JonXL's Multi Wan2.2 T2I / T2V / I2V + Clip Extender Workflow (+Upscaling & Interpolation)

(+ infinite reuse last frame generation)

• Please consider using V4 here if you are an experienced ComfyUI User: https://civarchive.com/models/1872180?modelVersionId=2122194

*Downgrade node 'rgthree-comfy' to a lower version like 1.0.25052900, since their new bug prevents groups showing up in the control (bypass) panel*

*V2a - Updated, Fixed the "always resize" bug, now the resize toggle works

A multipurpose easy to use workflow for generating text to video and (infinite) image to video, using 2-3 simple toggles.

Configure all models once and then easily switch between generation modes.

(See example video of a 25 second clip generated through frame extension)

Stay tuned for future updates.

Pro tip:

Use my Quick Video Stitcher workflow in conjunction to quickly stitch two (generated) video clips together (rinse and repeat):

Versions:

V1 - Has examples for all modes

V2 - Now only uses 1 Image loader that can be refreshed + Video Frame Dump (for manual frame picking) .. recommended.

Features:

• Allows for T2V and I2V generation (using a single toggle)

• Allows for single text to image generation with resolution up to 1920x1080

• Allows for infinite video generation, by using the last frame as the input frame (for V1 turn on the toggle and generate to your heart's content :) )

• Includes upscaling and frame interpolation

• Supports (per toggle) simple resize and rescaling of input images instead of cropping

• Multi Lora loading

• Clip Vision for input image (though disabled by default)

• Sage Attention for performance

Very useful for infinite video generation, just change the prompt and click on the "Generate button" once a clip has rendered, to start using the last frame for a new clip.

• If needed, you can manually select the last frame too, if you didn't like the last clip generated. Use 'reset' if you want the latest generated frame again.

• Toggles can be found in "Step 3 - Choose parameters".

• Optionally you can quickly enable or disable frame interpolation and upscaling in the control panel above step 5 "Prompt".

• Make sure to load a random image (perhaps the one that came with this workflow zip archive) to avoid the initial error for the "Load image" node. (while the image is not needed for text 2 image or video, ComfyUI likes to complains about it)

• The example Lora used in this model can be found here: https://civarchive.com/models/1862320/wan22-t2v-lora-cartoon-style )

• This workflow does not stitch videos together, but you can use my Quick Video Stitcher Workflow to quickly stitch videos together : https://civarchive.com/models/1864873

The zip file (V1) contains one workflow and three example images.

• The workflow is preconfigured for Image to Video with Frame Extending on, 960x720x81 frames.

• You can also drop in the example images to get a pre-configuration for  T2I, T2V, I2V, I2V with frame extending.

• For T2I it is recommend to install the following custom_node to use "res_2s" + "bong tangent" sampler: https://github.com/ClownsharkBatwing/RES4LYF
