Here's an interesting video that Nitsan has shared to help smooth out your video slider movements. By using the Konova Slider with Crank Handle Kit (seen here), a weight is added in place of the Crank Arm. The momentum of the spinning weight prevents jerky movements or harsh stop/starts. As mentioned in the video, it's best to use a balanced weight. Another modification was to flip the belt pulley backwards so that it's operating on the smooth side. Great little tip, and it makes a bit of sense. Let me know if you guys try this out and leave some comments below.
Konova Sliders and the Crank Handle Kit can both be found on the product page (here)

Pure genius !
I just sold my crank kit because I found it to be useless while spinning the handle... this looks to be a much better use! I wonder if there's a way to diy the whole thing.
