PromptSync: a ComfyUI node that syncs generated video playback with timed prompts
elmorinelly · reddit · 2026-09-13
A new open-source ComfyUI node, PromptSync, plays generated video on the left while auto-highlighting the matching timed prompt on the right, making it easy to spot what the model followed, skipped, or drifted on. It supports click-to-seek on timeline/waveform, separates scene text from camera/lighting/style instructions, and parses common timing formats (ranges, timestamps, numbered shots, JSON) used with MiniMax, Seedance and other video models.
