Why would there be a lack of blur? The 24fps (say) footage will start with more blur as the shutter speed will be slower and this blur will remain when interpolated to 60fps. It would surely have a physically impossibly high amount of blur after interpolation.
- dagmx 4y agoInterpolation doesn’t change shutter angle which is what causes motion blur to have a specific aesthetic look, so when interpolated it looks wrong for the frame rate. You’re right in that it doesn’t change the amount of blur, I’m not sure why the person you’re replying to thinks that. But it does change the aesthetic of the blur. Perhaps they’re thinking of the issue with the Hobbit where the higher frame rate at a given shutter angle (180 let’s say) that shortened the blur compared to a traditional 24 fps film. They adjusted this for the second hobbit film to leave the shutter open longer (not a 360 shutter, but something like a 270) to bring back some of that feeling.
