[julio-oua]

When i run flowframes 1.40 it gives me no interpolated frames and just went straight 2 seconds time of interpolating usually it takes 40mins - 2 hours for 60fps to 480fps and after that it gave me this messages, however when i run flowframs 1.36 it begin run completely normal. well 1.40 did run normally few weeks ago but now it does this i dont know why.
