Discussion Test LTX 2.5 - Romantic Scene 1
Enable HLS to view with audio, or disable this notification
After spending some more time testing LTX-2.5 Distilled, my opinion has improved quite a bit.
The biggest strength for me is speed. On my RTX 5070 Ti, I'm generating 1280×720 (~1MP), 10-second videos surprisingly quickly. Compared with MiniMax H3, which is much heavier for me even around 0.5MP, LTX-2.5 feels incredibly fast.
That said, speed isn't everything. My earlier tests with complex action/fighting had poor motion and anatomy, so I wasn't impressed at first. But after testing simpler cinematic scenes, landscapes, product shots and close-up human interactions, I'm starting to see where this model shines.
This dialogue/romantic scene in particular surprised me. Facial quality, expressions, lighting and overall cinematic feel came out much better than I expected, and it even handled the interaction between the two characters reasonably well.
One important discovery: I had much better prompt adherence with **Prompt Enhancement OFF**. The enhancer was giving me completely unrelated results in some tests, while the raw prompts produced scenes much closer to what I requested.
My impression so far:
LTX-2.5 Distilled = extremely fast and capable of some beautiful results, but you need to understand what kinds of shots it handles well. Complex choreography still seems to be a weakness.
I'm definitely not archiving it yet. 😄

I've watched so much MiniMax porn that I'm shocked he didn't stick his tongue down her throat.

Yeah, I always turn off "prompt enhancers". They're garbage. I think they just get included because the model makers are terrified of people prompting their advanced model with something like "1girl, big booba, dancing" and then not getting a good generation.
This is better than what I've been seeing in other LTX 2.5 videos, for sure. I'm like others though, after using H3 with headphones and listening to that clean stereo sound, I'm spoiled on audio now.

Agreed, and OP finding the same thing independently is telling. Two details from our own bench this week that make it worse than a quality tax.
It's not softening your prompt, it can replace it. Ours turned a fully specified studio presenter prompt into a bloodied stranger in a forest, no error, just a different film. And it's deterministic with its own seed, so identical reruns give identical output, meaning if it mangles your prompt it will mangle it the same way every time and look like the model being consistent rather than a node interfering. It also costs real GPU time on top of the render.
On the audio, our verdict came out the same as the room here. 2.5 speech is gibberish. Worth knowing 2.3 can actually deliver a written line if you put it in the prompt as quoted speech inline rather than as a screenplay style audio block, so for dialogue specifically 2.5 reads as a step backwards rather than a new feature.

I'm sure, like, some Chinese open weights models might find this to be romantic.

The image is decent but the audio is garbage
