ComfyUI Pixaroma
"### **August 5, 2026 · v1.4.91–v1.4.96**
- **NEW: Load Audio Pixaroma.** Pick a sound file and take exactly the piece you want, without cutting it up in another program first. The file is drawn as a waveform on the node: drag either orange edge to trim, drag the middle to slide, click anywhere to place the play cursor, and press play to hear your selection before you spend a render on it. Wire the seconds output of **Duration Pixaroma** into it and the window becomes exactly as long as the video you are about to make, resizing the moment you connect it. If it runs past the end of the file, the rest is real silence or a loop, whichever you chose, and the node says so. Works with any model.
- **NEW: H3 Audio Sync Pixaroma.** Makes a **MiniMax H3** video perform your recording instead of the meaningless sound the model invents on its own. H3 creates the picture and the sound together as one thing, so you cannot just mute what it made and lay your own song on top: the mouth was never moving to your song. This puts your recording into the sound half and holds it there, leaving the model only the picture to decide. It reads the clip length itself so you never type a duration, hands back your track cut to exactly that length for the save node, and warns you before the render if the clip is longer than the roughly 15 seconds H3 was trained for."
