Its package metadata contains an invalid placeholder GitHub URL. When moving the workflow, copy the complete plugin folder or replace this node with integer width/height nodes. Quick notes If nodes appear red, install/update the required packages, restart ComfyUI, and reload the original JSON. Saved defaults: 30 fps, 300 frames (10 seconds), 9-step schedule, LCM, CFG 1.0, randomized seed. Only the first stage is enabled by default; Sampler - 2nd Upscale 1.5x is bypassed. F-Generate Audio / T-Uploaded Audio: false selects model-generated audio; true selects uploaded audio. The example image and audio reference the original author's input/whatdreamscost/ files. Replace them with your own assets. Test motion at a lower resolution first. Fix a good seed before enabling the 1.5× UHD stage.作品评论
