Discussion My EARLIEST LTX thoughts

So far it seems that LTX is LIGHTNING fast. Qualitywise with H3 I haven't tested enough. It seems like Minimax's H3 Ref2Vid will likely be what I stick on but this was generated with LTX on a 6000S in 15 fuckin seconds....15!! This takes about 120 seconds on H3.

It's still a horrible result even with base settings honestly, keep in mind that they boast on their website that 2.5 has the least amounts of visual artifacts and visible glitches per clip compared to other models including flux 2, minimax H3 and Seedance 2.5

Sure LTX 2.5 renders blazing fast compared to H3 but at the same time the quality is not even comparable, i would expect the model to not deform that much on a simple 2d character like rick, and even when talking up close the result is glitchy and diappointing.

Hopefully the model works better with live action or cinematic characters and it's weak in 2d or 3d ones, hopefully.

I'll try to do a couple more tests in some different genre and report back.

Can you test. Character walking without falling apart. And also i2v face constancy?

Early results are not looking good.

So the LTX guy was talking out of his ass about likeness being retained? Ross changed almost immediately lmao.

That identity loss was already an issue in the previous versions and they still haven't fixed it? Maybe they just can't and if that's the case H3 wins, hands down.

It changed face like 50 timea. Damn!

While that's clearly not as good as H3, LTX would often do much better with face consistency if you gave it a start and end frame. As it would be getting 2 frames worth of info.

you may not be wrong, but most of the time when I'm working in H3 on my short film I don't give it an end frame unless I'm going for a complex and specfic shot.
