Decart has launched MirageLSD, the first AI model capable of transforming any live video stream into completely different visual worlds in real-time. The technology processes video at under 40 milliseconds of latency while maintaining 24 frames per second, enabling streamers, filmmakers, and content creators to instantly change their visual environment.

Key capabilities include infinite-length video generation, universal input compatibility from any video source, and interactive gesture controls that let users manipulate transformed visuals through simple movements like hand waves or prop usage.

MirageLSD operates through what Decart calls Live-Stream Diffusion (LSD), an autoregressive system that generates each frame by conditioning it on the previous frame and current user prompts. This approach maintains temporal coherence across potentially infinite video lengths—addressing a major challenge that has plagued earlier AI video generators with flickering and visual inconsistencies.

The technical breakthrough centers on CUDA Megakernel optimization that delivers over 100x efficiency gains compared to standard AI video generators. This computational leap allows the system to run on consumer-grade hardware rather than requiring expensive studio equipment.

Content creators can dictate visual transformations through simple text prompts, instantly changing ordinary video calls into fantasy landscapes or transforming domestic rooms into sci-fi sets. The system responds to environmental changes in real-time, allowing creators to experiment with visual styles during live streams or recordings.

Decart's announcement demonstrates users transforming into robots or wizards, visiting tropical islands, or placing gym workouts in the Colosseum—all through prompt-driven commands.

The technology also supports "vibe-coding" for game developers, enabling rapid prototyping where creators can build basic games in under 30 minutes while MirageLSD autogenerates visual assets and world styling.

Gaming streamers can overlay visual themes onto gameplay footage, placing Grand Theft Auto in jungle environments or changing shooter maps to snowy deserts without modifying game files. The real-time processing means these transformations happen during live broadcasts rather than requiring post-production editing.

For virtual meetings and social communication, MirageLSD enables visual self-expression that goes beyond simple background replacement. Users can appear as entirely different characters or in completely transformed environments while maintaining natural movement and interaction.

The technology also opens new possibilities for virtual production workflows, allowing directors to experiment with visual styles during pre-visualization and test shoots without committing to expensive set construction or location filming.

MirageLSD represents a fundamental change in when visual effects enter the content creation process. By moving transformation capabilities from post-production into live capture, the technology enables creators to see and adjust their visual presentation in real-time rather than discovering issues after filming concludes.

This shift has immediate implications for solo creators and small teams who previously couldn't access professional-grade visual effects due to cost and technical complexity. As these capabilities become mainstream through consumer-accessible tools, expect the traditional boundaries between filmmaker roles to continue evolving toward more integrated, AI-assisted workflows.
