Wan 2.2 i2v Comfyui Workflow :: SVI FFLF with Latent Saving and Loading — v1.0

Credit to https://civitai.com/models/2232205?modelVersionId=2820076 , whose workflows finally got SVI FFLF working for me, and I learned a lot from.

You will need the following SVI LoRAs:

High: https://huggingface.co/Kijai/WanVideo_comfy/blob/main/LoRAs/Stable-Video-Infinity/v2.0/SVI_v2_PRO_Wan2.2-I2V-A14B_HIGH_lora_rank_128_fp16.safetensors

Low: https://huggingface.co/Kijai/WanVideo_comfy/blob/main/LoRAs/Stable-Video-Infinity/v2.0/SVI_v2_PRO_Wan2.2-I2V-A14B_LOW_lora_rank_128_fp16.safetensors

v1.1 features various fixes and improvements. Notably:

There are now 2 separate workflows provided:

• 3-k-sampler workflow to get as much quality as possible out of the steps.
• MoE-k-sampler workflow, which automatically optimizes the scheduling.

Updated the latent saving and loading custom nodes:

• v2 nodes better capture the full latent data, to ensure quality is retained. (Both the v1 and v2 nodes are included in the new folder. You can simply replace the old bvga_nodes folder with the new one)

Fixed:

• SVI nodes are no longer used in the starting video segment (which in certain situations degraded quality)
• latents are no longer trimmed in segments that don't require it (which was reducing video length unnecessarily)
