VideoMaMa&#8217;s inference code and model weights are open-source under the Stability AI Community License. The checkpoint is available on Hugging Face at SammyLim\/VideoMaMa.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-hardware-do-i-need-to-run-video-ma-ma\"><strong>What hardware do I need to run VideoMaMa?<\/strong><\/h3>\n\n\n\n<p><\/p>\n\n\n\n<p>VideoMaMa requires an NVIDIA GPU with CUDA support. The model is built on Stable Video Diffusion, so hardware capable of running SVD will support VideoMaMa inference.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"can-video-ma-ma-work-without-sam-2\"><strong>Can VideoMaMa work without SAM2?<\/strong><\/h3>\n\n\n\n<p><\/p>\n\n\n\n<p>Yes. While SAM2-generated masks provide convenient input, VideoMaMa accepts any binary or soft mask input\u2014including manually drawn masks or outputs from other segmentation tools.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"how-does-video-ma-ma-handle-motion-blur\"><strong>How does VideoMaMa handle motion blur?<\/strong><\/h3>\n\n\n\n<p><\/p>\n\n\n\n<p>VideoMaMa excels at capturing motion blur in alpha mattes. The model learns natural motion patterns from its video diffusion prior, enabling accurate transparency estimation even for fast-moving subjects.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"whats-the-difference-between-video-ma-ma-and-mat-anyone\"><strong>What&#8217;s the difference between VideoMaMa and MatAnyone?<\/strong><\/h3>\n\n\n\n<p><\/p>\n\n\n\n<p>VideoMaMa uses generative priors from video diffusion models and focuses on mask-to-matte conversion. MatAnyone uses memory propagation for temporal consistency. VideoMaMa demonstrates stronger generalization to diverse real-world footage and better tolerance for degraded input masks.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"is-the-ma-v-dataset-publicly-available\"><strong>Is the MA-V dataset publicly available?<\/strong><\/h3>\n\n\n\n<p><\/p>\n\n\n\n<p>The MA-V dataset release status should be verified on the official project page (cvlab-kaist.github.io\/VideoMaMa), as data releases may follow different timelines than code releases.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"can-i-train-my-own-video-ma-ma-model\"><strong>Can I train my own VideoMaMa model?<\/strong><\/h3>\n\n\n\n<p><\/p>\n\n\n\n<p>Training code is currently under internal review at the research institutions.
