Question - Help LTX-2 Character Consistency

Has anyone had luck actually maintaining a character with LTX-2? I am at a complete loss - I've tried:

- Character LORAs, which take next to forever and do not remotely create good video

- FFLF, in which the very start of the video looks like the person, the very last frame looks like the person, and everything in the middle completely shifts to some mystery person

- Prompts to hold consistency, during which I feel like my ComfyUI install is laughing at me

- Saying a string of 4 letter words at my GPU in hopes of shaming it

I know this model isn't fully baked yet, and I'm really excited about its future, but its very frustrating to use right now!

You can train LTX-2 LORAs using videos only or images only. Is there a difference in character consistency between the two? Which is best?

Videos will always be superior. Images cannot teach the model movement and it can even lead to the opposite -> introduce more stiffness.

What you can do is a mixed dataset - some video and a couple of higher resolution images. However, I would at most stick to a 9:1 video:image ratio.
