Text-to-video
Generate videos with audio from text prompts. We recommend happyhorse-1.1-t2v. It supports 1080P resolution and clips up to 15 seconds long.
Custom audio file input
If you need to provide a custom audio file such as narration or background music, use wan2.7-t2v-2026-06-12.
Image-to-video
Create dynamic videos from static images. For first-frame image-to-video, use happyhorse-1.1-i2v. For first/last-frame stitching, use wan2.7-i2v-2026-04-25.
First-frame image-to-video
Generate video from a single image. We recommend happyhorse-1.1-i2v, which supports audio, 1080P, and 3 to 15 seconds. If you need to provide a custom audio file, use wan2.7-i2v-2026-04-25.
First/last-frame stitching for long videos
Use a first/last-frame model such as wan2.7-i2v-2026-04-25 to stitch multiple clips together. Setting the last frame of one clip as the first frame of the next creates seamless transitions, ideal for narratives, product demos, or tutorials.
Reference image-to-video
Maintain character consistency across scenes using reference images. We recommend happyhorse-1.1-r2v. If you need to provide a custom audio file to define the voice, or use video as a reference subject, use wan2.7-r2v-2026-06-12.
Video editing
Edit existing videos using text instructions for style transfer, element replacement, and other operations. We recommend happyhorse-1.0-video-edit. For effect replication or camera movement replication, use wan2.7-videoedit.
Character animation
Motion-driven character animation
To transfer motion from a reference video to a character in a static image, use wan2.2-animate-move. The background remains unchanged. The pro mode (wan-pro) produces results closer to live-action footage, while the standard mode (wan-std) is faster and more cost-effective.
Character replacement in video
To replace a character in a video with one from a source image, use wan2.2-animate-mix. It also supports pro and standard modes.
