Ship short videos with sound—faster—with Wan 2.5 on Vidofy
Wan 2.5 is a Wan-series multimodal generation offering from Alibaba Cloud Model Studio, surfaced as the preview model IDs wan2.5-t2v-preview (text-to-video) and wan2.5-i2v-preview (image-to-video from a first-frame image + prompt). It’s built for short-form creation where audio matters: Wan2.5 supports automatic dubbing when you don’t provide an audio URL, and it can also synchronize video to a custom audio file when you do. For version context, Alibaba Cloud notes Wan2.2 as a prior release in July 2025.
On the official API, Wan 2.5 preview endpoints are explicitly optimized around short durations: wan2.5-t2v-preview and wan2.5-i2v-preview support 5s or 10s output. Resolution is selectable by tier, including 480P / 720P / 1080P. Prompt length for Wan2.5 preview is documented at up to 1,500 characters. Output is downloadable as MP4 with H.264 encoding. If you sync with a custom audio file, supported formats include WAV/MP3, with 3–30s audio duration and up to 15 MB file size.
Vidofy.ai turns these official Wan 2.5 capabilities into a creator-friendly workflow: choose the exact Wan2.5 endpoint (T2V vs I2V), iterate with prompt rewriting/negative prompts/watermark controls (where supported), and keep your experiments organized—without having to wire regions, keys, and async polling logic yourself.

Detailed Analysis
Analysis: Sound-first storytelling vs reference-first consistency
Wan 2.5’s official API documentation is unusually explicit about audio behavior for video generation: it can create matching background audio automatically when you don’t supply an audio URL, or it can align visuals to a provided audio file. That makes Wan2.5 a strong choice for “sound drives motion” concepts—dialogue beats, music-hit edits, and timing-sensitive scenes—where you want to prototype the audiovisual rhythm directly inside the generator.
Vidu Q2’s official “Reference-to-Video” announcement, on the other hand, highlights multi-entity consistency through up to seven reference images. If your workflow starts from a character pack, product shot set, or brand reference board, that emphasis can matter more than built-in audio.
Analysis: Practical iteration—what you can reliably parameterize
Wan 2.5’s API references define concrete, controllable knobs: duration choices for wan2.5 preview endpoints (5s or 10s), resolution tiers (480P/720P/1080P), prompt length limits, and downloadable MP4 (H.264) results. Vidofy layers a clean UX on top of those parameters—so you can run repeatable prompt tests without spending time on async task polling, storage handoffs, or region/key management.

Get Your Result in 3 Simple Steps
Follow these 3 simple steps to complete your task quickly.
Step 1: Pick your Wan 2.5 mode
Choose Text-to-Video for pure prompt-based generation or Image-to-Video when you want motion anchored to a first-frame image.
Step 2: Decide whether sound leads the scene
Generate with automatic dubbing/ambient sound behavior, or provide your own audio to guide timing and alignment (where supported by the selected Wan 2.5 endpoint).
Step 3: Generate, review, iterate
Iterate on camera direction, motion, and audio cues. Save your best prompt variants, then export your preferred result.
Frequently Asked Questions
What is Wan 2.5 (officially) and who provides it?
Wan 2.5 is available as Wan2.5 preview model endpoints in Alibaba Cloud Model Studio—such as wan2.5-t2v-preview (text-to-video) and wan2.5-i2v-preview (image-to-video).
What video lengths can Wan 2.5 generate?
For the Wan2.5 preview endpoints documented in the official API references, duration options are 5s and 10s.
What resolutions are supported for Wan 2.5 video generation?
Official documentation lists 480P, 720P, and 1080P tiers for Wan2.5 preview endpoints.
Can I upload my own audio, and what are the limits?
Yes—official docs describe supplying a custom audio file URL (audio_url) for synchronization. Supported formats are WAV/MP3, with 3–30s duration and up to 15 MB file size.
How long does a generation usually take?
Alibaba Cloud’s official text-to-video API reference notes tasks are asynchronous and are typically 1 to 5 minutes (actual time depends on queue/service status).
Is there any official free quota or pricing for Wan 2.5?
Alibaba Cloud Model Studio’s official model list includes per-second pricing for wan2.5 preview models (example: $0.05/s at 480P, $0.10/s at 720P, $0.15/s at 1080P) and shows a 50-second free quota in the Singapore/International table with a 90-day validity window after activation.
