在 ComfyUI 中制作 MiniMax H3 视频

Direct MiniMax H3 like a pro: Idea in, finished video out. A complete MiniMax H3 studio that lives in your ComfyUI.

MiniMaxH3-Studio MiniMaxH3-Studio_promo_720p30_zh_demo_v4_readme.mp4 Turn a description into a MiniMax H3 video without leaving ComfyUI. Build a prompt you can inspect, generate clips with the official H3 workflows, plan a longer video, then cut and render the result in a built-in editor. Everything lives in one ComfyUI sidebar, backed by 28 canvas nodes that share the same prompt pipeline. This is an independent custom-node project, not MiniMax's official Context-IR implementation. Latest Updates - Click to expand 1.4.1 — Newer ComfyUI frontends and clip editor fixes App Mode works with ComfyUI frontend 1.56.1 and later. These frontends add node pack details to the compiled workflow, which 1.4.0 refused with "The visible H3 graph could not be compiled." The clip editor and image crop open with ComfyUI frontend 1.57.1 and later, where 1.4.0 said the full editor was unavailable and the image could not be opened. Keys used inside them, such as Ctrl+Z, still stay there instead of changing the canvas. The sidebar, crop dialog and clip editor follow ComfyUI's light or dark palette on newer frontends too. Before, they could turn light while ComfyUI used a dark palette. The sidebar stays within the window on older and newer frontends, including after you make the window narrower. Before, it could reach past the window edge. Hover descriptions of the clip editor's icon buttons keep a readable width. A button alone in its group no longer squeezes its description into a narrow column. The empty preview monitor and empty timeline tracks now say to click a thumbnail in Media, instead of mentioning a + button the media bin does not show. Settings → Language names the Traditional Chinese option 正體中文. 1.4.0 — Directional wipes, image cropping and easier App Mode setup The clip editor adds four directional wipes, Wipe from left, Wipe from right, Wipe from top and Wipe from bottom. They appear beside Cross dissolve in the Inspector's Transition tab, and the final render closely matches the preview. A project or saved draft that uses a directional wipe needs 1.4.0 or later; earlier versions refuse it rather than dropping the wipe. The final render now encodes H.264 at a fixed, higher quality setting, so flat colours match the preview more closely. Rendered files can be larger than before. The clip editor now opens with ComfyUI frontend 1.55.11 and later, which current ComfyUI versions use. Versions of this extension up to 1.3.2 could not open it there. The clip editor now refuses a title that uses characters the bundled fonts cannot draw, such as Chinese, Japanese, Korean or emoji, and says why as soon as you add or edit it, instead of failing at the final render. The text you typed stays in place. App Mode can crop a first frame, last frame or reference image: use Crop image beside the image, drag the rectangle or pick an aspect ratio, then Apply. Starting or replacing the canvas adds ComfyUI's native Crop Image node, which you can still edit on the canvas. Start H3 App Mode and Replace canvas and start H3 App Mode now work for I2VA, FL2VA, L2VA and Ref2VA before you choose a source. They place the template's Load Image nodes, and the sidebar lists which nodes still need your images before you queue. Empty source lists explain which node to add to the main canvas, in English, Traditional Chinese and Simplified Chinese. App Mode recognizes the installed official H3 weight variants that ComfyUI's templates select, such as their video VAE and model precision variants, and prefers the template's own choice when you have it installed. Refine prompt now follows instructions that ask for camera moves or cuts between shots, while dialogue, on-screen text, reference labels and timing stay exact. If a suggestion cannot keep them, it says why instead of offering a changed prompt. Optimize prompt and Refine prompt keep the required content that is already in your prompt and never add forbidden content, as set on the H3 Hard Constraint Producer node. The GitHub repository is now named MiniMaxH3-Studio. GitHub redirects the old address, so existing clones and links keep working, and an existing installation folder can keep its name. The Comfy Registry name ComfyUI-MiniMaxH3-Studio is unchanged. 1.3.2 — App Mode finishes on current ComfyUI App Mode runs finish again on current ComfyUI versions. ComfyUI now adds extra details to each saved video, which 1.3.0 did not recognize, so a finished run could stay at "Verifying the exact saved output" indefinitely. If ComfyUI's saved-video message is missing or not recognized when the run finishes, the sidebar looks the video up in that run's ComfyUI history for up to about 16 seconds. If it still cannot be matched, the run ends with a message and Continue with native nodes instead of waiting. The H3 Reference Registry node refuses more than three audio tracks in total, including video soundtracks, before generation starts. This matches the sidebar and the native H3 limit. 1.3.0 — Ordered references, original-size assembly and clearer cut reports Ref2VA now executes linked references from the sidebar and bundled reference graphs. Select and reorder up to 9 images, 3 videos and 3 audio references, within a total of 12 files and 3 audio tracks including video soundtracks. Move or remove individual references and see their final labels before applying the graph. At least one image or video is required. Assemble at the segments' original size, 24 fps and 32 kHz stereo by default, with one final video encode. The previous 512 × 512, 30 fps, 48 kHz format remains selectable. Review a report for each cut: smooth, visible change or not measured. These bounded measurements describe the cut; they do not guarantee visual or audio continuity. A finished sequence can offer assembly when the media tools become ready later, without restarting ComfyUI. English assembly inputs now show separate segment and cut counts. 1.2.1 — Manual media tools setup and sequence assembly fix The extension no lo
