Quote - Thanks. i was trying to use video for refrence an animation of a character move.

 

Any advice on how to do it? 

Your best bet is to see first if there are any tutorials on using backgrounds with animations for Studio 4, using Bing or Google for that may bring up several different forums and sites that can provide information for you on that.  You may want to see if you can find the pdf file for Studio and see if they have something like that in their product manual as well.  Another avenue- post a thread on the daz3D.com forums and direct it toward the admins or the vendors on a chance that someone there may have already done what you have in mind.

If you do, you may want to go into specifics on what you want to accomplish other than what you've stated here.  They will want to know more.
