Optical Flow - Interlaced footage BUG
Since upgrading to Premiere Pro 2020, slowing down footage using optical flow on Interlaced footage doesn't work properly.
Interlaced clip - Slow down an interlaced clip to 10% speed with optical flow and it stutters on playback and is un-usable.
Progressive clip - works fine
Interlaced clip embedded in a progressive sequence. Slow down progressive sequence - seems to work.
Works fine on Premiere CC 2019 using the same clips etc. Interlaced and Progressive slow down no problems!
