See [VACE.md](VACE.md) for introduction guide. +- Integrated *Matanyone* tool directly inside WanGP so that you can create easily inpainting masks used in Vace +- Sliding Window generation for Vace, create windows that can last dozens of seconds +- New optimizations for old generation GPUs: Generate 5s (81 frames, 15 steps) of Vace 1.3B with only 5GB and in only 6 minutes on a RTX 2080Ti and 5s of t2v 14B in less than 10 minutes. + +### March 27, 2025 +👋 Added support for the new Wan Fun InP models (image2video). The 14B Fun InP has probably better end image support but unfortunately existing loras do not work so well with it. The great novelty is the Fun InP image2 1.3B model: Image 2 Video is now accessible to even lower hardware configuration. It is not as good as the 14B models but very impressive for its size.

With one prompt template, you can generate multiple prompts. +- New Multiple images prompts: you can now combine any number of images with any number of text prompts (need to launch the app with --multiple-images) +- New command lines options to launch directly the 1.3B t2v model or the 14B t2v model + +### March 14, 2025: Wan2.1GP v1.7 +👋 +- Lora Fest special edition: very fast loading/unload of loras for those Loras collectors around. You can also now add/remove loras in the Lora folder without restarting the app. +- Added experimental Skip Layer Guidance (advanced settings), that should improve the image quality at no extra cost. Many thanks to the *AmericanPresidentJimmyCarter* for the original implementation + +*You will need to refresh the requirements `pip install -r requirements.txt`* + +### March 13, 2025: Wan2.1GP v1.6 +👋 Better Loras support, accelerated loading Loras. + +*You will need to refresh the requirements `pip install -r requirements.txt`* + +### March 10, 2025: Wan2.1GP v1.5 +👋 Official Teacache support + Smart Teacache (find automatically best parameters for a requested speed multiplier), 10% speed boost with no quality loss, improved lora presets (they can now include prompts and comments to guide the user) + +### March 7, 2025: Wan2.1GP v1.4 +👋 Fix PyTorch compilation, now it is really 20% faster when activated + +### March 4, 2025: Wan2.1GP v1.3 +👋 Support for Image to Video with multiples images for different images/prompts combinations (requires *--multiple-images* switch), and added command line *--preload x* to preload in VRAM x MB of the main diffusion model if you find there is too much unused VRAM and you want to (slightly) accelerate the generation process. + +*If you upgrade you will need to do a `pip install -r requirements.txt` again.* + +### March 4, 2025: Wan2.1GP v1.2 +👋 Implemented tiling on VAE encoding and decoding.

many award winning movies, When writing prompts based on the user input, focus on detailed, chronological descriptions of actions and scenes. +Include specific movements, appearances, camera angles, and environmental details - all in a single flowing paragraph. +Start directly with the action, and keep descriptions literal and precise. +Think like a cinematographer describing a shot list. +Keep within 150 words. +For best results, build your prompts using this structure: +Describe the image first and then add the user input. Image description should be in first priority! Align to the image caption if it contradicts the user text input. +Start with main action in a single sentence +Add specific details about movements and gestures +Describe character/object appearances precisely +Include background and environment details +Specify camera angles and movements +Describe lighting and colors +Note any changes or sudden events +Align to the image caption if it contradicts the user text input. +Do not exceed the 150 word limit! +Output the enhanced prompt only. +""" + + +def tensor_to_pil(tensor): + # Ensure tensor is in range [-1, 1] + assert tensor.min()
