Answers about sound, length, image input and credits.
What is Wan 2.5?+

Does Wan 2.5 generate sound?+
Yes. Every clip is generated with an audio track that can include dialogue, sound effects and background music. Describe the sounds you want in the prompt, for example on a final line that lists them.
How long are Wan 2.5 videos and what resolution do they have?+
Each video is 5 or 10 seconds long, in 720p or 1080p. Text to video offers 16:9, 9:16 and 1:1; image to video keeps the shape of your image.
Can I write prompts in Chinese?+
Yes. Prompts can be written in Chinese or English, up to 800 characters. Short prompts are expanded automatically to add detail.
What image can I use for image to video?+
Upload one JPG, PNG or WebP image; it becomes the first frame. Clear subjects and good lighting give the most stable motion.
Will text inside my image stay the same?+
Not always. Faces, products and art style hold well, but small lettering such as prices on a menu can change as the scene moves, so check text-heavy frames before you publish.
Does the lip movement match the dialogue?+
Yes. Say in the prompt who speaks and what they say, and the voice is generated in sync with the speaker's mouth and expression. Short, clear lines work best.
How should I write a Wan 2.5 prompt?+
Work in this order: subject, action, setting, camera, light, then sound. Say who is in the frame and what they do, add the camera move and mood, and end with a line listing the voices, effects and music you want.
Can Wan 2.5 make vertical videos?+
Yes. Text to video offers 9:16 for TikTok, Instagram Reels and YouTube Shorts, and a portrait image in image to video gives a portrait clip.
How many credits does Wan 2.5 use?+
720p costs 37 credits for 5 seconds and 74 credits for 10 seconds. 1080p costs 62 credits for 5 seconds and 123 credits for 10 seconds.
How is Wan 2.5 different from Wan 2.6?+
Wan 2.6 adds multi-shot storytelling and 15-second clips. Wan 2.5 is the lower-cost choice for single-shot 5 or 10 second videos with synchronized sound.
Does Wan 2.5 support multi-shot videos?+
No. Each generation is one continuous shot. To cut between several shots in one video, use the multi-shot option of Wan 2.6.
What is Wan 2.5 good for?+
It suits social clips, talking intros, product teasers, music moments and short cinematic scenes, anywhere the sound matters as much as the picture.
