Image-to-Video Reliability Sweep โ WAN 2.7, Kling, Happy Horse
- ๐ฌFixed
Image-to-video on WAN 2.7 was silently dropping the source frame in some flows โ you'd attach a photo, ask it to animate, and the result would be a completely different subject. The variant didn't pin its mode internally, so a default kicked in that took the text-only branch and ignored the image. Now pinned correctly: your starting frame is honored every time, whether you call it from chat, Canvas, the dashboard, or the public API.

Audited every multi-mode video model for the same bug pattern. Same fix applied to Happy Horse 1.0 (both text-to-video and image-to-video variants) and Kling Video v3 (all four โ Standard Text, Standard Image, Pro Text, Pro Image). Worst case caught: Kling Pro Image was doubly broken โ would have been billed as Standard pricing AND ignored the image. All fixed.
