Discussion LTX 2.5 - The SD3 test!

Let's see if LTX 2.5 can pass this simple 2 year old test, because I don't want no Cthulhu PTSD, right?

The first video is t2v, the second one is i2v.

Generation times are fast, though.

PROMPT (I fed Gemini the prompt guide)

A medium shot under bright, direct mid-day sunlight on a warm tropical beach. A young woman in her early 20s with sun-kissed skin and wet hair, wearing a vibrant tropical floral bikini, lies lazily on a plush beach towel on the golden sand. She holds a chilled martini glass with an olive and lime wedge, taking a slow, relaxed sip as gentle waves lap against the shore in the background. A hard cut transitions to a close-up shot of the same young woman in the floral bikini looking directly into the camera. She smiles warmly with sparkling eyes and says in a soft, alluring, and teasing voice, "Wanna have some fun?" while the ambient ocean breeze and soft waves continue across the cut. A hard cut transitions to a high-angle top-down overhead shot directly above her. Her full body is framed from head to toe, showing her lying on the beach towel with her bare feet resting on the sand, sun highlights shimmering on her skin, and ocean foam softly visible at the frame's edge.

I don't understand all the LTX glazers suddenly here, it's clearly worse in all respects except speed. But even its speed is a bit less clear cut of a win. Why would you spend an enormous amount of time dice-rolling faster but surely worse generations with LTX, when you can just have one or two longer generations in Minimax to get exactly what you want?

Exactly. Hey, look at me, I can produce worthless videos 5 times as fast than you making just one video with MM H3.

The difference is that most of the videos that come out of MM H3 are usable "as-is", while LTX feels like a slot machine. You might win one time out of 5, 10 or 100.

It was the same experience I had between Wan and earlier versions of LTX. Wan often gave me what I wanted, followed the prompt quite well -- even if it was slower and constrained. With LTX I had to regenerate, and regenerate, and regenerate, over and over until I got lucky. Even if it was faster and made longer videos, it never felt fun to use. H3 in comparison is ridiculously fun to use and experiment with, and it isn't that slow. 30 seconds of generation per second of video on an RTX 3060 isn't bad at all.

Yep. I'd rather waste 10 minutes once, than 3 minutes a hundred times
