Spatio-temporal consistency is a critical research topic in video generation.
A qualified generated video segment must ensure plot plausibility and coherence
while maintaining visual consistency of objects and scenes across varying
viewpoints. Prior research, especially in open-source projects, primarily
focuses on either temporal or spatial consistency, or their basic combination,
such as appending a description of a camera movement after a prompt without
constraining the outcomes of this movement. However, camera movement may
introduce new objects to the scene or eliminate existing ones, thereby
overlaying and affecting the preceding narrative. Especially in videos with
numerous camera movements, the interplay between multiple plots becomes
increasingly complex. This paper introduces and examines integral
spatio-temporal consistency, considering the synergy between plot progression
and camera techniques, and the long-term impact of prior content on subsequent
generation. Our research encompasses dataset construction through to the
development of the model. Initially, we constructed a DropletVideo-10M dataset,
which comprises 10 million videos featuring dynamic camera motion and object
actions. Each video is annotated with an average caption of 206 words,
detailing various camera movements and plot developments. Following this, we
developed and trained the DropletVideo model, which excels in preserving
spatio-temporal coherence during video generation. The DropletVideo dataset and
model are accessible at https://dropletx.github.io.
