Videos contain various types and strengths of motions that may look
unnaturally discontinuous in time when the recorded frame rate is low. This
paper reviews the first AIM challenge on video temporal super-resolution (frame
interpolation) with a focus on the proposed solutions and results. From
low-frame-rate (15 fps) video sequences, the challenge participants are asked
to submit higher-framerate (60 fps) video sequences by estimating temporally
intermediate frames. We employ the REDS VTSR dataset derived from diverse
videos captured in a hand-held camera for training and evaluation purposes. The
competition had 62 registered participants, and a total of 8 teams competed in
the final testing phase. The challenge winning methods achieve the
state-of-the-art in video temporal superresolution.

本文回顾了第一届 AIM 视频时间超分辨率（帧插值）挑战赛，并重点介绍了提出的解决方案和结果。该竞赛在涉及各种类型和强度的运动的 15 fps 视频序列中，要求挑战者通过估计中间帧提供更高帧率（60 fps）的视频序列。使用从手持相机中捕获的各种视频制成的 REDS VTSR 数据集进行培训和评估。在竞争中，有 62 位注册参与者，有 8 个团队参加了最终的测试阶段。挑战获胜方法达到了视频时间超分辨率的最高水平。
