PixVerse 5.5 is an advanced image-to-video model optimized for fast, high-quality short-form video generation from text and a starting image. This release continues the PixVerse lineage with improved motion smoothness, style controllability, and production-ready outputs.
Use PixVerse 5.5 on RunComfy to get production-grade performance without managing infrastructure.
https://www.runcomfy.com/models/PixVerse 5.5/api.Below are the inputs supported by PixVerse 5.5. Required fields: prompt and image_url.
Core prompts
| Parameter | Type | Default/Range | Description |
|---|---|---|---|
| prompt | string | "" | Text prompt describing the content of the generated video. Be explicit about subject, motion, camera, lighting, and mood for best results in PixVerse 5.5. |
| negative_prompt | string | "" | Terms to exclude (e.g., low quality, jitter, watermark). Helps PixVerse 5.5 avoid undesired artifacts or styles. |
| style | string | anime; [anime, 3d_animation, clay, comic, cyberpunk] | High-level aesthetic preset. Guides rendering style while preserving your prompt’s intent. |
| thinking_type | string | auto; [enabled, disabled, auto] | Prompt optimization mode. enabled refines your prompt for quality, disabled uses it verbatim, auto lets PixVerse 5.5 decide. |
Media, dimensions, and timing
| Parameter | Type | Default/Range | Description |
|---|---|---|---|
| image_url | string | (required) image URI | URL of the image used as the first frame. Choose a clean, high-resolution source to anchor motion in PixVerse 5.5. |
| aspect_ratio | string | 16:9; [16:9, 4:3, 1:1, 3:4, 9:16] | Output aspect ratio. Match your source image to minimize cropping and preserve composition. |
| resolution | string | 720p; [360p, 540p, 720p, 1080p] | Output resolution. 720p is a good balance of speed and quality; 1080p is limited to shorter durations (5 or 8 s). |
| duration | string | 5; [5, 8, 10] | Video length in seconds. Note: 1080p supports only 5 or 8 s. Longer clips cost more compute time. |
Advanced controls
| Parameter | Type | Default/Range | Description |
|---|---|---|---|
| seed | integer | 0 | Random seed for reproducibility. Use the same non-zero seed to iterate consistently in PixVerse 5.5; 0 randomizes per run. |
| generate_audio_switch | boolean | false | If true, generates audio (BGM, SFX, dialogue). Adds latency and may benefit from audio cues in the prompt. |
| generate_multi_clip_switch | boolean | false | If true, enables multi-clip generation with dynamic camera changes. Useful for multi-shot narratives; increases compute time. |
For best results with PixVerse 5.5 image-to-video:
PixVerse 5.5 returns an MP4 video; if audio is enabled, an audio track is embedded. On RunComfy’s cloud GPUs with no cold starts, most 5–8 s 720p jobs complete within tens of seconds, while 1080p or multi-clip runs typically complete within 1–2 minutes depending on load and settings.
PixVerse 5.5 excels in:
Consistent characters, objects, and scenes in any setting or angle.
Lifelike characters, realistic physics, and stunning effects.
Animate static portraits with smooth, identity-true motion using Steady Dancer's video-driven generation.
Features smooth scene transitions, natural cuts, and consistent motion.
Generate cinematic video from images with 4K detail, fluid motion, and audio sync.
Transforms reference clips into 1080p short videos with precise motion and voice alignment.
PixVerse 5.5 is the latest generation of the PixVerse image-to-video model by AiShi Technology, built with an upgraded MVL (Multimodal Vision Language) architecture. Compared to V5 or V4.5, PixVerse 5.5 introduces multi-scene camera transitions, synchronized voiceovers, and audio-visual alignment for narrative storytelling.
Yes, but you must follow the licensing terms specified by AiShi Technology. PixVerse 5.5 is generally released under a Non-Commercial or limited-use license. Using it on RunComfy does not override the model’s original license—commercial deployment of image-to-video outputs requires explicit permission from the model creator.
RunComfy runs PixVerse 5.5 on distributed cloud GPU infrastructure, enabling stable image-to-video rendering with managed concurrency. It automatically scales sessions to minimize latency, allowing multiple video generations in parallel while maintaining consistent quality and response times.
PixVerse 5.5 supports HD resolutions up to roughly 1080p for image-to-video generation. Currently, prompt tokens are capped at around 300, and it supports up to two reference inputs such as ControlNet or IP-Adapter sources. Output durations are limited to 5, 8, or 10 seconds per render.
After testing PixVerse 5.5 in the RunComfy Playground, developers can move to production via the RunComfy API. The API mirrors Playground functionality for the image-to-video pipeline. You’ll need an API key, a valid USD credit balance, and endpoint authentication to automate generation in your app or workflow.
PixVerse 5.5 integrates narrative scene sequencing, synchronized soundtracks, and camera angle variation—all generated from a single prompt. These features make its image-to-video output more cinematic and cohesive compared to competing diffusion-based tools.
On average, PixVerse 5.5 generates a 5-second image-to-video clip in 20–40 seconds on RunComfy, depending on user demand. GPU queues auto-balance workloads so concurrent tasks do not significantly delay completion times.
You hold ownership of your generated PixVerse 5.5 outputs within the limits set by its original license. Even when using image-to-video features on RunComfy, you must comply with AiShi Technology’s distribution and commercial terms. Always verify license type before publishing or selling generated content.
Local deployment of PixVerse 5.5 requires substantial GPU capacity (comparable to RTX 4090 or A100). RunComfy provides managed GPU infrastructure, which is usually more efficient and avoids setup complexity for image-to-video operations. Developers often prefer RunComfy for reliability and scale.
Yes, RunComfy provides free USD credits for first-time users of PixVerse 5.5. After that, image-to-video generation consumes paid USD credits per render. For detailed pricing, consult the 'Generation' section on the RunComfy dashboard or contact hi@runcomfy.com.
