LTX 2.3 animates a still into a 6–10 second shot at up to 2160p, with optional audio and an end frame.
LTX 2.3 animates a still into a 6, 8 or 10 second shot at 1080p, 1440p or 2160p. It is one of the few models that outputs beyond 1080p natively.
An audio toggle and an optional end frame round it out. Per-second pricing scales with the resolution tier, so the 4K-class output is there when a shot earns it.
The same engine also powers reframing, frame expansion, retakes, video from an audio track and the one-click looks (colourise, day-to-night, deblur).
Native output up to 2160p, beyond most of the catalog
End-frame control for planned motion
Per-tier pricing, so you pay for resolution only when needed

Questions
How is LTX 2.3 different from LTX-2 19B?
LTX-2 19B is the text-to-video drafting model; LTX 2.3 animates a still image at high resolution. They cover opposite ends of the workflow.
What else does the LTX 2.3 family do in Hiroska?
It reframes a clip to another aspect ratio, expands the frame outward from a prompt, re-takes a section and builds video from an audio track. It also provides the one-click looks: colourising black-and-white footage, day-to-night, deblur and compression cleanup.
Is LTX 2.3’s 2160p output native?
Yes. The top tier renders at 2160p rather than upscaling, priced per second at that tier. To upscale existing footage instead, the catalog has dedicated Topaz and SeedVR2 models.
Does LTX 2.3 generate sound?
It has an audio toggle. Sound-on renders cost more per second than silent ones.
