Recent advances in deep generative models have lead to remarkable progress in
synthesizing high quality images. Following their successful application in
image processing and representation learning, an important next step is to
consider videos. Learning generative models of video is a much harder task,
requiring a model to capture the temporal dynamics of a scene, in addition to
the visual presentation of objects. While recent attempts at formulating
generative models of video have had some success, current progress is hampered
by (1) the lack of qualitative metrics that consider visual quality, temporal
coherence, and diversity of samples, and (2) the wide gap between purely
synthetic video data sets and challenging real-world data sets in terms of
complexity. To this extent we propose Fr\'{e}chet Video Distance (FVD), a new
metric for generative models of video, and StarCraft 2 Videos (SCV), a
benchmark of game play from custom starcraft 2 scenarios that challenge the
current capabilities of generative models of video. We contribute a large-scale
human study, which confirms that FVD correlates well with qualitative human
judgment of generated videos, and provide initial benchmark results on SCV.

近年来，深度生成模型在图像合成方面取得了可观的进展，但在视频领域的学习则更为困难，需要模型同时捕获场景的时间动态和对象的视觉呈现。该研究提出了用于评价视频生成模型的新评价度量 - Fréchet Video Distance，并提供了基于 StarCraft 2 的新的视频生成模型挑战基准进行了大规模的人体研究和初始基准结果。
