Lightricks, the company behind LTX Video (LTXV) and LTX Studio and publisher of photo apps like Facetune, announced an update to LTXV that enables the generation of clips longer than 60 seconds. This milestone positions Lightricks as the first company to enable live-streamed, long-form AI video creation at scale, the company says. This represents an eightfold leap beyond the current industry norm of eight seconds, and is the first real-time, streaming-capable, long-form AI video model in production today. Unlike traditional models limited to short outputs, LTXV’s autoregressive streaming architecture continuously generates video in real time, enabling developers and creators to build longer, coherent stories – not just isolated clips, the company claims.
As with prior LTXV updates, this new capability will maintain open weights and be available to developers, academia, and gen AI video enthusiasts. It will also power commercial products like LTX Studio, Lightricks’ flagship creative development platform used by creators and media teams to design, iterate, and produce video projects using AI.
The new LTXV release introduces an improved autoregressive video engine that allows video clips to stream live to viewers as they are rendered. The system returns the first second of content almost instantly and continues generating forward in real time, enabling interactive, continuous narratives with full control over scene development. This paves the way for a new category of generative storytelling applications, from player-generated cutscenes and adaptive educational content to real-time AR visuals synced with live performers.
“Crossing the 60-second mark unlocks a new era for generative media,” said Zeev Farbman, co-founder and CEO of Lightricks. “LTXV is unique in its ability to create longer scenes while maintaining full control of the extended sequences, which enables coherent storytelling with visual and semantic consistency, transforming AI video from a demo or just a random clip, into a true medium with creative intent.”
LTXV’s autoregressive architecture supports both Lightricks’ 13B and mobile-friendly 2B parameter models. Creators and developers can apply pose, depth, or canny control LoRAs not only at the beginning of a prompt but continuously throughout the 30-second-plus scene. Compatible with Lightricks’ IC-LoRA infrastructure, the system also enables near real-time motion capture feeds, expanding its usability across interactive platforms.
“We’ve reached the point where AI video isn’t just prompted, but truly directed,” added Yaron Inger, co-founder and CTO. “This leap turns AI video into a longform storytelling platform, and not just a visual trick.”
