Is it possible to ouput optical flow instead of midpoint flow using latest version?

Hi, I saw the issue #278 , however In my opinion rife_m model provided in older version lacks the quality which is provided in latest versions. My question is how to do it using lets say version 4.12?

The methods are similar. In Flownet.py, the first value returned by model inference is the optical flow list. Just take flow_list[-1][:, :2].

okay, what about the timestamp parameter? shall I set it to 1.0 or 0.0?

[hzwer]

Set it to 1.0. Then flow[:, :2] will be F1->0 (Theoretically speaking)

[MichalTurek]

and if i set timestamp to 0 then i will get f0->1
?

[hzwer]

flow[:, :2] is Ft->0, flow[:, 2:4] is Ft->1
Set timestep to 1.0. Then flow[:, :2] will be F1->0, flow[:, 2:4] will be F1->1
Set timestep to 0. Then flow[:, :2] will be F0->0, flow[:, 2:4] will be F0->1
