Using Premier Pro CC and through the speed/duration menu i have reversed the clip and it plays back choppy but also exports as choppy. Dont know WTF im supposed to do with that. Was trying to change field option and change and time interpolation in different combinations but its not working, video is still choppy. Im using GPU acceleration. Hardware: GTX 1060, 8GB RAM.
Convert the reversed footage to ProRes, see if it fixes it.
If it doesn't, switch to software only render, and see if this fixes it.
Delete the cached files around the problem section each time.
If it's a big complex project, render the reversed bit only in software, then insert the exported reversed files and switch back to hardware rendering.
