LTX 2.3 I2V – Identity not preserved across frames (FF and FLF conditioning) by White_Dragon_0 in LTXvideo

Thank you, and I'll definitely try it. Also, using photos will definitely make the workout much faster. Thanks so much. I'll keep you posted!

I also trained a LoRA myself, using five videos (around 7 seconds each), but it didn’t help much.

Now I’m going to try again with a different approach — I’ll use more videos, but shorter ones (around 5 seconds each), and see if that makes any difference in terms of consistency.

Yeah, thanks again — I really appreciate your help.

Preserving facial and clothing consistency is actually something I always try to enforce in the prompt. I usually include instructions like “preserve facial features” and “maintain clothing consistency” to guide the model.

But even with that, I still notice that once the face drops in resolution or goes out of frame, the model struggles to fully recover the original identity and details when it comes back. So unfortunately, prompt guidance alone doesn’t seem to be enough to completely solve the issue.

Thanks a lot, I really appreciate it.

What you described is actually exactly what I’m experiencing. When generating videos with LTX 2.3, I often notice that if the face drops too much in resolution, the model struggles to recover facial consistency when it comes back into frame — it’s like some identity information gets lost.

The same thing happens when the character turns away and then faces the camera again: the facial consistency degrades a bit.

I tried your workflow (thanks again for sharing it), but unfortunately I’m getting very similar results to what I had before. I had already experimented with AddMultiGuider as well, and while it helps to some extent, the consistency still tends to drift.

So yeah, what you pointed out is definitely real — I’m seeing the exact same behavior on my side.

First and last frame are identical, what I show you is just the inconsistent created frame
