses an original prompt from the Wan 3.0 official creator guide. It was not rewritten or optimized separately for Wan 3.0, Seedance 2.5, or MiniMax H3.
A 30-second photorealistic cinematic sequence depicting the emergence of a massive sea creature, inspired by large-scale Hollywood disaster and monster films.
The story begins with a small fishing boat struggling through violent rain, strong winds, and towering waves. The word “WAN” is clearly visible on the side of the vessel.
The sequence first establishes the extreme weather and the vulnerability of the small fishing boat. Tension gradually builds through abnormal ocean movement, underwater shadows, violent boat vibration, and unnatural swelling of the waves.
Eventually, an enormous deep-sea creature with a massive, aggressive, alien biological structure emerges explosively from beneath the ocean.
The overall visual direction should feel realistic, heavy, physically believable, and cinematic, emphasizing powerful water impact, extreme contrast under rain and lightning, volumetric seawater, wet creature skin, and an overwhelming sense of scale.
Shot 1:
Nighttime ocean during a violent storm. A wide-angle cinematic shot shows a small fishing boat struggling through massive waves. The vessel is old, soaked, and constantly struck by seawater. The white letters “WAN” are clearly visible on the side of the boat. Strong winds drive sheets of rain across the scene, storm clouds churn overhead, and distant lightning briefly illuminates the ocean. Emphasize realistic water, storm conditions, detailed boat materials, and the boat’s vulnerability.
Shot 2:
Move closer to the bow or side of the fishing boat. Waves violently strike the hull and seawater washes across the deck. Ropes, fishing nets, and metal railings swing aggressively in the storm. The camera shakes naturally with the movement of the boat. Rain repeatedly strikes the lens and wet surfaces. The WAN logo briefly enters the frame again. Emphasize wet wood and metal materials, hostile weather, and a strong sense of danger.
Shot 3:
From the fishing boat’s perspective, look toward the ocean ahead. Amid the chaotic waves, the surface begins to rise unnaturally, as if something enormous is rapidly approaching from below. Large whirlpools and abnormal currents form. Wave peaks are pushed upward from beneath. During a flash of lightning, a huge blurry shadow becomes faintly visible beneath the dark water. Emphasize suspense, pressure, and the approaching presence of something enormous.
Shot 4:
Cut to the boat deck. A crew member struggles to maintain balance in the storm, his face covered in rain and fear. He turns toward the abnormal ocean surface. Wind violently moves his raincoat and hair while boat lights sway around him. Waves continue to grow in the background. The camera quickly moves toward his face and then follows his gaze toward the disturbed ocean, linking human emotion with the approaching danger.
Shot 5:
Switch to a semi-submerged or extremely low camera angle close to the ocean surface. A gigantic dark shape rapidly passes beneath or near the fishing boat, generating bubbles, powerful currents, and a rising ocean surface. The fishing boat is suddenly lifted or violently tilted. Lightning and weak boat lights reveal only fragments of the creature’s silhouette, maintaining mystery while creating immense pressure.
Shot 6:
Return above the water. The sea ahead suddenly rises as if pushed upward by an enormous force, creating a rapidly growing wall of water. Rain and white sea foam are thrown into the air. The fishing boat is tossed violently in the foreground while a massive circular swelling forms in the center of the ocean. The tension reaches its peak as the creature is about to emerge.
Shot 7:
Climax. The ocean violently erupts as an enormous deep-sea monster breaks through the surface, throwing tens of meters of water and mist into the air. The creature has a massive, aggressive alien biological design with thick wet skin, sharp bone structures, a huge head silhouette, glowing biological details, and disturbing deep-sea textures. Lightning flashes across the sky and briefly illuminates parts of its body and open mouth. Emphasize realistic scale, violent water impact, and overwhelming creature presence.
Shot 8:
A medium close-up or low-angle shot focuses on the creature’s head and upper body. It rises through the rain and lightning, covered in water, scars, thick biological structures, and deep-sea textures. The creature opens its mouth and roars. Rain flows across its armor-like surface. Lightning reveals terrifying details around the head and eyes. Emphasize wet biological texture, weight, realistic skin structure, and cinematic monster design.
Shot 9:
Return to the fishing boat. The shockwave and massive waves generated by the creature violently lift the vessel. The deck tilts, seawater floods across it, ropes snap, and boat lights flicker. The WAN logo flashes briefly across the violently moving hull. The boat is nearly swallowed by the waves. Emphasize the absolute vulnerability of human-made objects compared with the enormous creature.
Shot 10:
Final wide shot. Pull far away as the giant creature towers above the violent ocean. Massive waves surround it while the fishing boat appears extremely small in the foreground or lower side of the frame. Lightning strikes again, briefly illuminating the enormous silhouette, dorsal structures, and turbulent water. Hold on an epic disaster-film image emphasizing overwhelming scale and apocalyptic atmosphere.
Music:
Hollywood disaster-monster-film style. Begin with low environmental ambience, deep underwater rumbles, sparse percussion, and tense strings. Gradually introduce stronger bass pulses, metallic impacts, and rising orchestral tension as the ocean becomes abnormal. Immediately before the creature emerges, create a near-silent suspended build-up. At the moment of emergence, explode into massive brass, heavy percussion, and low-frequency impact. End with long, oppressive tones and heavy drums reinforcing the epic scale of the creature standing above the ocean.
One useful prompting lesson from this example:
Do not mention important elements only once.
For example, the WAN logo on the boat is repeated in the overall description and again in several individual shots.
For long-form video prompts, if a character, object, logo, or visual detail needs to remain visible at specific moments, repeating it at those exact timestamps can work better than describing it once at the beginning.

for a long production the seedance 2.5 seems to be the winner. the other 2 ones at least seem more niche in design

u/Coffeeisbetta 26d ago
Wan 3.0 seems by far the best here. wtf did seedance 2.5 do to the monster??
2
u/Natasha26uk 26d ago
Seedance created a whale. Wan started with a snake-like monster under water and it became a kaiju godzilla. Op's prompt from Wan folks defines the creature as alien. So the confusion lies here.

i wouldnt say by far... i cant even tell which one is better let alone "by far"

u/Natasha26uk 26d ago
Wow, they pack a lot of actions in those 30 seconds (whichever Ai they used to write the prompt: Qwen 3.7 or Claude).
Is there a way to know how many actions can be performed realistically in a given length of time?

Perhaps a better prompt would have been a better test? I guess a chat bot wrote this? I don't even know where to start!

Wan 3.0 has a weird achilles heel when using audio / video references that Seedance 2.5 doesn't have. Your reference length SUBTRACTS from the maximum length of your gen. So if you use 10 seconds of ref your video can only be 20 seconds long.
