PromptSync: a ComfyUI node that syncs generated videos with timed prompts
elmorinelly · reddit · 2026-09-13
A new open-source ComfyUI node called PromptSync plays generated videos side-by-side with their timed prompts, auto-highlighting and scrolling the active segment so you can spot what the model followed, skipped, or where timing drifted. It supports range/timestamp/JSON prompt formats used with MiniMax, Seedance and other video models, plus waveform seeking, per-category highlighting, and metadata-aware saving.
