Changelog

[5.0.0] "Cunning Cranberry" - unreleased

A rewrite from scratch, not an update of 4.x. Same idea (a studio for video inside ComfyUI that learns from your ratings), new architecture: every feature is a module that announces itself, so a feature cannot be forgotten in the UI, a wire cannot be missed, and a failing feature module is left out while the run carries on. 4.x projects are not imported; see "Not carried over".

What it is

• A browser studio at /funpack/: timeline with one clip per scene, Composer (story in one box, cut word, templates, $variables, shortcuts), properties, media bin, preview, takes, rating, Export, Render, project wizard and guided tour.
• Models & Pipeline: the pipeline as cards. Pick files, swap or add nodes (any installed custom node), wire one node's output into another's input, import a ComfyUI workflow. The server refuses what would not build and says why.
• Modules (Settings ▸ Modules): each feature switches on or off on its own. A module that fails during a run is left out of it, the log says why, and it stays off until its code changes and ComfyUI restarts, or you turn it back on.
• Learning from ratings: a Taste key remembers ratings; the guidance, steering and prompt modules that use them start acting once they have enough ratings (a few liked clips for some, ten or more rated clips for others; some also need disliked ones) and say so when they need more.

Models

• MiniMax H3: the model v5 is built and tested around. Presets for reference to video; works text-only (no source picture). A second-pass preset exists in the code but is not offered until it has been verified.
• Stable Diffusion 1.5: experimental.
• LTX 2.x: UNTESTED. Never run on a real LTX model, and nobody plans to test it soon. Presets and the module are marked UNTESTED, and LTX runs log the same notice. You are free to try it; please report problems in Issues.

Features

• Proven: prompt markup, empty latent, second pass (the H3 preset for it is held back), loaders (diffusion model, CLIP, VAE, LoRA, checkpoint, media), cut opening, decode, save video, anchor de-staticking (ALG), randomizer, DynaShift, first-step seed search, modifiers, sampler, detail.
• Experimental: shot camera, continuity, identity transfer, negative erase, prompt enhancer, Render, taste modules (slider, guidance, prompt nudge, attention, REINS, early guidance), shot memory, decisiveness, late-branch guidance, camera move, context windows, block influence, block repeat, phrase probe, shadow negative, momentum, velocity bias, video detail, temporal style, massive-activation steering, video-to-audio coupling.
• Prompt enhancer: a language model rewrites each finished prompt. Has its own encoder pick (Composer ▸ Enhance ▸ Encoder), because H3's own encoder cannot write prose. Verified with Gemma 4.
• Auto Montage: builds a new cut at the end of the timeline from your rendered clips; originals stay untouched, and the pieces are never regenerated or rated.
• Upscale a finished render with an upscale model (.safetensors) or NVIDIA RTX Super Resolution.
• Add-ons (spaCy for automatic camera and focus, nvidia-vfx) install on the next start after you switch them on.

Not carried over

• 4.x projects and saved settings are not imported: start new projects in 5. ComfyUI workflow files can still be imported in Models & Pipeline.
• Features that never proved out stay out: plateau step-cache, block steering, NVFP4 loader.
• The unwired Engine Appearance module (the theme lives in Settings ▸ Appearance). Settings saved while it existed are ignored, not refused.

Known limits

• LTX 2.x is untested (see Models).
• .gguf text encoders need the ComfyUI-GGUF node pack and work only for architectures it understands; otherwise they are refused with a message. Gemma 4 .gguf does not work; a loader for it may come later.
• H3 start frame: in the H3 preset the scene picture sets the video's shape only; a start frame is not part of it.
• H3 second pass is held back: not offered until verified.
• Turning some modules on switches the model compiler off for the run, which costs sampling time.
