Give a slower reveal more time

LTX 2.3 Fast combines the speed-oriented endpoint with a broader set of duration choices in Maxsa. Use the longer options for a measured camera move through a space, keeping the subject and lighting consistent throughout the shot.

A slow reveal should finish somewhere intentional. Describe the final point of interest as well as the starting view. LoRA and model-training controls are not part of this page.

LTX 2.3 Fast prompt examples

A fuller brief for the moment when you know what you want. Copy it, or send it to the creator and make it your own.

Text to video · one continuous shot

Direct the whole shot

A long library aisle ending at a circular window. Glide steadily down the aisle toward the window, with books and wooden shelves passing at the edges.

Establish the subject clearly in the opening frame. Keep its appearance, proportions and direction of light consistent throughout. Let the action unfold at a measured pace, with no abrupt camera changes or transitions to another location.

Use a coherent foreground, middle distance and background. End with the main subject still clearly visible. No cuts, captions or added lettering. Sound direction: quiet environmental ambience appropriate to the setting, with no music or spoken dialogue.

Animate a starting image

Use the uploaded image as the starting composition. Preserve its subject, colors, material appearance and overall lighting. Glide steadily down the aisle toward the window, with books and wooden shelves passing at the edges.

Keep secondary movement restrained so the main action remains readable. Do not introduce new people, change the setting or redesign the subject. Maintain a steady pace and finish with a composition close to the starting view.

One continuous shot with no cuts or captions. Avoid sudden zooms or rapid camera rotation.

How to get started with LTX 2.3 Fast

Set the scene

Begin your LTX 2.3 Fast prompt with the subject and location. If you upload an image, use it to establish the appearance and spend the prompt on the movement you want.

Direct one action

Name what moves and how the camera behaves. “The cyclist passes from left to right; the camera stays still” is clearer than several conflicting camera directions.

Match the pace to the length

Give a short clip one readable gesture. For a longer clip, describe a gradual movement with an intentional endpoint. Check the selected duration again after changing resolution.
