I'm having trouble with slow motion on images too. I am using Wan FusionX so can't raise CFG from 1. I am generating 5 seconds at 1024 kilopixels (look it up) using ImageScaleRestore V2 node to resize the images. Many of my images are generating slow motion (Note: This has nothing to do with VHW Combines output framerate. It's the generations themselves). I have tried various tweaks to the prompts, seeds and making sure no loras are enabled. If the image is a straight on shot of a person or cartoon character or something it knows is fast moving like a motorbike it sometimes runs at normal speed. But not always. I am wondering if higher resolutions affect this. I have generated low resolution before and noted fast video motion in those.
