Features

Alibaba WAN 2.5 Text-to-Video Model

Alibaba WAN 2.5 is an advanced text-to-video model provided by Alibaba Cloud’s DashScope platform. This model generates high-quality 480p/720p/1080p videos from text prompts.

What makes it stand out?

More affordable: Wan 2.5 is more streamlined and cost-effective - reducing creator expenses and offering more options.
One-pass A/V sync: Wan 2.5 creates a fully synchronized video (audio/voiceover + lip-sync) from a single, well-structured prompt - no separate recording or manual alignment required.
Multilingual friendly: Wan 2.5 reliably processes like Chinese prompts for A/V-synced videos.
Longer duration & more video size options: Wan 2.5 delivers up to 10 seconds and 6 aspect/size options, enabling more storytelling room and publishing flexibility.
Custom Voice: Add your own audio or let the model generate one for you. Plug-and-play, easy to swap!

Designed For

Marketing teams: Fast, polished demos/tutorials—low cost, consistent style.
Global enterprises: Multilingual, lip-synced videos with subtitles for efficient localization.
Storytellers & YouTubers: Immersive narratives while maintaining cadence and quality—driving growth.

Pricing

Resolution	Price per second
480p	$0.05
720p	$0.10
1080p	$0.15

How to Use

Write your prompt.
Upload an audio file (optional) for voice/music.
Choose the video size (resolution/aspect).
Select the video duration (e.g., 5s / 10s).
Submit and wait for processing.
Preview and download the result.

Note

Audio limits

Formats: wav, mp3
Length: 3–30 seconds
File size: ≤ 15 MB

Over-limit handling

If the audio exceeds the target duration (5s or 10s), the model keeps only the first 5s/10s; the rest is discarded.
If the audio is shorter than the video duration, the extra video part is silent.
