LTX2目前已经杀疯了,他能火,那就会推动其他的开源模型进行跟进更新,比如WAN2.X,比如前段时间发布的秒级出视频震惊!单张RTX 5090秒出高清视频,清华+生数科技TurboDiffusion加速200倍,AI视频彻底白菜化,目前Comfyui的LTX2工作流还是挺占显存的,如果不用量化版本,竟然也会偶尔爆显存?开源AI视频革命:LTX-2来了!4K+50FPS+音频同步,提示词技巧全攻略 附工作流,那现在这个LTX2的19B版本,跑上CPU +内存只需要5G显存的话,速度也相当不错,如果你安装加速没问题还会更快,1024*1024 图生视频,第一次生成10S要5分钟,第二次25秒的视频仅需要6分钟。
如果你的显卡可能显存比较小,但是CPU是的非常不错的,那可以尝试这个整合包,在不久的将来,我猜会有大厂把视频加速 + 音频同步 + 物理规律 + 2K-4K高清视频同时满足的产品打造出来。


一个温暖阳光的后院。镜头以紧凑的电影特写开始,
一对30多岁的男女面对面站着,表情严肃。
女人情绪激动,略带戏剧性,
轻声说:“就这样……爸爸失控了。我们也失去了爸爸。”
男人略显恼怒地吐了口气:“别这么戏剧化,杰西。”
停顿了一下。他瞥了一眼,然后辩解道:“他只是在玩。”
镜头慢慢向右移动,花园里的祖父戴着巨大的蝴蝶翅膀,
在空中挥舞着双臂,仿佛要起飞。
他全力挥动翅膀,大喊道:“哇!”女人捂住脸,快要哭了。
画面是面无表情的,荒谬的,又带着些许的悲剧色彩。
A warm sunny backyard.
The camera starts in a tight cinematic close-up of a woman and a man in their 30s,
facing each other with serious expressions.
The woman, emotional and dramatic, says softly,
"That's it... Dad's lost it.
And we've lost Dad."The man exhales,
slightly annoyed: "Stop being so dramatic,
Jess."A beat. He glances aside,
then mutters defensively, "He's just having fun.
"The camera slowly pans right,
revealing the grandfather in the garden wearing enormous butterfly wings,
waving his arms in the air like he's trying to take off.He shouts, "
Wheeeew!" as he flaps his wings with full commitment.
The woman covers her face, on the verge of tears. The tone is deadpan, absurd, and quietly tragic.


由于兼容了不支持加速则使用CPU,但是避免了爆显存,总共花费了11分钟,相对来说文生视频显然效果更佳,如果你觉得时间太长,那么问问自己的显卡有没有努力工作,是慢点好,还是爆显存生成不了好
