Motion Tween Vibrates and I don't want it to

I am using a motion tween and several masks to go from left to right. The image vibrates or steps as it goes from left to right. Are there any tricks or tips that will help me prevent the vibrating or stepping.

The movie can be found at:

Any help you guys can give me is greatly appreciated.

Increase the frame rate and make the tween longer so you get the same speed.

What is a good frame rate to use? I am at 23 FPS now - thought that was high enough. How much will increasing the FPS effect the file size?

Thanks

The FPS does not affect file size.

23 fps should be enough but if the Flash player actually can play 23fps depends on your computer and what the object that is moving is made of. This looks like a transparent png which will make it harder for Flash to animate as it includes a alpha channel. Normal bitmaps is smoother.

yeah, try raising the framerate to 30 and expanding the movie to span more frames.. this should give it a smoother motion..

If i change it to a normal bitmap as mentioned above as opposed to a transparent PNG as it exists now can I still maintain the transparent background?

Thanks again to everyone for the help.

ummm nope.. bmp isn't interlaced.. I think you could save it as a jpg in interlaced format and it might retain it's background transparency.. but your png should be fine.. why would you want to change it to a bmp?

This is what the previous post said. I am looking for a smoother tween or transition. After reading the post below i was under the impression that a Bitmap would make the transition smoother.

Yes it probably would as there is no alpha channel. But you seem to need the transparency.
