The Next Step in AI Video: Meet Wan 2.5

WaveSpeedAI,

Introduction

Over the past few years, AI video generation has gone through several waves of innovation — first with smoother motion, then with higher visual clarity.

The arrival of Veo 3 marked a crucial new phase in the industry: native audio-video synchronization. After all, without sound, can a video truly provide a complete “video experience”?

This highlights Wan 2.5 — currently the second model globally to support native A/V-synchronized generation (now available on the WaveSpeedAI platform).

We’ll analyze its core capabilities, common use cases, and real-world performance to see how this next-generation model upgrades content from simply “watchable” to truly “conversational and comprehensible.”

What makes Wan 2.5 stand out?

More affordable

Although Google recently announced price cuts, Veo 3 still remains costly overall.

In contrast, Wan 2.5 is leaner and more budget‑friendly, offering creators more options while significantly reducing production costs.

One‑pass outputs with end‑to‑end A/V sync

With Wan 2.5, you no longer need to record separate voiceovers or manually align lips for silent AI videos. Just give a clear, well‑structured prompt to generate a complete video with audio/voiceover and lip‑sync all at once. The process becomes faster and simpler.

Multilingual friendly

When prompts are in Chinese or Minor languages, Wan 2.5 reliably produces A/V‑synchronized videos. Compared to Veo 3, it often displays “unknown language” when the prompt includes Chinese or other languages.

Longer duration & more video size options

  • Length: Veo 3 maxes out at about 8 seconds; Wan 2.5 supports up to 10 seconds, providing more space for storytelling.
  • Formats: Veo 3 offers only one aspect ratio option, while Wan 2.5 supports three different video sizes to accommodate popular platforms and scenarios, enhancing publishing flexibility.

Voice‑driven reference & original sound video

Veo 3 does not support audio reference, limiting creators to silent clips or system‑generated sound.

In contrast, Wan 2.5 allows direct input of voice, sound effects, and background music, driving the video generation with precise audio cues.

Wan 2.5 vs. Veo 3

Let’s do some practical comparisons to see Wan 2.5 in action and how it differs from Veo 3.

Example 1｜Multilingual Understanding

When translating the Chinese sci-fi title “星河远征,” Wan 2.5 accurately recognizes and faithfully reproduces the Chinese elements.

In contrast, Veo 3 shows the text as “unknown language,” indicating problems with recognition and display.

Script: A cinematic opening sequence of a sci-fi movie: a spaceship travels across the galaxy, and the movie title “xingheyuanzheng · Galactic Odyssey” emerges in golden 3D letters, with flawless kerning and no distortion, floating stably in space as the camera rotates.

Example 2｜Detail Fidelity & Audio Consistency

In the “candy keyboard” case, Wan 2.5 more accurately reproduces prompt-level details.

Veo 3 produces blurrier keycap lettering and fails to deliver the requested audio elements, such as “children’s laughter.”

Script: A keyboard whose keys are made of different types of candy. Typing makes sweet, crunchy sounds. Audio: Crunchy, sugary typing sounds, delighted giggles.

Example 3｜Cinematic Camera Work & Impact

In terms of cinematic control, Veo 3 is mostly limited to fixed shots within its approximately 8-second clips, while Wan 2.5 offers dynamic camera movements that follow and adapt to the prompt more closely.

Script: A young man sits still on a subway train, surrounded by blurred figures moving rapidly. [Close-up] His eyes, barely blinking, intensify the sense of loneliness.

Example 4｜Striking Stylization Effects

Veo 3 struggles with highly stylized prompts, often defaulting to stacks of high-contrast color blocks instead of capturing the intended aesthetic.

In contrast, Wan 2.5 interprets abstract descriptors (e.g., “cheerful”) through dynamic motion, composition, and color treatment, resulting in more diverse styles and stronger artistic expression.

Script: A vibrant illustration depicts a blue macaw at the center of the composition. It uses bold, cheerful, and clear colors. Surround the macaw with a lively and colorful background that incorporates artistic graphic elements and organic shapes. Ensure the visual harmony of the entire work. The style is distinct, expressive, and full of creativity and artistry.
