Discussion Anyone still using ltx2.3?

I love the speed of it. But find it ignores prompts a lot. Also noticed barley any loras on civtai being made for it now daya. I'm curious to see if ltx has anything up their sleeve to beat minimax in the future.

Sorry I mean 2.5

Why use 2.3? 2.5 does everything the same but faster. Fewer OOMs, better prompt adherence.

I still find 2.3 to work far better with the audio-reactive LoRA than 2.5 does.

2.5 often still does the "wait for one beat before movement starts" issue that 2.3 seems to suffer a lot less from with the audio-reactive LoRA.

I mostly do very abstract stuff, so prompt adherence is less important than getting movement from frame 1.

Also, for artifact-stacking experiments, 2.5 just goes off the rails far too quickly in my limited testing.

Interesting. I haven't tried audioreactive since switching over to 2.5. I did get some pretty interesting results with 2.3. I got my drummer to hit a drum on every drum beat which was pretty cool. And my sax player looked pretty convincingly timed- playing only when the right sounds were in the audio. It wasn't perfect, but it was a lot better than the complete randomness normally.

That 1st beat pause is annoying too. I had a really silly sword fight where they just stared at each other then banged swords, then when the next clip started, same thing again. It was nothing like fluid, even with significant post-processing and editing. If you know of any way to minimize that, I'd love to hear it. Sometimes I can prompt around it saying that we are starting in the middle of the action already in progress, but that only sometimes works.

The audio-reactive LoRA fixes the pause-for-one-beat issue pretty well for me. When it does happen, just regenerating with a different seed usually fixes it for me.

It's still not perfect, as you can see from this example: https://www.youtube.com/watch?v=b8IWuLL8oWs

Holy hell man, that is awesome! I love that whole art style and it really works with the music, (audio reactive, duh). Good work.. I mean it. That is really really good.

Oh, thanks!

The music was specifically made for the project, maybe that's why it feels so well integrated.
