PixVerse V5.5

PixVerse V5.5 sits in a slightly awkward spot in the lineage: V4.5 had the viral effect templates, V6 is the current flagship, and V5.5 is the transitional version that got the two features the later models kept - audio generation and an "enhanced reasoning" mode. It's not the newest PixVerse and it knows it, but it's the cheap, proven middle option when you want the audio-and-style feature set without paying V6's premium.

The honest pitch: if your use case is "prompt → decent video clip, possibly with sound, in a standard aspect ratio," V5.5 is the value pick. It runs the same positivePrompt-driven flow as every other PixVerse node, returns a native VIDEO, and the differences from V6 are mostly depth of features, not a night-and-day quality gap. For batch work and drafts, that's a real advantage.

Inputs that matter

positivePrompt required. The knobs worth knowing:

• providerSettings.pixverse.audio - the audio toggle, matching V6's settings.audio. On, and the clip gets a generated soundtrack. Off (default) for silent drafts, because audio costs more.
• providerSettings.pixverse.thinking - auto, enabled, or disabled. This is the "enhanced reasoning" mode: the model thinks harder about the prompt before generating. auto is the sane default; enabled buys better prompt comprehension for complex scenes at more latency, disabled trades comprehension for speed.
• providerSettings.pixverse.multiClip - multi-shot generation with varying camera angles. This is the cinematic feature, same as V6's.
• providerSettings.pixverse.style - anime, 3d_animation, clay, comic, cyberpunk, or default.
• duration - an enable-toggle plus duration_value (seconds) - a different pattern from V6's direct slider, but same idea.
• frameImages - first-frame image-to-video.
• size - the resolution/aspect dropdown from 360p to 1080p, including "from input" variants.

negativePrompt, seed, numberResults (up to 4), outputFormat (MP4/WEBM/MOV), outputQuality, and safety round out the standard set. No camera-movement or effect-template dropdowns here - that was V4.5's party trick.

How it works

The node sends pixverse:1@6 as a videoInference task through the Runware SDK. The result comes back as a native VIDEO socket for SaveVideo or whatever eats a VIDEO. Cloud-only, pay-per-run, cost on the title bar.

Install and gotchas

cd ComfyUI/custom_nodes
git clone https://github.com/Runware/ComfyUI-Runware
pip install -r ComfyUI-Runware/requirements.txt

Restart; API key via Settings → "Runware API key", RUNWARE_API_KEY, or runware auth login. Paid, minimum top-up.

The trap is version confusion: people pick up this node because it's "PixVerse" and then expect V6 features or the V4.5 template list, neither of which it has. Check the version you actually want before you queue. And thinking: enabled is a real cost/latency multiplier - it's the kind of toggle that quietly doubles your bill if you leave it on for every run. Use it for the complex prompts, leave it on auto otherwise. If you need the effect templates, go grab the V4.5 node; if you need the newest quality, V6 - this one's the reliable middle child.
