About
This version updates LTX-2, and Lightricks says it improves sound and picture quality and follows the request more closely. Lightricks released it with open weights and made it for running on your own computer.
Limitations
It is made for prompts written in English.
Sound without speech, like ambience or music, can come out lower in quality.
Results depend heavily on how the prompt is worded and may not match it fully.
Good to know
One part of the model makes the picture and a separate part makes the sound, side by side.
