Problems with optical flow

[HeZheng]

I checked the optical flow between two neighboring frames in a video, and the result is:

[tensor([[[[[ 10.2950,   0.7181,  -4.7409,  ...,   3.1726,   6.1062,

          [[-31.9163, -33.5100, -46.0788,  ..., -57.1201, -48.2610,

Is there any problem with this result?
