LTX 2.3 Extend Video
Continue an existing shot when you want more runtime without abandoning the motion and look already established.
Video extension is the continuation workflow in the LTX family. It is useful when a clip works, but the timing or editorial need changes and you want extra seconds without rebuilding the scene from scratch.

Extends an established shot instead of restarting from zero.
Keeps motion direction and scene identity more consistent.
Useful for editorial timing fixes and scene continuation.
A better fit than re-generation when the first section already works.
Production Fit
Use Cases

FAQ
Frequently Asked Questions
Short answers for the practical questions people usually ask when choosing a workflow.
Why use extend instead of regenerate?
Because the existing clip already works and only needs more runtime or a softer endpoint.
What should the prompt do here?
Use it to guide how the continuation behaves rather than redefining the entire shot.
What is the key value?
Consistency. It is about preserving what is already good.
