For your first run: choose the cafe + hiker example, then try a smaller canvas in Advanced options. Generation can take several minutes. Our minimum-size tests exceeded the free-account GPU duration limit; a PRO account or sufficient quota may be needed to generate. You can watch the published comparison above without using GPU quota. If the embedded app asks you to sign in, use “Open full demo” above.
Experimental, with room to explore
V1.5 is the model author's recommended adapter. Identity, timing, expressions, occlusions and scene details can still drift. Short continuous shots work best. This demo generates its soundtrack. The example inputs come from the V1 training dataset.
