I created a pdoject with VP15 (built 361) and opened it with VP16 (build 261).
In the original project, I added a mediafx (color correction using DFT 3rd party plugin) to some of the video files. When I open the same project in VP16, there is no mediafx but the color correction is there on the preview and render.
Video files are 1080-50i, GPU 1070ti latest driver, windows 10 1709.
Can anyone repro?
