In my previous posts I talked about how you can use LTX-2 as an WAN upscaler/refiner and how to add external actors and elements references without img2vid (you need an empty scene without them and need them to come into the scene).
But why not both ? LTX-2 sux in action sequences and human interactions so the alternative at this point is wan 2.2 . But wan is lowres and has the same issue as ltx, no way for now to add actors in latent space.
So I used the same technique as for LTX2 to add actors to wan and then reinforce them in LTX-2 using the same method. Here are some results:

Idea :
Generate a very low res wan 2.2 video as reference for LTX but still pre-appending the actors and elements images at the beginning of the video,, then have the first image from the actual shot and referencing the characters from the beginning in the video. This step at 480P is very fast and good enough for characters interaction/movement coherence etc to be used as vid2vid in ltx-2. We save it at 12 fps so we can upscale with temporal upscaler in ltx.
Then in the LTX step we bring the same intro images but at highest resolution possible so ltx knows how the characters actually look like in maximum detail and paints them over the lowres wan video at at a 4x resolution. So the 480p video becomes 1440p in this case (but you can go lower if you don’t have the resources, I have an 3090 and 64GB system ram).
Both qwen image edit and flux klein were used for generating the actors, scene, zoom ins on the scene, removing characters etc.
