SVI Extend

https://github.com/vita-epfl/Stable-Video-Infinity/tree/svi_wan22

Create videos and extend them seemlessly using SVI.

Following SVI LoRAs are mandatory:

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

• switch between default behaviour, anchor_samples and end_frames within the same subgraphs

• connect an image to a part and enable the respective toggles to use end_frames or anchor_samples

NEW! v3

Extend existing videos using https://github.com/wallen0322/ComfyUI-Wan22FMLF

• enable "video extension" toggle inside the settings

• uses source video resolution by default

  • rescale video using the megapixel slider by enabling "video rescale" toggle

• use included version of the nodes from inside .zip or download the latest version straight from the git if issues arise

More info inside the workflow.

AIO i2v+t2v

All in One workflow for for basic WAN 2.2 video generation.

Following features included:

• Switch seemlessly between 2 and 3 sampler solutions

• Toggle between i2v or t2v

• Postprod

  • Facedetailer

    • uses t2v Model + LoRA for inpainting - resources needed included in workflow

  • Toggle between GIMM VFI and RIFE VFI Interpolation

  • Upscale

    • Tensorrt Upscale with Model

    • Basic Video Upscale with Model

    • RTX Video Super Resolution Upscale (insanely fast for decent quality)

  • Frame Clipper

  • Seamless Loops using custom RIFE nodes https://github.com/Artificial-Sweetener/comfyui-WhiteRabbit

Upscale + Interpolate

I recommend using this workflow instead of upscaling with the generating workflows, since you never really know what kind of results you get, ending up upscaling a bad video and wasting time. I included toggles so you can't use multiple interpolation or upscale nodes at once by mistake.

This includes:

• WAN Facedetailer

  • use any WAN 2.2 T2V low model + the following T2V LoRA:

  • lower resolution from 768 to 512 if you have VRAM issues

  • Put the following file into "ComfyUI\models\ultralytics\bbox":

• WAN Refiner (massive VRAM cost)

  • increase denoise if you want more inpainting

• Sharpen, Gamma, Brightness and Contrast control

• Frame clipper (remove unwanted frames at the start and/or end)

• GIMM VFI + RIFE VFI interpolation (I recommend GIMM VFI, much higher quality but also much slower)

  • see the following for a massive RIFE speedup

    • https://github.com/Fannovel16/ComfyUI-Frame-Interpolation/pull/102

    • https://github.com/Fannovel16/ComfyUI-Frame-Interpolation/blob/fa2f594ff0ecd4373b07aad87f1f685a0b8a771e/vfi_models/rife/__init__.py

• Tensorrt Upscale + Basic Video Upscale

  • both use basic image upscaling models

  • Tensorrt (faster than Basic Video Upscale) with AnimeSharp4x is recommended for anime

• RTX Video Super Resolution Upscale

  • insanely fast

  • decent quality

• FlashSVR + SeedVR2

  • experimental

  • Video upscale models that are more intricate than basic image upscaling models

  • haven't had great results for anime yet

  • takes a LOT longer

• Saving last frame for manual extensions

mmaudio

• added Audio combine node

  • combine audio from an existing video with the generated audio on top

  • generate nsfw audio with the nsfw model and then combine that video with another generated audio track from the base model for background noises

• removed interpolation for easier and faster audio generation - you have the following options:

  • upload raw unupscaled video to MMAudio Video node and upscaled video to Combine video node

  • upload upscaled video to both nodes but lower custom_width and custom_height of the MMAudio video node to about half for faster generation and to prevent VRAM issues

  • upload raw video to both nodes and upscale afterwards
