ComfyUI-VideoHelperSuite works unnormal under version 0.24.0

[irrikrlla]

Custom Node Testing

• I have tried disabling custom nodes and the issue persists (see how to disable custom nodes if you need help)

Expected Behavior

ComfyUI-VideoHelperSuite argues invalid arguments and refuses to generate the output video

Actual Behavior

As under lower version like 0.23.x, ComfyUI-VideoHelperSuite works fine and gives the video fine

Steps to Reproduce

updated to version 0.24, and ran a video workflow, and the error occurred.
