Comfyui workflow for text to video, image to video, video to video, video stylize, video character replacement, clothes swapper, long video generation, low VRAM, 6 steps, all in one simple ULTIMATE workflow.

v1.20250724 Ultimate

add xtend long video generator (with controlnet+masking available)

add loopback feature

better upscale and uprte method

higher resolution for the same VRAM

Framepack killer

READ ME‼️‼️

Adjust only parameters in YELLOW nodes

prompt the GREEN node in detail

read the MUTER SWITCH GUIDE and MODEL GUIDE

check additional switchs/adjustment in YELLOW nodes

leave the BLACK nodes intact

bypass SAGE ATTENTION node if you don't have it installed

====================

MODEL GUIDE

Use VACE model + CauseVid and/or Self-Forcing lora

14B for quality

1.3B for faster inference

Change GGUF Loader node to Load Diffusion Model node for .safetensor files

===========================================================

14B VACE model GGUF + CauseVid lora (6 steps only)

or

14B FusionX VACE GGUF (CauseVid merged)

https://huggingface.co/QuantStack/Wan2.1_T2V_14B_FusionX_VACE-GGUF

===========================================================

1.3B VACE Self-Forcing model used (6 steps only, no CauseVid needed)

*1.3B VACE GGUF fails to give good result

SWITCH GUIDE

Text to video = all OFF

Image reference to video = Image1 ON

Image to video = Image1 + FLF ON

First & Last Frame to video = Image1+2+FLF ON

FLF video control = Image1+2+VidRef+FLF+control ON

V2V style change = Image1+VidRef+controlnet ON

V2V subject change = Image1+VidRef+control+SAM ON

V2V background change = same as above+invert mask

Switch ON Xtends switches according your needs (monitor progress in the group)

Loopback ON to make looping video
