Moving an attachment using a plugin?

Hi everybody, i was wondering if anybody knows if there is a plugin for moving an animation inserted in a video.
Atm i'm doing it manually but it takes a lot of time and it doesn't move smoothly most of the time.

Ill be very grateful with any tip.

greetings!!

IF I understand you correctly, TrackX is what you need.

Hi FCPX.guru, first of all I would like to thank you for the reply. What I'm looking for it actually much easier i guess. I might have been not so clear. I'm attaching small animations to my video ( for instance a small jpg of a dog) and I would like to know if there is another way of moving the picture from left to right inside my video than doing it manually.

Thanks in advanced

Ah, OK, so I'd recommend looking into "AddMotion" (FxFactory). But there is one that did motion paths with behaviors from Motion, that I REALLY like, but I don't have it here at home, it's at the TV station, and I don't remember the name... Oh, I got it, "mBehavior" from MoitonVFX. It is ten bucks more than AddMotion but is more sophisticated, IMHO.
