Optical flow Result is Inconsistent for Same Video Inputs

I’m trying out deepstream-nvof-test sample on T4 platfrom using DeepStream 5.0.

I noticed that when my input is multiple uri using same video source, the output optical flow visulization still have slight difference between streams.

May I know is this normal?

could you please provide setup info as other topics?

Thanks! We are looking into this issue.

No difference is seen for the same stream URI. See the output video, https://www.dropbox.com/s/osym27qiai5ncw1/IMG_0697.MOV?dl=0
