Frame Guidance: Training-Free Guidance for Frame-Level Control in Video Diffusion Models

TL;DR:

We present Frame Guidance, a training-free framework that supports diverse control tasks using frame-level signals.

This is an official implementation of paper 'Frame Guidance: Training-Free Guidance for Frame-Level Control in Video Diffusion Models'.

🧩 Task	🔧 Base model	📂 Code
🎯Keyframe-guided, Color block, Depth, Sketch	CogX-I2V	keyframe_cogx.ipynb
🎨Stylized, 🔁Loop	CogX-T2V	others_cogx.ipynb
Wan2.1 version will be updated!
🎯Keyframe-guided, Color block, Depth, Sketch	Wan-I2V	keyframe_wan.ipynb
🎨Stylized, 🔁Loop	Wan-T2V	others_wan.ipynb

Parameter	Description	Default
--video	Input conditions for guidance (List: [img0, img1, ... imgL])	require for I2V
--guidance_lr	Schedule for guidance step size η	3e0
--guidance_step	Schedule for the number of guidance steps M	see .ipynb file
--fixed_frames	Where to apply frame-guidance (e.g., [25,48] means apply guidance on 25th and 48th frame)	require
--strength	V2V strength (It sometimes help converge faster for keyframe guidance)	0
--loss_fn	Loss design for each task [frame, style, depth, lineart, loop ...]	require
--travel_time	When we apply time-travel (stochastic) step	CogX: (5, 20), Wan: (3, 10)
