Google presents Still-Moving Customized Video Generation without Customized Video Data Customizing text-to-image (T2I) models has seen tremendous progress recently, particularly in areas such as personalization, stylization, and conditional generation. However, expanding this progress to video generation is still in its infancy, primarily due to the lack of customized video data. In this work, we introduce Still-Moving, a novel generic framework for customizing a text-to-video (T2V) model, without requiring any customized video data. The framework applies to the prominent T2V design where the video model is built over a text-to-image (T2I) model (e.g., via inflation). We assume access to a customized version of the T2I model, trained only on still image data (e.g., using DreamBooth or StyleDrop). Naively plugging in the weights of the customized T2I model into the T2V model often leads to significant artifacts or insufficient adherence to the customization data. To overcome this issue, we train lightweight Spatial Adapters that adjust the features produced by the injected T2I layers. Importantly, our adapters are trained on "frozen videos" (i.e., repeated images), constructed from image samples generated by the customized T2I model. This training is facilitated by a novel Motion Adapter module, which allows us to train on such static videos while preserving the motion prior of the video model. At test time, we remove the Motion Adapter modules and leave in only the trained Spatial Adapters. This restores the motion prior of the T2V model while adhering to the spatial prior of the customized T2I model. We demonstrate the effectiveness of our approach on diverse tasks including personalized, stylized, and conditional generation. In all evaluated scenarios, our method seamlessly integrates the spatial prior of the customized T2I model with a motion prior supplied by the T2V model.

Tuesday, March 31, 2026, 7:44 AM: Latest infrared satellite shows the healthy plume of moisture extending from the Hawaiian Islands directly to California. However, why are we getting lighter rainfall, and why isn’t anyone talking about it? There’s a surface high we’ve had this last year with one or two storms where the surface high is south of San Diego. Currently, this surface high axis 1019mb has been extremely stubborn the last 24 hours, it’s finally starting to move southward on a trajectory into Rosarito Mexico, which is allowing for the plume axis to deepen and moisten lower and mid levels of the atmosphere a little bit throughout the afternoon and evening. The reason is so dry here with a constant offshore flow pattern for the whole month of March 2026 due to the recent historic major heat wave that we just experienced this atmospheric process takes time to cultivate. The main frontal boundary timing will be making its way into Northern and Central California from 9AM to 4PM. Secondary journey of the front will make it into Central and Southern California by 5 PM through 1 AM Wednesday. Now as the atmosphere moistens up a bit there’s also an embedded two impulses that will be associated with this frontal boundary that will move into western Santa Barbara to Western Los Angeles counties Tuesday 5PM through 4 AM Wednesday that could boost rainfall totals a little bit higher. In addition, there will definitely be a lot of stronger onshore gradients for the development of westerly winds into the Apple, Lucerne, and Antelope Valleys. This includes Las Vegas with gusts up to 35MPH - 50MPH by this late afternoon into early evening. Possible blowing dust is not out of the question on the I-15 corridor and the 1-10 freeway through Palm Springs and the Coachella Valley, beware of this hazard today. Temperatures will remain 65F - 72F the coolest it’s been since mid-February so a little taste of winter is back in our region. I’m still watching the main surface high axis movement to the south as well as all parameters to see if they fall into place by 8PM. Still a very tricky forecast even on this Tuesday. That's why I wanted to explain the atmospheric anatomy of why this forecast is so difficult not just looking at the modeling and ensembles, but the whole atmospheric picture of this forecast. #CAwx
