I’m not an expert by any means, but I always disable resampling because it does remove ghosting. And in my case has nothing to do with any sort of frame rate conversions. I record game footage off of my TV from my console. And when I run that with resampling the outcome is a very muddy blurry video because there is literally so much moving on screen that its just a mess. Disabling resampling drops frames or w/e but it doesnt introduce new ones which is good when the video is full of jerky movements, and constant stuff going on in the screen.
Resampling in my mind would be good for someone who wanted a steadier video shot from a handheld camera to reduce camera shake/jerkiness or something. But I’m no expert on this, just my 2 cents.
