Google patents video trick to smooth out missing frames
Google describes a method for creating a missing video frame by blending the frame before it with the frame after it. The system uses a single motion hint for the whole image to guess how objects moved, which helps fill in the gap more accurately than standard methods.
In the filing’s own words
A frame-level motion vector is used for motion compensation prediction of a generated (e.g., temporally interpolated picture) reference frame to improve the prediction quality of the generated reference frame when it is used as a display frame in a direct mode. The reference frame is generated for a current frame encoded to a bitstream using a backward reference frame of the current frame and a forward reference frame of the current frame. A determination is made to use the generated reference frame as a display frame in place of the current frame. Based on the determination, a prediction is generated for the generated reference frame using a frame-level motion vector signaled within the bitstream. A frame reconstruction is produced based on the prediction and output within an output video stream.
What exactly they claim (claim 1)
1. A method for prediction using a frame-level motion vector, the method comprising: generating, for a current frame encoded to a bitstream, a reference frame using a backward reference frame of the current frame and a forward reference frame of the current frame; determining to use the generated reference frame as a display frame in place of the current frame; generating, based on the determination, a prediction for the generated reference frame using a frame-level motion vector signaled within the bitstream; producing a frame reconstruction based on the prediction; and outputting the frame reconstruction within an output video stream.
