My go-to ComfyUI workflow now has more spaghetti than my most recent factory.

 (Not mine; some guy in Reddit.)

The VRAM crunch for long videos seems to rest primarily in the KSampler. There's an s2v workflow in the templates of a standard ComfyUI install that uses a tricky little module that picks up the latent and renders another chunk of video, for all of them to be stitched together at the end. With that thing, the major VRAM crunch is size of the image.

Of course there's still the decoherence issue. I've been running 40-second tests to see how badly the image decomposes over that many frames. Also found the quality is acceptable rendering at 720 and upscaling to 1024 via a simple frame-by-frame lanczos upscaler (nothing AI about it). And I'm rather proud I figured that our all by myself. At 16 fps and with Steps set down at 4 I can get a second of video for every minute the floor heater is running.

Scripting is still a big unknown. I've been experimenting with the s2v (sound to video) and as usual there are surprises. AI, after all, is an exercise in probabilities. "These things are often found with those things." It is, below the layers of agents and control nets and weighting, a next-word autocomplete.

That means it seems to have an uncanny ability to extract emotional and semantic meaning from speech. It is strictly associational; videos in the training material tended to show a person pointing when the vocal patterns of "look over there" occurred. More emergence. Cat logic, even.

So anyhow, I broke Automatic1111. Sure, it had a venv folder, but somehow Path got pointed in the wrong direction. Fortunately was able to delete python, clean install 3.10.9 inside the SD folder, Automatic1111 came back up and ComfyUI was still safe in its own sandbox. And now to try to install Kohya.
