Video frame interpolation, the task of synthesizing new frames in between existing ones, is a classic problem in the video processing domain. Even though there have been many ideas on how to address frame interpolation throughout the decades, it remains a challenging task with many unsolved problems. At the same time, the better frame interpolation methods become the more applications for frame interpolation emerge, which is driving research efforts into addressing more and more of the remaining challenges. This talk will provide an overview of the recent research on frame interpolation, show what frame interpolation can be used for aside from the immediately apparent applications, and conceptualize future opportunities of video frame interpolation
