Example

Here's an example video generated with LTX Video Generator:

Open video link

Prompt used: > Create a 15-second cinematic product commercial for a sleek, premium TIME MACHINE device called "ChronoShift One." > > Overall style: glossy tech product ad, filmed in 4K, smooth dolly and slider shots, soft studio lighting, subtle retro‑futuristic aesthetic (think brushed aluminum, glowing rings, clean UI). The time machine looks like a compact desktop appliance about the size of a toaster: brushed metal body, circular time dial with glowing blue light, small display, and a single illuminated control knob.

Example (X/Twitter Link)

And a second run produced this one:

Open video link

Open X/Twitter post

Prompt used: > Scene tone: quiet, reflective, fragmented memory. Cinematic realism, muted natural colors. Overcast but DRY weather. No rain, no raindrops, no wet falling precipitation. > > START FRAME (0-2.5s) > Extreme close-up (85mm) of the elderly man's face. He breathes slowly. A tiny tremor in the lower eyelid. Strands of white hair drift gently in a light breeze. > Dialogue (man, barely above a whisper): > "I remember." > > Motion: micro push-in only. > > JUMP CUT 1 (2.5-5s) > Hard cut to an extreme close-up of his hands: weathered fingers rubbing a small object (a coin / pebble / ring) in his palm. > Dialogue (man): > "Not the day..." > > Motion: hands move slowly, deliberately. > > JUMP CUT 2 (5-7.5s) > Hard cut to close-up (50-85mm) of his boots stepping into soft mud at the lake edge. The movement is careful, almost hesitant. No splashing, just a quiet press into wet ground. > Dialogue (man): > "The feeling." > > Motion: one slow step, then stillness. > > JUMP CUT 3 (7.5-10s) > Hard cut to close-up of the lake surface: perfectly still water with faint ripples spreading outward (from a dropped pebble or a gentle touch). > Dialogue (man): > "It stayed."
