    Sorry!!! While I was reworking the node, there was a node that had been disconnected at some point. We have fixed it, please re-download again!

    The addition of the ability to switch with the FLF2V model adapted to the latest version of ComfyUI, the generation of loop videos using it, and many other changes, see the blog below for more details!

    Wan2.1's advanced image to video workflow packed with a variety of features including low VRAM, high speed, long video, pixel animation, 30,60fps conversion, etc.

    • When using lora, it is not necessary to enter a triggerWord, it will be added automatically.

    • When determining the number of seconds, there is no need to calculate the number of frames; simply specify the number of seconds and the appropriate number of frames will be entered.

    • The default filename is, for example, if you use “florence” for the prompt

      wan_(name of image used)_florence_(triggerWord loraweight)_(seed)_(year_month_day)

    This error seems to occur when what is passed is empty, so my guess is that you tried to use FLF2V and got an error. Initially the video-path group is turned off (because of the Loadtext error), so turn this group on and set the video-path you want to use. (Don't forget to set Switch (image) to 7 in this case!)

    ImageBatchSplitter //Inspire
    object of type 'NoneType' has no len()
    Possible, some nodes still doesn't connect right. =(((
    Something near SD Prompt Reader, I think.
