VISTA leverages insights from image and video classification data augmentation techniques such as CutMix, MixUp and VideoMix, which demonstrate that training on synthetic data created by overlaying or mixing multiple images or videos results in more robust classifiers. Similarly, our method spatially and temporally combines videos to create (artificial) augmented video samples with longer durations and higher resolutions, followed by synthesizing instruction data based on these new videos. Our data synthesis pipeline utilizes existing public video-caption datasets, making it fully open-sourced and scalable. This allows us to construct VISTA-400K, a high-quality video instruction-following dataset aimed at improving the long and high-resolution video understanding capabilities of video LMMs.
