I fooled myself. The 24p and 25p content is juddering in 8bit too.The best experience is achieved with matching mannualy the refresh rate of the content.
With 24p content i put 48hz.
With 25p content i put 50hz.
On the other hand with standalone movies i found a software that is called SmoothVideo Project
Also seems that this software contain a program that capture youtube links and transfer them to my favourite media player so it can do a framerate conversion to 60fps or higher in realtime.
Update: The SVP program in conversion is actually doubling the original FPS of the clip
so 24fps original --- > 47.95 fps
25 fps orginal ----> 50 fps
30 fps original --- > 60 fps
