I2V_T2V_Basic_for_checkpoints WF require image on t2v
Load a dummy reference image into the "Load Image" node.
The reference image is not used in T2V, but in this workflow, the size of the generated image is determined based on a resized version of the reference image.
Yes thats the drawback of having a workflow that can do both Image to video & Text to video.
ComfyUI still needs the nodes to be "loaded" or be returning ok. So the image node needs an image loaded, even if its not used in T2V mode
In the workflow image node you can just write in "example.png"
Or you can click the < or > arrows at the image loader to quickly load an image from your output folder
Probably should have that in all the workflows as a starter image (its the default dummy image for Comfy)
