## Answer

LTX 2.3 Pro is the production-resolution specialist in Video Lab. Generate from text, animate a source frame, or define both ends of a shot at 1080p, 1440p, or 4K with selectable frame rates and optional audio.

## Best for

High-resolution brand footage, motion-conscious production, and shots destined for larger displays.

## Specs

- Duration: 6, 8, or 10 seconds
- Resolution: 1080p, 1440p, or 4K
- Aspect ratio: 16:9 or 9:16
- Audio: Optional generated audio
- Input support: Text prompt, Animate image, First → last

## Strengths

- Animate and first/last frames
- 1080p, 1440p, or 4K
- 24–50 fps options


## Considerations

- Uses fixed 6, 8, or 10 second durations
- Supports landscape and vertical rather than every social ratio


## Prompt tip

Choose frame rate for the intended motion feel first, then describe camera velocity and subject movement in language that matches it.

## Prompts that work

- Pick 24 fps for a filmic product hero, then describe camera velocity to match.
- 50 fps sports insert: a ball strike, 8 seconds, 4K, 16:9.
- First and last frames of a boardroom; 10 seconds, optional hush and chair scrape.
- Vertical 9:16 brand billboard at 1440p; no reference pack—describe the type treatment in the prompt.
