The biggest challenge for current video models isn't just the resolution, it's maintaining physics during fast movements.
I tested the latest Kling 2.6 update with a drone shot, transitioning from a street directly into an apartment. The update promised better texture consistency and handling of "whip pans".
My thoughts: The visual stability during the transition from outdoor to indoor is a significant improvement. Previous models often hallucinate the geometry during this kind of acceleration.
Note on audio: While the visuals have improved, Kling's native audio still very raw and unusable for professional output in my opinion. The SFX you hear in this clip was built from scratch in post-production to match the visual energy.
Tools: NanoBanana Pro, Kling and Premiere Pro.
