ComfyUI Releases Core Update With ProRes Video Export and Local MiniMax H3 Support

ComfyUI released v0.44.0, a core update that adds ProRes video saving with chroma subsampling settings and local support for MiniMax's H3 omni-modal generation model, including context windows and a latent upscaler, as the ComfyUI Dev account posted. Generated clips can now leave a graph as ProRes for an NLE timeline, and H3 generations can use context windows for longer clips and a latent upscaler inside a local workflow.

• ProRes is now a save option. Video saving now supports ProRes, with a choice of chroma subsampling setting for NLE-ready exports.
• MiniMax H3 gets local building blocks. Context window support, the H3 latent upscaler model and the Sol-H3-VAE all land in core.
• H3 Max editing tools arrive as partner nodes. Recast, Extend, Reframe, Insert, Lip Sync and Camera Control run through ComfyUI's API integrations.
• More upscalers plug in. FLUX Video Upscale V2 now targets 1080p, 2K and 4K, alongside a new Pruna P-Video Upscale node and the Wonder 4 model from Topaz Labs in the Topaz Image Enhance node.
• Dubbing, music and texture nodes join the lineup. New partner nodes cover VEED Dubbing, Sonilo Music 1.5 and Patina texture generation.

ProRes saving and VAE precision controls change what leaves the graph

Clips headed for an editing timeline can now be written as ProRes directly from the graph, with the chroma subsampling choice set at save time, according to the v0.44.0 release notes.

The release also adds a node to set the VAE compute dtype, which controls the numerical precision the VAE runs at.

Three smaller core additions sit alongside the video work:

• P-H3-Image support. The release adds support for P-H3-Image in core.
• TextGenerateV2. A new text generation node with Autogrow image inputs.
• Template updates. The workflow templates that ship with ComfyUI from Comfy Org are refreshed.

MiniMax H3 gets context windows, a latent upscaler and its own VAE locally

MiniMax describes H3 as an open model for general-purpose omni-modal generation. The company says it understands text, images, video and audio together and generates video with native stereo audio at up to 2K resolution and 15 seconds in length.

The core release adds three local pieces for running it in a graph:

• Context window support for working with longer clips
• The MiniMax-H3 latent upscaler model
• The MiniMax Sol-H3-VAE

Local H3 support and the H3 Max nodes are separate paths in this release. H3 Max arrives as a set of partner nodes, which run through ComfyUI's API integrations, covering Recast, Extend, Reframe, Insert, Lip Sync and Camera Control.

Partner nodes add 4K video upscaling, dubbing, music and texture generation

The rest of the partner-node additions are API integrations from other model makers, including two video upscaling nodes.

FLUX Video Upscale V2 adds 1080p, 2K and 4K output targets. Black Forest Labs describes its FLUX Video Upscale as FLUX 3-powered super-resolution with a precise mode and a creative detail-enhancement mode.

P-Video Upscale adds a video upscaling node from Pruna AI.

Wonder 4 joins the Topaz Image Enhance node. The Topaz Labs November product update calls Wonder 4 its all-in-one AI image enhancement model for upscaling, sharpening and denoising.

VEED Dubbing adds a dubbing node. VEED says its Dubbing API clones each speaker's voice, keeps their tone and lip-syncs the translated result.

Ideogram 4.5 Precise Edit gains context window region editing from Ideogram's AI platform.

Sonilo Music 1.5, Patina texture nodes and OpenAI's GPT-6.1 Terra and Sol models complete the new partner list.

The release also includes two housekeeping changes. WaveSpeed's FlashVSR and image upscale nodes move to Comfy Router, and ByteDance's Seedance 1.x video nodes are now marked as deprecated.
