"""Temporal style: how motion and time feel, on an LTX model. One mechanism, chosen by name.
|
|
|
|
Everything but `loop` tells the model a different frame rate than the clip's (see style.py);
|
|
`loop` rolls the latent in time so the clip's end joins its start (loop.py).
|
|
|
|
`auto` reads each shot's words and picks one of these styles per shot. The module cannot see the words,
|
|
so the app makes that choice when it builds each run (app/ui/features/temporal) and sends the concrete
|
|
style; an `auto` that reaches here unresolved does nothing.
