MVDiT-VideoUFO
The target model of Membership Inference for Generative Video Models by Raina Panda and Maty Bohacek. Code: github.com/maty-bohacek/t2v-mia. Data: matybohacek/t2v-mia.
This is the MVDiT-XL/2 of OpenVid-1M (Nan et al., 2025), trained by Wang & Yang on the entirety of VideoUFO for 20 epochs (72,500 steps). The checkpoint holds the EMA weights of the final step. It has 28 transformer blocks of width 1,152 (1.07B parameters), generates 16 frames at 256ร256, and uses the stabilityai/sd-vae-ft-ema VAE and the DeepFloyd/t5-v1_1-xxl text encoder.
Since its complete training set is known, the model allows membership inference to be studied on a modern T2V architecture. Access is reviewed by the research team.
