I'm trying to experiment with Twixtor plugin for FCPX and I am seeing the 'twixtored' video pause every second or so even when fully rendered.
Video: 60p 1/4000 from a Canon T2i
Twixtor settings: Smart blend on, slowed down to 7%, everything else set as default.
I've tried letting FCPX create the project settings (which sets to 59.9f fps) and I've tried a new project set manually to 60 fps. I also looked frame by frame to see if there are any duplicated frames in the original video and it seemed like every frame was different.
