(Flow Denoise)Seedance 2.0 Noise Spike Remove Workflow - ComfyUI Custom node

So like everyone else, I've been deep in Seedance 2.0 lately. The quality is genuinely impressive — but after working with it extensively, I started noticing these subtle noise spikes that appear for 1-2 frames at a time. Chroma flicker, random color pops, that kind of thing. At first I tried throwing Topaz and various upscale models at it, hoping they'd clean it up. They help with general quality, sure, but those frame-level noise spikes was still there. Since I work with compositing tools (Nuke, Flame, etc..), and this reminded me of a classic technique — frame blending with motion compensation. So I decided to build it as a ComfyUI custom node that anyone can use. ------------------------------------------ What it does: - Uses optical flow (MEMFOF) to align neighboring frames, then averages them to remove temporal noise - Separates chroma and luma so you can target color flicker without killing detail - Scene-aware — handles cuts automatically. I tested 15-second clips with multiple scene transitions and it worked clean ------------------------------------------ Here's the thing — depending on the shot, these noise spikes can be really obvious or barely noticeable. But from everything I've tested, they exist in literally every generated clip. Even the Higgsfield Cinema 3.0 showcase videos on their own site still have them. For me it seems like an white-labeled version of Seedance 2.0 tho. So if you've ever had to toss a good take just because of a random color pop or flicker — give this a try. GitHub: https://github.com/AIMZ-GFX/ComfyUI-FlowDenoise Full_Demo_Video: This is still early stage and there's plenty of room for improvement. If you try it out and have ideas or feedback, I'd genuinely appreciate it. Thanks! ------------------------------------------ [workflow]
