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!

Ver2.00 updated contents

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)
