How to reconstruct the frame? #88

Closed zhipeng-fan closed 3 years ago

zhipeng-fan commented 3 years ago

Hi! How would I reconstruct the frame using the motion vector, residual, and the initial I frame? I tried to warp the initial I frame of. the GOP according to the accumulated motion vector and then add the residual, but the results look weird somehow.

Problem solved. Using the MV wrongly.

@zhipeng-fan how did you reconstruct the frame? I also tried to reconstruct the frame, but my results show some strange artifacts.

Hi, did you successfully reconstruct the frame?
