If I move ball object from left to right, it looks like it is lagging. It is not smooth.
Is this FPS issue, where I can change FPS of my video ? (I'm on default settings now)

Anyone else noticed non-smooth animation ? 

Yes, it could be.
How is your FPS number?
If the FPS is very high it will be not smooth.

kylelee - I'm fairly sure you've got this back to front.  All other things being equal, less frames per second (FPS) will lead to a more jittery display, while a higher FPS should be smoother.

esanpostilaatikko - I wonder if you might be trying to move the object too far in the given time.  Or, to look at it the other way around, if you might not be giving the move long enough for it to display smoothly.  Can you show us an example or describe it in more detail?

Or, maybe the problem is your computer.  The default playback quality will be limited and frames dropped if you don't have enough processor power available - for example, if your computer is old or if you have a ton of other processes running in the background.  This would make it look jittery.  The default on-screen playback seems to target 60 FPS – that's what I'm getting with an empty project, so there's no overhead in rendering it in realtime.  If it's not turned on by default, you can display the FPS you're getting when you preview your project by checking View > On-screen Display > FPS.  Turning that on would let you know what performance you're getting for your project.

So, you've got no direct control over the effective playback FPS there.  But that's just for while you're working with your project.

When you export/render the output video file, you can specify the frame rate you want.  Say you have a 10 second animation and you output your video at a frame rate of 5 FPS.  It will generate 10x5=50 frames in your video.  However, if you then output it again at a frame rate of, say, 60 FPS, it will have to generate 10x60=600 frames for that same 10 second video.  Instead of dropping frames, it will take longer to render, but will still take only 10 seconds to playback (and will play back much more smoothly, assuming your computer has a good enough processor and graphics system).

Hope this makes sense?
