Slowing down clips in post in never as good as doing it in camera. If you've shot something at 25 fps and what to slow it down to 50 fps, your NLE will have to create the missing 25 frames, the only way it can do this is by repeating frames; hence the juddery effect of post created slow motion. The only way to do proper slow motion is shoot it with a camera that does the high frame rates you want.

Best way is to use a proper slow-mo camera. Best way to cheat it is to shoot with a high shutter speed (to reduce motion blur) and use the Twixtor plug-in, or maybe its Adobe Premiere analogue, Optical Flow. Twixtor doesn't repeat frames to fill in gaps, rather it morphs between frames to fill in gaps.

You could try the optical flow and frame blending settings on FCPX (may work in Premier) when slowing down footage.

When I do a fake slo mo I shoot at 50 frames with a faster shutter speed to reduce blur and double it in premiere (optical flow) to the equivalent of 100fps .Basically double the frame rate so 60 - 120 etc. Results aren't to bad.

The faster shutter speed reduced blur is important though as that crispness allows the software ( either optical flow, twixtor etc) to get a clearer morph between the shots.

For half speed slow motion shoot 720/50p and conform it to 25 (in premiere just drop into a 25p timeline and change speed to 50%, not sure about Da Vinci but there are a few tutorials online if you Google it). For higher frame rates (slower motion) you'd be better with a different camera. The GH5 is about £1600 and can do up to 180fps.
