PixVerse Transition Video

The PixVerse Transition Video node is the morph machine: give it a first frame and a last frame, and it generates the video that flows between them. Object evolution, scene transitions, a subject transforming into something else - the model invents every intermediate frame. It's the node you reach for when "and then it turns into X" is the whole joke, or the whole transition.

Mechanically it's the standard partner-node flow. The node uploads both images to PixVerse's servers through your Comfy account, submits a transition generation with your settings, polls until it's done, and returns the finished VIDEO. Nothing runs locally, no model files, and it's billed per generation to your Comfy account credits.

The inputs that matter:

• first_frame / last_frame - the start and end images. Both required. The more visually coherent they are, the smoother the morph; wildly different subjects still work, just with more surrealism.
• prompt - describes the video and the transition. Empty is allowed, but a hint like "a fox smoothly becomes a dragon" helps the middle frames stay on-target.
• quality - 360p through 1080p, 540p default.
• duration_seconds - 5 or 8 seconds.
• motion_mode - normal or fast.
• seed - a genuine-looking seed (0–2³¹) for the generation.
• negative_prompt - optional, for undesired elements.

Single VIDEO output.

The constraints are where people get burned, and the source is explicit about them: 1080p forces 5 seconds and normal motion, and any non-5-second duration forces normal motion. So if you pick 8 seconds, fast silently becomes normal; if you pick 1080p, both duration and motion get overridden. None of this is flagged in the UI - you just get whatever the backend allows. Check the combo you picked against what you actually wanted before paying.

Also worth knowing: the sibling template node no longer feeds this node (the template input was dropped from the transition path), so styling here is prompt-only. Partner-node house rules apply: sign into your Comfy account or it fails with an auth error, and --disable-api-nodes removes the whole family from search if it bothers you.
