The discussion: Tom: It’s that trade-off between temporal stabilization and structural homogeneity that really gets me every time we look at these summaries. It feels like they're trying to solve two mutually exclusive problems simultaneously when selecting those merge candidates. Jane: Exactly. And I keep thinking about how this relates back to the coherence issues we saw in the earlier work on maintaining structural coherence when you start ignoring certain details. Are they suggesting that temporal stabilization is more important for speed, or is that just a convenient way to talk about computation? Lu: I lean towards temporal stabilization being the immediate bottleneck. If you can't stabilize the latent representation quickly enough, then no matter how structurally homogeneous the resulting image looks at a high compression ratio, the generation process itself will still be too slow. The dynamics-aware map is just a tool to make that trade-off explicit. Meng: But if we prioritize temporal stability too much, we risk losing critical structural information entirely. We’ve seen examples where aggressive stabilization leads to artifacts that destroy the prompt alignment—the foreground details get smoothed away, which defeats the purpose of keeping the important stuff intact during merging. Lalam: That brings it back to those compression ratios mentioned. If this dynamic map can intelligently shift its weighting based on the ratio, maybe it doesn't have to make a binary choice between stabilization and homogeneity. It has to be adaptive. I wonder if they’re implicitly suggesting that the "safety" of a merge candidate isn't fixed but is dependent on the compression level itself. Tom: That’s where my concern lies, Lalam. If the map is *too* sensitive to temporal dynamics, it might ignore subtle structural cues that are crucial for high-fidelity
