**一、另外还需下载下载对应模型（模型也可以文末网盘获取）。This is a digitally created CGI image featuring a stylized, anthropomorphic teddy bear as the central figure. The teddy bear is depicted as a rock musician, wearing a black leather jacket and black sunglasses. The bear's fur is a rich, light brown color, and it is holding a red electric guitar with white accents, which it appears to be strumming. The guitar has a glossy finish and visible strings.The background is a concert stage setting, bathed in warm, ambient lighting that includes spotlights creating a dynamic, energetic atmosphere. The stage is dimly lit with a mix of blue and orange hues, enhancing the dramatic effect. Surrounding the bear are various musical instruments: to the left, there is a microphone stand with a microphone positioned at the top, and to the right, a drum set is partially visible, including a bass drum, snare drum, and cymbals. The overall composition conveys a lively, rock-and-roll concert scene with the teddy bear as the charismatic performer.The CGI style is highly detailed, with realistic textures on the bear's fur and the instruments, creating a visually engaging and immersive experience.

01. 文生视频-金发女人

A woman with long brown hair and light skin smiles at another woman with long blonde hair. The woman with brown hair wears a black jacket and has a small, barely noticeable mole on her right cheek. The camera angle is a close-up, focused on the woman with brown hair's face. The lighting is warm and natural, likely from the setting sun, casting a soft glow on the scene. The scene appears to be real-life footage.



02.文生视频-瀑布探险

A man stands waist-deep in a crystal-clear mountain pool, his back turned to a massive, thundering waterfall that cascades down jagged cliffs behind him. He wears a dark blue swimming shorts and his muscular back glistens with water droplets. The camera moves in a dynamic circular motion around him, starting from his right side and sweeping left, maintaining a slightly low angle that emphasizes the towering height of the waterfall. As the camera moves, the man slowly turns his head to follow its movement, his expression one of awe as he gazes up at the natural wonder. The waterfall creates a misty atmosphere, with sunlight filtering through the spray to create rainbow refractions. The water churns and ripples around him, reflecting the dramatic landscape. The handheld camera movement adds a subtle shake that enhances the raw, untamed energy of the scene. The lighting is natural and bright, with the sun positioned behind the waterfall, creating a backlit effect that silhouettes the falling water and illuminates the mist.

二、本文将为您详细介绍LTXV的核心特点，帮助您更好地了解和应用这项技术。其扩散变换器架构确保了平滑的运动，并消除了物体变形等常见问题，提供了卓越的运动一致性。LTXV是一个仅有20亿参数的基于DiT的视频生成模型，能够实时生成高质量视频。
五、LTXV在视频生成中主体保持非常好，很小几率变形。The image is a digitally created CGI artwork depicting an anthropomorphic white rabbit character standing on a sunlit beach. The rabbit has large, expressive eyes with purple eyeshadow and wears a pair of round, gold-rimmed glasses. Its fur is smooth and white, contrasting with the colorful background. The rabbit is dressed in a casual, layered outfit consisting of a dark green and blue plaid jacket over a white T-shirt with a black graphic of a bat and the word "VAMPIRE" in purple letters. The T-shirt is tucked into a short, dark gray pleated skirt. In its right hand, the rabbit holds a tall glass of orange juice with a green straw, while its left hand rests in its pocket. The rabbit also carries a white tote bag with a floral design on its left shoulder. In the background, there are blurred figures of people, colorful tents, and umbrellas, suggesting a lively beach festival. The sky is clear with a few scattered clouds, and the overall atmosphere is vibrant and cheerful. The image combines elements of realism and cartoonish stylization, with detailed textures on the rabbit’s fur and clothing.
