Before buying my first camera I've been watching many videos on youtube, however there is a tech spec I don't get it. Every digital camera footage I've seen there is some "slight friction force" as tilting or panning, sorry for this methaphor but it looks like the camera itself is almost drunk while it's trying to see what is around.
 
I edited three shots repeating three times each one(I don't own the footages but I will delete them as soon as they serve myself for educational purpose).
 
 

 

pS.: These were shot on an expensive(expensive if compared to DSLR cameras) Sony FS100 even so there is still this annoying "friction force" making a jerky, uneven movement. 

 

The funny thing is I barely see this "friction force" on 16mm and 35mm, they flow smooth. Besides many differences between film and digital I care much more about this "friction force" because I want to shoot exclusively music videos and specs. 
  
Sorry for my english.

You may be referring to the effect of a rolling shutter, which is usually found on many CMOS cameras.  http://en.wikipedia....Rolling_shutter
