Query: FILM: Frame Interpolation for Large Motion   We present a frame interpolation algorithm that synthesizes multiple
intermediate frames from two input images with large in-between motion. Recent
methods use multiple networks to estimate optical flow or depth and a separate
network dedicated to frame synthesis. This is often complex and requires scarce
optical flow or depth ground-truth. In this work, we present a single unified
network, distinguished by a multi-scale feature extractor that shares weights
at all scales, and is trainable from frames alone. To synthesize crisp and
pleasing frames, we propose to optimize our network with the Gram matrix loss
that measures the correlation difference between feature maps. Our approach
outperforms state-of-the-art methods on the Xiph large motion benchmark. We
also achieve higher scores on Vimeo-90K, Middlebury and UCF101, when comparing
to methods that use perceptual losses. We study the effect of weight sharing
and of training with datasets of increasing motion range. Finally, we
demonstrate our model's effectiveness in synthesizing high quality and
temporally coherent videos on a challenging near-duplicate photos dataset.
