"## This workflow has a few specialities: \n \n1) The Lightx2v distil loras are only used during the low noise phase. This gives much better/dynamic generations, as the high noise phase can run unrestricted, while still giving some speed improvements during the low noise phase. \n \n2) The raw (16fps) video is not saved by default, but the frames are run through VFI to double the frame rate to 32fps, giving a much smoother playback. If you don't want that, enable \"save_output\" on the first Video Combine node and bypass VFI and the second one. \n \n3) In case you want to try to extend the video, the raw frames of either the 16fps or VFI video can be saved alongside the final video file. Enable/disable one of the Save Image nodes accordingly. It is recommended to use the RAW frames as those adhere to the Wan 16fps standard.\n \n4) The video file and frames are by default saved into a subfolder that is named after the seed used by the high noise ksampler. \n\n5) It uses the Wan MoE KSampler instead of the default one, which will automatically switch between the high and low noise models at the optimal step (see below). \n\n**Do NOT** use the distill loras together with a model that has them merged in! Read the model description to verify if that is the case or not. \n\n**Shift** \nUse 5.0 for t2v and 8.0 for i2v. Values within that range usually work well.\n \n**Width & Height** \nWan 2.2 is trained on ~1 megapixel, the default resolutions are \n1280 x 720 \n720 x 1280 \n960 x 960 \nbut in general it is very flexible about the resolution and ratio so you can use lower values if you run out of vram.\n\n**Length** \nDefault length of Wan 2.2 videos is 81 frames which corresponds to ~5 seconds of video. Usually any range between 61 and 121 frames works okay, anything further off results in incoherent results. \n \n**Boundary** \nThis corresponds to the diffusion timestep around which the model used is supposed to start using the low noise expert. For Wan 2.2 T2V, this value should be 0.875, For Wan 2.2 I2V, the value should be 0.900. Using other values might still work. \n \n## _MoE KSampler mixed distill setup_\nThis requires a specific parameter setup. \n \n**Total steps**: must be the same value as if you were not using any distil loras at all, e.g. the default 20 steps \n \n**end_at_step**: this must/should be lower to use the distill speed improvement. 15 steps is recommended, but values between 10-15 usually work. \n \n**CFG high**: As the high noise phase is running without distill, you can use CFG > 1 to enable the negative prompt. This is recommended. \n \n**CFG low**: In the low noise phase the distill lora is used, so CFG must be 1.0. \n \n## _Normal parameter setup_\n\n(Bypass distill lora loader nodes) \n \nIf you dont want to use the distill loras/models, just set \"end_at_step\" to the same value as total steps and CFG low to the same value as CFG high."
